Abstract (en)

[origin: WO03069448A2] A facility for conducting a coercion-resistant electronic collection is described. The facility receives from the voter a first voter conformation value. At a later time, the facility receives from the voter an encrypted ballot and a second voter confirmation value. Without regard for the value of the received second voter confirmation value, the facility adds the received ballot to a publicly-available list of cast ballots. After the addition, members of the public are able to verify the addition of the received ballot to the list without being able to determine whether the ballot will be counted. The facility counts the ballot if and only the second voter confirmation value received with the ballot matches the received first voter confirmation value.
