1 is a conceptual diagram of a preferred embodiment for explaining an electronic voting system using a smart contract-based block chain according to the present invention, and Figures 2 and 3 are a preferred embodiment for confirming the election process according to the present invention. This is a flow chart for explanation.

Referring to FIG. 1, an electronic voting system using a smart contract-based blockchain according to the present invention includes a service provider management server 100 and a voter smartphone 400 connected to a wired/wireless communication network 200 such as the Internet.

Here, the election management server 100 is connected to the wired/wireless communication network 200 through a communication unit (not shown) to communicate with a plurality of smart phones 400. The election management server 100 further includes a database 110, an SMS processing unit 130, a web server 140, and a server 150.

Here, the server 150 has a control unit 151 and a processing unit 153. The processing unit 153 blocks the transaction 153 b generated by the smart contract 153 a.

Here, the election management server 100 is manufactured by Microsoft Corporation WINDOWS 2000, WINDOWS 2008, WINDOWS NT 3.51, WINDOWS NT 4.0, MacOS manufactured by an Apple computer of Cupertino, California, Java, UNIX (UNIX ) Or under the control of a variety of operating systems, including but not limited to Linux.

Here, the database 110 may be configured as a separate database server for each type and type.

The database 110 is, for example, a relational database management system (RDBMS) such as Oracle, Infomix, Sybase, and DB2, or object-oriented such as Gemston, Orion, O2, etc. It can be implemented according to the purpose of the present invention using a database management system (OODBMS), and can have appropriate fields to achieve its own function.

Here, the SMS processing unit 130 of the election management server 100 performs a message service program.

Here, the service program includes a generation module, a registration module, and a control module (not shown) as product data information, and in the service program, based on the election inquiry request information, the service program is unique, including an interbase with URL / special characters or numbers / special functions. It generates identification code information including digital election authentication public key (serial number, PIN number, etc.), a verification method that guarantees transparency and reliability based on a code system, a blockchain.

Here, the transaction 153 b generated by the smart contract 153 a corresponding to the number of the requested election authentication public key and product information 1:1 is blocked in the server 700 and stored 700.

Here, when the user's smartphone 400 touches the display area of the service request information, the information is written on an interface including a special character or number including a URL corresponding to the related information, or a special function.

In addition, the database 110 stores and manages the member information of the providers 117 and the voters 115. Member information may include the voter's (member) account ID, information for identification, password, phone number, member name, date of birth, address, email account, SNS information, service provision information, and the like.

Election type information database 113 is information by election type such as school, apartment, village, cooperative, shareholders' meeting, poll area information, election list ID number, ballot box block chain address, number of issued voting rights, voting end date, etc. (111) includes objective data information with a multi-authentication system such as voter account ID, delegation of choices, various types of questions, one vote per person, and stake ratio table for one person, and the transaction generated on the basis of the smart contract (153 a) (Transaction)(153 b) Information is also included.

Here, a separate identity register (not shown) is provided to simplify digital authentication in various services, thereby enabling accurate identification.

Here, the smartphone 400 is configured to include an input unit, a communication unit, a storage unit, and a processor (not shown) capable of executing a service.

An election authentication public key to which a serial number, a PIN number, etc. are assigned; When the election authentication public key is read from the identification code transmitted to the smartphone, the smartphone 400 provides a user interface environment by automatically executing an electronic voting app; And a server 100 communicating 200 with the smartphone 400.

Here, the server 100 performs an election authentication program, and the electronic voting program receives an election certificate issuance request from a voter, and generates election authentication public keys having a serial number, PIN number, etc. according to the requested voter (211) And, the generated election authentication public key is given to each voter (212), and the generated election authentication public key and voter information are 1:1 matched to the server based on the SCORE (213) and shared. The transaction 153 b generated by the smart contract 153 a is converted into a block chain 700 so that it is stored in the server 100 (100 a, 100 b, 100 c, 100 d ....).

Here, anonymity must be guaranteed by separating voter information and voting results so that they do not match.

Here, in the blockchain 700, the consensus structure is the core of the core. Here, the consensus structure can be roughly divided into two. One is a consensus structure that works when deciding what information to store in a block during block creation.

Second, the code of the blockchain itself, that is, a consensus structure related to modifying the logic and policy tasks applied to the blockchain is required.

