Description

Public electronic voting system and method, using mobile phone}

The present invention is a secret ballot in which personal information is not exposed, and the present invention makes it possible to check the number of voters and transparently check my voting information and other people's voting information. It relates to an open electronic voting method and system.

Nowadays, since business is handled online, much of the organization's business process is done online. However, for important decision-making, it is necessary to attend and make a decision, such as a general meeting. However, the problem here is that due to the nature of many members or work, the quorum for decision-making is frequently insufficient because it is distributed to many places.

In order to solve this problem, many electronic voting systems have been proposed, most of which are proposals related to personal authentication for verifying voters' authority. In other words, it is proposed from the perspective of the organizer and consists of a system that the voters must acknowledge.

From the standpoint of voters, this only shows the overall result of how many voters, how many voters, and what are the vote results. In other words, from the standpoint of each voter, there is a disadvantage that there is no way to verify whether my voting rights have been properly applied or that other people's voting rights have been properly applied.

The present invention is a secret ballot in which personal information is not exposed, and the present invention makes it possible to check the number of voters and transparently check my voting information and other people's voting information. It is to provide an open electronic voting method and system.

This implementation example discloses an open electronic voting system using a mobile phone.

The system of the present embodiment includes an organizer terminal receiving a voting ID from a voting management server, storing voting information in a voting information database, and storing the mobile phone numbers of voters in the database A table; A subscriber terminal for checking the voter from table A, fetching and displaying voting information from the voting information, storing the voting contents and markers received from the user in the database B table, and storing the voting facts in the database A table; A voting information database for storing voting candidate information; A database first table that stores a hash value of the phone number and whether or not there is a signature; A second database table for storing the marked contents and display characters; Including the database, it issues a voting ID, and includes a voting management server for uploading and downloading information from the database at the request of the organizer terminal and the subscriber terminal.

The method of another implementation example comprises the steps of: receiving, by the host terminal, a voting ID from the voting management server; Storing, by the host terminal, candidate information in a voting information database; Converting the mobile phone number of the voter into a hash function in the database A table by the organizer terminal and storing that the voting standby state is made using the hash function value as an address; Transmitting, by the organizer terminal, the voting ID and the hash function value to the candidate terminal; The voter terminal retrieves the mobile phone number from the mobile phone system and obtains the hash value, and if it is true, it retrieves and displays the voting candidate information from the voting information database and receives the voter and markers by inquiring whether the address with the obtained hash value exists in the database A table. step; When the voter terminal receives the voter and the mark letter from the user, the step of recording that the mark has been made in the database A table, and storing the voted content and the mark letter in the database B table; Returning the address value stored in the voter terminal from the database B table; The voter terminal storing the returned address value; It includes the step of showing both the database A table and the database B table as well as the voting information database when the organizer terminal or the voter terminal requests it.

According to this embodiment, you can easily vote through a popular mobile phone, and in particular, by using a hash value and a marker that only you know in data storage, personal information is not exposed, and all information that has been voted, i.e., my vote contents, can be checked. Including the number of voters, the number of voters, and other people's voting information can be checked transparently, there is an effect that the results can be trusted.

The present invention and the technical problem achieved by the implementation of the present invention will become more apparent by the preferred embodiments of the present invention described below. The following examples are merely illustrative for explaining the present invention, and are not intended to limit the scope of the present invention.

In this embodiment, as shown in FIG. 1, an organizer terminal 110 having voting information and voter information and equipped with an application for driving the system, and a voter terminal equipped with an application for driving the system ( 120) and a voting management server 100 that receives, transmits, and stores information from the organizer terminal and the voter terminal is configured by being connected to a communication network.

Referring to FIG. 1, the organizer terminal 110 has voting information and voter information 112, and an application 111 for driving the system is provided, and the voter terminal 120 is for driving the system. The application 121 is provided.

In addition, the voting management server 100 has a voting information database 101, a database A table 102 and a database B table 103 for each voting ID, and detailed information for each selected item is stored in the voting information database 101. In the database A table, the hash value of the voter's phone number and voting availability information are stored, and in the database B table, the content of the vote and the marking character are stored along with the ID value.

