< electronic Circuit of management Server 30 >

As shown in fig. 3, the electronic circuit of the management server 30 includes a control unit (CPU)31 as a computer, a storage unit 32, a recording medium reading unit 33, a communication unit 34, an input unit 35, and a display unit 36.

The control unit 31 controls the operations of the circuit units based on an input signal corresponding to a user operation from the input unit 35 or a received signal from the communication unit 34 of the communication device on the communication network N, in accordance with the server control program 32a stored in the storage unit 32. The server control program 32a may be stored in the storage unit 32 in advance, or may be read from an external recording medium M such as a CD-ROM via the recording medium reading unit 33 and stored in the storage unit 32.

The server control program 32a includes a program for executing an authentication determination function including at least the above-described functions (30a) to (30 g).

In the storage unit 32, an authentication determination target data storage area 32b, an encryption key storage area 32c, an electronic device (calculator) management data storage area 32d, and a job data storage area 32e are secured.

The authentication object data storage area 32b stores encrypted data of the function calculator 10F received by the communication unit 34 in accordance with the electronic device (calculator) confirmation function of the communication device (smartphone) 20, decrypted data obtained by decrypting the encrypted data, and data of an error detection code (checksum) calculated based on the decrypted data.

In the encryption key storage area 32c, data of an encryption key (32c) for decrypting the encrypted data of the function calculator 10F is stored. The encryption key (32c) is the same as the encryption key (14F) stored in the function calculator 10F at the time of manufacture of the function calculator 10F, for example.

In the electronic device (calculator) management data storage area 32d, data of the current ID request count of the function calculator 10F determined as a genuine product is stored, the data being included in the decrypted data stored in the authentication object data storage area 32b in association with the unique ID code of each function calculator 10F … manufactured by the manufacturer of the function calculator 10F.

In addition, when the unique ID code of the function calculator 10F obtained by decrypting the encrypted data received from the smartphone 20 exists in the electronic device (calculator) management data storage area 32d, that is, when the unique ID code matches the unique ID code stored in the electronic device (calculator) management data storage area 32d, the GPS position information and the date and time information of the smartphone 20 acquired together with the reception of the encrypted data from the smartphone 20 may be stored in association with the unique ID code. The GPS position information and the date and time information correspond to the position of the smartphone 20 on the earth and the date and time when the smartphone 20 performs the calculator check process, for example, with the function calculator 10F located in the storefront as the target, according to the calculator check application.

The job data storage area 32e temporarily stores various data generated or acquired by controlling the operations of the respective units of the control unit 31 as necessary.

The control unit 31 of the management server 30 configured as described above controls the operations of the circuit units in accordance with commands described in the server control program 32a, and realizes the authentication function described in the operation explanation below by cooperating software and hardware.

Next, the operation of the authentication system 1 according to the embodiment will be described.

Here, assume a scenario in which the user confirms whether the electronic device (function calculator) 10F located in the storefront is genuine or non-genuine, for example, using the communication device (smartphone) 20 in which the electronic device (calculator) confirmation application is installed.

The electronic device (function calculator) 10F may be powered on while being placed in the store by a battery power source BT including a solar battery, or the user in the store may operate the [ ID/communication ] key 11Q of the function calculator 10F to be confirmed to temporarily (for example, 60 seconds) activate the function calculator 10F by the battery power source BT.

In the smartphone 20, when the calculator confirms the activation of the application in response to the user operation (step T1), the control unit communicates with the function calculator 10F via the short-range wireless communication unit and transmits an ID request signal (step T2).

When the function calculator 10F receives the ID request signal transmitted from the smartphone 20 via the short-range wireless communication unit 16 (yes in step F1), the control unit 13 acquires the unique ID code (for example, "12345678") stored in the unique ID storage area 14b (step F2). Next, the control unit 13 reads the ID request count x stored in the ID request count storage area 14d (n: n is an integer equal to or greater than 0), and generates an ID request count x (n +1) that is incremented by 1 of the current ID request signal with respect to the read ID request count x (step F3).

The controller 13 serializes the acquired unique ID code and the incremented number of ID requests (step F4), and calculates the checksum of the data string "12345678A" that has been serialized (step F5). The sum (sum) value of the calculated checksums is stored in the error detection code storage area 14 e.

The control unit 13 serializes the unique ID code serialized in step F4 and the data string of the incremented number of ID requests by adding the sum of the checksums stored in the error detection code storage area 14e (step F6), and encrypts the data string serialized by the encryption key (for example, "YYYY") stored in the encryption key storage area 14g (step F7). The encrypted data (for example, "AB 2AEFA #") is temporarily stored in the encrypted data storage area 14 g.

