2 to 8, first, in the manager terminal 130, the election information (eg, an election or a voting list) to be voted by the voter is generated together with a decryption key (or a plurality of vote counting keys), Send the generated decryption key to the administrator's email (or mobile phone) (or send each generated ballot counting key to the email (or , mobile phone)) and provides the generated election information to the electronic voting providing server 140 . Accordingly, the electronic voting server 140 registers the election information received from the manager terminal 130 in the database (S201).

After registering the election information in the above-described step S201, the manager terminal 130 encrypts the voter information (eg, the voter's mobile phone number or e-mail address, etc.) having the right to vote through the voter Excel input to vote electronically. It is provided to the provision server 140 . Accordingly, the electronic voting server 140 registers the voter information received from the manager terminal 130 in the database (S202).

After registering the voter information in the above-described step S202, when the designated voting time comes, the manager terminal 130 generates voting start information to inform the start of voting along with the final designation of candidate information to provide an electronic voting server ( 140) is sent. Accordingly, in the electronic voting server 140, according to the voting start information received from the manager terminal 130, the voter does not come to the polling place directly at home, school, or a space where the Internet is available (or a space where mobile communication is possible) In order to be able to vote, an election site previously designated by the election commission or the like is provided to the voter terminal 110 through the voting network 160 .

Then, in the voter terminal 110 , which is an Internet-capable communication terminal such as a PC, a laptop computer, a PDA, a smart phone, a mobile phone, etc., the electronic voting server 140 accesses a designated election site provided through the voting network 160 . do.

For example, in the voter terminal 110 , it is possible to directly access an election site address through an Internet web browser opened by the voter, or to an election site linked to a banner through a home page, and also a smartphone or mobile device. When accessing using a tablet or the like, it is possible to automatically connect to a corresponding mobile election site.

For another example, in the voter terminal 110, a notification text for notifying the voters is provided from the electronic voting providing server 140, and an election linked when an election site address included in the notification text is clicked. You can also connect to the site.

Then, the electronic voting providing server 140 checks the voter terminal 110 (eg, the address of the voter terminal 110 , a unique identifier, etc.) accessed through the designated election site to be online (or mobile ) voting compliance matters (or information on the voting procedure) will be provided to the confirmed voter terminal 110 . Accordingly, the voter terminal 110 receives the online voting compliance information (or information including the voting procedure) through the designated election site and displays it as shown in FIG. 3 ( S203 ).

In the online voting compliance matters displayed in step S203 as described above, the voter clicks the consent for the online voting compliance matters as shown in FIG. 3 through an input means (eg, a point by a mouse, etc.) When done, the voter terminal 110 generates consent information for informing that the voter agrees to the online voting observances according to the voter's consent input and provides it to the electronic voting providing server 140 . Then, the electronic voting providing server 140 checks the consent information received from the voter terminal 110 and provides the login window information to the voter terminal 110 .

Accordingly, the voter terminal 110 displays the login window information (or a click window for inputting the candidate promise view) received from the electronic voting providing server 140 as shown in FIG. 4 ( S204 ).

In the login window displayed in step S204 as described above, when a voter inputs their own login information (ie, ID and password) through an input means (eg, a touch panel, a keypad, etc.), the voter The terminal 110 encrypts the received login information and provides it to the electronic voting server 140 .

For example, in the voter terminal 110, the voter's own name and student number input by the voter may be provided to the electronic voting providing server 140 through a login click, and also electronic voting when the candidate's pledge view is clicked A promise of a candidate may be received from the providing server 140 and displayed.

Then, the electronic voting server 140 receives and decrypts the login information from the voter terminal 110, checks whether the decrypted login information is registered in the voter information stored in the database, and the confirmed voter information to perform voter authentication for the voter terminal 110 by using (S205).

For example, when the voter authentication in step S205 described above is an authentication method through the mobile phone SMS, the electronic voting providing server 140 provides the voting authentication window information to the voter terminal 110 . Accordingly, the voter terminal 110 may display the voting authentication window information (or a click window for inputting an authentication number) received from the electronic voting providing server 140 as shown in FIG. 5 . Accordingly, when the voter inputs his/her mobile phone number through the input means and then clicks Receive authentication number, the voter terminal 110 encrypts the received mobile phone number and authentication number request information for electronic voting It may be provided to the providing server 140 . Then, the electronic voting server 140 receives the mobile phone number and authentication number request information from the voter terminal 110 , randomly generates a voting authentication number, and sends the generated vote authentication number to the mobile phone number of the voter by SMS will be sent to Accordingly, when the voter enters the vote authentication number received through SMS through the voter terminal 110 and then clicks the vote authentication confirmation, the voter terminal 110 receives the vote authentication number and the vote authentication confirmation request information may be transmitted to the electronic voting server 140 . Accordingly, the electronic voting providing server 140 may verify whether or not the voter is legitimate by checking whether the voting authentication number received from the voter terminal 110 and the previously generated voting authentication number match.

