These years ,people have proposed several anonymous based electronic voting schemes ,however there isstill some security weakness in them. In this paper ,a improved scheme is put forward in which we use the technologyof multi_blind signature to prevent the probable cheating of visa officials ,propose a kind of confirmable serial NO to i-dentify the ballots and introduce custodians to supervise the work of ballots collector. So the scheme can resolve suchproblems as"vote collision","visa officials' fraud"and"voter quit in the midway",which exit in quite a lot of schemesof this type.
