The NFT generator 112 receives the first vehicle identification number for the first bicycle held by the first member from the first client terminal 140 held by the first member, which is one of the plurality of members When a VIN (Vehicle Identification Number) is received and an order to request issuance of an NFT for the first bicycle is received, authentication is performed on the first client terminal 140 and at the same time includes the first vehicle identification number. , generate a first NFT containing the first member information of the first member as owner information.

When the first NFT is created, the registration processing unit 113 completes issuance of the first NFT by registering the first NFT in the preset blockchain network 10 for NFT registration.

When the issuance of the first NFT is completed, the issuance completion message transmission unit 114 generates an issuance completion message indicating that the first NFT has been issued and transmits it to the first client terminal 140.

After the issuance completion message is generated and transmitted to the first client terminal 140, the owner confirmation unit 115 receives information from the second client terminal 150 held by a second member, which is one of the plurality of members. , When the first vehicle identification number is received and a search request command for owner information of the first NFT is received, based on the first vehicle identification number, the first NFT registered in the blockchain network 10 After checking and confirming the first member information included in the first NFT, the first member information is transmitted to the second client terminal 150.

In relation to this, the operations of the NFT creation unit 112, the registration processing unit 113, the issuance completion message transmission unit 114, and the owner confirmation unit 115 will be described in detail below as an example.

First, a bicycle management platform server ( Assume that in 110), 'F10136584' is received as the first vehicle identification number for the first bicycle owned by 'Member 1', and a command to request the issuance of an NFT for the first bicycle is received.

Then, after the NFT generation unit 112 authenticates the first client terminal 140, it includes the first vehicle identification number 'F10136584' and at the same time, the member information storage unit 111 as shown in Table 1 above. ) You can create the first NFT containing 'Member Information 1 (Hong Gil-dong/1985.09.01/010-1111-2222/1 Uisadong-daero, Yeongdeungpo-gu, Seoul)' of 'Member 1' stored in ) as owner information.

In this way, when the first NFT is generated by the NFT generation unit 112, the registration processing unit 113 registers the first NFT in the preset blockchain network 10 for registration of the NFT, thereby processing the first NFT. Issuance of NFT can be completed.

At this time, according to an embodiment of the present invention, the registration processing unit 113 generates a transaction containing the first NFT in order to register the first NFT in the blockchain network 10, and then executes the transaction. It can be propagated to the blockchain network (10). Then, one of the plurality of first nodes 11, 12, 13, 14, 15, and 16 constituting the blockchain network 10 creates a block containing the transaction, It can be propagated to 1 nodes (11, 12, 13, 14, 15, 16). Accordingly, when the block is received by the plurality of first nodes (11, 12, 13, 14, 15, and 16), the plurality of first nodes (11, 12, 13, 14, 15, and 16) each Based on the previous block chained to the blockchain data stored in the node, the first NFT can be shared by chaining the block to the blockchain data.

In this way, when the issuance of the first NFT is completed by the registration processing unit 113, the issuance completion message transmission unit 114 generates an issuance completion message indicating that the first NFT has been issued to the first client terminal ( 140).

At this time, when the first client terminal 140 receives the publication completion message from the bicycle management platform server 110, the first client terminal 140 may output the publication completion message as text on the screen. Through this, 'Member 1' can easily check whether the first NFT has been issued.

In this way, after the publication completion message is generated by the publication completion message transmission unit 114 and transmitted to the first client terminal 140, the plurality of members 'member 1, member 2, member 3, ...' As the first vehicle identification number 'F10136584' is received from the second client terminal 150 held by 'Member 2', which is the second member of one of the two, to the bicycle management platform server 110, the first NFT Assume that a search request command for owner information of is received.

Then, the owner confirmation unit 115 searches the first NFT registered in the blockchain network 10 based on the first vehicle identification number 'F10136584' and identifies the 'member' included in the first NFT. After checking ‘Information 1 (Hong Gil-dong/1985.09.01/010-1111-2222/1 Uisadong-daero, Yeongdeungpo-gu, Seoul)’, ‘Member Information 1 (Hong Gil-dong/1985.09.01/010-1111-2222/1 Uisadong-daero, Yeongdeungpo-gu, Seoul)’ Can be transmitted to the second client terminal 150.