The control unit 13 reads the encrypted data temporarily stored in the encrypted data storage area 14g, and transmits the read encrypted data to the smartphone 20 that is the source of the ID request in the communication connection (step F8).

In the smartphone 20, when receiving the encrypted data transmitted from the function calculator 10F (yes in step T3), the control unit transmits the received encrypted data to the management server 30 on the communication network N via the communication unit together with the GPS position information and the date and time information (step T4).

When the management server 30 receives the encrypted data "AB 2AEFA #" transmitted from the smartphone 20 via the communication unit 34 (yes in step S1), the control unit 31 decrypts the received encrypted data with the encryption key "YYYY" stored in the encryption key storage area 32c (step S2), and calculates a checksum for the unique ID code in the decrypted data string and the data string in the range corresponding to the incremented ID request count x (step S3). The sum of the received encrypted data, decrypted data, and calculated checksum is temporarily stored in the authentication target data storage area 32 b.

The control unit 31 compares the sum of the checksums calculated from the decrypted data with the data string corresponding to the range of the checksum sum included in the decrypted data, and determines whether or not the checksums match (step S4).

Here, when it is determined that the sum of the checksums calculated from the decrypted data does not match the data string corresponding to the range of the checksum value included in the decrypted data (step S4 (mismatch)), the encrypted data from the function calculator 10F that is the target of the authenticity determination is not normal, and it can be determined that the function calculator 10F is an authentic product.

As shown in fig. 6, the control unit 31 notifies the smartphone 20 of the authentication determination result "x" (non-genuine article) (step S5).

When receiving the authentication determination result "x" (non-genuine product) transmitted from the management server 30 in the smartphone 20 (yes in step T5), the control unit generates a non-genuine product determination screen GN as shown in fig. 6, causes the display unit 21 to display the non-genuine product determination screen GN, and notifies the user that the function calculator 10F to be the target of the current confirmation is a non-genuine product (step T6).

The non-genuine product determination screen GN may be generated and displayed on the display unit 21 in accordance with the calculator confirmation application from the smartphone 20 that received the notification of the authentication determination result "x" (non-genuine product).

On the other hand, in step S4 in the authentication determination process of the management server 30, when it is determined that the sum value of the checksum calculated from the decrypted data matches the data string corresponding to the range of the sum value of the checksum included in the decrypted data (step S4 (match)), the encrypted data from the function calculator 10F that is the subject of the authentication determination can be determined to be correct at least in terms of the form of the data string.

The control unit 31 determines whether or not the unique ID code matching the unique ID code included in the decrypted data is present in (stored in) the calculator management data storage area 32d (step S6).

Here, if it is determined that the unique ID code matching the unique ID code included in the decrypted data does not exist in the calculator managed data storage area 32d (no in step S6), it can be determined that the function calculator 10F to be subjected to the authentication determination is a non-genuine product.

As shown in fig. 6, the control unit 31 notifies the smartphone 20 of the authentication determination result "x" (non-genuine article) (step S5). In the smartphone 20, the user is notified that the function calculator 10F that is the subject of the current confirmation is a non-genuine product (step T5), and the smartphone 20 displays that the function calculator 10F that is the subject of the current confirmation is a non-genuine product (step T6).

On the other hand, in step S6 in the authentication determination process of the management server 30, when it is determined that the unique ID code "12345678" that matches the unique ID code included in the decrypted data is present in the computer management data storage area 32d (yes in step S6), it can be estimated that the unique ID code "12345678" of the function calculator 10F that is the target of the authentication determination matches the unique ID code of the genuine product, but there is a possibility that the function calculator 10F of the genuine product will be copied (simulated) together with the unique ID code "12345678".

In this case, the controller 31 increments the ID request count y (here, y is an integer equal to or greater than 0) stored in the calculator management data storage area 32d in association with the unique ID code "12345678" included in the decrypted data by 1 time of the encrypted data transmitted from the smartphone 20 this time, compares the incremented ID request count y with the incremented ID request count x included in the decrypted data (step S7), and determines whether or not the incremented ID request count x is equal to or greater than the incremented ID request count y (step S8).

Generally, a certain period of time is required after the genuine product is shelved in the storefront until a non-genuine product which is copied (imitated) is manufactured and marketed.

Here, for example, when the ID request count x obtained by the first calculator check process performed on the genuine product function calculator 10F by the smartphone 20 is 1, it is determined that the ID request count y incremented this time is equal to 1 (yes in step S8), and the value of the ID request count x is stored in the calculator management data storage area 32d as the value of the ID request count y (step S10). Next, the smartphone 20 is notified of data indicating that the result of the authenticity determination is "o" (genuine product) (step S11).

