To this end, the method in the present invention includes: a voting data receiving step; a data storing step; and a vote counting step.

Description

Transparency-assured voting management and counting method, device and computer-readable recording medium using blockchain {METHOD, APPARATUS AND COMPUTER-READABLE MEDIUM OF VOTING MANAGEMENT AND AGGREGATION THAT GUARANTEES TRANSPARENCY USING BLOCKCHAIN}

The present invention relates to a voting management and counting technology for election operation using a block chain method. Specifically, the voting information is stored in a physically distributed terminal in a block chain method so that the voted voting right cannot be retrieved during voting, Even if voting information is read from distributed terminals, it is possible to prevent the voter from knowing the result of the vote, and the matching relationship between the voting right and the voter is also unknown, so that complete security for voting can be obtained during the election. is about

In the block chain technology, small data called 'blocks' of managed data are stored in a chain-type, link-based distributed data storage environment created based on the P2P method, so that no one can arbitrarily modify it, and anyone can change the result of the change. It is a ledger management technology based on distributed computing technology that can view This is essentially a form of distributed data storage technology, and it is a change list that records continuously changing data to all participating nodes, and is designed to prevent arbitrary manipulation by the operator of the distributed node. Blockchain technology is used for most cryptocurrency transactions, including Bitcoin. Since the transaction process of cryptocurrency is used in a decentralized electronic ledger, a server is operated on each computer of many users running blockchain software, enabling free transactions between individuals without a central bank.

According to such desperate security, recently, blockchain technology has been used in various ways, not just in the field of financial transactions. In particular, as issues such as fraudulent elections have recently been pointed out, a secure blockchain technology-based election system operation system has been proposed as a new election method. In particular, by enabling electronic voting in the election system, it is possible to increase the turnout and to use it for various political participation and voting methods. Therefore, the need for election technology applying such block chain technology is increasing.

As such a block chain-based election technology, Korean Patent Registration No. 10-2143530 is a method of issuing a block chain wallet address to a user with voting rights and processing vote counting, and storing voting data in a block chain method Thus, a technique for increasing security has been proposed.

However, these technologies require a relatively complex blockchain-based data security technology to be applied, and the integrity that cannot be edited can be maintained. However, in order to secure the anonymity and confidentiality of the election representatives, the security of the data itself is required. Therefore, there is a problem that many high-level functions have to be applied among blockchain-based technologies. In particular, since high-level encryption technology must be applied, it is not possible to secure the characteristics of anonymous and secret elections by practically utilizing the features of separate storage for physical servers as the base technology of the block chain. is leaked, it is possible to determine which candidate a specific voter voted for, and thus, a problem relatively vulnerable to hacking has been pointed out.

Accordingly, the present invention provides a new voting technology that utilizes the distributed storage feature for multiple terminals in which security can be completely guaranteed even if encryption is not performed, that is, which candidate voted until the vote counting time. , aims to provide voting technology that increases complete anonymity, confidentiality and security in a very simple manner.

In addition, it provides technology that allows complete anonymity, confidentiality and security of voting rights without the need for complicated encryption in electoral register management and voting rights registration, so that the transparency of voting management and counting is completely guaranteed. Another purpose is to provide technology.

In order to achieve the above object, a voting management and counting method with guaranteed transparency using a block chain according to an embodiment of the present invention includes one or more processors and one or more memories for storing instructions executable in the processor It relates to a voting management and counting method that guarantees transparency using a blockchain implemented as a computing device, and when voting is performed by deciding that one of a plurality of candidates will vote from a voter account with validly issued voting rights, Voting data receiving step of receiving the first account information and the encrypted voter account information that is a candidate account; After allocating the number of votes for a plurality of candidates with respect to the voter account, voting information including voter account information and the number of votes for each candidate account is stored, but the candidate account corresponding to the first account information has the largest number of votes. Allocating a first number of votes that is the number of votes, and assigning a second number of votes smaller than the first number of votes to the second account information that is a candidate account except for the first account information for all candidates for one voter account After generating the voting information, a data storage step of storing the voting information in a plurality of distributed terminals constituting the block chain in an independent state so that comparison of at least the information of each vote is impossible; And when it is determined that voting is complete and ballot counting is performed, the voting information stored by the data storage step is collected from a plurality of distributed terminals, grouped by voter account, and the number of votes information for all candidate accounts allocated to the voter account is compared and a vote counting processing step of adding the number of votes allocated to the voter account to the cumulative number of votes of the candidate account having the largest number of votes.

