Abstract: A ballot checker is responsible for checking of ballot in the past electronic voting schemes. The ballot checker can not tally the legitimate ballot but count illegal ones if he is not honest. For solving the problem, the author presented an electronic voting scheme based on threshold. In this scheme, checking of ballot requires some ballot checkers's cooperation in the author's scheme. This makes the result of ballot checking acceptable. Voters publish Hash or ciphertext of the ballots content and nobody can know the authentic content of these ballots. It prevents someone from forcing voters to vote and voting trading, etc.
