This applies to paper-based as well as electronic elections. However, in Germany, legal requirements on retention in e-voting have not been issued so far. Based on the German legal framework for governmental as well as non-governmental paper-based elections, we give recommendations on long-term retention in e-voting, applying our results to a state-of-the-art e-voting scheme. We also review technical measures to meet the security requirements of long-term retention in e-voting. 2008-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/29195 The E-Voting Readiness Index Krimmer, Robert; Schuster, Ronald Krimmer, Robert; Grimm, Rüdiger The goal of this study is to analyse and compare the environment for the introduction of E-Voting. To do so a contextual model is developed and then applied with the value benefit analysis to compare 31 countries including all EU member states, and Russia, Switzerland, United States and Venezuela. 2008-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/29193 Secure Remote Voter Registration Morales-Rocha, Victor; Puiggalí, Jordi; Soriano, Miguel Krimmer, Robert; Grimm, Rüdiger Voter registration is an important issue in election processes. In order to protect the election accuracy, it is necessary to have an accurate electoral roll of eligible voters. The electoral roll is usually constructed by means of a voter registration system that compiles voter data either in person or remotely. Current solutions for remote voter registration lack effective methods to prevent impersonation, multiple registrations and alterations on voter information. In this paper we propose a remote voter registration scheme that increases the accuracy of the current systems. In this scheme the voter identification is carried out by means of some biometric systems. Biometrics is also used to prevent impersonation, detect multiple registrations from the same person and protect from alterations of the registration information. 2008-01-01T00:00:00Z http://dl.gi.de/handle/20.500.12116/29190 Assessing the Impact of E-Voting Technologies on Electoral Outcomes: an Analysis of Buenos Aires’ 2005 Congressional Election Katz, Gabriel; Alvarez, R. Michael; Calvo, Ernesto; Escolar, Marcelo; Pomares, Julia Krimmer, Robert; Grimm, Rüdiger Using data from an e-voting experiment conducted in the 2005 Congressional Election in Argentina, we estimate the effect of different e-voting technologies on the likelihood that citizens cast their vote for different parties for the National Congress and the Legislature of Buenos Aires. Our results indicate that voters are extremely receptive to the information cues provided by the different voting technologies and associated ballot designs, and that particular voting devices have a significant impact on voter choice, systematically favouring some parties to the detriment of others. We conclude that the choice of alternative electronic voting devices might have considerable effect on electoral outcomes in multi-party electoral systems. 2008-01-01T00:00:00Z
