In this situation, the storage request unit 111 is sent from the first electronic terminal 151 of the first member 141, which is any one of a plurality of members subscribed to the NFT (Non-Fungible Token) issuance and transaction service. , When a request for issuing an NFT for the first multimedia content is received while the first multimedia content and the pre-produced first trial version content for the first multimedia content are received, a pre-set cloud server (160) for data storage ) and requests to store the first multimedia content and the first trial version content while transmitting the first multimedia content and the first trial version content to the cloud server 160 .

As the first multimedia content and the first trial version content are stored in the cloud server 160, the NFT generator 112 provides information about a first storage path where the first multimedia content is stored, from the cloud server 160. And, when information about the second storage path where the first trial content is stored is received, a first NFT including owner information indicating that the owner of the first multimedia content is the first member 141 is generated. Here, the storage path means a URI (Uniform Resource Identifier) on the cloud server 160 where data is stored.

When the first NFT is generated by the NFT generator 112, the message transmission unit 113 registers the first NFT in the blockchain network 100 pre-set for registration of the NFT, thereby processing the first NFT. After completion of issuance, an issuance completion message indicating that the first NFT has been issued is generated and transmitted to the first electronic terminal 151 .

After the issuance completion message is transmitted to the first electronic terminal 151 by the message transmission unit 113, the sales amount requesting unit 114 receives sales information on the first NFT from the first electronic terminal 151. When a sales registration request requesting to register in the sales information database 130 is received, the first electronic terminal 151 is requested to transmit sales amount information for the sale of the first NFT.

When the first sales amount information is received as the sales amount information of the first NFT from the first electronic terminal 151, the sales registration processing unit 115 stores the first sales information database 130 with respect to the first NFT. By storing sales amount information, sales registration for the first NFT is processed.

The trial version information confirmation unit 116 receives the first NFT from the second electronic terminal 152 of the second member 142, which is one of the plurality of members, after sales registration for the first NFT is processed. When a request for provision of trial content for purchase of is received, the first NFT registered in the blockchain network 100 is inquired and information on the second storage path included in the first NFT is checked. .

When the information on the second storage path is confirmed by the trial version information checker 116, the trial version content transmission unit 117 accesses the cloud server 160 based on the information on the second storage path, After receiving the first trial version contents, the first trial version contents are transmitted to the second electronic terminal 152 .

Hereinafter, storage request unit 111, NFT generator 112, message transmission unit 113, sales amount request unit 114, sales registration processing unit 115, trial version information confirmation unit 116, and trial version content transmission The operation of the unit 117 will be described in detail by way of example.

First, in the service providing server 110, from the first electronic terminal 151 of 'member 1 141', which is any one of the plurality of members subscribed to the NFT issuance and transaction service, 'multimedia content 1' And, suppose that a request for issuing an NFT for 'multimedia content 1' is received while pre-produced 'trial version content 1' for 'multimedia content 1' is received.

Then, the storage request unit 111 connects to the pre-set cloud server 160 for data storage and transmits 'multimedia content 1' and 'trial version content 1' to the cloud server 160, while 'multimedia content 1' and 'trial version content 1' may be requested to be stored.

As a result, as 'multimedia content 1' and 'trial version content 1' are stored in the cloud server 160, the 'storage path 1' in which 'multimedia content 1' is stored is stored in the service providing server 110 from the cloud server 160. ' and information on 'storage path 2' where 'trial version content 1' is stored, the NFT generator 112 indicates that the owner of 'multimedia content 1' is 'member 1'. 'NFT 1' with information can be created.

Then, the message transmitter 113 may complete the issuance of 'NFT 1' by registering 'NFT 1' in the blockchain network 100 pre-set for NFT registration.

At this time, according to one embodiment of the present invention, the message transmission unit 113 generates a transaction including 'NFT 1' in order to register 'NFT 1' in the blockchain network 100, and then the transaction can be propagated to the blockchain network 100.

Then, any one of the plurality of nodes 101, 102, 103, 104, 105, and 106 constituting the blockchain network 100 generates a block including the transaction, and the plurality of nodes ( 101, 102, 103, 104, 105, 106).

