text: Design science is a fundamental research stream that contends its position
in the information systems discipline. While ongoing debates address the relative
importance of design science contributions in the information systems community,
insights into the scientific impact of design science research (DSR) are missing
and this lack of understanding arguably poses challenges to an informed discourse.
To identify the most influential papers and those factors that explain their scientific
impact, this paper presents an exploratory study of the scientific impact of DSR
papers published in the AIS Senior Scholars' Basket of Journals. We uncover the
current DSR landscape by taking stock of influential papers and theories and develop
a model to explain the scientific impact of DSR papers. Our findings show that
scientific impact is significantly explained by theorization and novelty. We discuss
how the implications of our work can be projected on the overarching discourse
on DSR.

text: 'Literature reviews (LRs) are recognized for their increasing impact in the
information systems literature. Methodologists have drawn attention to the question
of how we can leverage the value of LRs to preserve and generate knowledge. The
panelists who participated in the discussion of ?Standalone Literature Reviews
in IS Research: What Can Be Learnt from the Past and Other Fields?? at ICIS 2016
in Dublin acknowledged this significant issue and debated a) what the IS field
can learn from other fields and where IS-specific challenges occur, b) how the
IS field should move forward to foster the genre of LRs, and c) what best practices
are to train doctoral IS students in publishing LRs. This article reports the
key takeaways of this panel discussion. Guidance for IS scholars is provided on
how to conduct LRs that contribute to the cumulative knowledge development within
and across the IS field to best prepare the next generation of IS scholars.'

text: Multi-attribute value theory (MAVT)-based recommender systems have been proposed
for dealing with issues of existing recommender systems, such as the cold-start
problem and changing preferences. However, as we argue in this paper, existing
MAVT-based methods for measuring attribute importance weights do not fit the shopping
tasks for which recommender systems are typically used. These methods assume well-trained
decision makers who are willing to invest time and cognitive effort, and who are
familiar with the attributes describing the available alternatives and the ranges
of these attribute levels. Yet, recommender systems are most often used by consumers
who are usually not familiar with the available attributes and ranges and who
wish to save time and effort. Against this background, we develop a new method,
based on a product configuration process, which is tailored to the characteristics
of these particular decision makers. We empirically compare our method to SWING,
ranking-based conjoint analysis and TRADEOFF in a between-subjects laboratory
experiment with 153 participants. Results indicate that our proposed method performs
better than TRADEOFF and CONJOINT and at least as well as SWING in terms of recommendation
accuracy, better than SWING and TRADEOFF and at least as well as CONJOINT in terms
of cognitive load, and that participants were faster with our method than with
any other method. We conclude that our method is a promising option to help support
consumers' decision processes in e-commerce shopping tasks.

text: CAPTCHAs are challenge-response tests that aim at preventing unwanted machines,
including bots, from accessing web services while providing easy access for humans.
Recent advances in artificial-intelligence based attacks show that the level of
security provided by many state-of-the-art text-based CAPTCHAs is declining. At
the same time, techniques for distorting and obscuring the text, which are used
to maintain the level of security, make text-based CAPTCHAs diffcult to solve
for humans, and thereby further degrade usability. The need for developing alternative
types of CAPTCHAs which improve both, the current security and usability levels,
has been emphasized by several researchers. With this study, we contribute to
research through (1) the development of two new face recognition CAPTCHAs (Farett-Gender
and Farett-Gender&Age), (2) the security analysis of both procedures, and (3)
the provision of empirical evidence that one of the suggested CAPTCHAs (Farett-Gender)
is similar to Google's reCAPTCHA and better than KCAPTCHA concerning effectiveness
(error rates), superior to both regarding learnability and satisfaction but not
effciency.

