In this situation, when a command to perform genuine product authentication for a first product, which is one of the plurality of products, is received by the user of the electronic terminal device 110, the camera activation unit 111 The camera pre-loaded on the electronic terminal device 110 is activated to scan the two-dimensional code.

In this way, after the camera is activated by the camera activation unit 111, when the two-dimensional code printed on the first product by the user is located in front of the camera, the main identification number extractor 112 By scanning and recognizing the two-dimensional code printed on the first product, the first main identification number, which is the main identification number for the first product, can be extracted from the two-dimensional code printed on the first product.

In this way, when the first main identification number is extracted by the main identification number extraction unit 112, the input instruction message display unit 113 provides an instruction to input the auxiliary identification number for the first product. Create a message and display it on the screen.

In this way, after the auxiliary identification number input instruction message is displayed by the input instruction message display unit 113, the first auxiliary identification number is entered as the auxiliary identification number for the first product by the user within a first preset waiting time. When input, the token calculation unit 114 calculates a first authentication token by applying the first primary identification number and the first auxiliary identification number as input to the token generation function.

At this time, according to one embodiment of the present invention, the token calculation unit 114 configures the first main identification number by applying the first main identification number and the first auxiliary identification number as input to the token generation function. After generating a first operation matrix with a size of n 1 The Euclidean norm of the operation matrix can be calculated using the first authentication token.

When the first authentication token is calculated, the confirmation request unit 115 transmits the first authentication token and the first auxiliary identification number to the product information server 130, and determines whether the first product is genuine. Send a confirmation request.

In relation to this, the operations of the token calculation unit 114 and the confirmation request unit 115 will be described in detail using an example.

First, let 'n=5', 'k=6', the first primary identification number for the first product is '32123', and the first auxiliary identification for the first product entered by the user. Let's assume the number is '123321'.

Then, the token calculation unit 114 inputs '32123', which is the first main identification number, and '123321', which is the first auxiliary identification number, to the token generation function, thereby generating '32123', which is the first main identification number. ', a column vector whose components are the five numbers that make up ' ' and ', a row vector whose components include six numbers constituting '123321', the first auxiliary identification number. ' The Kronecker product between ' is calculated according to Equations 2 to 4 above to obtain a first operation matrix of size 5 x 6. ' can be created.

Then, the token calculation unit 114 calculates the Euclidean norm of the first operation matrix as '27.49' according to Equation 1, and then uses '27.49', which is the Euclidean norm of the first operation matrix, for the first authentication. It can be calculated with tokens.

In this way, when the first authentication token is calculated by the token calculation unit 114, the confirmation request unit 115 sends '27.49', the first authentication token, and the first auxiliary identification number to the product information server 130. While transmitting '123321', a request for confirmation as to whether the first product is genuine can be transmitted.

At this time, according to an embodiment of the present invention, the product information server 130 receives the first authentication token and the first auxiliary identification number from the electronic terminal device 110, and receives the first authentication token from the electronic terminal device 110. 1 When a request for confirmation of whether a product is genuine is received, authentication stored in correspondence with the first auxiliary identification number from the product information database is performed based on the first auxiliary identification number received from the electronic terminal device 110. As a result of extracting a token and comparing the extracted authentication token with the first authentication token received from the electronic terminal device 110, when it is confirmed that both authentication tokens match each other, the first product is considered genuine. After generating a feedback message indicating confirmation, the feedback message can be transmitted to the electronic terminal device 110.

For example, as in the above-described example, the first authentication token '27.49' and the first auxiliary identification number '123321' are received from the electronic terminal device 110 to the product information server 130, and the electronic terminal device ( Let's assume that a request to confirm whether the first product is genuine is received from the product information server 130 from 110).

Then, the product information server 130 generates the first auxiliary identification number '123321' from the product information database shown in Table 1 based on the first auxiliary identification number '123321' received from the electronic terminal device 110. You can extract 'Authentication Token 1', which is the authentication token stored in correspondence with .

Afterwards, the product information server 130 compares the extracted authentication token 'authentication token 1' with the first authentication token '27.49' received from the electronic terminal device 110, and as a result, both authentication tokens are different from each other. If confirmed to match, the first state identification number '32123' included in the two-dimensional code printed on the first product can be considered to be the correctly issued state identification number, so the first product After generating a feedback message indicating that the product has been confirmed as genuine, the feedback message can be transmitted to the electronic terminal device 110.

In this way, when the feedback message indicating that the first product has been confirmed to be genuine is received from the product information server 130 to the electronic terminal device 110, the product authentication message display unit 116 displays a preset product authentication message on the screen. Displays .

At this time, according to one embodiment of the present invention, the product authentication message display unit 116 may include a table maintenance unit 122 and a message display unit 123.

The table maintenance unit 122 stores and maintains a table in which information on a plurality of preset countries and product authentication messages written in the languages of each of the plurality of countries are recorded in correspondence with each other.

For example, the table maintenance unit 122 may store and maintain a table as shown in Table 3 below.

