The e-government paradigm became an essential path for governments to reach citizens and businesses and to improve service and public performance. One of the important tools used in political and administrative venues is e-voting, where ICT tools are used to facilitate the process of voting for electing representatives and making decisions. The integrity and image of such applications won't be maintained unless strict measures on security and authenticity are applied. This chapter explores the e-voting process, reviews the authentication techniques and methods that are used in this process and proposed in the literature, and demonstrates few cases of applying e-voting systems from different countries in the world. Conclusions and proposed future work are stated at the end of the chapter.