For another example, if the voter authentication in step S205 described above is an authentication method through e-mail, the electronic voting providing server 140 provides the voting authentication window information to the voter terminal 110 . Accordingly, the voter terminal 110 may display the voting authentication window information (or a click window for inputting an authentication number) received from the electronic voting providing server 140 as shown in FIG. 5 . Accordingly, when the voter enters his/her own e-mail address through the input means and then clicks Receive Authentication Number, the voter terminal 110 encrypts the received e-mail address and the authentication number request information to receive an electronic voting It may be provided to the providing server 140 . Then, the electronic voting providing server 140 receives the email address and authentication number request information from the voter terminal 110 to randomly generate a voting authentication number, and sends the generated voting authentication number to the voter's email address as a message (e-mail) will be sent. Accordingly, when the voter enters the voting verification number received through the e-mail through the voter terminal 110 and then clicks the voting verification confirmation, the voter terminal 110 requests the received voting verification number and voting verification confirmation Information may be transmitted to the electronic voting providing server 140 . Accordingly, the electronic voting providing server 140 may verify whether or not the voter is legitimate by checking whether the voting authentication number received from the voter terminal 110 and the previously generated voting authentication number match.

After the voter authentication is performed 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 . Accordingly, the voter terminal 110 displays the election information (ie, the election list confirmation window and voting window 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, when a voter selects a list to be elected and clicks start voting, then selects a candidate and clicks voting, the voter terminal 110 receives the input By encrypting the voter's vote value information and providing it to the electronic voting server 140, this online electronic voting method (or mobile electronic voting method) is efficient because it is not limited by time and place, and a large number of people ( voters) can vote at the same time, saving money and time.

For example, in the voter terminal 110, the voter may select one of the list of affiliated department oath, college election, and student council president election displayed through an input means and click start voting. Accordingly, the electronic voting providing server 140 may display the candidate voting page corresponding to the selected list through the voter terminal 110 . At this time, in the voter terminal 110, when the voter puts his/her mouse on the candidate on the displayed candidate voting page, it can be displayed in a faint stamp shape. It can be chosen as you go. And, in the voter terminal 110, it may be possible to click abstention in order to be reflected as abstention in the voting result, and also to click the next button to perform a vote for another election list.

For example, in the case of a single candidate, in the electronic voting providing server 140, the voter terminal 110 displays a candidate voting page for clicking on voting completion after selecting one of the votes for and against by clicking one of the voters terminal 110 It can also be displayed through .

The electronic voting server 140 receives and decodes the vote value information from the voter terminal 110, and then transmits the decoded vote value information to the block chain server 170 without recording and processing the vote. Accordingly, in the block chain server 170, upon receiving the voting value information transmitted from the electronic voting providing server 140, it generates a voting block including the received voting value information and all storage devices on the block chain network 190 After transmission to 180, the voting block verified through mutual verification of information in the storage device 180 is combined with the chain to complete voting. And in the storage device 180, the voting value information transmitted from the block chain server 170 is shared with each other and stored so that data forgery or falsification cannot be performed by collating this information (S207).

For example, in the block chain server 170, the voting value information received from the electronic voting providing server 140 is put in a voting block and connected in a chain form, and a plurality of storage devices 180 using a distributed data storage technology ) can be copied and saved at the same time. At this time, the storage device 180 may prevent hacking by performing mutual verification on the voting value information transmitted from the block chain server 170 .

After the voting block is chain-coupled in the above-described step S207 to complete the voting, the electronic voting server 140 reads the voting completion information for notifying the completion of the voting from the database and provides it to the voter terminal 110 . Accordingly, the voter terminal 110 displays the voting completion information received from the electronic voting server 140 as shown in FIG. 8 (S208).

For example, the voter terminal 110 may automatically log out after outputting a voice saying "voting is complete" when voting is completed, and also automatically the time the elector (voter) voted , authentication number, etc. can be recorded as a log.

After the end of voting as in step S208, the electronic voting server 140 waits until the preset voting completion time is reached, and when the voting completion time comes, the voting value information is sent to the block chain server 170 to request Accordingly, the block chain server 170 receives a request for voting value information from the electronic voting server 140 and transmits the voting value information stored in the storage device 180 to the electronic voting server 140 . Then, the electronic voting server 140 receives the voting value information from the block chain server 170, aggregates the voting results, and collects voting information (eg, voter turnout for each election, voting progress by region, and each winner and voter turnout for each election). , information on aggregation results for each candidate through detailed aggregation view, etc.) is calculated and registered in the database (S209).

After registering the voting information in step S209 described above, the manager terminal 130 waits until the preset voting completion time arrives, and when the voting completion time arrives, the manager terminal 130 receives a decryption key from the manager. (or to receive each counting key from multiple voters), check whether it matches the previously generated decryption key (or check whether it matches each previously generated counting key), In this case, the ballot counting information is generated and transmitted to the electronic voting providing server 140 . Accordingly, the electronic voting server 140 provides the result view window information to the voter terminal 110 according to the ballot count information received from the manager terminal 130 .
