1 is a diagram illustrating the structure of a content activation confirmation server that checks whether the content is content for which activation for copyright has been completed based on a two-dimensional code according to an embodiment of the present invention.

Referring to FIG. 1 , the content activation confirmation server 110 according to an embodiment of the present invention includes a content information database 111 , a genuine product authentication confirmation unit 112 , and a genuine product authentication confirmation message transmission unit 113 . .

First, the plurality of contents in the present invention are contents that are pre-designated that the activation of copyright has been completed. A primary identification number and a secondary identification number of k (k is a natural number greater than or equal to 2) digits are pre-allocated, and at the same time, the primary identification number and secondary identification number for each content are applied as inputs to a preset token generation function. It is assumed that an identification token as an output value is pre-allocated, and a two-dimensional code including a main identification number for each content and information on an identification token is pre-inserted into each of the plurality of contents.

Here, the content means digital multimedia content such as video content, music content, webtoon content, image content, and the like.

In addition, the two-dimensional code means a code capable of inserting information such as various characters on a two-dimensional image pattern, and a QR code (Quick Response Code), veri code, dot code, etc. are used, A digital code or the like capable of expressing predetermined data on a two-dimensional image through a pixel space composed of a plurality of dots disclosed in Korean Patent No. 10-1897960 may be used. In this regard, the illustrated figure of FIG. 2 shows that the digital code 211 capable of expressing predetermined data on a two-dimensional image through a pixel space composed of a plurality of yellow dots on the surface of the content 210 is the two-dimensional code. An example in which it is inserted is shown. As shown in reference numeral 211, this digital code is composed of yellow dots, so when contrasted with a white background, the color contrast is not clear, so it is difficult to clearly observe with the naked eye, but the electronic terminal In that the camera can perform the identification of the yellow dot differently from the human eye, the pattern of the yellow dot can be clearly identified through the electronic terminal.

In this situation, in the content information database 111 of the content activation confirmation server 110, an auxiliary identification number for each of a plurality of contents pre-designated as having completed the activation of copyright and identification of each of the plurality of contents Tokens are stored in correspondence with each other.

At this time, according to an embodiment of the present invention, the token generation function is input when the n-digit main identification number and k-digit auxiliary identification number pre-allocated to any one of the plurality of contents are applied as inputs. Kronecker Product (Kronecker Product) between a row vector having n numbers constituting the n-digit main identification number applied as a component and a row vector having k numbers constituting the k-digit auxiliary identification number applied as input as components ) to generate an operation matrix having a size of 1 x nk, generate a data string composed of nk components constituting the operation matrix, and apply the data string as an input to a preset hash function. It may be a function that calculates a hash value as an identification token for any one of the contents.

Here, the Kronecker product refers to a matrix that specifically expresses the tensor product of two matrices, and when a matrix A having a size of a x b as in Equation 1 below and a matrix B having a size of p x q as in Equation 2 below are given. , the Kronecker product between the matrix A and the matrix B may be expressed as Equation 3 below.

For example, it is assumed that n is '3' and k is '4', and the plurality of contents are 'content 1, content 2, and content 3'.

At this time, for 'Content 1', it is assumed that '321' is pre-allocated as the main identification number of '3' digits, '1233' is pre-allocated as the secondary identification number of '4' digits, and '321' When '1233' and '1233' are applied as inputs to the token generation function and the calculated output value is 'identification token 1', 'content 1' includes information about '321' and 'identification token 1'. A two-dimensional code may be pre-inserted, and in the content information database 111, '1233', which is an auxiliary identification number for 'content 1', and 'identification token 1', which is an identification token for 'content 1', correspond to each other. may be stored.