text: Many academic disciplines - including information systems, computer science,
and operations management - face scheduling problems as important decision making
tasks. Since many scheduling problems are NP-hard in the strong sense, there is
a need for developing solution heuristics. For scheduling problems with setup
times on unrelated parallel machines, there is limited research on solution methods
and to the best of our knowledge, parallel computer architectures have not yet
been taken advantage of. We address this gap by proposing and implementing a new
solution heuristic and by testing different parallelization strategies. In our
computational experiments, we show that our heuristic calculates near-optimal
solutions even for large instances and that computing time can be reduced substantially
by our parallelization approach.

text: Cloud computing promises the flexible delivery of computing services in a
pay-as-you-go manner. It allows customers to easily scale their infrastructure
and save on the overall cost of operation. However Cloud service offerings can
only thrive if customers are satisfied with service performance. Allow-ing instantaneous
access and flexible scaling while maintaining the service levels and offering
competitive prices poses a significant challenge to Cloud Computing providers.
Furthermore services will remain available in the long run only if this business
generates a stable revenue stream. To address these challenges we introduce novel
policy-based service admission control mod-els that aim at maximizing the revenue
of Cloud providers while taking in-formational uncertainty regarding resource
requirements into account. Our evaluation shows that policy-based approaches statistically
significantly out-perform first come first serve approaches, which are still state
of the art. Furthermore the results give insights in how and to what extent uncertainty
has a negative impact on revenue.

text: The protection of information technology (IT) has become and is predicted
to remain a key economic challenge for organizations. While research on IT security
investment is fast growing, it lacks a theoretical basis for structuring research,
explaining economic-technological phenomena and guide future research. We address
this shortcoming by suggesting a new theoretical model emerging from a multi-theoretical
perspective adopt-ing the Resource-Based View and the Organizational Learning
Theory. The joint appli-cation of these theories allows to conceptualize in one
theoretical model the organiza-tional learning effects that occur when the protection
of organizational resources through IT security countermeasures develops over
time. We use this model of IT security invest-ments to synthesize findings of
a large body of literature and to derive research gaps. We also discuss managerial
implications of (closing) these gaps by providing practical ex-amples.

text: 'Nowadays, providing employees with failure-free access to various systems,
applications and services is a crucial factor for organizations? success as disturbances
potentially inhibit smooth workflows and thereby harm productivity. However, it
is a challenging task to assign access rights to employees? accounts within a
satisfying time frame. In addition, the management of multiple accounts and identities
can be very onerous and time consuming for the responsible administrator and therefore
expensive for the organization. In order to meet these challenges, firms decide
to invest in introducing an Identity and Access Management System (IAMS) that
supports the organization by using policies to assign permissions to accounts,
groups, and roles. In practice, since various versions of IAMSs exist, it is a
challenging task to decide upon introduction of an IAMS. The following study proposes
a first attempt of a decision support model for practitioners which considers
four alternatives: Introduction of an IAMS with Role-based Access Control RBAC)
or without and no introduction of IAMS again with or without RBAC. To underpin
the practical applicability of the proposed model, we parametrize and operationalize
it based on a real world use case using input from an expert interview.'

text: Literature reviews play an important role in the development of knowledge.
Yet, we observe a lack of theoretical underpinning of and epistemological insights
into how literature reviews can contribute to knowledge creation and have actually
contributed in the IS discipline. To address these theoretical and empirical research
gaps, we suggest a novel epistemological model of literature reviews. This model
allows us to align different contributions of literature reviews with their underlying
knowledge conversions - thereby building a bridge between the previously largely
unconnected fields of literature reviews and epistemology. We evaluate the appropriateness
of the model by conducting an empirical analysis of 173 IS literature reviews
which were published in 39 pertinent IS journals between 2000 and 2014. Based
on this analysis, we derive an epistemological taxonomy of IS literature reviews,
which complements previously suggested typologies.