Referring to Figure 2 to describe the implementation method thereof,

Receiving, by the host terminal, a voting ID from the voting management server; Storing, by the organizer terminal, voting information in a voting information database; Converting the mobile phone number of the voter into a hash function in the database A table by the host terminal, and storing that the voting standby state is made using the hash function value as an address; Transmitting, by the organizer terminal, the voting ID and the hash function value to the candidate terminal; The voter terminal fetches his/her mobile phone number, obtains a hash value, inquires whether an address having a corresponding hash value exists in the database A table, and if true, fetches and displays voting information from the voting information database, and receives a voter and a marker; When the voter terminal receives the voter and the mark letter from the user, the step of recording that the mark has been made in the database A table, and storing the voted content and the mark letter in the database B table; Returning the address value stored in the database B table; The voter terminal storing the returned address value; When requested by the organizer terminal or the voter terminal, it consists of showing both the database A table and the database B table, including the voting information database.

There are various examples of voting, such as selecting one of several types, selecting one of several people, choosing pros and cons for a certain, etc. Here, an example of selecting among several people will be described.

2 is an operation flow diagram of an open electronic voting system using a mobile phone according to this embodiment.

Prior to the explanation, all of the following processes of organizers and voters are carried out through an application built into the owned terminal.

2, the organizer receives a voting ID from the management server (s101). Since the management server oversees several other voting management, a designated ID is required.

The organizer stores voting information, for example, names, photos, and biographies of each candidate through the organizer's terminal, together with the candidate number in the voting information database s102 as shown in FIG. 3.

In addition, when the mobile phone number of the voter is input in the application of the organizer terminal, the application obtains the hash value of the mobile phone numbers, uses the hash value as the address value, and makes a vote wait (for example, 0) in the database A table as shown in FIG. Generated and stored (s103). In addition, at the same time, the application transmits the voting ID and the hash value of each terminal to each voter terminal as shown in FIG. 5 (s104).

When the application of the voter terminal receives the hash value through the user's touch or shared connection, the mobile phone number is obtained through the self-portable number retrieval function, and the hash value is obtained and compared with the received hash value (s105). Of course, if the hash value is different here, the process is stopped. In this case, another terminal attempts to access by copying a message, so it is possible to prevent other people from exercising their voting rights.

Also, the voter application checks whether an address having a corresponding hash value exists in the database A table (s106), and if it does not exist, the process is stopped. In this case, a person who does not have the right to vote attempts access, and thus, it is possible to prevent a person who does not have the right to vote.

If everything passes, the application fetches candidate information from the server and displays it on the screen as shown in FIG. 6, and requests a signifier and a marker (s107). Here, the signifier is the number of the candidate selected from among the candidates, and the indicator is a temporary letter that the voter can know only by himself. This marker is a means to later know that it is my vote stored in the database B table.

When the application receives a voter and a marker from the voter (s108), it first stores the vote on its own hash value address in the database A table (e.g. 1) (s109), and secondly, the voter content and marker in the database B table. Save (s110). When the stored address value is returned from the database B table (s111), the application of the voter terminal stores the address value (s112).

In this way, all the voting process is over, and when the voting is over, the organizer or voter can see the results as shown in Figs. 7 and 8 when the organizer or the voter inquires the database A table and the database B table, and thus the organizer can aggregate the voting results ( s113) In particular, each voter inquires their votes (s114), checks the number of voters in database A, and checks whether or not my voting rights are properly entered through the hash value, and the total number of voters in database B It matches table A, and you can check if the marker matches and the content of the vote by looking up the address value of my vote in my table B. The reason the marker is needed here is that when receiving the address value for my signifier from the server, it is possible to return another address value with the same signifier by malicious will.

In this example, since the address (hash value) was received as (J5dj4f) in the message of FIG. 5, it can be seen that the voting right was exercised in the D/BA table of FIG. 7, and the address value returned from (s111). With (6j58fu), you can check the D/BA table in Fig. 8 to see that the marked content and the display letter match, and from the perspective of others, you do not know what my phone number is, and who I have signed. It is impossible.

As discussed above, in this embodiment

Easily vote through popular mobile phones, and in particular, by using hash values and markers that only you know for data storage, personal information is not exposed, and all information that was voted, including confirmation of my vote, number of voters, voters By making it possible to transparently check the number and other people's voting information, there is an effect that the results can be trusted.

In the above, the present invention has been described with reference to one embodiment shown in the drawings, but those of ordinary skill in the art will understand that various modifications and other equivalent embodiments are possible therefrom.
