The real product identification unit 115 allows the first user 135 who has purchased a first real product, which is any one of the plurality of real products, to display the first real product through the first electronic terminal 140 on the surface of the first real product. As the printed 2D code is scanned and recognized, when the first identification matrix extracted through the 2D code printed on the surface of the first real product is received from the first electronic terminal 140, the first identification matrix is received. Based on the identification matrix and the verification matrix, the serial number of the first real product is confirmed by checking an n-dimensional embedding vector corresponding to each digit constituting the serial number of the first real product, Based on the serial number of the first real product, whether the real product for which the first user 135 scanned the 2D code through the first electronic terminal 140 corresponds to which of the plurality of real products. By performing identification on , the first real product is identified as a real product scanned by the first user 135 among the plurality of real products.

At this time, according to one embodiment of the present invention, the real product identification unit 115 may include a batch matrix restoration unit 118, a serial number confirmation unit 119, and an identification processing unit 120.

When the first user 135 scans and recognizes the two-dimensional code printed on the surface of the first real product through the first electronic terminal 140, the disposition matrix restorer 118 generates the first electronic terminal 135. When the first identification matrix extracted through the two-dimensional code printed on the surface of the first physical product is received from (140), the first identification matrix is multiplied by an inverse matrix to the verification matrix, thereby generating a first identification matrix. Restore the batch matrix.

When the first array matrix is restored, the serial number checking unit 119 corresponds to the same embedding vector as each of the n row vectors constituting the first array matrix and stores a natural number from the embedding vector storage unit 111. By sequentially extracting and configuring n-digit serial numbers, the serial number of the first real product is confirmed.

When the serial number of the first real product is confirmed, the identification processing unit 120 determines the serial number corresponding to each real product stored in the serial number storage unit 112 for each of the plurality of real products, and the The serial number of the first real product is compared with each other, and a real product having a serial number matching the serial number of the first real product among the plurality of real products is the real product scanned by the first user 135. It is identified as the first physical product.

Hereinafter, operations of the disposition matrix restoration unit 118, the serial number verification unit 119, and the identification processing unit 120 will be described in detail by way of example.

First, as in the above example, when n is set to '3', a first user (135 ) scans and recognizes the two-dimensional code printed on the surface of 'real product 1' through the camera mounted on the first electronic terminal 140, and identification of 'real product 1' from the two-dimensional code Assume that the first identification matrix is extracted as a matrix.

At this time, the first identification matrix is a three-dimensional embedding vector '2', '1', '3' corresponding to each digit constituting '213', which is the serial number of 'real product 1'. [a ₂₁ b ₂₂ c ₂₃ ]', '[a ₁₁ b ₁₂ c ₁₃ ]', '[a ₃₁ b ₃₂ c ₃₃ ]' is a 3 x 3 first array matrix in which row vectors are sequentially arranged.

' and a preset validation matrix of size 3 x 3 '

' is a matrix generated by matrix multiplication with each other, '

'Let's assume it's the same.

Then, the first electronic terminal 140 transmits the first identification matrix ' to the metaverse service server 110.

' can be sent.

In this way, the two-dimensional code printed on the surface of 'real product 1' is scanned and recognized by the first electronic terminal 140, and the first identification matrix '

As ' is extracted, the first identification matrix ' from the first electronic terminal 140 to the metaverse service server 110

' is received, the disposition matrix restorer 118 determines the first identification matrix '

'Eh, the verification matrix '

' which is the inverse of '

By multiplying by ', the first arrangement matrix '

' can be restored.

In this way, when the first configuration matrix is restored by the configuration matrix restoration unit 118, the serial number checking unit 119 determines the first configuration matrix ' from the embedding vector storage unit 111 as shown in Table 1.

'[a ₂₁ b ₂₂ c ₂₃ ]', '[a ₁₁ b ₁₂ c ₁₃ ]', '[a ₃₁ b ₃₂ c ₃₃ ]', which are the three row vectors constituting ', are stored in correspondence with the same embedding vector. By sequentially extracting '2', '1', and '3', which are natural numbers, to form a three-digit serial number, the serial number of 'real product 1' can be identified as '213'.

In this way, when the serial number of '213' is confirmed by the serial number confirmation unit 119, the identification processing unit 120 corresponds to each real product stored in the serial number storage unit 112 as shown in Table 2 above. The serial numbers '213, 321, 111, ...' and the serial number '213' can be compared with each other.