text: Natural disasters, including earthquakes, Tsunamis, floods, hurricanes, and
volcanic eruptions, have caused tremendous harm and continue to threaten millions
of humans and various infrastructure capabilities each year. In their efforts
to take countermeasures against the threats posed by future natural disasters,
the United Nations formulated the ?Hyogo Framework for Action?, which aims at
assessing and reducing risk. This framework and a global review of disaster reduction
initiatives of the United Nations acknowledge the need for information systems
research contributions in addressing major challenges of natural disaster management.
In this paper, we provide a review of the literature with regard to how information
systems research has addressed risk assessment and reduction in natural disaster
management. Based on the review we identify research gaps that are centered around
the need for acquiring general knowledge on how to design IS artifacts for risk
assessment and reduction. In order to close these gaps in further research, we
develop a research agenda that follows the IS design science paradigm.

text: In double-sided markets for computing resources an optimal allocation schedule
among job offers and requests subject to relevant capacity constraints can be
determined. With increasing storage demands and emerging storage services the
question how to schedule storage jobs becomes more and more interesting. Since
such scheduling problems are often in the class NP-complete an exact computation
is not feasible in practice. On the other hand an approximation to the optimal
solution can easily be found by means of using heuristics. The problem with this
attempt is that the suggested solution may not be exactly optimal and is thus
less satisfying. Considering the two above mentioned solution approaches one can
clearly find a trade-off between the optimality of the solution and the efficiency
to get to a solution at all. This work proposes to apply and combine heuristics
in optimization to gain from both of their benefits while reducing the problematic
aspects. Following this method it is assumed to get closer to the optimal solution
in a shorter time compared to a full optimization.

text: In a world, where more and more businesses seem to trade in an online market,
the supply of online services to supply the ever-growing demand could quickly
reach its capacity limits. Online service providers may find themselves maxed
out at peak operation levels during high-traffic timeslots but too little demand
during low-traffic timeslots, although the latter is becoming less frequent. At
this point not only deciding which user is allocated what level of service becomes
essential, but also the magnitude of the service provided, can be controlled by
pricing. Pricing is an important factor when efficient and acceptable allocation
of resources between individuals must be reached. Without prices, transferring
or sharing goods would be impossible. In sharing information, pricing a product
however is not as simple as relatively pricing an apple or a pear. Often the costs,
and hence the prices are simply unknown. Backed by this scenario, the online services
market could be combined with the market design mechanism of diamonds. For this
we propose an ultimatum pricing strategy which effectively allows for valuations
to be accounted for, but no longer a necessity when pricing in grid, cloud or
other online computing environments.

text: Emerging digital environments and infrastructures, such as distributed services
and computing services, have generated new options of communication, information
sharing, and resource utilization in past years. Different distributed trust concepts
are applied to increase trust in such systems. However, these concepts yield to
rather complex architectures which make it difficult to determine which component
or system needs to be trusted. This paper presents a novel trust measurement method
for distributed systems which enables the t identification of weak points in the
overall system architecture. The measurement method includes the specification
of a formal trust language and its representation by means of propositional logic
formulas. The applicability of the proposed concepts is demonstrated by conducting
a case study on the Internet voting system that was used in the 2007 parliamentary
elections in Estonia.

text: While many theoretical arguments against or in favor of open source and closed
source software development have been presented, the empirical basis for the assessment
of arguments and the development of models is still weak. Addressing this research
gap, this paper presents the first comprehensive empirical investigation of published
vulnerabilities and patches of 17 widely deployed open source and closed source
software packages, including operating systems, database systems, web browsers,
email clients, and office systems. The empirical analysis uses comprehensive vulnerability
data contained in the NIST National Vulnerability Database and a newly compiled
data set of vulnerability patches. The results suggest that it is not the particular
software development style that determines the severity of vulnerabilities and
vendors? patching behavior, but rather the specific application type and the policy
of the particular development community, respectively.

text: 'Enduring doubts about the value of IS investments reveal that IS researchers
have not fully managed to identify and to explain the economic benefits of IS.
Three research tasks are essential requisites on the path towards addressing this
criticism: the synthesis of knowledge, the identification of lack of knowledge,
and the proposition of paths for closing knowledge gaps. This paper considers
each of these tasks by a) synthesizing key research findings based on a comprehensive
literature review, b) identifying and unfolding key limitations of current research,
and c) applying a decision-theoretic perspective, which opens new horizons to
IS business value research and shows paths for overcoming the limitations. The
adoption of this perspective results in a decision-theoretic foundation of IS
business value research and includes the proposition of a consistent terminology
and a research model that frames further research.'