It is preferable that the first number of votes and the second number of votes are randomly set within a preset natural number range.

Before the voting data receiving step, the electoral list server, a valid account determination step of determining whether the voter account can hold the voting rights validly; and when the electoral list server determines that the voter account can hold the voting right by the valid account determination step, registers the voting right authentication information for voting in the voter account and registers the voting right in the voter account step; It is preferable to further include

The voting right registration step may include: a first encryption key receiving step of receiving a first encryption key that is at least a password for voting rights from a voter account; an authentication information storage step of generating a first ID (ID) for the voter account when receiving the first encryption key, and registering the first encryption key and the first ID as authentication information; a first ID transmission step of transmitting the first ID information to the voter account; and requesting the setting of a second encryption key different from the first encryption key from the voter account, and the voting right server independent of the electoral list server receives the first ID and the second encryption key from the voter account, and the voter It is preferable to include; a voting right storage step of storing the voting rights for the account.

The voting data receiving step, when receiving the ID and password information from the voter account, through data comparison with the voting right server, the ID and password information received from the voter account with the first ID and the second encryption key In the same case, it is preferable to determine that the voting right is validly issued to the voter account.

In the voting data receiving step, when receiving the first account information and the first ID information as voting data, the first ID and the second encryption key of the voter account are obtained by an intermediary server independent of the electoral list server. Voting right encryption step of converting to a second ID other than the ID to generate the encrypted voter account information; and an encrypted voting right storing step of storing the encrypted voter account information and the first ID and the second encryption key information in the voting right server, and initializing the data of the intermediary server.

The ballot count processing step is, when grouping the voting information for each voter account, derive a first ID corresponding to the encrypted voter account through a voting right server connected for voting, and grouping the voting information by the first ID desirable.

On the other hand, the apparatus for managing and counting votes with guaranteed transparency using a block chain according to an embodiment of the present invention is a block implemented as a computing device including one or more processors and one or more memories for storing instructions executable in the processor It relates to a voting management and counting device that guarantees transparency using a chain. When voting is performed by deciding to vote among a plurality of candidates from a voter account with valid voting rights, 1 Voting data receiver for receiving account information and encrypted voter account information; After allocating the number of votes for a plurality of candidates with respect to the voter account, voting information including voter account information and the number of votes for each candidate account is stored, but the candidate account corresponding to the first account information has the largest number of votes. Allocating a first number of votes that is the number of votes, and assigning a second number of votes smaller than the first number of votes to the second account information that is a candidate account except for the first account information for all candidates for one voter account After generating the voting information, a data storage unit for storing the voting information in a plurality of distributed terminals constituting the block chain in an independent state so that comparison of at least the information of each number of votes is impossible; And when it is determined that voting is complete and ballot counting is performed, voting information stored by the data storage unit is collected from a plurality of distributed terminals, grouped by voter account, and the number of votes information for all candidate accounts allocated to the voter account is compared Thus, it is preferable to include a; vote count processing unit for adding the number of votes allocated to the voter account to the cumulative number of votes of the candidate account with the largest number of votes.

a valid account determination unit for determining whether the voter account can effectively hold voting rights; and a voting right registration unit that registers voting rights in the voter account by registering authentication information of voting rights for voting in the voter account when it is determined by the valid account determination unit that the voter account can hold the voting rights; Directory server; is preferably linked.

According to the present invention, when a voter account votes for a specific candidate, it is composed of voting for a specific number of votes for all candidates without interim counting as a vote for that candidate, and so that the highest number of votes for a specific candidate It is automatically set as the number of votes.

Accordingly, even if information on the voting result is leaked from a specific terminal due to the characteristics of the information about the number of votes that are distributed and stored, it is not possible to determine who the voter account actually voted for. It has the effect that security can be completely maintained until voting results are counted without requiring any technology, especially advanced encryption technology.

