Abstract: The present invention describes a method and system for protecting the integrity and authorship of a piece of registration information of the user, applicable in voter information registration, by means of biometric techniques. To that end, after a first stage of entering a piece of registration information, a second stage of protecting the integrity of the registration information is implemented. In this second stage, an item of integrity proof of said information is generated and said item of integrity proof is displayed to the user who wishes to protect it. In a third stage of generating an item of non-repudiation proof of the registration information, an item of biometric proof of the user which contains the item of integrity proof displayed is obtained, an item of non-repudiation proof is constructed from said item of biometric proof, and finally the item of non-repudiation proof is stored.

Abstract: The invention relates to an auditable method and system for generating a verifiable vote record that is suitable for electronic voting. The inventive method is characterized in that a voting module, an audit module and a verification module perform the following steps in which: voting options are selected by the voter in the voting module; the voting options are sent from the voting module to the audit module; a vote record is generated in the verification module which contains the voting options selected by the voters in the voting module; the voter confirms that the vote record contains the voting options that s/he selected in the voting module by direct verification of the vote record; and audit information is generated in the audit module in order to secure the electronic vote and/or the associated vote record which are both generated from the voting options selected and confirmed by the voter.