text: This paper presents a fuzzy set based decision support model for taking uncertainty
into account when making security investment decisions for distributed systems.
The proposed model is complementary to robabilistic approaches and useful in situations
where probabilistic information is either unavailable or not appropriate to reliably
predict future conditions. We ?rst present the speci?cation of a formal security
language that allows to specify under which conditions a distributed system is
protected against security violations. We show that each term of the security
language can be transformed into an equivalent propositional logic term. Then
we use propositional logic terms to de?ne a fuzzy set based decision model. This
optimization model incorporates uncertainty with regard to the impact of investments
on the achieved security levels of components of the distributed system. The model
also accounts for budget and security constraints, in order to be applicable in
practice.

text: Enduring doubts about the value of IS investments reveal that IS researchers
have not fully managed to identify and to explain the economic benefits of IS.
This paper assumes that literature reviews, which represent a powerful instrument
for the identification and synthesis of knowledge, have not tapped their full
potential to address this issue due to deficiencies in methodology. The analysis
of 18 literature reviews published in pertinent academic outlets during the past
20 years shows such deficiencies. Two of the most critical weaknesses identified
are (1) the lack of theory use in most reviews and (2) a weak linkage of reviews,
resulting in little progress in theory and framework development. The systematic
identification of these weaknesses and the extraction of promising methodological
examples from past literature are the main contributions of this work, which supports
the composition of more effective literature reviews in future research.

text: The economic relevance of information systems has been studied for many years
and has attracted an abundance of research papers. However, the ?productivity
paradoxon? of the 90s, Carr?s widely recognized paper ?IT doesn?t matter?, and
several studies that do not find a positive correlation between IS investments
and economic performance reveal long-lasting difficulties for IS researchers to
explain ?IS business value?. Business executives and researchers also continue
to question the value of IS investments. This raises the question of whether literature
reviews have tapped their potential to address the concerns by covering key research
areas of IS business value and preserving their key findings. In order to address
this question, this paper identifies and describes 12 key research areas, and
synthesizes what literature reviews published in pertinent academic outlets have
done to preserve knowledge. The analysis of 22 literature reviews shows that some
crucial areas have not been (sufficiently) covered. They provide fertile areas
for future literature reviews. As this work is based on the results of more than
200 research papers, it is capable of drawing a comprehensive picture of the current
state-of-the-art in IS business value research.

text: Der Beitrag diskutiert die kontroversen Ans{\"a}tze ? Verifizierung versus
Evaluation/Zertifizierung ? zur Sicherung elektronischer Wahlen mit Wahlger{\"a}ten.
Dabei spielt das Urteils des Bundesverfassungsgerichts [BVG099] eine zentrale
Rolle. Hierin wird entschieden, dass die Zertifizierung des Wahlger{\"a}tes nicht
ausreicht und es werden Verifizierungsfunktionen gefordert, die den W{\"a}hlern
die M{\"o}glichkeit geben sich von der Integrit{\"a}t des Wahlergebnisses zu {\"u}berzeugen.
Der Beitrag zeigt auf, dass auch mit der Implementierung entsprechender Verifizierungsfunktionen
nicht auf Zertifizierung verzichtet werden kann, da an ein Wahlger{\"a}t auch
andere Anforderungen wie etwa hinsichtlich des Wahlgeheimnisses gestellt werden.
Es wird au{\ss}erdem die Frage diskutiert, warum der Zertifizierung hinsichtlich
dieser zus{\"a}tzlichen Anforderungen vertraut werden kann, w{\"a}hrend dies nicht
der Fall bei der Integrit{\"a}tsanforderung ist.

