Referring to FIGS. 2 to 8, first, the administrator terminal 130 generates election information (e.g., an election or a voting list) that voters must vote for together with a decryption key (or a plurality of vote counting keys). Transfer the generated decryption key to the administrator's email (or mobile phone) (or send each generated vote counting key to each vote counter (e.g., election commissioner and election commissioner) (respectively transferred to an e-mail (or mobile phone)) and provides the generated election information to the electronic voting providing server 140 . Accordingly, the electronic voting providing server 140 registers the election information received from the administrator terminal 130 in the database (S201).

After registering the election information in step S201, the administrator terminal 130 encrypts voter information (e.g., voter's mobile phone number, e-mail address, etc.) who has the right to vote through voter Excel input. Provided to the electronic voting providing server 140. Accordingly, the electronic voting providing server 140 registers the voter information received from the administrator terminal 130 in the database (S202).

When the designated voting time comes after the voter information is registered in step S202, the administrator terminal 130 generates the final designation of the candidate information and the voting start information for notifying the start of voting. It is transferred to the electronic voting providing server 140 . Accordingly, in the electronic voting providing server 140, according to the voting start information received from the manager terminal 130, the voter can access the space at home, school, or Internet (or mobile communication) without going to the polling place directly. In order to enable voters to vote in the space, an election site designated in advance by an election administration committee or the like is provided to the voter terminals 110 through the voting network 160 .

The voter terminal 110, which is a communication terminal capable of connecting to the Internet, such as a PC, a notebook, a PDA, a smart phone, a mobile phone, etc., is configured to connect to a designated election site provided by the electronic voting providing server 140 through the voting network 160. become.

For example, the voter terminal 110 can connect directly to the election site address through an Internet web browser opened by the voter, or can connect to a banner-linked election site through the home page, or use a smartphone, mobile tablet, or the like. If you use it to connect, you can also automatically connect to the corresponding mobile election site.

Further, for example, when the voter terminal 110 receives a notification letter from the electronic voting providing server 140 for notifying the voter of the vote, and clicks on the election site address included in the notification letter, the linked election site can also be connected to

Next, the electronic voting providing server 140 confirms the voter terminal 110 (e.g., the address of the voter terminal 110, unique identifier, etc.) connected through the designated election site, and determines the online (or mobile) voting requirements (or information on voting procedures) is provided to the confirmed voter terminal 110, so that the voter terminal 110 receives online voting requirements (or information including voting procedures) through the designated election site, It is displayed as shown in FIG. 3 (S203).

In the online voting rules displayed in step S203 as described above, if the voter clicks through an input means (for example, a mouse pointer) to agree to the online voting rules shown in FIG. 3, the voter terminal 110: Consent information for notifying consent to the online voting rules is generated by the voter's consent input, and provided to the electronic voting provision server 140 . Accordingly, the electronic voting providing server 140 checks the consent information received from the voter terminal 110 and provides the voter terminal 110 with login screen information.

Accordingly, the voter terminal 110 displays the login screen information (or the click screen for inputting the candidate's pledge display) received from the electronic voting providing server 140 as shown in FIG. 4 (S204).

When the voter inputs his or her login information (i.e., ID and password) through the input means (e.g., touch panel, keypad, etc.) on the login screen displayed in step S204 as described above, the voter terminal 110 displays the input information. The obtained login information is encrypted and provided to the electronic voting providing server 140 .

For example, the voter terminal 110 can provide the electronic voting server 140 with his/her name and student number entered by the voter by clicking the login button. Candidates' pledges can also be provided and shown.

After receiving and decrypting the login information from the voter terminal 110, the electronic voting providing server 140 confirms whether or not the decrypted login information is registered in the voter information stored in the database. Using the obtained voter information, voter authentication is performed on the voter terminal 110 (S205).

For example, if voter authentication in step S205 is an authentication method through SMS of a mobile phone, the electronic voting providing server 140 provides voting authentication screen information to the voter terminal 110. FIG. Accordingly, the voter terminal 110 can display the voting authentication screen information (or the click screen for inputting the authentication number reception) received from the electronic voting providing server 140 as shown in FIG. Accordingly, if a voter inputs his or her mobile phone number through the input means and then clicks Receive Verification Number, the voter terminal 110 encrypts the entered mobile phone number and verification number reception request information and electronically votes. It can be provided to the providing server 140 . Then, the electronic voting providing server 140 receives the mobile phone number and the authentication number reception request information from the voter terminal 110, randomly generates the voting authentication number, and stores the generated voting authentication number as the voter's mobile phone number. It will be forwarded by SMS. Accordingly, if the voter inputs the voter authentication number received through SMS through the voter terminal 110 and clicks on the voter authentication confirmation, the voter terminal 110 electronically sends the input voter authentication number and voter authentication confirmation request information. It can be transferred to the providing server 140 . Accordingly, the electronic voting providing server 140 checks whether the voting authentication number received from the voter terminal 110 and the previously generated voting authentication number match, and authenticates whether the voter is legitimate. be able to.

Further, for example, if voter authentication in step S205 is an authentication method through e-mail, the electronic voting providing server 140 provides voting authentication screen information to the voter terminal 110. FIG. Accordingly, the voter terminal 110 can display the vote authentication screen information (or the click screen for inputting the receipt of the authentication number) received from the electronic voting providing server 140 as shown in FIG. Accordingly, when a voter inputs his or her e-mail address through the input means and clicks on receiving the verification number, the voter terminal 110 encrypts the input e-mail address and verification number reception request information and electronically votes. It can be provided to the providing server 140 . Then, the electronic voting provision server 140 receives the e-mail address and the verification number reception request information from the voter terminal 110, randomly generates a voting verification number, and sends the generated voting verification number to the voter's e-mail address. It will be forwarded by message (email). Accordingly, if the voter inputs the voter authentication number received through the e-mail through the voter terminal 110 and clicks the voter authentication confirmation, the voter terminal 110 receives the input voter authentication number and voter authentication confirmation request information. It can be transferred to the electronic ballot delivery server 140 . Accordingly, the electronic voting providing server 140 checks whether the voting authentication number received from the voter terminal 110 and the previously generated voting authentication number match, and authenticates whether the voter is legitimate. be able to.

After the voter authentication in step S205 as described above, the electronic voting providing server 140 reads the election information for checking the election list and voting from the database and provides it to the voter terminal 110. FIG. Accordingly, the voter terminal 110 displays the election information (that is, the election list confirmation screen and the voting screen information) received from the electronic voting providing server 140 as shown in FIGS. 6 and 7 (S206).

In the election information displayed in step S206 as described above, if a voter selects a list to be elected and clicks start voting, then selects a candidate and clicks vote, the voter terminal 110 displays the input By encrypting vote value information of voters and providing it to the electronic voting provision server 140, the online electronic voting system (or mobile electronic voting system) is not restricted by time and place, so it is efficient and Many people (voters) can vote at the same time in many areas, saving money and time.

For example, on the voter terminal 110, the voter selects one of the displayed lists of the election of the department to which he/she belongs, the election of the college, and the election of the president of the general student body through the input means, and clicks start voting. be able to. Accordingly, the electronic voting providing server 140 can display the candidate voting page corresponding to the selected list through the voter terminal 110 .