Accordingly, when the block is received by the plurality of nodes 101, 102, 103, 104, 105, and 106, the plurality of nodes 101, 102, 103, 104, 105, and 106 are stored in each node 'NFT 1' can be shared by chaining the block to the blockchain data based on the previous block chained to the existing blockchain data.

In this way, when issuance of 'NFT 1' is completed, the message transmission unit 113 may generate an issuance completion message indicating that 'NFT 1' issuance has been completed and transmit it to the first electronic terminal 151.

After that, when it is assumed that the service providing server 110 receives a sales registration request requesting the first electronic terminal 151 to register the sales information for 'NFT 1' in the sales information database 130, the sale The price requesting unit 114 may request the first electronic terminal 151 to transmit sales price information for the sale of 'NFT 1'.

Correspondingly, when it is assumed that the first sales amount information '100,000 won' is received as the sales amount information of 'NFT 1' from the first electronic terminal 151 in the service providing server 110, the sales registration processing unit ( 115) may process sales registration for 'NFT 1' by storing '100,000 won', which is the first sales price information for 'NFT 1', in the sales information database 130.

Thereafter, a request for provision of trial content for the purchase of 'NFT 1' is sent to the service providing server 110 from the second electronic terminal 152 of 'Member 2 (142)', one of the plurality of members. If it is said that it has been received, the trial version information confirmation unit 116 can search for 'NFT 1' registered in the blockchain network 100 to check information on 'storage path 2' included in 'NFT 1'. there is.

At this time, since the information on the 'storage path 2' is information on the path where the 'trial version content 1' is stored, the trial version content transmission unit 117 based on the information on the 'storage path 2', the cloud server 160 After accessing and receiving 'trial version contents 1', 'trial version contents 1' may be transmitted to the second electronic terminal 152 .

According to one embodiment of the present invention, the service providing server 110 may further include a payment means requesting unit 118, a payment processing unit 119, and a transaction registration processing unit 120.

After the first trial version content is transmitted to the second electronic terminal 152 by the trial version content transmission unit 117, the payment method requesting unit 118 receives information about the first NFT from the second electronic terminal 152. When the purchase request is received, a request is made to transmit payment method information for payment to the second electronic terminal 152 .

For example, as in the foregoing example, it is assumed that 'trial version content 1' is transmitted to the second electronic terminal 152 by the trial version content transmission unit 117, and thereafter, the service providing server 110 sends the second electronic terminal ( 152), when a purchase request for 'NFT 1' is received, the payment method requesting unit 118 may request the second electronic terminal 152 to transmit payment method information for payment.

Correspondingly, when the service providing server 110 receives the first payment method information from the second electronic terminal 152, the payment processing unit 119 performs identity authentication on the second member 142, and then the Based on the first payment method information, payment for the amount according to the first sales amount information is processed.

At this time, according to one embodiment of the present invention, the payment processing unit 119 is a specific configuration for performing identity authentication for the second member 142, a mobile phone number storage unit 121, an authentication event generating unit 122 , a first polynomial generator 123, a second polynomial generator 124, a verification code generator 125, a feedback request unit 126, and an authentication completion unit 127.

The mobile phone number storage unit 121 stores pre-designated mobile phone numbers of each of the plurality of members.

For example, the mobile phone number storage unit 121 may store pre-designated mobile phone numbers of each of the plurality of members as shown in Table 1 below.

multiple members phone number Member 1 (141) 010-1234-5678 Member 2 (142) 010-0123-4567 member 3 010-0111-1234 ... ...

When the first payment method information is received from the second electronic terminal 152 , the authentication event generation unit 122 generates an authentication event for self-authentication of the second member 142 .

When the authentication event is generated by the authentication event generator 122, the first polynomial generator 123 randomly generates a one-time authentication number of k digits (k is a natural number equal to or greater than 2), and then the highest degree is k. By designating each coefficient of the binary polynomial of -1 as a result value when a modulo-2 operation is performed on each of the k numbers constituting the one-time authentication number, the first polynomial is obtained. generate

Here, the modulo-2 operation means an operation of dividing a dividend by 2 and calculating a remainder thereto.

The second polynomial generation unit 124 generates a second polynomial by randomly designating each coefficient of a binary polynomial having a highest order of n (n is a natural number).