text: Remote voting through the Internet provides convenience and access to the
electorate. At the same time, the security concerns facing any distributed application
are magnified when the task is so crucial to democratic society. In addition,
some of the electoral process loses transparency when it is encapsulated in information
technology. In this paper, we examine the public record of three recent elections
that used Internet voting. Our specific goal is to identify any potential flaws
that security experts would recognize, but may have not been identified in the
rush to implement technology. To do this, we present a multiple exploratory case
study, looking at elections conducted between 2006 and 2007 in Estonia, Netherlands,
and Switzerland. These elections were selected as particularly interesting and
accessible, and each presents its own technical and security challenges. The electoral
environment, technical design and process for each election are described, including
reconstruction of details which are implied but not specified within the source
material. We found that all three elections warrant significant concern about
voter security, verifiability, and transparency. Usability, our fourth area of
focus, seems to have been well-addressed in these elections. While our analysis
is based on public documents and previously published reports, and therefore lacking
access to any confidential materials held by electoral officials, this comparative
analysis provides interesting insight and consistent questions across all these
cases. Effective review of Internet voting requires an aggressive stance towards
identifying potential security and operational flaws, and we encourage the use
of third party reviews with critical technology skills during design, programming,
and voting to reduce the changes of failure or fraud that would undermine public
confidence.

text: The increasing availability and deployment of open source software in personal
and commercial environments makes open source software highly appealing for hackers,
and others who are interested in exploiting software vulnerabilities. This deployment
has resulted in a debate ?full of religion? on the security of open source software
compared to that of closed source software. However, beyond such arguments, only
little quantitative analysis on this research issue has taken place. We discuss
the state-of-the-art of the security debate and identify shortcomings. Based on
these, we propose new metrics, which allows to answer the question to what extent
the review process of open source and closed source development has helped to
fix vulnerabilities. We illustrate the application of some of these metrics in
a case study on OpenOffice (open source software) vs. Microsoft Office (closed
source software).

text: While many theoretical arguments against or in favor of open source and closed
source software development have been presented, the empirical basis for the assessment
of arguments is still weak. Addressing this research gap, this paper presents
a comprehensive empirical investigation of the patching behavior of software vendors/communities
of widely deployed open source and closed source software packages, including
operating systems, database systems, web browsers, email clients, and office systems.
As the value of any empirical study relies on the quality of data available, this
paper also discusses in detail data issues, explains to what extent the empirical
analysis can be based on vulnerability data contained in the NIST National Vulnerability
Database, and shows how data on vulnerability patches was collected by the author
to support this study. The results of the analysis suggest that it is not the
particular software development style that determines patching behavior, but rather
the policy of the particular software vendor.

text: Reviewing literature on open source and closed source security reveals that
the discussion is often determined by biased attitudes toward one of these development
styles. The discussion specifically lacks appropriate metrics, methodology and
hard data. This paper contributes to solving this problem by analyzing and comparing
published vulnerabilities of eight open source software and nine closed source
software packages, all of which are widely deployed. Thereby, it provides an extensive
empirical analysis of vulnerabilities in terms of mean time between vulnerability
disclosures, the development of disclosure over time, and the severity of vulnerabilities,
and allows for validating models provided in the literature. The investigation
reveals that (a) the mean time between vulnerability disclosures was lower for
open source software in half of the cases, while the other cases show no differences,
(b) in contrast to literature assumption, 14 out of 17 software packages showed
a significant linear or piecewise linear correlation between time and the number
of published vulnerabilities, and (c) regarding the severity of vulnerabilities,
no significant differences were found between open source and closed source.

text: The Estonian parliamentary election in 2007 is regarded as a success story
of large-scale Internet elections. I use this election in a single case study
on practical security to show that low quality of security and its management
does not necessarily prevent large-scale Internet elections from being conducted.
I also provide research propositions with regard to future challenges for large-scale
Internet elections.

