The increase of Internet penetration in the last years is boosting the popularity of eVoting systems. However, in order to have a security level similar to that of an in-person voting, a series of security requisites have to be accomplished. This article describes a secure eVoting protocol based on ring signatures. The implementation details and the different modules of a voting platform including this signature protocol are presented. In addition, a special characteristic has been included in the voting protocol: during the signature process a parameter called "linking tag" is generated, able to identify the different votes sent by a single voter during a voting process. This characteristic makes it interesting in e-Cognocracy and Quality of Experience evaluation scenarios.