At this time, when the second client terminal 140 receives ‘member information 1 (Hong Gil-dong/1985.09.01/010-1111-2222/1 Uisadong-daero, Yeongdeungpo-gu, Seoul)’ from the bicycle management platform server 110, ‘member information 1’ (Hong Gil-dong/1985.09.01/010-1111-2222/1 Uisadong-daero, Yeongdeungpo-gu, Seoul)' can be printed as text on the screen. Through this, 'Member 1' can easily determine the owner information of the first NFT.

At this time, according to an embodiment of the present invention, the NFT generator 112 is an authentication configuration to allow only authorized users to issue an NFT for their bicycle through the NFT issuance service, and stores the authentication number. unit 116, public key storage unit 117, authentication event generation unit 118, random number generation unit 119, electronic signature request unit 120, determination unit 121, and authentication completion unit 122. It can be included.

The authentication number storage unit 116 contains an authentication number of k (k is a natural number of 3 or more) digits pre-issued for each of the plurality of members (the authentication number of each of the plurality of members is stored in the client terminal of each member). (pre-stored) is stored.

For example, assuming k is '3', information may be stored in the authentication number storage unit 116 as shown in Table 2 below.

A 3-digit authentication number pre-issued for each of multiple members. member 1 348 member 2 708 member 3 827 ... ...

The public key storage unit 117 contains a public key corresponding to a private key pre-issued for each of the plurality of members (the private key of each of the plurality of members is pre-stored in the client terminal of each member). It is saved.

For example, the public key storage unit 117 may store a public key corresponding to a pre-issued private key for each of the plurality of members, as shown in Table 3 below.

For each of the plurality of members
Pre-issued private key public key member 1 private key 1 public key 1 member 2 private key 2 public key 2 member 3 private key 3 public key 3 ... ... ...

When the first vehicle identification number is received from the first client terminal 140 and the issuance request command is received, the authentication event generator 118 generates an authentication event to perform authentication for the first client terminal 140. generates

When the authentication event occurs, the random number generator 119 generates a k-digit random number.

When the random number is generated, the electronic signature request unit 120 transmits the random number to the first client terminal 140 and requests an electronic signature based on the random number.

At this time, the first client terminal 140 pre-stores the first authentication number pre-issued for the first member and the first private key pre-issued for the first member in the memory, and the bicycle management platform When the random number is received from the server 110 and an electronic signature request is received, a k-dimensional column vector having as components the numbers of each digit constituting the first authentication number stored in the memory, After generating a k-dimensional row vector with the numbers of each digit constituting the random number received from the bicycle management platform server 110 as components, and then calculating a matrix product between the column vector and the row vector, an operation matrix of size k x k is obtained. , calculate the first operation value x by performing a modulo operation with (k-1) as a divisor on the random number, and then calculate the first operation value A first serial number is generated by concatenating the components constituting the first serial number, and the first electronic signature value is generated by encrypting the first serial number with the first private key stored in the memory. The signature value can be transmitted to the bicycle management platform server 110.

When the first electronic signature value is received from the first client terminal 140, the determination unit 121 converts the numbers of each digit constituting the first authentication number stored in the authentication number storage unit 116 into components. After generating the k-dimensional column vector having the k-dimensional column vector and the k-dimensional row vector having as components the numbers of each digit constituting the random number, calculating the matrix product between the column vector and the row vector to obtain the operation matrix After calculating the first operation value x by generating and performing a modulo operation with (k-1) as a divisor on the random number, the (x+1)th first column in the operation matrix By concatenating the components constituting the vector, the first serial number is generated, and the first electronic signature value is decrypted with the first public key corresponding to the first private key stored in the public key storage unit 117. , After generating the decryption value, it is determined whether the decryption value is the same as the first serial number.

When the authentication completion unit 122 determines that the decryption value is the same as the first serial number, it completes authentication for the first client terminal 140.

In the following, the operations of the authentication event generation unit 118, the random number generation unit 119, the electronic signature request unit 120, the first client terminal 140, the determination unit 121, and the authentication completion unit 122 are described. An example will be described in detail.

First, as in the above-described example, 'k = 3', and the first vehicle identification number 'F10136584' is received from the first client terminal 140 to the bicycle management platform server 110, and the issuance request command Assume this has been received.

Then, the authentication event generator 118 may generate an authentication event to authenticate the first client terminal 140.