The verification code generation unit 125 multiplies the first polynomial and the second polynomial to generate an operation polynomial that is a binary polynomial whose highest order is k-1+n, and then converts each coefficient of the operation polynomial into a bit string. Generate a verification code of k + n bits with .

When the verification code is generated by the verification code generator 125, the feedback request unit 126 uses the mobile phone number of the second member 142 stored in the mobile phone number storage unit 121 as the receiver, While transmitting a text message including content instructing the second electronic terminal 152 to input the authentication number, and transmitting the second polynomial to the second electronic terminal 152, the one-time authentication number and Transmission of a feedback code generated based on the second polynomial is requested.

Hereinafter, operations of the authentication event generating unit 122, the first polynomial generating unit 123, the second polynomial generating unit 124, the verification code generating unit 125, and the feedback requesting unit 126 are exemplified, Let's explain in detail.

First, assume that the coefficient of each binary polynomial used in the present invention is a concept including the coefficient of the 0th order term.

In this situation, let k be '4' and n be '2', and as in the above example, the payment method requesting unit 118 transmits payment method information for payment to the second electronic terminal 152. Assume that a request is made, and in response to this, 'credit card information' is received from the second electronic terminal 152 to the service providing server 110 .

At this time, the authentication event generation unit 122 may generate an authentication event to perform identity authentication for 'member 2 (142)'.

Then, the first polynomial generation unit 123 randomly generates a one-time authentication number of '4' digits, such as '1230', and then converts each coefficient of a binary polynomial having a highest degree of '3' to the one-time authentication number. A first polynomial can be generated by specifying a result value when a modulo-2 operation is performed on each of '4' numbers constituting .

'과 같이 생성할 수 있다.In relation to this, '4' pieces constituting '1230', the one-time authentication number. The numbers are '1, 2, 3, 0', and the result value when the modulo-2 operation is performed on each of '1, 2, 3, 0' is '1, 0, 1, 0'. The 1-polynomial generation unit 123 sets the first polynomial to '1, 0, 1, 0' as each coefficient of the binary polynomial having the highest degree '3'.

' can be created.

'과 같이 생성할 수 있다.In addition, the second polynomial generation unit 124 randomly designates each coefficient of the binary polynomial having the highest degree '2', thereby generating the second polynomial '

' can be created.

'과 상기 제2 다항식인 '

'을 서로 곱하여 최고차수가 '5'가 되는 2진 다항식인 연산 다항식을 생성할 수 있다.Then, the verification code generation unit 125 is the first polynomial '

' and the second polynomial '

' can be multiplied with each other to generate an operational polynomial, which is a binary polynomial whose highest degree is '5'.

Here, when the verification code generator 125 generates the operation polynomial, since each coefficient of the operation polynomial must be subtracted as a binary value, the polynomial generated by multiplying the first polynomial and the second polynomial with each other For each coefficient, a result value obtained when a modulo-2 operation is performed may be calculated as each coefficient of the operation polynomial.

'과 같이 생성할 수 있다.Eventually, the verification code generator 125 converts the operation polynomial to '

' can be created.

Then, the verification code generation unit 125 generates a '6' bit verification code having '1, 0, 0, 0, 1, 0' as a bit string, each coefficient of the operation polynomial, as '100010'. can do.

'을 전송하면서, 상기 일회용 인증번호와 상기 제2 다항식을 기초로 생성되는 피드백 코드의 전송을 요청할 수 있다.Then, the feedback request unit 126 uses '010-0123-4567', the mobile phone number of 'Member 2 (142)' stored in the mobile phone number storage unit 121 as shown in Table 1 as a receiver, At the same time as sending a text message including content instructing the second electronic terminal 152 to input the authentication number '1230', to the second electronic terminal 152, the second polynomial '

While transmitting ', it is possible to request transmission of a feedback code generated based on the one-time authentication number and the second polynomial.

At this time, according to one embodiment of the present invention, after the second electronic terminal 152 receives a request for transmission of the second polynomial and the feedback code from the service providing server 110, the second member 142 , when the one-time authentication number is input to the second electronic terminal, each coefficient of a binary polynomial whose highest degree is k-1 is modulo-2 for each of the k numbers constituting the one-time authentication number. By specifying the result value when the operation is performed, the first polynomial is generated, and the operation polynomial, which is a binary polynomial whose highest degree is k-1+n by multiplying the first polynomial and the second polynomial with each other, is After generating, a first feedback code of k+n bits having each coefficient of the operation polynomial as a bit string may be generated and transmitted to the service providing server 110.