text: Spamming remains a form of Internet abuse, which burdens the Internet infrastructure,
is generally regarded as an annoyance, and is said to cause a huge economic harm.
Many technological, organizational, and legislative anti-spam measures have already
been proposed and implemented, but have not led to any substantial decrease in
the number of spam e-mails. We propose a scalable and flexible infrastructure
framework that integrates several anti-spam measures and that features both a
technological and an organizational facet. The key element of our infrastructure
is a new organizational unit that reliably and transparently limits the number
of e-mails that can be sent per day and per account. We also analyze the proposed
framework in terms of its theoretical effectiveness, the required resources, and
its limitations.

text: More than half of world-wide e-mail traffic ? an estimated total of several
billion e-mails per day ? consists of spam. This is becoming a considerable disturbance
to telecommunications. Spam is also closely related to other kinds of cyber crime
as it possibly contains malicious software or is pursuing some kind of fraudulent
aim, such as phishing. Besides technical and organizational measures, many countries
have introduced anti-spam legislation. However, today's world-wide legislative
coverage of spam is heterogeneous, and its effectiveness is controversially discussed.
This article describes important parameters by which anti-spam legislation can
vary and gives an overview and analysis of world-wide anti-spam legislation, including
the European Directive 2002/58/EC, the U.S. CANSPAM Act of 2003, and international
cooperation, such as the London Action Plan. The article then proceeds to discuss
the effectiveness of current laws, and it identifies problems resulting from the
fact that an international phenomenon is being addressed by national legislation.
Finally, the article presents suggestions for overcoming some of these problems.

text: Spamming remains a form of Internet abuse, which burdens the Internet infrastructure,
is generally regarded as an annoyance, and is said to cause economic harm to the
tune of about several billion US\$ per year. Many technological, organizational,
and legislative anti-spam measures have already been proposed and implemented,
but have not led to any substantial decrease in the number of spam e-mails. We
propose here a new infrastructure framework that combines several anti-spam measures
in a framework that features both a technological and an organizational facet.
The key element of our infrastructure is a new organizational unit that reliably
and transparently limits he number of e-mails that can be sent per day and per
account. This paper first gives an overview of the framework, then it provides
technological and organizational details of the infrastructure, the deployment
of which depends to a large degree on its acceptance and propagation by the ICANN,
the ISOC, and by large e-mail service providers. Finally, the paper discusses
the limitations and drawbacks of the proposed framework.

text: Spam e-mails have become a serious technological and economic problem. Up
to now, by deploying complementary anti-spam measures, we have been reasonably
able to withstand spam e-mails and use the Internet for regular communication.
However, if we are to avert the danger of losing the Internet e-mail service in
its capacity as a valuable, free and worldwide medium of open communication, anti-spam
activities should be performed more systematically than is currently the case
regarding the mainly heuristic, anti-spam measures in place. A formal framework,
within which the existing delivery routes that a spam e-mail may take, and anti-spam
measures and their effectiveness can be investigated, will perhaps encourage a
shift in methodology and pave the way for new, holistic anti-spam measures. This
paper presents a model of the Internet e-mail infrastructure as a directed graph
and a deterministic finite automaton and draws on automata theory to formally
derive the spam delivery routes. The most important anti-spam measures are then
described. Methods controlling only specific delivery routes are evaluated in
terms of how effectively they cover the modeled e-mail infrastructure; methods
operating independently of any particular routes receive a more general assessment.