In addition, since the voter's ID and password are stored and managed differently between physically separated terminals in the registration of voting rights, the voting rights management for voters before voting is also highly secure, It has the effect of ensuring the maintainability of secret elections.

Before explaining FIGS. 1 to 4, the voting management and counting method that guarantees transparency using a block chain according to an embodiment of the present invention uses a block chain according to an embodiment of the present invention shown in FIG. Each component of the transparent voting management and counting device, the electoral list server, the voting right server, and the mediation server may be referred to as the subject of execution, respectively.

At this time, it will be understood that the above-described device and server are composed of a device group in which the computing device and computing device of FIG. 10 to be described later are grouped. In particular, when it is referred to as physically separated, it is a separate computing device, that is, It should be understood that the terminals are physically completely separated from each other.

Referring to FIGS. 1 to 4 , the computing device first determines that one of a plurality of candidates will vote from a voter account for which the voting right is validly issued and performs a vote, first account information that is a candidate account to be voted on. And performing a voting data receiving step (S30) of receiving the encrypted voter account information.

In the present invention, the voter account refers to an account having a position to vote for a specific candidate during an election by registering an account and receiving a voting right according to embodiments of FIGS. 2 to 3 to be described later. Accordingly, a voter account may be newly created and managed for each voter at each election, and the ID of the voter account may be created and managed automatically or by information input from the voter who requested the account creation.

In addition, the issuance of voting rights to the voter account means that, for example, when one vote is issued per person in an election for a national election official or member of the National Assembly, the number of votes will not be separately managed when managed as information about voting rights; In elections other than that, where, for example, voting rights differ from voter to voter, i.e., where more than one vote is assigned to a particular voter, information about the voting rights issued, registered and managed includes information about the number of votes as well as the validity of the voting rights. do.

On the other hand, the validity of the voting right is information managed through information on the validity of each voter's account and whether the voter has already voted, and is information on whether the current right to vote is valid. Of course, as described above, when the voting right is issued through each voter's personal information, the valid issuance of the voting right means that the voting right for the election in which the voter can vote is automatically determined and managed according to the voter's personal information do. For example, when a specific voter is issued a voting right, the constituency will be determined according to the voter's resident registration address, and accordingly, the constituency in which the voter can vote and the right to vote for the election will be automatically determined and issued.

In this case, the voter account may cast a vote in a state in which the voting right is validly issued as described above. At this time, the voting is performed by the voter through his/her terminal accessing the voting management and counting 10 that guarantees transparency using the block chain shown in FIG. 5, and manipulation of the voting interface output to the user terminal 20 as a result of the connection By performing selection of a specific candidate and input of voting performance through the , it means that the above-mentioned candidate to be voted and the voter account information who voted are generated.

In this case, the candidate to be voted means a candidate entered by the voter so that the candidate can vote by selecting and exercising the right to vote in a specific election. Of course, when the voter account performs a plurality of votes, each vote may be managed according to each election. For example, if an election for the National Assembly right, a district councilor, a city council member, etc. is held at the same time at a specific voting opportunity, the voter account will conduct a plurality of votes, and in this case, step S30 is a vote for each election under the data structure managed for each election described above. will be performed separately.

Encrypted voter account information does not mean that a specific encryption technology for the voter account is applied in step S30 together with the issuance and registration of voting rights, which will be mentioned in the description of FIGS. 2 and 3, which will be described later, but rather the randomization of account information and physically It means that encryption is achieved by storing information about distributed terminals.

When step S30 is completed, the computing device allocates the number of votes for a plurality of candidates to the voter account and then stores voter information including voter account information and the number of votes for each candidate account, Allocating the first number of votes, which is the largest number of votes, to the candidate account corresponding to the first account information, and allocating the second number of votes smaller than the first number of votes to the second account information that is the candidate account except for the first account information After generating the voting information for all candidates for one voter account, the voting information is stored in a plurality of distributed terminals constituting the block chain in an independent state so that at least the information of each voter cannot be compared. Step S40 is performed.

