  • Patent number: 6971574
    Abstract: Hash numbers are assigned to each individual ballot choice made by a particular voter and a hash total, establishing the voter's set of ballot choices, is recorded and a printed receipt is issued to the voter, bearing the voter's identification number, to assure him that his vote was correctly recorded along with his hash total. If the voter presents his receipt, to deny that he voted as shown on the receipt, an unfavorable comparison of the previously recorded hash total, with the hash total on the receipt, proves that the receipt was forged, and each such tampering attempt and voter ID is recorded. Recounts are unnecessary, unless the number of such recorded attempts at tampering exceed a predetermined number. A hacker attempt to change a recorded vote will fail because the hash totals of the altered ballot won't match the correct hash total because the hash encoding algorithm is secret.
