    Implementing and evaluating a software-independent voting system for polling station elections2014In: Journal of Information Security and Applications, ISSN 2214-2134, E-ISSN 2214-2126, Vol. 19, no 2, p. 1-10Article in journal (Refereed)
    Abstract [en]

    In 2009 the German Federal Constitutional Court introduced the principle of “public nature of elections” (Federal Constitutional Court of Germany, March 2009). This principle requires that when using electronic voting systems it must be possible for the citizen to verify the essential steps in the election process and in the ascertainment of the results reliably and without special expert knowledge. Unfortunately, none of the existing systems complies with this principle. As a result, the use of electronic voting systems in Germany for parliamentary elections has stopped. Nevertheless, electronic voting systems are necessary and would improve the situation, especially for elections with complex ballots and voting rules, for example some local elections in Germany or parliamentary elections in Belgium and Luxembourg. The concept proposed by Volkamer et al. (Volkamer et al., 2011) was analyzed by a legal expert and evaluated to comply with the German legal requirements for local elections in the state of Hesse (Henning et al., 2012). In this paper we specify and concretize processes that were left open in the concept, and implement a prototype. We evaluated this prototype in a user study that was conducted alongside the university elections at the Technische Universtität Darmstadt in June 2013. The results of the study show that most of the participants were satisfied with the prototype and would support its use for the upcoming university elections. We also report some lessons learned.

    The simpler, the better? Presenting the COPING Android permission-granting interface for better privacy-related decisions2017In: Journal of Information Security and Applications, ISSN 2214-2134, E-ISSN 2214-2126, Vol. 34, no 1, p. 8-26Article in journal (Refereed)
    Abstract [en]

    One of the great innovations of the modern world is the Smartphone app. The sheer multitude of available apps attests to their popularity and general ability to satisfy our wants and needs. The flip side of the functionality these apps offer is their potential for privacy invasion. Apps can, if granted permission, gather a vast amount of very personal and sensitive information. App developers might exploit the combination of human propensities and the design of the Android permission-granting interface to gain permission to access more information than they really need. This compromises personal privacy. The fact that the Android is the globally dominant phone means widespread privacy invasion is a real concern.

    We, and other researchers, have proposed alternatives to the Android permission-granting interface. The aim of these alternatives is to highlight privacy considerations more effectively during app installation: to ensure that privacy becomes part of the decision-making process. We report here on a study with 344 participants that compared the impact of a number of permission-granting interface proposals, including our own (called the COPING interface — COmprehensive PermIssioN Granting) and two Android interfaces. To conduct the comparison we carried out an online study with a mixed-model design.

    Our main finding is that the focus in these interfaces ought to be on improving the quality of the provided information rather than merely simplifying the interface. The intuitive approach is to reduce and simplify information, but we discovered that this actually impairs the quality of the decision. Our recommendation is that further investigation is required in order to find the “sweet spot” where understandability and comprehensiveness are maximised