text: 'Email communication is encumbered with a mass of email messages which their
recipients have neither requested nor require. Even worse, the impacts of these
messages are far from being simply an annoyance, as they also involve economic
damage. This manuscript examines the resource ?email addresses?, which is vital
for any potential bulk mailer and spammer. Both a methodology and a honeypot conceptualization
for implementing an empirical analysis of the usage of email addresses placed
on the Internet are proposed here. Their objective is to assess, on a quantitative
basis, the extent of the current harassment and its development over time. This
?framework? is intended to be extensible to measuring the effectiveness of address-obscuring
techniques. The implementation of a pilot honeypot is described, which led to
key findings, some of them being: (1) Web placements attract more than two-thirds
(70\%) of all honeypot spam emails, followed by newsgroup placements (28.6\%)
and newsletter subscriptions (1.4\%), (2) the proportions of spam relating to
the email addresses? top-level domain can be statistically assumed to be uniformly
distributed, (3) More than 43\% of addresses on the web have been abused, whereas
about 27\% was the case for addresses on newsgroups and only about 4\% was the
case for addresses used for a newsletter subscription, (4) Regarding the development
of email addresses? attractiveness for spammers over time, the service ?web sites?
features a negative linear relationship, whereas the service ?Usenet? hows a negative
exponential relationship. (5) Only 1.54\% of the spam emails showed an interrelation
between the topic of the spam email and that of the location where the recipient?s
address was placed, so that spammers are assumed to send their emails in a ?context
insensitive? manner. The results of the empirical analysis motivate the need for
the protection of email addresses through obscuration. We analyze this need by
formulating requirements for address obscuring techniques and we reveal to which
extent today?s most relevant approaches fulfill these requirements.'

text: Spam e-mails have become a serious technological and economic problem. So
far we have been reasonably able to resist spam e-mails and use the Internet for
regular communication by deploying complementary anti-spam approaches. However,
if we are to avert the danger of losing the Internet email service as a valuable,
free, and worldwide medium of open communication, anti-spam activities should
be performed more systematically than is done in current, mainly heuristic, anti-spam
approaches. A formal framework within which the modes of spam delivery, anti-spam
approaches, and their effectiveness can be investigated, may encourage a shift
in methodology and pave the way for new, holistic anti-spam approaches. This paper
presents a model of the Internet e-mail infrastructure as a directed graph and
a deterministic finite automaton, and draws on automata theory to formally derive
the modes of spam delivery possible. Finally the effectiveness of anti-spam approaches
in terms of coverage of spamming modes is assessed.

text: Spam has become one of the most annoying and costly phenomenon in the Internet.
Valid e-mail addresses belong to the most valuable resources of spammers, but
little is known about spammers? behavior when collecting and harvesting addresses
and spammers? capabilities and interest in carefully directed, consumer-oriented
marketing have not been explored yet. Gaining insight into spammers? ways to obtain
and (mis)use e-mail addresses is useful in many ways, e.g. for the assessment
of the effectiveness of address obscuring techniques and the usability and necessity
of hiding e-mail addresses on the Internet. This paper presents a spam honeypot
project in progress addressing these issues by systematically placing e-mail addresses
in the Internet and analyzing received e-mails. The honeypot?s conceptual framework,
its implementation, and first empirical results are presented. Finally, an outlook
on further work and activities is provided.

text: Voting via the Internet has become a feasible option for political as well
as non-political ballots. However, there are many obstacles which have to be overcome,
especially legal restrictions have to be transformed into technical and security
solutions. The article starts with a brief presentation of advantages and disadvantages
of Internet ballots and presents application fields and pilot schemes. Then, technological
security aspects are derived due to democratic basic principles. Especially the
applied voting procedures are critical in security terms. Hence, the most relevant
cryptographic protocols are presented and their drawbacks and shortcomings are
identified. However, this article does not propose a new voting protocol. Beyond
fixing cryptographic procedures for ballots, more elements are to be specified,
e.g. responsibilities and rights of involved authorities or security precautions
regarding hardware and software. For this reason, a structural security framework
for electronic voting systems is presented which can be used for their composition
and analysis.

text: Spam als unerwünschte Massen-E-Mail hat die Grenze von der Belästigung zur
ökonomischen Relevanz längst überschritten. Ihr relativer Anteil am gesamten,
weltweiten E-Mail-Aufkommen stieg in den vergangenen Jahren auf mehr als 50% im
Jahr 2003. Es entstehen jährlich volkswirtschaftliche Schäden in Milliardenhöhe.
Zur Bekämpfung des Spam-Problems werden neben gesetzlichen Regelungen vor allem
technische Lösungen eingesetzt, bei denen das Blockieren und Filtern von E-Mails
in praktisch eingesetzten Anti-Spam-Systemen dominieren. Dieser Artikel führt
in die Spam-Problematik ein und beschreibt, bewertet und klassifiziert die derzeit
bedeutendsten Verfahren zur Bekämpfung von Spam.