' while requesting transmission of a feedback code generated based on the one-time authentication number and the second polynomial, the second polynomial '' to the second electronic terminal 152.

' and the request for sending the feedback code has been received, and thereafter, 'Member 2 (142)' checks the text message and inputs '1230', the one-time authentication number, into the second electronic terminal 152. Let's assume.

'을 생성할 수 있다.Then, the second electronic terminal 152 converts each coefficient of the binary polynomial having the highest degree '3' into a modulo for each of '1, 2, 3, and 0' constituting '1230', which is the one-time authentication number. By specifying '1, 0, 1, 0', which is the result value when the -2 operation is performed, the first polynomial '

' can be created.

'과 상기 제2 다항식인 '

'을 서로 곱하여 최고차수가 '5'가 되는 2진 다항식인 상기 연산 다항식을 '

'과 같이 생성할 수 있다.In addition, the second electronic terminal 152 is the first polynomial '

' and the second polynomial '

The above operation polynomial, which is a binary polynomial whose highest degree is '5' by multiplying ' with each other, is '

' can be created.

Then, the second electronic terminal 152 converts the '6'-bit first feedback code having each coefficient '1, 0, 0, 0, 1, 0' of the operation polynomial as a bit string to '100010' and '100010'. It can be created together and transmitted to the service providing server 110.

In this way, in response to the transmission request of the feedback code, the first feedback code from the second electronic terminal 152 to the service providing server 110 (the first feedback code, in the second electronic terminal 152, is the highest Each coefficient of a binary polynomial of degree k-1 is designated as a result value when a modulo-2 operation is performed on each of the k numbers constituting the one-time authentication number, so that the first polynomial is After the first polynomial and the second polynomial are multiplied together, and a bit string composed of coefficients of the operation polynomial generated by multiplying each other) is received, the authentication completion unit 127 determines that the first feedback code is the verification code. , and if it is confirmed that the first feedback code matches the verification code, identity authentication for the second member 142 is completed.

For example, as in the above example, as the second electronic terminal 152 generates the first feedback code as '100010' and transmits it to the service providing server 110, the service providing server 110 transmits the second electronic terminal 152 to the second electronic terminal 152. Assume that the first feedback code '100010' is received from the terminal 152.

At this time, according to the above example, since the verification code generated by the verification code generation unit 125 is also '100010', the authentication completion unit 127 determines that the first feedback code '100010' is the verification code ' 100010', identity authentication for 'Member 2 (142)' can be completed.

Then, the payment processing unit 119 may normally proceed with payment processing for '100,000 won', which is the amount according to the first sales price information, based on the 'credit card information'.

In this way, when payment processing for the amount according to the first sales amount information is completed by the payment processing unit 119, the transaction registration processing unit 120 determines that the ownership of the first NFT is transferred from the first member 141 to the transaction registration unit 120. After generating a transaction including ownership transfer information indicating that it has been transferred to 2 members 142, and registering the transaction in the blockchain network 100, the first NFT registered in the blockchain network 100 Owner information included in is processed to be changed to the second member 142 .

For example, according to the above-described example, when it is assumed that the payment processing for '100,000 won', which is the amount according to the first sales amount information, is completed by the payment processing unit 119, the transaction registration processing unit 120 sends 'NFT 1 After generating a transaction containing ownership transfer information indicating that the ownership of 'Member 1 (141)' has been transferred to 'Member 2 (142)', and then registering the transaction in the blockchain network (100), Owner information included in 'NFT 1' registered in the blockchain network 100 can be processed to be changed to 'Member 2 (142)'.

In this regard, according to one embodiment of the present invention, the transaction registration processing unit 120 generates a transaction including the ownership transfer information in order to register the transaction in the blockchain network 100, and then the transaction can be propagated to the blockchain network 100.

Then, any one of the plurality of nodes 101, 102, 103, 104, 105, and 106 constituting the blockchain network 100 generates a block including the transaction, and the plurality of nodes ( 101, 102, 103, 104, 105, 106).