Information about multiple countries Activation message written in each country's language korea Product Authentication Message 1 (Korean Version) USA Product activation message 2 (English Version) japan Activation message 3 (Japanese Version) ... ...

When the feedback message is received from the product information server 130, the message display unit 123 displays the current location of the electronic terminal device 110 based on the GPS (Global Positioning System) preloaded in the electronic terminal device 110. By confirming, the first country, which is the country to which the current location belongs, is determined, the product activation message written in the language of the first country recorded corresponding to the first country is extracted from the table, and then the first country is displayed on the screen. 1 Displays an activation message written in the language of the country.

For example, when the feedback message is received from the product information server 130 to the electronic terminal device 110, the message display unit 123 displays the electronic terminal device ( By checking the current location of 110), it is possible to determine the first country to which the current location belongs.

At this time, if the first country, which is the country to which the current location belongs, is determined to be 'the United States', the message display unit 123 displays 'authentication message 2' recorded corresponding to 'the United States' from the table shown in Table 3 above. After extracting ‘(English Version)’, ‘Authentication Message 2 (English Version)’ can be displayed on the screen.

In addition, according to one embodiment of the present invention, when the feedback message is received from the product information server 130, the product authentication message display unit 116 synthesizes the product authentication message into voice using a predetermined voice synthesis model. Then, the voice can be output through the speaker. Through this, the user can check whether the first product he or she purchased is genuine.

In this way, when the product authentication message is displayed on the screen by the product authentication message display unit 116, the additional information guide message display unit 117 provides additional information information indicating that additional information about the first product can be additionally confirmed. Create a message and display it on the screen.

Thereafter, when a command to display additional information about the first product is received by the user on the electronic terminal device 110, the input guidance message display unit 118 displays an input guidance message requesting the user to input biometric information. Create it and display it on the screen.

In this way, after the input guidance message is displayed by the input guidance message display unit 118, the biometric information is applied by the user within the second preset waiting time through the biometric information input device preloaded on the electronic terminal device 110. If so, the authentication request unit 119 transmits an authentication request for the user's biometric information to the biometric information authentication server 140.

At this time, after the input guidance message is displayed, if biometric information is applied by the user through the biometric information input device within the second waiting time, the authentication request unit 119 collects the unique identification information of the electronic terminal device 110. After applying the input to the hash function to generate first identification information for the user, the first identification information and the user's biometric information are transmitted to the biometric information authentication server 140, and the user's biometric information An authentication request can be sent.

At this time, when the biometric information authentication server 140 receives the first identification information and the user's biometric information from the electronic terminal device 110 and receives an authentication request for the user's biometric information, the biometric information authentication database When it is confirmed whether the biometric information stored in correspondence with the first identification information matches the user's biometric information received from the electronic terminal device 110, and it is confirmed that both biometric information matches each other, , After generating an authentication completion message indicating that authentication of the user's biometric information has been completed, the authentication completion message may be transmitted to the electronic terminal device 110.

For example, as in the above-described example, assume that biometric information is authorized by the user through the biometric information input device within the second waiting time after the input guidance message is displayed by the input guidance message display unit 118.

Then, the authentication request unit 119 may apply the unique identification information of the electronic terminal device 110 as input to the hash function to generate first identification information for the user.

If the first identification information for the user is generated as '13d013c520a21245ag71qat327898412', the authentication request unit 119 is the biometric information authentication server 140, and the first identification information '13d013c520a21245ag71qat327898412' and the user's biometric information. While transmitting information, an authentication request for the user's biometric information may be transmitted.

At this time, the first identification information '13d013c520a21245ag71qat327898412' and the user's biometric information are received from the electronic terminal device 110 to the biometric information authentication server 140, and the biometric information authentication server 140 is received from the electronic terminal device 110. When an authentication request for the user's biometric information is received, the biometric information authentication server 140 stores biometric information corresponding to '13d013c520a21245ag71qat327898412', which is the first identification information, on the biometric information authentication database as shown in Table 2 above. It can be confirmed whether 'biometric information 1' matches the user's biometric information received from the electronic terminal device 110.

At this time, when it is confirmed that both biometric information matches each other, the biometric information authentication server 140 generates an authentication complete message indicating that authentication of the user's biometric information has been completed, and then sends the authentication complete message electronically. It can be transmitted to the terminal device 110.

In this way, when the authentication completion message indicating that authentication of the user's biometric information has been completed is received from the biometric information authentication server 140 to the electronic terminal device 110, the additional information request unit 120 sends the product information server ( 130), requesting transmission of additional information about the first product.

At this time, according to an embodiment of the present invention, when a request for transmission of additional information about the first product is received from the electronic terminal device 110, the product information server 130 responds to the request for transmission of the additional information, After extracting first additional information, which is additional information stored in correspondence with the first auxiliary identification number, from the product information database, the first additional information can be transmitted to the electronic terminal device 110.

In this way, when the first additional information is received from the product information server 130 to the electronic terminal device 110, the additional information display unit 121 additionally displays the first additional information on the screen.