text: Spam as unsolicited e-mail to a large number of recipients is known to ecome
an increasingly disturbing and costly issue of electronic business and internet
traffic. Mainly technical-oriented approaches are applied with a focus on blocking,
filtering, and authentication mechanisms based on the domain name system. They
come along with different drawbacks and have all low effectiveness in common.
The article sketches these approaches, shows its limitations, and proposes an
account-based approach where the number of e-mails per day and account is restricted.

text: Voting via the Internet is part of electronic government and electronic democracy.
However, there are many obstacles which have to be overcome, especially legal
restrictions have to be transformed into technical and security solutions. In
the first part the article discusses advantages and disadvantages of Internet
elections, shows different application fields, and presents important international
pilot schemes (political and business ones). in the second part, due to democratic
basic principles, technological security aspects are worked out.

text: 'Zusammenfassung: Im Rahmen des E-Governments werden zunehmend Internetwahlen
diskutiert. Der Beitrag diskutiert zunächst die Vor- und Nachteile derartiger
Wahlen und zeigt Anwendungsgebiete sowie durchgeführte Pilotprojekte im politischen
wie auch wirtschaftlichen Bereich auf. Im Rahmen eines Anforderungssystems werden
anschließend aus demokratischen Wahlgrundsätzen sicherheitstechnologische Anforderungen
herausgearbeitet. Zu deren Adressierung werden kryptographischen Wahlkonzepte
herangezogen, von denen die wichtigsten vorgestellt werden. Aufgrund der Komplexität
der Anforderungslandschaft wird ein sicherheitstechnologisches Strukturmodell
vorgestellt, das insbesondere dazu dient, die Sicherheit(skomponenten) eines Wahlsystems
systematisch mit den Anforderungen abzugleichen. Der Artikel schließt mit einem
Ausblick auf notwendige Untersuchungen.'

text: Bei der Online-Marktforschung lässt sich mit Hilfe virtueller 3D-Welten das
Konsumentenverhalten beobachten. Da die Struktur der dabei anfallenden Daten multidimensional
ist und die marktforschungsrelevanten Anfragen eine hohe OLAP-Affinität aufweisen,
wurde hierzu im Rahmen des Forschungsprojekts Benevit ein Data Warehouse konzipiert
und realisiert. Im Rahmen einer Standardisierung der Protokollierung von Konsumentenaktivitäten
und deren prototypischen Realisierung erwies sich der Data Warehouse/OLAP-Ansatz
zur Speicherung, Analyse und Präsentation der Marktforschungsdaten als adäquates
Instrumentenbündel.

text: 'Mit dem elektronischen Papier wird in der Displayforschung ein neuer materialtechnologischer
Ansatz verfolgt: Elektronisches Papier besteht aus einer dünnen, flexiblen Folie,
in der farbige Pigmente mittels elektrischer Felder ausgerichtet werden. Die Vorteile
gegenüber traditionellen Technologien wie beispielsweise LCD-Displays bestehen
zum einen in niedrigeren Herstellungskosten (niedrigere Produktionskosten und
geringere Materialkosten) und einem geringeren Gewicht. Zum anderen entsteht eine
bessere Lesbarkeit, da sich Reflexion, Kontrast und mögliche Betrachtungswinkel
verbessern bzw. vergrößern. Diese Potenziale können bei Anzeigetafeln, Computerdisplays
und mobilen Endgeräten ausgeschöpft werden. Mit der Eigenschaft, fast beliebige
Materialien als Trägermedium zu verwenden, öffnet sich auch die Anwendungsmöglichkeit
des biegsamen, elektronischen Mediums für Zeitungen und Zeitschriften. Die US-Unternehmen
E Ink und Gyricon Media bieten eine zunehmend größere Produktpalette mit elektronischem
Papier an.'
