Recently, many e-voting systems have been proposed for successful election. It should be satisfied many requirements for successful e-voting. In this paper, we propose the ballot-cancellation scheme in order to manage invalid ballots. Many proposed e-voting systems have been proposed without considering invalid ballots. It can be happened an invalid ballot during e-voting, and then we should co...

The rapid development of communication and information technology has made electronic voting technologically and economically feasible. In this study, we will examine the differential impact of four electronic voting system (EVS) characteristics (privacy, accessibility, mobility, and accuracy) on voter participation intention (i.e., EVS voting) and on preferred EVS mechanism (telephone, Web-bas...

Democratically choosing a single preference from three or more candidate options is not a straightforward matter. There are many competing ideas on how to aggregate rankings of candidates. However, the Gibbard-Satterthwaite theorem pessimistically concludes that no fair voting system is immune to strategic voting. In our work we analyze the likelihood of strategic voting of several popular voti...

The paper challenges the ‘orthodox doctrine’ of collective choice theory according to which Arrow’s ‘general possibility theorem’ precludes rational decision procedures generally and implies that in particular all voting procedures must be flawed. I point out that all voting procedures are cardinal and that Arrow’s result, based on preference orderings cannot apply to them. All voting procedure...

Electronic voting could increase citizens’ electoral participation and trust in countries characterized by fragile democratic institutions and public discredit of the political system such as those in Latin America. This paper examines attitudes towards e-voting among participants in a large scale pilot project conducted in Colombia in 2007, focusing on the perceived reliability and usability o...

In this paper criticality within a voting game is rigorously defined and examined. Criticality forms the basis of the traditional voting power measures frequently employed to analyse voting games; therefore understanding criticality is a pre-requisite to understanding any such analysis. The concept of criticality is extended to encompass games in which players are allowed to express multiple le...

Internet voting is highly regarded for its speed, automatic counting, cost reduction and lower possibility of error. However, in order to replace traditional voting system with internet-voting, i-voting must meet many requirements and overcome some challenges like collusion, uncoercibility, unfairness and in particular voter insecure platforms. In this paper, we propose a very practical and sec...

E-voting technology has been developed for more than 30 years. However it is still distance away from serious application. The major challenges are to provide a secure solution and to gain trust from the voters in using it. In this paper we try to present a comprehensive review to e-voting by looking at these challenges. We summarized the vast amount of security requirements named in the litera...

The widespread adoption of Information and Communication Technologies in governance over the years by electronic government has influenced democratic decision making through electronic voting (e-voting).E-voting provides increased participation of populace, reduced cost, decreased cases of invalid votes and support basis of democracy. However, e-voting systems are generally prone to security ri...

with quick development of digital images and the availability of imaging tools, massive amounts of images are created. therefore, efficient management and suitable retrieval, especially by computers, is one of themost challenging fields in image processing. automatic image annotation (aia) or refers to attaching words, keywords or comments to an image or to a selected part of it. in this paper,...