When the ID request count x obtained by the second calculator check process performed by the function calculator 10F according to the smartphone 20 is 2, the ID request count y stored in the calculator management data storage area 32d is determined as the incremented ID request count y of 2(x is y) (yes in step S8), and the calculator management data storage area 32d stores the ID request count x of 2 (step S10).

Even if the calculator check process of the smartphone 20 for the genuine function calculator 10F is repeated, for example, when the communication connection from the smartphone 20 to the management server 30 fails and the ID request count y associated with the unique ID code of the function calculator 10F stored in the calculator management data storage area 32d of the management server 30 is not updated for at least 1 time of the calculator check process, it is determined that the incremented ID request count x obtained from the function calculator 10F is larger than the ID request count y obtained in the past 1 time without being incremented (yes in step S8). In this case, the value of the ID request count x is stored in the computer management data storage area 32d, and the authentication determination result "o" (genuine product) is determined, and data indicating this is notified to the smartphone 20 (step S11).

When it is determined that the value of the ID request count x obtained by the calculator check process performed by the function calculator 10F of the genuine product by the smartphone 20 is smaller than the value of the ID request count y incremented this time (no in step S8), it is determined as the authenticity determination result "Δ" (there is a possibility that the genuine product is not genuine), and data indicating the result is notified to the smartphone 20 (step S9). In this case, since the product is not genuine, the counter management data storage area 32d is not caused to store the incremented value of the number y of ID requests. Then, even if encrypted data including an inherent ID code that matches the inherent ID code of the data string obtained by decrypting the encrypted data received this time from the smartphone 20 is received later, the authenticity determination result "Δ" (which may not be a genuine product) is always notified to the smartphone 20 (communication device) that transmitted the encrypted data, without comparing the value of the ID request number x and the value of the ID request number y.

In this way, the management server 30 reads the incremented ID request count x obtained from the function calculator 10F in accordance with the calculator verification process of the smartphone 20 from the calculator management data storage area 32d, and performs the authenticity determination in accordance with the result of comparison with the currently incremented ID request count y. If it is determined that the value of the ID request count x matches or is greater than the value of the current incremented ID request count y (yes in step S8), it can be determined that the function calculator 10F is a genuine product (genuine product).

On the other hand, if it is determined that the value of the ID request count x obtained from the function calculator 10F is smaller than the value incremented by the ID request count y stored in the calculator management data storage area 32d in association with the unique ID code of the function calculator 10F (no in step S8), it is also considered that, for example, if the ID request count y is updated to a large value because a large number of calculator confirmation processes are repeated for the function calculator 10F having the same unique ID code as in the past, the function calculator 10F that is the target of the authenticity determination cannot be determined to be a non-genuine product (counterfeit), but the function calculator 10F that is determined to have indeed generated a non-genuine product can be determined.

Further, the control unit 31 may store a flag indicating the occurrence of an unauthorized product in association with the unique ID code of the function calculator 10F stored in the calculator management data storage area 32d, and may not perform the ID request count x described above when the same unique ID code as the unique ID code having the flag is included in the decrypted data in the subsequent authenticity determination processing (yes in step S6): y (steps S7 and S8), and the function calculator 10F determines that a non-genuine product has occurred.

When the controller 31 determines that the value of the ID request count x obtained from the function calculator 10F by the calculator check process of the smartphone 20 is smaller than the value of the ID request count y stored in the calculator management data storage area 32d in association with the unique ID code of the function calculator 10F (no in step S8), it notifies the smartphone 20 of data indicating that the authenticity determination result is "Δ" (which may not be a genuine article) (step S9).

When the smartphone 20 receives data indicating that the authentication determination result transmitted from the management server 30 is "Δ" (there is a possibility of being a non-genuine product) (yes in step T5), the control unit causes the display unit 21 to display a determination screen GM on which a non-genuine product is possible, and notifies the user that the function calculator 10F to which the user is to confirm this time is a possibility of being a non-genuine product (step T6), as shown in fig. 7.

Further, although the smartphone 20 that has received the notification of the authenticity determination result "Δ" (there is a possibility that the non-genuine product is not genuine) is generated and displayed on the display unit 21 in accordance with the calculator confirmation application, the management server 30 may generate the determination screen GM that has a possibility of being a non-genuine product and transmit the image data to the smartphone 20.