As a result, if it is confirmed that both serial numbers for 'real product 1' among 'real product 1, real product 2, real product 3, ...' match each other, the identification processing unit 120 determines the 'real product 1' may be finally identified as a real product scanned by the first user 135.

When the first real product is identified as a real product scanned by the first user 135, the item information checking unit 116 refers to the item matching table for a first item matching the first real product. Check information.

When the information on the first item is confirmed, the identification code transmission unit 117 extracts a first identification code corresponding to the first item from the identification code storage unit 113, and transmits the first identification code to the first item. It is transmitted to the electronic terminal 140.

For example, as in the foregoing example, if 'real product 1' is identified as a real product scanned by the first user 135 by the real product identification unit 115, the item information confirmation unit 116 may check the table above. Information on 'item 1' matched to 'actual product 1' may be checked by referring to the item matching table shown in Fig. 5 .

In this way, when the information on 'item 1' is confirmed by the item information checking unit 116, the identification code transmission unit 117 sends a message corresponding to 'item 1' from the identification code storage unit 113 as shown in Table 4 above. After extracting the 'identification code 1', the 'identification code 1' may be transmitted to the first electronic terminal 140.

According to one embodiment of the present invention, when the identification code transmission unit 117 transmits the first identification code to the first electronic terminal 140, in order to prevent the first identification code from being exposed to others, The first identification code may be encrypted and transmitted to the first electronic terminal 140 .

In this regard, according to an embodiment of the present invention, the identification code transmission unit 117 includes an identification code extraction unit 121, an encryption event generation unit 122, a first hash value generation unit 123, and a first transmission unit. A processing unit 124 may be included.

The identification code extraction unit 121 extracts the first identification code corresponding to the first item from the identification code storage unit 113 when the information on the first item is confirmed.

When the first identification code is extracted, the encryption event generating unit 122 generates an encryption event for encrypting and transmitting the first identification code.

When the encryption event occurs, the first hash value generator 123 extracts n diagonal elements corresponding to the main diagonal of the first identification matrix, and concatenates the n diagonal elements After generating concatenated data by doing so, a first hash value is generated by applying the concatenated data as an input to a preset hash function.

When the first hash value is generated, the first transmission processing unit 124 encrypts the first identification code with the first hash value, and then converts the encrypted first identification code and the hash function to a first electronic terminal ( 140).

Hereinafter, operations of the identification code extractor 121, the encryption event generator 122, the first hash value generator 123, and the first transmission processor 124 will be described in detail by way of example.

First, as in the above example, when n is set to '3' and it is assumed that the information on 'item 1' is confirmed by the item information checker 116, the identification code extractor 121 is 'Identification code 1' corresponding to 'item 1' may be extracted from the same identification code storage unit 113 .

In this way, when 'identification code 1' is extracted by the identification code extractor 121, the encryption event generating unit 122 may generate an encryption event to encrypt and transmit 'identification code 1'.

In this way, when the encryption event is generated by the encryption event generator 122, the first hash value generator 123 generates the first identification matrix '

'a ₂₁ v ₁₁ +b ₂₂ v ₂₁ +c ₂₃ v ₃₁ , a ₁₁ v ₁₂ +b ₁₂ v ₂₂ +c ₁₃ v ₃₂ , a ₃₁ v ₁₃ +b ₃₂ v ₂₃ +c ₃₃ v ₃₃ ', and the three diagonal components 'a ₂₁ v ₁₁ +b ₂₂ v ₂₁ +c ₂₃ v ₃₁ , a ₁₁ v ₁₂ +b ₁₂ v ₂₂ +c ₁₃ v ₃₂ , a ₃₁ v ₁₃ +b ₃₂ v ₂₃ +c ₃₃ v ₃₃ ' can be concatenated to create concatenated data.

After that, the first hash value generating unit 123 may generate a first hash value such as '26d103c620a31345ag57qat327891703' by applying the concatenated data to a preset hash function as an input.

In this way, when the first hash value is generated by the first hash value generating unit 123, the first transmission processing unit 124 encrypts 'identification code 1' with the first hash value '26d103c620a31345ag57qat327891703', and then encrypts it. The 'identification code 1' and the hash function may be transmitted to the first electronic terminal 140 .