In this way, when the authentication event is generated by the authentication event generator 118, the random number generator 119 can generate '251' as a 3-digit random number.

In this way, when the random number is generated by the random number generator 119, the electronic signature request unit 120 transmits the random number '251' to the first client terminal 140, and the random number You can request an electronic signature based on '251'.

At this time, the first client terminal 140 has in its memory the first authentication number '348' pre-issued for 'Member 1', the first member, and 'Member 1', the first member. 'Private key 1', which is the first private key, may be pre-stored, and the first client terminal 140 receives the random number '251' from the bicycle management platform server 110, requesting an electronic signature. When received, a three-dimensional column vector ' ' and ', a three-dimensional row vector whose components are the numbers of each digit constituting the random number '251' received from the bicycle management platform server 110. ' can be created.

After that, the first client terminal 140 uses the column vector ' ' and the row vector ' ' By calculating the matrix product between You can create an operation matrix of size 3 x 3, such as '.

Then, the first client terminal 140 calculates the first operation value '1' by performing a modulo operation with '2' as a divisor on the random number '251', and then calculates the operation matrix person ' ', which is the '2'th first column vector in ' By concatenating the components constituting ', a first serial number is generated such as '152040', and the first serial number '152040' is converted to 'private key 1', which is the first private key stored on the memory. By encrypting with , the first electronic signature value can be generated.

Afterwards, the first client terminal 140 may transmit the first electronic signature value to the bicycle management platform server 110.

At this time, when the first electronic signature value is received from the first client terminal 140 to the bicycle management platform server 110, the determination unit 121 is stored in the authentication number storage unit 116 as shown in Table 2 above. '348', the three-dimensional column vector whose components are the numbers of each digit constituting '348', the first authentication number. ' and ', the three-dimensional row vector whose components are the numbers of each digit constituting the random number '251'. ' can be created.

After that, the determination unit 121 determines the column vector ' ' and the row vector ' By calculating the matrix product between ', the operation matrix ' ' can be created.

Then, the determination unit 121 calculates the first operation value '1' by performing a modulo operation with '2' as a divisor on the random number '251', and then calculates the operation matrix ' 'The '2'th first column vector in ' By concatenating the components constituting ', the first serial number can be generated as '152040', and the first electronic signature value is stored in the public key storage unit 117 as shown in Table 3. 1 By decrypting with 'public key 1', the first public key corresponding to the private key 'private key 1', a decryption value such as '152040' is generated, and then the decryption value '152040' is the first serial number. It can be determined whether it is the same as '152040'.

At this time, since the decryption value '152040' is the same as the first serial number '152040', the authentication completion unit 122 can complete authentication for the first client terminal 140.

According to one embodiment of the present invention, the owner confirmation unit 115 may include a table maintenance unit 123 and an information transmission unit 124.

The table maintenance unit 123 stores and maintains a masking location table in which preset masking location information corresponding to each of the n types of personal information is recorded.

Here, the masking location information corresponding to each of the n types of personal information refers to information indicating the location of a target string to perform masking processing with a preset masking symbol in a string representing each personal information.

For example, if n is '4' and the preset masking symbol is '*', the table maintenance unit 123 corresponds to each of the four types of preset personal information as shown in Table 4 below. A masking position table in which preset masking position information is recorded can be saved and maintained.

4 types of personal information Masking location information name Characters other than the first character in a string representing a name birth date Characters that correspond to numbers in a string representing the date of birth phone number Characters corresponding to numbers in a string representing a mobile phone number address Characters that correspond to numbers in a string representing an address

When the first member information included in the first NFT is confirmed, the information transmission unit 124 refers to the masking location table and each of the n types of personal information included in the first member information. In the string for, the target string according to the masking location information corresponding to each personal information is masked with the masking symbol, and then the masked first member information is transmitted to the second client terminal 150.

Hereinafter, the operation of the information transmission unit 124 will be described in detail using an example.

First, as in the above-mentioned example, 'member information 1 (Hong Gil-dong/1985.09.01/010-1111-2222/1 Uisadong-daero, Yeongdeungpo-gu, Seoul)' included in the first NFT is confirmed by the owner confirmation unit 115. Let's assume it has been done.