In this way, in the content information database 111, as shown in Table 1 below, auxiliary identification numbers for each of 'Content 1, Content 2, and Content 3' and identification of each of 'Content 1, Content 2, and Content 3' Tokens may be stored in correspondence with each other.

contents secondary identification number identification token content 1 1233 identification token 1 content 2 2344 identification token 2 content 3 3455 identification token 3

In the state in which the user 150 who purchased the first content, which is any one of the plurality of contents, displays the first content on the screen through the first electronic terminal 160, As the user 150 scans and recognizes the two-dimensional code inserted in the first content displayed on the screen of the first electronic terminal 160 using the second electronic terminal 170, the second electronic As the first main identification number and the first identification token extracted from the two-dimensional code inserted into the first content are received from the terminal 170 , the first content from the second electronic terminal 170 is genuine for copyright When a confirmation request as to whether or not the authentication is completed content is received, based on the first main identification number and the first identification token received from the second electronic terminal 170, with reference to the content information database 111, It is checked whether the first content is content for which activation for copyright has been completed.

When it is confirmed that the first content is the content for which genuine product activation has been completed, the genuine product authentication confirmation message transmission unit 113 generates an activation confirmation message indicating that the first content is the content for which the genuine product activation has been completed to generate a second electronic terminal ( 170).

Hereinafter, the operations of the genuine product authentication confirmation unit 112 and the genuine product authentication confirmation message transmission unit 113 will be described in detail, for example.

First, as in the above-described example, the plurality of contents are referred to as 'Content 1, Content 2, and Content 3', and the user 150 who purchases 'Content 1' receives 'Content 1' through the first electronic terminal 160 . ' is referred to as a state displayed on the screen, and at this time, the user 150 uses a camera mounted on the second electronic terminal 170 to display 'content 1' on the screen of the first electronic terminal 160 . Assume that the 2D code inserted in 'Content 1' is recognized by scanning the 2D code inserted in .

In this case, according to the above-described example, since '321' and 'identification token 1' are included in the two-dimensional code inserted into 'Content 1', the second electronic terminal 170 is a two-dimensional code inserted into 'Content 1'. While extracting '321' and 'identification token 1' from the code and transmitting it to the content activation confirmation server 110, a confirmation request for whether 'content 1' is the content whose copyright has been activated is confirmed for content activation It can be transmitted to the server 110 .

In this way, while the user 150 who has purchased 'Content 1' displays 'Content 1' on the screen through the first electronic terminal 160 , the user 150 uses the second electronic terminal 170 . As the two-dimensional code inserted in 'Content 1' displayed on the screen of the first electronic terminal 160 is scanned and recognized, 2 inserted in 'Content 1' from the second electronic terminal 170 When the '321' and 'identification token 1' extracted from the dimension code are received, a confirmation request is received from the second electronic terminal 170 as to whether the 'content 1' is the content for which activation for copyright has been completed. The authentication confirmation unit 112 refers to the content information database 111 based on '321' and 'identification token 1' received from the second electronic terminal 170, and 'Content 1' is genuine authentication for copyright. It is possible to check whether this is the completed content.

At this time, according to an embodiment of the present invention, the genuine product authentication confirmation unit 112 is a specific configuration for performing confirmation of whether the first content is the content for which activation for copyright has been completed, and an auxiliary identification number extraction unit 114 , an operation result confirmation unit 115 , and a confirmation processing unit 116 may be included.

The auxiliary identification number extraction unit 114 scans the two-dimensional code inserted into the first content displayed on the screen of the first electronic terminal 160 by the user 150 using the second electronic terminal 170 . As the recognition is performed, the first main identification number and the first identification token extracted from the two-dimensional code inserted into the first content are received from the second electronic terminal 170, and the second electronic terminal 170 ), when a confirmation request is received as to whether the first content is the content for which activation for copyright has been completed, the same as the first identification token received from the second electronic terminal 170 from the content information database 111 The auxiliary identification number stored in correspondence with the identification token is extracted.

