Title:
ELECTRONIC VOTING SYSTEM
Document Type and Number:
Japanese Patent JP3209238
Kind Code:
B2
Abstract:
PURPOSE: To obtain a safe and fair electronic voting method capable of holding privacy by ciphering the contents of a vote to form a voting sentence and transmitting a disturbed voting sheet with a signature to an election supervisor.
CONSTITUTION: Respective voter devices 100 for T voters Vi are connected to an election supervisor device 200 through a register communication line 400 and connected also to a totalizer device 300 through an anonymous communication line 500. The device 300 opens a table 600 for the contents of votes. The device 100 is constituted so as to access the table 600. Since a voting sentence disturbed the contents of a vote by a random number, an election supervisor A and a totalizer C can not find out the contents of the vote from the disturbed voting sentence and unsigned voting is also guaranteed. Since a formal objection claiming a valid voter Vi is shown only by transmitting the ciphered voting sentence and the signature of the supervisor A to the totalizer C, it can be executed without clarifying the contents of the vote.