When a voter performs a vote, information on the above-described first account that becomes a voteee as a result of the voter voting is transmitted along with information on the voter account. In this case, the computing device does not store information about the first account as it is. This is because, in the case where the information about the first account is stored as it is with the information about the account, no matter how distributed and stored the information using the block chain method, the integrity is only guaranteed, so information can be leaked. This is because voting results for candidates voted by voters before counting may be leaked.

The core of the present invention is not only to secure the integrity of data to prevent manipulation of the vote, but also to completely secure the anonymity and confidentiality, which are the grand principles of the election, especially for the vote. At this time, step S40 is performed in order not to use complex encryption technology.

An example of this is shown in FIG. 9 . Referring to FIG. 9 together, when a voter performs a vote through the voter terminal 20, information on the voter account and information on the first account are transmitted as described above. At this time, through step S40, the computing device allocates the votes of the largest number of votes (5) to the candidate (C) corresponding to the first account as the first number of votes, and the second account that is the candidate account excluding the first account The information (A, B, D) is assigned a second number of votes, which is a lower number of votes (2, 3, 4) than the first number of votes.

As a result, even if the voter account votes for candidate C, voting information is created as voting for all candidates (A, B, C, D) on the data. This information is stored in a state in which it is impossible to determine which candidate the voter account voted for through the hacking of one terminal to a plurality of physically distributed distributed terminals constituting the block chain, that is, until the information is recombined and compared with each other. It is stored in an independent state where it is not possible to determine whether or not the votes were cast for which candidate the most.

On the other hand, the above-described first number of votes and the second number of votes are randomly set within a preset natural number (eg, 5) range. In other words, by allowing the number of votes to be randomly assigned under the grand principle that the number of first votes is greater than the number of votes for the second, it is impossible to hack the number of votes by understanding the rules for granting votes.

In this case, it is impossible to know at all which candidate a vote was performed until the information is recombined for the purpose of counting the votes and compared to which candidate has the highest number of votes.

That is, even if no encryption technology is applied, the confidentiality of the vote, that is, anonymity and confidentiality, is completely guaranteed through the above-described step S40, and there is an effect that intermediate counting is impossible.

After that, the computing device collects the voting information stored by the data storage step (S40) from a plurality of distributed terminals when it is determined that the voting has been completed and performs the counting, grouping them by voter account, and to all candidate accounts assigned to the voter account By comparing the number of votes information for the vote counting step (S50) of adding the number of votes allocated to the voter account to the cumulative number of votes of the candidate account with the largest number of votes is performed.

In this case, grouping by voter account should be understood as including the concept of grouping by each election when the above-described multiple elections (voting) are simultaneously performed. In step S50, the computing device compares the number of votes for all candidates assigned to the voter account for the account, and then sets the candidate account with the highest number of votes, that is, the account with the first number of votes, as the first account, and the first account The number of votes received by the candidates corresponding to

At this time, if it is not the number of votes to be compared as described above, for example, if the number of votes can be given to one voter or more, the number of votes held by the voter account in the corresponding election will be stored in the voting information, and the number of votes added at this time The number of votes cast will be the voters held by the aforementioned voter account. To this end, in step S60, information on the number of voting rights held by the above-mentioned voter may be derived together with the information on the voter account, and may be used to add the number of votes. If this step S60 is repeatedly performed for all voter accounts, the election result will be derived by the accumulation of votes.

On the other hand, in the present invention, when managing the voter account, the voter (voter) is the voter (voter) when hacking the electoral list server because the server that performs the registration of voting rights for the voter and management of the voter account manages the information of the voter account when managing the voter account. You can see whether you voted for or not, so anonymity and confidentiality may not be maintained.

In order to solve this problem, the present invention secures the security of the voter account in the registration of voting rights before performing the above-described steps S30 to S50, and prevents the voter account from matching the voting result when performing the step S30 contains

First, referring to FIGS. 2 and 3 and 7, before performing step S30, the electoral list server performs a valid account determination step (S10) of determining whether the voter account can effectively hold the voting right. This refers to a process in which the electoral service server determines whether or not the voter is capable of holding the right to vote in a specific election through authentication of an official certificate from a voter account, identification of an identification card, and the like.

