In addition, the Kronecker product refers to a matrix that specifically expresses the tensor product of two matrices, and when a matrix M of m x n as in Equation 2 below and a matrix N of p x q as in Equation 3 below are given, the matrix The Kronecker product between M and the matrix N can be expressed as Equation 4 below.

In this regard, the token calculation unit 112 configures the first main identification number by applying '123', which is the first main identification number, and '456', which is the first auxiliary identification number, as inputs to the token generation function. ', which is a column vector with '123', which is the '3' number of

' and ', which is a row vector having '456', which is the '3' number constituting the first auxiliary identification number, as a component.

After generating an operation matrix having a size of '3 x 3' by calculating the Kronecker product between ', the Euclidean norm of the operation matrix may be calculated as the first authentication token.

In this way, when the first authentication token is calculated by the token calculating unit 112, the transaction generating unit 113 issues the first authentication token and the first auxiliary identification number '456' to the issuance history database 122 At the same time, it is possible to generate a transaction including the first data, the first authentication token, and the first auxiliary identification number '456'.

Specifically, when it is assumed that node device 1 (11) is randomly selected as the first node device, which is one of the plurality of node devices (11, 12, 13, 14), node device 1 (11) manages data. When the registration request is received along with the transaction from the server 110, the first block, which is a new block including the transaction, can be created by referring to the block header of a previous block connected to the block chain data. have. Then, the node device 1 (11) connects the first block to the block chain data in a chain, so that after the storage of the first block is completed, the first block is transferred to a plurality of nodes through the block chain network. Among the

devices

11 , 12 , 13 , and 14 , it may propagate to the remaining node devices except for node device 1 11 , and may generate the feedback message and transmit it to the data management server 110 .

In this way, when the feedback message indicating that the transaction has been registered in the block chain network is received from the node device 1 11 to the data management server 110, the transmitter 115 transmits the ' After generating a first code that is a two-dimensional code including data for 123' and the first authentication token, and inserting the first code into the first image to generate a code-embedded image, the code-embedded image It is possible to transmit the image file for the management terminal 150 .

Then, the souvenir maker may use the image file for the code-embedded image to print the code-embedded image on the wrapping paper or surface of the souvenir, thereby producing and selling the souvenir on which the code-embedded image is printed.

According to an embodiment of the present invention, the data management server 110 may further include an auxiliary identification number extraction unit 116 , a token verification unit 117 , a data search request unit 118 and a data transmission unit 119 . can

The auxiliary identification number extracting unit 116 receives the first code from the electronic terminal 160 as the first code is scanned and recognized in the electronic terminal 160 of the consumer who purchased the souvenir on which the code insertion image is printed. While the first main identification number and the first authentication token included in are received, when a data inquiry request based on the first main identification number and the first authentication token is received, the 1 Extract the auxiliary identification number stored in correspondence with the same authentication token as the authentication token.

The token confirmation unit 117 is an auxiliary identification number stored in correspondence with the same authentication token as the first authentication token from the issuance history database 122, and when the first auxiliary identification number is extracted, the electronic terminal 160 Whether the calculation result calculated when the first main identification number received from and the first auxiliary identification number extracted from the issuance history database 122 is applied as an input to the token generation function becomes the first authentication token check

When it is confirmed that the operation result is the first authentication token, the data search request unit 118 is a second node device that is any one of the plurality of

node devices

11, 12, 13, and 14, and the first A search request for the first data is transmitted while transmitting the auxiliary identification number and the first authentication token as an index value for searching the first data.

The data transmission unit 119 allows the second node device to use the first auxiliary identification number and the first authentication token as an index value to obtain the first auxiliary identification number and the first authentication token from the block chain data together with the first auxiliary identification number and the first authentication token. As the stored first data is searched, if the first data is received from the second node device as a search result, the first data is transmitted to the electronic terminal 160 .

Hereinafter, operations of the auxiliary identification number extraction unit 116 , the token verification unit 117 , the data search request unit 118 , and the data transmission unit 119 will be described in detail.

First, when the image file for the code-inserted image into which the first code is inserted is completed to be transmitted to the management terminal 150, the souvenir maker prints the code-embedded image on the souvenir to make a real souvenir, and then inserts the code Souvenirs with printed images can be sold. In this case, it is assumed that the consumer who purchased the souvenir scans and recognizes the first code inserted in the code embedded image using the consumer's electronic terminal 160 .

Then, the electronic terminal 160 may extract the first main identification number '123' and the first authentication token included in the first code and transmit it to the data management server 110 .

In this way, as the first code is scanned and recognized in the electronic terminal 160 of the consumer who purchased the souvenir on which the code insertion image is printed, the first code included in the first code is scanned from the electronic terminal 160 . When the first main identification number '123' and the first authentication token are received, the data management server 110 receives a data inquiry request based on the first main identification number '123' and the first authentication token, The auxiliary identification number extraction unit 116 may extract the auxiliary identification number stored in correspondence to the same authentication token as the first authentication token from the issuance history database 122 .

At this time, by the auxiliary identification number extraction unit 116, from the issuance history database 122, the first auxiliary identification number '456' as an auxiliary identification number stored in correspondence to the same authentication token as the first authentication token When it is said that the number has been extracted, the token confirmation unit 117 is the first auxiliary '123' received from the electronic terminal 160 and '456' extracted from the issuance history database 122, which is the first main identification number. It can be checked whether the calculation result calculated when the identification number is applied as an input to the token generating function becomes the first authentication token.

If it is confirmed that the operation result becomes the first authentication token, the first main identification number received from the electronic terminal 160 and the information extracted from the two-dimensional code from which the first authentication token is normally issued are correct means, the data search request unit 118 is the second node device that is any one of the plurality of

node devices