Here, the smart contract 153a is a computer protocol for self-establishing, verifying, and executing a specific contract, which means that a transaction is automatically executed without intermediary intervention when certain conditions are satisfied.

That is, as an automated contract system, it is widely used for ownership transfer, inheritance, gift, and purchase of goods, and is recently used in connection with the Internet of Things. In smart contracts, transactions are automatically established according to conditions, so forgery and alteration damage by middle managers can be prevented.

In addition, since transaction information records are preserved, it is possible to prevent malicious actions such as forgery of contracts*?* manipulation of accident records, etc., thereby reducing credit risk and counterparty risk.

Here, the structure of the smart contract 153 a is simple. When the conditions of the contract made by the parties are satisfied, it is executed, and these transaction terms can be recorded in a script in the blockchain, which is also shared with all participants.

Here, if you apply a smart contract to voting, you can also set conditions for the election. And when the voting period is over, the voting is automatically closed and you can see the results of the ballot immediately. These functions can be used in a variety of ways, including amendments to laws and systems. If this function is applied to the voting system, the policy can be revised in real time at a desired time once the policy is determined.

In addition, if it is burdensome to build a system according to the purpose of voting and to build a system as desired, such as named voting and anonymous voting, and if it is burdensome to influence the result as the voting result is disclosed in real time, the result is determined according to the end time as needed. Can be disclosed.

Here, a transaction (153 b) is a collection of operations that make up one logical unit of work, and atomicity (one inseparable unit that completes or cancels all operations), consistency ( All data used is consistent), Isolation (Data accessed from other transactions can be viewed before and after the transaction is completed, but intermediate data in which the transaction is in progress can be viewed) None), Durability (when a transaction ends normally, the result is permanently applied to the system).

Here, it receives the inquiry request 214 of the election certification public key given to each voter, generates voter information related to the searched election certification public key, and responds to the request and generates an election (school, apartment, village). , Cooperatives, shareholders' meetings, public opinion polls, etc.) If you check and select the relevant information 215, a block is generated by collecting transactions 153 b generated based on the smart contract 153 a.

Here, the unique identification information of the smartphone 400 is a mobile identification number (hereinafter referred to as MIN or Mobile Subscription Identification Number, hereinafter referred to as MSIN), which can identify the user's smartphone 400, and international mobile device identification information (International Mobile Station). Equipment Identity (hereinafter referred to as IMEI), mobile communication number information, owner information, language identification information for each country, and information capable of identifying an electronic device are included.

In addition, the election authentication information is output on the basis of a smart contract (153a) on the basis of at least one of election classification information and regional information by type such as school, apartment, village, cooperative, shareholders' meeting, public opinion poll, etc. 153 b) Block chained 700 information.

In addition, by providing an identification code including a digital election authentication public key (serial number, PIN number, etc.), which is a means of verification that ensures transparency and reliability, the election authentication public key is requested according to the execution of the information data of the node including the election history. In order to transparently and accurately check the generated transaction related information, contracted information data based on election information may be included.

Here, by separating the digital election authentication public key into function and purpose (700, 700 a, 700 b, 700 c...), accurate identity verification and damage caused by identity theft are reduced, and certain conditions are set using a timestamp and hash function. If satisfied, the transaction is automatically executed to prevent malicious behavior such as forgery*?*manipulation of records, and anonymity is guaranteed.

In addition, since the election management server has the public key generation and basic information, electronic voting is possible without causing a transaction (153 b) in the blockchain system.

As such, the online voting system can overcome the spatial and temporal limitations of the existing voting method. Even if the voter does not go to the polling place, he or she can select 323 their vote (the candidate they support) using online media such as a computer or a smartphone 400. Voting time is drastically reduced because you only need to click on the voting method.

In addition, improved convenience and accessibility can increase the likelihood of voting participation for voters, elderly, disabled, and traveling voters who cannot directly visit polling places due to busy schedules. This convenience can contribute to improving the overall turnout.

And it can improve accuracy and speed in the voting and counting process. In the end, it is possible to save budget by shortening the manpower and time spent on election management.

In addition, there is no need to manually check the ballot paper by hand, and since it is automatically performed in the voting system, it is possible to quickly and prevent mistakes. When all voting is over, voters can use their voting confirmation number to display their own It is possible to check 410 whether the voting has been properly reflected.