At this time, when the first electronic terminal 140 receives the encrypted first identification code and the hash function from the metaverse service server 110, it is extracted through a two-dimensional code printed on the surface of the first real product. The hash function received from the metaverse service server 110 after extracting the n diagonal elements corresponding to the main diagonal of the first identification matrix and generating the concatenated data by concatenating the n diagonal elements. The first hash value may be generated by applying the concatenated data as an input, and when the first hash value is generated, the encrypted first identification code may be decrypted with the first hash value.

Hereinafter, the operation of the first electronic terminal 140 will be described in detail by way of example.

First, as in the above example, as the first transmission processing unit 124 transmits the encrypted 'identification code 1' and the hash function to the metaverse service server 110, the first transmission from the metaverse service server 110 Assume that the electronic terminal 140 receives the encrypted 'identification code 1' and the hash function.

Then, the first electronic terminal 140 is the 'first identification matrix extracted through the two-dimensional code printed on the surface of 'real product 1'.

'a ₂₁ v ₁₁ +b ₂₂ v ₂₁ +c ₂₃ v ₃₁ , a ₁₁ v ₁₂ +b ₁₂ v ₂₂ +c ₁₃ v ₃₂ , a ₃₁ v ₁₃ +b ₃₂ v ₂₃ +c ₃₃ v ₃₃ ', and the three diagonal components 'a ₂₁ v ₁₁ +b ₂₂ v ₂₁ +c ₂₃ v ₃₁ , a ₁₁ v ₁₂ +b ₁₂ v ₂₂ +c ₁₃ The concatenated data may be generated by concatenating v ₃₂ , a ₃₁ v ₁₃ +b ₃₂ v ₂₃ +c ₃₃ v ₃₃ '.

After that, the first electronic terminal 140 applies the concatenated data as an input to the hash function received from the metaverse service server 110 to generate the first hash value such as '26d103c620a31345ag57qat327891703'.

In this way, when the first hash value is generated by the first electronic terminal 140, the first electronic terminal 140 can decrypt the 'identification code 1' encrypted with the first hash value '26d103c620a31345ag57qat327891703'.

According to one embodiment of the present invention, the metaverse service server 110 may further include an item activation processing unit 125.

As the item activation processing unit 125 receives an access request command for the metaverse service from the first electronic terminal 140, the metaverse environment according to the account of the first user 135 is provided to the first electronic terminal 140. In this provided state, when the first identification code is received from the first electronic terminal 140 and an activation command for the first item is received, with reference to the identification code storage 113, the first identification code is received. After identifying the first item corresponding to the code, activation is performed so that the first item becomes usable in the metaverse environment according to the account of the first user 135 .

For example, as an access request command for the metaverse service is received from the first electronic terminal 140 to the metaverse service server 110, the first electronic terminal 140 according to the account of the first user 135 Assume that an activation command for 'item 1' is received while 'identification code 1' is received from the first electronic terminal 140 to the metaverse service server 110 in a state in which the metaverse environment is provided.

Then, the item activation processing unit 125 identifies the 'item 1' corresponding to the 'identification code 1' by referring to the identification code storage unit 113 as shown in Table 4 above, and then identifies the account of the first user 135. In the metaverse environment according to , 'item 1' can be activated so that it becomes usable.

In relation to this, if 'item 1' is an accessory that can be worn on the avatar, the item activation processing unit 125 may activate 'item 1' in the form of wearing it on the avatar of the first user 135.

In the sales amount information database 126 , the plurality of items and sales amount information previously designated as corresponding to each of the plurality of items are stored in correspondence with each other.

For example, information as shown in Table 6 below may be stored in the sales price information database 126 .

multiple items	Sales Amount Information
item 1	KRW 230,000
item 2	300,000 won
item 3	70,000 won
...	...

The payment method information requesting unit 127 receives a purchase request command requesting to purchase a second item, which is any one of the plurality of items, from the second electronic terminal 150 possessed by the second user 145. After extracting the first sales amount information stored in correspondence with the second item from the sales amount information database 126, the second electronic terminal 150 is requested to transmit payment method information for payment. .

When the first payment method information is received from the second electronic terminal 150, the payment processing completion unit 128 performs payment processing for the amount according to the first sales amount information based on the first payment method information. complete