Then, the information transmission unit 124 refers to the masking location table as shown in Table 4 above and sends the information included in 'Member Information 1 (Hong Gil-dong/1985.09.01/010-1111-2222/1 Uisadang-ro, Yeongdeungpo-gu, Seoul)'. In the string for each of the four types of personal information, the target string according to the masking location information corresponding to each personal information can be masked with the masking symbol '*', as shown in Table 5 below.

The sales amount request unit 125 receives sales information about the first bicycle from the first client terminal 140 after the issuance of the first NFT is completed through the registration processing unit 113 in the sales information database 126. ), when a sales information registration request command requesting registration is received, a request is made to transmit sales price information for the sale of the first bicycle to the first client terminal 140.

When the sales registration processing unit 127 receives the first sales price information as the sales price information of the first bicycle from the first client terminal 140, the sales information database 126 stores the first member information and the first bicycle. 1. Sales registration for the first bicycle is processed by storing the vehicle identification number and the first sales price information for the first bicycle in correspondence with each other.

After the sales registration for the first bicycle is processed, the payment method request unit 128 receives the first bicycle from the third client terminal 160 owned by a third member, which is one of the plurality of members. When a purchase request command is received, a request is made to transmit payment method information for payment to the third client terminal 160.

At this time, according to one embodiment of the present invention, the payment method request unit 128 may include a confirmation unit 132 and a request unit 133.

When the purchase request command is received from the third client terminal 160, the confirmation unit 132 extracts the first member information and the first vehicle identification number from the sales information database 126, and then extracts the first vehicle identification number from the sales information database 126. Based on this, check the first NFT registered in the blockchain network 10 and check whether the owner information of the first NFT included in the first NFT matches the first member information. do.

When the request unit 133 confirms that the owner information of the first NFT included in the first NFT matches the first member information, the request unit 133 transmits the payment method information to the third client terminal 160. ask for it

When first payment method information is received from the third client terminal 160, the payment processing unit 129 processes payment for the amount according to the first sales amount information based on the first payment method information. do.

When payment processing for the amount according to the first sales amount information is completed, the transaction registration processing unit 130 extracts the third member information, which is the member information of the third member, from the member information storage unit 111, and then extracts the third member information, which is the member information of the third member. By creating a transaction containing ownership transfer information instructing to change the first member information included as owner information in the first NFT to the third member information, and registering the transaction in the blockchain network 10 , the first member information included in the first NFT registered in the blockchain network 10 is processed to be changed to the third member information.

When the transaction is registered in the blockchain network 10, the sales information deletion unit 131 stores the first member information, the first vehicle identification number, and the first bicycle stored in the sales information database 126. The first sales amount information is deleted.

Below, the operations of the sales amount request unit 125, sales registration processing unit 127, payment method request unit 128, payment processing unit 129, transaction registration processing unit 130, and sales information deletion unit 131 are given as examples. For example, it will be explained in detail.

First, as in the above-described example, after the issuance of the first NFT is completed through the registration processing unit 113, from the first client terminal 140 to the bicycle management platform server 110, for the first bicycle Assume that a sales information registration request command requesting to register sales information in the sales information database 126 is received.

Then, the sales amount request unit 125 may request the first client terminal 140 to transmit sales amount information for selling the first bicycle.

In response, when it is said that '275,000 won', which is the first sales price information, is received from the first client terminal 140 to the bicycle management platform server 110 as the sales price information of the first bicycle, the sales registration processing unit (127) is the first member information, 'Member Information 1 (Hong Gil-dong/1985.09.01/010-1111-2222/1 Uisadong-daero, Yeongdeungpo-gu, Seoul)', and the first vehicle identification number 'F10136584' in the sales information database 126. ' and '275,000 won', which is the first sales amount information for the first bicycle, are stored in correspondence with each other, so that sales registration for the first bicycle can be processed.

In this way, after the sales registration for the first bicycle is processed by the sales registration processing unit 127, the third member of any one of the plurality of members 'member 1, member 2, member 3,...' Assume that a purchase request command for the first bicycle is received from the third client terminal 160 owned by 'Member 3' to the bicycle management platform server 110.

Then, the confirmation unit 132 included in the payment method request unit 128 receives the first member information, 'Member Information 1 (Hong Gil-dong/1985.09.01/010-1111-2222/Yeongdeungpo-gu, Seoul) from the sales information database 126.