The operation result check unit 115 is an auxiliary identification number stored in correspondence with the same identification token as the first identification token received from the content information database 111 from the second electronic terminal 170, and the first auxiliary identification When the number is extracted, the first main identification number received to the second electronic terminal 170 and the first auxiliary identification number extracted from the content information database 111 are applied as inputs to the token generation function. It is checked whether the operation result matches the first identification token received from the second electronic terminal 170 .

When it is confirmed that the operation result matches the first identification token received from the second electronic terminal 170 , the confirmation processing unit 116 confirms that the first content is the content for which activation has been completed.

Hereinafter, operations of the auxiliary identification number extraction unit 114 , the operation result verification unit 115 , and the verification processing unit 116 will be described in detail, for example.

First, as in the above example, the second electronic terminal 170 extracts '321' and 'identification token 1' from the two-dimensional code inserted into 'content 1' and transmits it to the content activation confirmation server 110 In the meantime, as 'Content 1' transmits a confirmation request as to whether or not the content activation for copyright has been completed to the content activation confirmation server 110, the content activation server 110 identifies '321' and ' Assume that the confirmation request has been received, with token 1' being received.

Then, the auxiliary identification number extraction unit 114 can extract '1233', which is an auxiliary identification number stored in correspondence with the same identification token as 'identification token 1', from the content information database 111 as shown in Table 1 above. have.

Then, the calculation result check unit 115 may check whether the calculation result calculated when '321' and '1233' are applied as inputs to the token generation function matches the 'identification token 1'.

At this time, according to an embodiment of the present invention, the operation result check unit 115 applies '321' and '1233' to the token generation function as inputs, and then generates '3' numbers constituting '321' as components. '1 x 12' size by calculating the Kronecker product between '[3 2 1]', which is a row vector with Generates an operation matrix of '[3 2 1 6 4 2 9 6 3 9 6 3]', and a data stream consisting of '12' components constituting the operation matrix is created as '321642963963' After doing this, it is possible to check whether the calculated result of applying '321642963963' as an input to the preset hash function matches the 'identification token 1'.

In this regard, since both the operation result and the 'identification token 1' are output values calculated by applying '321' and '1233' to the token generation function as inputs, the operation result check unit 115 determines that the operation result is It can be confirmed that it matches 'identification token 1'.

Then, the confirmation processing unit 116 may confirm that 'Content 1' is the content for which activation is completed.

In this way, when the first content is confirmed by the genuine product authentication confirmation unit 112 as the content for which genuine product activation has been completed, the genuine product authentication confirmation message transmission unit 113 indicates that the first content is the genuine product certified content. An authentication confirmation message is generated and transmitted to the second electronic terminal 170 .

At this time, according to an embodiment of the present invention, when it is confirmed that the first content is the content for which genuine product activation has been completed by the genuine product authentication confirmation unit 112, the activation confirmation message transmitting unit 113 transmits the first content. A genuine activation confirmation message indicating that the content activation for copyright has been completed is generated and transmitted to the second electronic terminal 170, but the activation confirmation message is applied as an input to a pre-built speech synthesis model to perform speech synthesis By doing so, after generating the synthesized voice data for the activation confirmation message, it is possible to additionally transmit the synthesized voice data for the activation confirmation message to the second electronic terminal 170 .

For example, as in the above example, when it is confirmed that 'content 1' is the content for which genuine product activation has been completed by the genuine product authentication confirmation unit 112, the genuine product authentication confirmation message transmission unit 113 sends the 'content 1' to the copyright. By generating an activation confirmation message indicating that activation is completed for the content and transmitting it to the second electronic terminal 170, the activation confirmation message is applied as an input to a pre-built speech synthesis model to perform voice synthesis. , after generating the synthesized voice data for the activation confirmation message, the synthesized voice data for the activation confirmation message may be additionally transmitted to the second electronic terminal 170 .