By providing a related interface included in different types of related information, etc., through a processor that can be executed in response to each user's PC or smartphone, the authority to set the information included in the election authentication information and the election to be executed (school, apartment, village, cooperative, Shareholders' meetings, public opinion polls, etc.)In real time, a transaction (153 b) is created based on a smart contract (153 a), and it is blockchained by function and purpose (700, 700 a, 700 b, 700 c... ) And stored to prevent access through the duplicate identification code so that illegal elections (schools, apartments, villages, cooperatives, general shareholders' meetings, public opinion polls, etc.) can be eradicated further (343).

As a result, it is possible to track (216) malicious actions such as forgery*?* records manipulation, as a service that enables tracking related to authentication that links the system with election authentication using a blockchain.

And based on the smart contract (153a), the actual election (school, apartment, village, cooperative, etc.) by discriminating objective data information through a multi-authentication system such as delegation of choices, various types of questions, one vote for one person, and a table of stakes for one person. Anonymity can be guaranteed by creating a transaction (153 b) for each type and type to check whether it is a general shareholders' meeting, a public opinion poll, etc.).

In other words, one records a transaction (153 b) to confirm whether a voter is registered and whether or not to vote, and the other is a transaction by type and type (700, 700 a, 700 b, 700 c...) that contains the content of the vote. When creating (153 b), the anonymity of voters can be guaranteed.

In this case, the information that can identify the voter is deleted and stored in an encrypted format in the blockchain, encrypted and stored until the end of the online voting deadline, and stored on the server.

After the voting deadline is over, the voting is verified after certification of qualifications for counting votes. When the verification is completed, the encrypted voting result is decrypted again using the administrator's key and the result is aggregated (221).

As an electronic election using blockchain (schools, apartments, villages, cooperatives, shareholders' meetings, public opinion polls, etc.), as soon as the voting ends, a transaction (153 b) is created based on a smart contract (153 b) to be blockchained. By providing the transaction history (700, 700 a, 700 b, 700 c...), transparent and safe revision of the law and necessary related agendas are recorded and stored on the blockchain (700, 700 a, 700 b, 700 Electronic management such as c...) can be automatically implemented (222).

In addition, if the vote counting result by type and type is used in real time for voting or counting and applied to the policy (222), the election management work can be more efficient.

Here, when a specific value is generated, a block-chained transaction (153 b) is configured to perform a specific operation (a pre-designated computing task such as voting, polling, SMS, call, etc.) 323.

In addition, in the blockchain-based online voting system, the voting value is connected to blocks of different voting values using a hash function. Therefore, it is impossible to arbitrarily correct or omit it. A hash function is a kind of computer encryption technology, and is an algorithm that converts an input value of an arbitrary length into an output value of a fixed length.

Here, the hash function is easy to calculate in one direction to obtain a hash value from data, but since inverse calculation is very difficult, the input value cannot be inferred or calculated in any way. That is, the connection of the blocks to the voting details is a structure in which the hash value of the previous block is included in the current block, and it is difficult to forgery and thus the voting can proceed transparently.

Also, since blockchain-based records are signed with a time stamp, manipulation after voting is impossible.

Here, by comparing and analyzing information on elections (schools, apartments, villages, cooperatives, general shareholders' meetings, public opinion polls, etc.), check the validity information of related elections (schools, apartments, villages, cooperatives, general shareholders' meetings, public opinion polls, etc.), and make transactions. If (Transaction) (153 b) does not match (343), it is judged as an illegal related malicious activity such as forgery*?* record manipulation, etc., and information that can be reported (216) is provided.

And even the same voter can access and verify mobile electronic election (school, apartment, village, cooperative, shareholders' meeting, public opinion poll, etc.) information only through the authentication public key that includes each unique identification information such as individual serial number and PIN number. And restrict access rights and methods for each public key so that access through duplicate identification codes can be eradicated and prevented.

Here, referring to FIG. 2, the election certification inquiry request of the election certification public key (serial number, PIN number, etc.) 700a on the Internet receives an election certification request from a voter and enters a serial number, PIN number, etc. according to the requested voter. The election authentication public keys possessed are generated (211) and the generated election authentication public keys are given to each voter (212).

