Electronic voting in Estonia

The idea of having electronic voting in Estonia gained popularity in 2001 with the "e-minded" coalition government. Estonia became the first nation to hold legally binding general elections over the Internet with their pilot project for the municipal elections in 2005. The electronic voting system withstood the test of reality and was declared a success by Estonian election officials. The Estonian parliamentary election in 2007 also used internet voting, another world first.

Although the term Power voting (or e-voting) can refer to both fixed voting locations (as in voting booths) and remote (as in over the Internet) electronic voting, in Estonia the term is used exclusively for remote Internet voting. The security model is modeled after the way in which advance voting and postal voting is handled.

The Estonian internet voting system builds on the Estonian ID card. The card is a regular and mandatory national identity document as well as a smart card allowing for both secure remote authentication and legally binding digital signatures by using the Estonian state supported public key infrastructure. As of March 2007 over 1.08 million cards have been issued (out of a population of about 1.32 million).

Internet voting is available during an early voting period (sixth day to fourth day prior to Election Day). Voters can change their electronic votes an unlimited number of times, with the final vote being tabulated. It is also possible for anyone who votes using the Internet to vote at a polling station during the early voting period, invalidating their Internet vote. It is not possible to change or annul the electronic vote on the Election Day.