At this time, according to an embodiment of the present invention, when the second electronic terminal 170 receives the activation confirmation message and synthetic voice data for the activation confirmation message from the content activation confirmation server 110, the authentication At the same time as outputting the confirmation message as text on the screen, the synthesized voice for the activation confirmation message may be output to the speaker based on the synthesized voice data for the activation confirmation message. Through this, the user 150 can confirm that the 'content 1' is the content for which the activation of the copyright has been completed.

According to an embodiment of the present invention, the content activation confirmation server 110 may further include a confirmation history information generating unit 117 and a registration requesting unit 118 .

The confirmation history information generating unit 117 receives the current location information of the second electronic terminal 170 from the second electronic terminal 170 when the activation confirmation message is transmitted to the second electronic terminal 170, and the After generating the time information for the current time when the activation confirmation message is transmitted to the second electronic terminal 170, the current location information, the time information, the first main identification number and the first auxiliary identification number Generates verification history information.

When the confirmation history information is generated, the registration request unit 118 generates a transaction including the confirmation history information, and then, among a plurality of node devices 11, 12, 13, 14 constituting the block chain network, Any one of the first node devices is randomly selected, and the transaction is transmitted to the first node device, while a registration request of the transaction to the blockchain network is transmitted.

Hereinafter, the operations of the confirmation history information generating unit 117 and the registration requesting unit 118 will be described in detail, for example.

First, as in the above-described example, as 'Content 1' is confirmed as content for which activation for copyright has been completed by the genuine product authentication confirmation unit 112, the 'content It is assumed that an activation confirmation message indicating that 1' is content for which activation has been completed is transmitted to the second electronic terminal 170 .

Then, the confirmation history information generating unit 117 may receive 'location information 1', which is the current location information of the second electronic terminal 170, from the second electronic terminal 170, and the activation confirmation message is the second Time information about the current time transmitted to the electronic terminal 170 may be generated like 'time information 1'.

Then, the confirmation history information generating unit 117 is '321', which is a main identification number for 'location information 1', 'time information 1', and 'content 1', and '1233' which is a secondary identification number for 'content 1'. Confirmation history information consisting of ' can be created.

Then, the registration request unit 118 generates a transaction including the confirmation history information, and then the first node that is any one of the plurality of node devices 11, 12, 13, 14 constituting the blockchain network. Devices can be randomly selected.

At this time, when the first node device is referred to as the node device 11, the registration request unit 118 may transmit the registration request to the blockchain network of the transaction while transmitting the transaction to the node device 11. have.

At this time, when the transaction and the registration request are received from the content activation confirmation server 110, the first node device connects the previous block chained to the block chain data stored in the memory of the first node device. Based on the basis, the first block including the transaction is created and the first block is chained to the block chain data to complete the storage of the first block, and then to the first block through the block chain network. One block is propagated to the remaining node devices except for the first node device among the plurality of node devices 11 , 12 , 13 , and 14 .

For example, as in the above example, the first node device is referred to as the node device 11 , and the registration request unit 118 transmits the transaction to the node device 11 , and the transaction is registered in the blockchain network. By sending a request, when the node device 11 is told that the transaction and the registration request have been received, the node device 11 is chained to the blockchain data stored in the memory of the node device 11 Based on the previous block, the first block including the transaction is created, and the first block is chained to the block chain data, thereby completing the storage of the first block, and then through the block chain network. The first block may be propagated to the remaining node devices 12 , 13 , and 14 except for the node device 11 among the plurality of node devices 11 , 12 , 13 , and 14 .

Specifically, when the transaction and the registration request are received from the content activation confirmation server 110, the node device 11 refers to the block header of a previous block connected to the block chain data in a chain and includes the transaction. The first block, which is a new block that has been created, may be generated. Then, the node device 11 connects the first block to the block chain data by chaining the first block to the other node devices ( 12, 13, 14).

In this way, the content activation confirmation server 110 according to the present invention generates the confirmation history information and registers it in the block chain network when the genuine authentication confirmation message is transmitted to the second electronic terminal 170, so that the content It can support the producer of the .
