Referring to FIG. 2, the election management server 100 on the network according to the present invention includes a receiver 130, a storage 150, a sender 190, and a password generator 170.

First, the sending unit 190 sends predetermined URL information to the

voter terminals

270 and 290 used by each voter through the unique information of each voter.

The receiver 130 receives voting information from the

voter terminals

270 and 290 connected to the predetermined URL.

The cipher generator 170 generates the first cipher code by inputting the voting information received from the

voter terminals

270 and 290 and the unique information of the voter into the first function, and converts the first cipher code into the second function. Generate a second encryption code.

The storage unit 150 stores unique information of each voter necessary for wire / wireless communication with each voter, and also stores a second encryption code and voting information together. In storing the voting information, the storage unit 150 may preferably store the voting information in the form of a function value input to the asymmetric encryption function in which the encryption key and the decryption key are separated. In addition, the sending unit 190 sends the first encryption code to the voter terminal (270, 290).

3 is a flowchart illustrating an election management method on a network using a personal terminal according to the present invention. Referring to Figure 3 describes the election management method on the network using a personal terminal according to the present invention, first, the election management team obtains the email address and mobile phone number of each voter as unique information of each voter at the time of registration of the voter and makes a database; (S300).

The election management unit checks whether the mobile Internet terminal or the WAP browser is supported by the mobile phone terminal 290, which is used by each voter, through the mobile phone numbers of the respective voters databased in cooperation with each mobile carrier (S310).

The unique information including the voter's e-mail address and mobile phone number including information on whether the mobile phone terminal 290 supports the wireless Internet or the WAP browser is stored in the storage unit 150 of the election management server 100. If the mobile phone terminal 290 supports the wireless Internet or the WAP browser, the sending unit 190 of the election management server 100 sends predetermined URL information through which the mobile phone number can access the election homepage on the network. If the mobile phone terminal 290 does not support the wireless Internet or the WAP browser, it transmits predetermined URL information for accessing the election homepage on the network through an e-mail address (S320).

The voter who has received the predetermined URL information through the mobile phone terminal 290 or the computer terminal 270 accesses the URL through the mobile phone terminal 290 or the computer terminal 270 (S330). In implementing the present invention, in order to prevent the same voter from using the mobile phone terminal 290 or the computer terminal 270 to make duplicate votes, the election management server 100 provides a voter access to the URL. It is determined whether the access key used at the time is used for the previous connection (S340).

If the voter wants to vote for the second time through the mobile terminal 290, or if the voter votes through the computer terminal 270, then the voter tries to vote again through the mobile terminal 290. If the URL is connected again, the election management server 100 checks that the access key used by the voter at the time of access to the URL is used for the previous access, and blocks the voter's access (S345).

If it is determined that the access key used by the voter to access the URL is not used for the previous access, the election management server 100 determines whether the voter has completed the voting offline (S350). Specifically, the election administration sends information to the election management server 100 about the voters who voted at the polling place on the election day, and the election management server 100 based on this, whether the voter completed the voting offline. Will be judged.

If it is determined that the voter has completed the voting offline, the voting management server blocks the voter's access (S345).

If it is determined that the voter did not vote offline, the voter transmits the voting information through the election homepage on the network accessed through a predetermined URL through the mobile phone terminal 290 or the computer terminal 270 ( S360).

The website server 250 transmits the voter's voting information to the election management server 100, and the election management server 100 receives the voter's vote information from the website server 250. The password generation unit 170 of the election management server 100 generates the first encryption code by inputting the unique information and the voting information of the voter to the first one-way encryption function (S370). Here, the one-way cryptographic function may be a combination function of a plurality of one-way cryptographic functions.

On the other hand, in order to prepare for an objection due to manipulation of voting results from voters in the future, the sending unit 190 of the election management server 100 preferably sends the generated first encryption code to the

voter terminals

270 and 290. Will be (S380).

In addition, the password generation unit 170 of the election management server 100 generates a second encryption code by inputting the first encryption code to the second one-way encryption function (S385). It may be preferable that the one-way cryptographic function here is also a combined function of a plurality of one-way cryptographic functions.

Thereafter, the storage unit 150 of the election management server 100 stores the vote result table created by storing the second encryption code and the vote information for each voter (S390).

The election administration can check the election results by aggregating the voting information items of the voting result table stored in the storage unit 150 of the election management server 100, but the unique information of the voters is encrypted twice in one direction with the second encryption code. Because they are stored in the form of, the electoral officials will not be able to obtain information about who voted or who voted, thereby enabling secret elections on the network.

On the other hand, for a more complete secret election it will be desirable to delete the first encryption code, the first one-way encryption function, and the first encryption code sent history stored in the storage unit 150 of the election management server 100 (S395). ).

In addition, in order to prevent the voting information stored in the storage unit 150 of the election management server 100 from being exposed during the election, the voting information of the function value input to the asymmetric encryption function in which the encryption key and the decryption key are separated from each other. It would be desirable to store in form. In this case, after the election, the result of the voting may be confirmed by decrypting the encrypted and stored voting information with a decryption key.

On the other hand, in the above-described step S380, the election management server 100 has sent the first encryption code to the voter terminal (270, 290) in order to prepare for a problem in the future operation of the vote result from the voter, voter In the case of raising a question about the operation of the voting result, etc., the electoral management unit inputs the first encryption code stored in the

voter terminals

270 and 290 of the voter to the second one-way encryption function together with the second encryption code generated. By confirming the voter information stored in the storage unit 150 of the election management server 100 to the corresponding voter, the suspicion about the manipulation of the voting result can be resolved.

In addition, in the practice of the present invention, in order to resolve the voter's suspicion through a simpler process, the election management server 100 in the step S280, in sending the first encryption code to the voter terminal (270, 290), The voter's voting information may be sent along with the first encryption code to a function value entered in the asymmetric encryption function that is separated from the encryption key and the decryption key. In such a case, when a voter raises suspicion of an election operation, the voter's vote result can be confirmed by decrypting the voting information encrypted in the voter's

voter terminal

270 or 290 with a decryption key.

In addition, in the practice of the present invention, in order to prevent voting by using the mobile phone terminal 290 of another person or another person's e-mail account, when voting information is transmitted through the

voter terminals

270 and 290, Fingerprint information, voice information, iris information, retina information, or face information obtained through the

voter terminals

270 and 290 may be included in the voting information and transmitted. In this case, the election management server 100 stores the vote information as a valid vote only when it matches with the voter through the preparation process of fingerprint information, voice information, iris information, retina information, or face information of individual voters already stored. Will be done.