Blockchain a transaction (153 b) created with a smart contract (153 a) so that the election authentication public key generated here and the voter information can be matched 1:1 to the server and shared based on the SCORE To be stored (700).

And when the inquiry request 214 of the election certification public key given to each voter is received, the voter information related to the searched election certification public key is generated, and when the generated voter identification code information is checked, the transaction created by the smart contract (153a) ( Transaction) (153 b) is blocked and transmitted to the voter 400, and then the voter can check or set the election (school, apartment, village, cooperative, general shareholders' meeting, public opinion poll, etc.) Provide (313).

Here, by providing an identification code including a digital election authentication public key, which is a means of verifying transparency and reliability, when requesting an inquiry for the election authentication public key, a transaction generated according to the execution of the information data of the node including the election history (153) b) It includes information data 215 contracted by issuing an election certificate based on election information so that related information can be transparently and accurately checked.

In addition, it is possible to check the election process by determining objective data information based on the smart contract 153a based on the voter's election certification public key and the voter election certification public key.

Here, by separating the digital election authentication public key by function and use (700, 700 a, 700 b, 700 c...), accurate identity verification and damage caused by identity theft are reduced, and a certain condition using a timestamp and hash function Is satisfied, the transaction is automatically executed.

And by providing a related interface included in different types of related information, etc., through a processor that can be executed in response to each user's PC or smartphone, the authority to set the information included in the election authentication information and the election to be executed (school, apartment, village, cooperative , Shareholders' meetings, public opinion polls, etc.)In real time, a transaction (153 b) is created based on a smart contract (153 a), and it is blockchained by function, type, and purpose (700, 700 a, 700 b, 700 c). ...) and save (100, 100 a, 100 b, 100 c...).

In addition, although the existing block chain-based election authentication is at the level of serial number verification, the actual election by discriminating objective data information through a multi-authentication system such as delegation of choices based on smart contracts, various types of questions, 1 person 1 vote, and 1 person stake rate table. (School, apartment, village, cooperative, shareholders' meeting, public opinion poll, etc.) by creating a transaction (153 b) by type and type (700, 700 a, 700 b, 700 c...) Provide last name.

As a result, immediately after the end of the electronic voting using the blockchain, a transaction (153 b) is created based on a smart contract (153 a) and a blockchain-based election (school, apartment, village, cooperative, shareholders' meeting, public opinion poll) Etc.) By providing a history, the bill will be revised transparently and safely, and the results of the counting by type and type (700, 700 a, 700 b, 700 c...) will be reflected in the policy in real time and automatically applied (222). Make it possible.

Here, when a specific value is generated, a block-chained transaction 153 b) provides information to perform a specific operation (a pre-designated computing task such as voting, polling, SMS, call, etc.) 323.

And even the same voter can access and verify mobile electronic election (school, apartment, village, cooperative, shareholders' meeting, public opinion poll, etc.) information only through the authentication public key that includes each unique identification information such as individual serial number and PIN number. And restrict access rights and methods for each public key so that access through duplicate identification codes can be eradicated and prevented.

Here, by comparing and analyzing information on elections (schools, apartments, villages, cooperatives, general shareholders' meetings, public opinion polls, etc.), the validity information of related elections (schools, apartments, villages, cooperatives, general shareholders' meetings, public opinion polls, etc.) If the transaction 153 b does not match, it is possible to provide more information that can be judged and reported 216 as an illegal malicious act such as forgery*?* record manipulation.

Here, the voter smartphone 400 using electronic voting includes a processor that executes a voter interface program for using electronic voting.

Here, when the election authentication public key is read from the identification code including the election authentication public key, the voter interface program requests an inquiry of the election authentication public key from the server, and also provides smartphone information to the server when the inquiry is requested, and provided from the server. A related information message in which the transaction generated on the basis of the smart contract for the authority included in the election authentication information and the election (computing work specified in advance such as schools, apartments, villages, cooperatives, shareholders' meetings, public opinion polls, etc.) is blockchained. Is displayed on the display so that the delegation of choices, various types of questions, amendments to the bill, and necessary related agendas can be reflected in the policy in real time through a table of various types of questions, one vote per person, and a stake ratio table.

As such, the online voting system has various additional functions compared to voting using existing ballots. It can improve the voter participation rate, speed up the counting, and reduce costs.
