  • Patent number: 7054829
    Abstract: A method and system for validating the creation and submission of absentee ballots is provided. An authentication/validation mark is generated and printed on an absentee ballot and/or the envelope that contains the absentee ballot. The authentication/validation marks include information such as, for example, the date and time of printing, an identification and location of the vote validator that generated and printed the mark, a unique identifier of the mark, and a digital signature of the authentication/validation data. Upon receipt of the absentee ballot by election officials, the authentication/validation marks printed on the absentee ballot and/or envelope containing the ballot can be verified by authenticating the digital signature and verifying the validity of the data in the mark. If the mark is verified, the authenticity and creation/submission dates of the absentee ballot are guaranteed and the absentee ballot can be accepted as a valid absentee ballot for election purposes.