After that, the number of voters server, when the voter list server determines that the voter account can hold the voting right by the valid account determination step, registers the voting right authentication information for voting in the voter account and gives the voter account the right to vote Performs a voting right registration step (S20) to register.

Step S20 refers to the process of registering for voting rights. Specifically, for setting IDs and passwords to enable voters to perform voting rights in the above-mentioned voting interface, IDs and passwords are created and encrypted. It means registering the resulting authentication information. That is, it should be understood that the authentication information in step S20 is information for authentication such as an ID and password that a voter must input in order to perform voting rights.

At this time, referring to FIGS. 3 and 7 , the voter account first performs, as a preliminary step, a voting right issuance request process (1.) for requesting registration of their own voting rights in the electoral list server 40 that manages the electoral list. At this time, in the process (2.3.3) through which the authentication number input is performed, the first encryption key receiving step of receiving the first encryption key set as the password for the voting right from the voter account (S21, 3. in FIG. 7) ) will be performed. The first encryption key includes all information (text, image, video, voice) that can be input so that the voter can use it as a password through his or her terminal 20 .

Thereafter, the electoral list server 40, upon receiving the first encryption key, generates a first ID (ID) for the voter account, and an authentication information storage step of registering the first encryption key and the first ID as authentication information (S22) and performs a first ID transmission step (S23) of transmitting the first ID information to the voter account.

As a result, the electoral list server 40 stores the first ID and the first encryption key information as authentication information for the voters. Thereafter, the electoral list server 40 or the electoral list server 40 and a separate voting right server 50 physically independent from the voter account requests the setting of the second encryption key different from the first encryption key from the voter account, and the voting right server 50 receives the first ID and the second encryption key from the voter account and performs a voting right storage step (S24) of storing the voting right for the voter account.

That is, at this time, since the second encryption key is managed completely separated from the electoral list server 40, only the voter himself/herself can know, and the security of the voter's authentication information is automatically secured.

In this environment, in order to receive the authentication information for the voter account in step S30 and determine that the voting right is effectively issued to the voter account, the computing device, when receiving the ID and password information from the voter account, the voting rights server 50 ), if the ID and password information received from the voter account are the same as the first ID and the second encryption key, it will be determined that the voting right is validly issued to the voter account.

That is, the electoral list server 40, which actually manages the electoral register, cannot access any information in the election process for the voter account, including whether the voter is authenticated, so that the confidentiality of the election can be completely maintained. .

On the other hand, in the present invention, through the above-mentioned first ID given to the voter through the electoral list server 30 at the time of an election in the present invention, in order to ensure confidentiality more firmly by making it impossible for the voter to know who voted, FIGS. 4 and 8 It may further include the technical features shown in.

Referring to the above-mentioned drawings, in performing the voting data receiving step (S30), the computing device receives (1.) an exchange request for voting rights in order to perform a vote from the voter's terminal 20, it The exchange request is transmitted to the server 40 and the intermediate server 60 completely physically independent from the voting rights server 50 .

At this time, the computing device or the intermediary server 60 converts the first ID and the second encryption key of the voter account into a second ID other than the first ID by the intermediary server independent of the electoral list server to generate encrypted voter account information. performing the voting right encryption step (S31, 2. 3. 4. 5. 6. of FIG. 8). In this case, the encrypted voter account information may be, for example, the second ID itself.

Thereafter, the encrypted voter account information, the first ID, and the second encryption key information are stored in the voting right server, and the encrypted voting right storage step (S32) of initializing the data of the intermediary server is performed. Initializing the data of the intermediary server in step S32 may be replaced by the concept of operating the intermediary server 60 managed by an exclusive person with a plurality of intermediary terminals 61 as shown in FIG. 5 . In this case, even if a record is left on a specific server, the voter cannot be specified.

In this case, the ballot count processing step (S50) derives a first ID corresponding to the encrypted voter account through a voting right server connected for voting in grouping voting information by voter account, and voting information for each first ID group to enable accurate vote counting.
