This book constitutes the thoroughly refereed conference proceedings of the 4th International Conference on E-Voting and Identity, VoteID 2013, held in Guildford, UK, during July 17-19, 2013. The 12 revised full papers presented were carefully selected from 26 submissions. The papers include a range of works on end-to-end verifiable election systems, verifiably correct complex tallying algorithms, human perceptions of verifiability, formal models of verifiability and, of course, attacks on systems formerly advertised as verifiable.
