Abstract
This paper introduces an extension to the Estonian Internet voting scheme allowing the voters to check the cast-as-intended and recorded-as-cast properties of their vote by using a mobile device. The scheme was used during the 2013 Estonian local municipal elections and the 2014 European Parliament elections. 3.43% and 4.04% of all Internet votes were verified, respectively. We will present the details of the protocol, discuss the security thereof and the results of implementation.