Further, the control unit 31 obtains the value of the ID request count x from the function calculator 10F in accordance with the calculator check processing of the smartphone 20, reads out the value of the ID request count y from the calculator management data storage area 32d in association with the unique ID code of the function calculator 10F, and when it is determined that the value of the ID request count x is equal to or greater than the value of the incremented ID request count y (yes in step S8), stores the value of the ID request count x as the incremented ID request count y in the calculator management data storage area 32d (step S10). Then, as shown in fig. 8, the smartphone 20 is notified of data indicating that the result of the authenticity determination is "o" (genuine product) (step S11).

When the smartphone 20 receives data indicating that the authentication determination result transmitted from the management server 30 is "o" (genuine product) (yes in step T5), the control unit generates a genuine product determination screen GH indicating the authentication determination result "o", causes the display unit 21 to display the genuine product determination screen GH, and notifies the user that the function calculator 10F, which is the target of the current confirmation, is a genuine product (step T6), as shown in fig. 8.

The genuine product determination screen GH is generated and displayed on the display unit 21 in accordance with the calculator confirmation application in the smartphone 20 that has received the notification of the authenticity determination result "o" (genuine product), but the management server 30 may generate the genuine product determination screen GH and transmit the image data to the smartphone 20.

(summary of the embodiment)

According to the authentication system 1 of the embodiment, when the function calculator 10F of the authentication target receives the ID request signal from the smartphone 20 in accordance with the calculator verification application installed in the smartphone 20, the function calculator 10F performs data serialization of the unique ID code itself and the ID request frequency, which is the frequency of receiving the ID request signal, and calculates the checksum. Then, the unique ID code, the data string of the ID request count and the calculated sum value are encrypted by a specific encryption key, and the encrypted data is transmitted to the smartphone 20. The smartphone 20 transmits the encrypted data received from the function calculator 10F to the management server 30.

The management server 30 decrypts the received encrypted data with a specific encryption key, calculates a checksum of a data string corresponding to the range of the unique ID code and the ID request count in the decrypted data, and determines whether or not the calculated sum value matches the data string corresponding to the range of the sum value of the decrypted data. When the calculated sum value does not match the data string corresponding to the range of the sum value of the decrypted data, the authentication result "x" (non-genuine product) is notified to the smartphone 20, and the display unit 21 of the smartphone 20 can display a non-genuine product determination screen GN.

Even when the calculated sum value matches the data string corresponding to the range of the sum value of the decrypted data, the management server 30 can determine whether or not the unique ID code of the decrypted data exists as the unique ID code of the genuine product stored in the calculator management data storage area 32d, and when the unique ID code of the decrypted data does not exist as the unique ID code of the genuine product, can notify the smartphone 20 of the authentication determination result "x" (non-genuine product) and cause the display unit 21 to display the non-genuine product determination screen GN.

Even when the unique ID code of the decrypted data exists as the unique ID code of the genuine product, the management server 30 can determine whether or not the value of the ID request count x of the decrypted data is equal to or greater than the value of the ID request count y stored in the calculator management data storage area 32d in association with the unique ID code of the genuine product, and when the value of the ID request count x of the decrypted data is smaller than the value of the ID request count y, notify the smart phone 20 of the authentication result "Δ" (which may not be a genuine product) and display the determination screen GM on the display unit 21, which may be a non-genuine product.

In addition, when the value of the ID request count x of the decrypted data is equal to or greater than the value of the ID request count y, the management server 30 can update the ID request count y of the calculator management data storage area 32d based on the ID request count x, notify the smartphone 20 of the authenticity determination result "∘" (genuine article), and cause the display unit 21 to display a genuine article determination screen GH.

Therefore, the authenticity determination of the product body can be performed with higher reliability than the conventional authenticity determination system.

In addition, according to the authentication system 1 of the embodiment, the number of ID requests included in the encrypted data of the function calculator 10F is updated (incremented) and stored in the function calculator 10F each time an ID request signal is received from the smartphone 20, and communication is performed in an encrypted state also when the number of ID requests in the function calculator 10F for which a genuine product is output to the outside.

(other embodiments)

Even when the unique ID code of the function calculator 10F as the authentication target included in the decrypted data exists as the unique ID code of the genuine product stored in the calculator management data storage area 32d, the management server 30 notifies that the authentication result is "Δ" (there is a possibility that the genuine product is not genuine) or that the authentication result is "x" (non-genuine product) when the function calculator 10F cannot move temporally and positionally with respect to the date and time of the position and date and time information of the GPS position information stored in association with the same unique ID code in the past when it can be determined that the position and date and time information of the GPS position information acquired from the smartphone 20.

In the management server 30, the position of the smartphone 20 checked by the function calculator 10F may be acquired as a position in a region unit based on the IP address when the smartphone 20 is connected to the management server 30 in a communication manner, instead of the GPS position information.

In the authentication system 1 according to the embodiment described with reference to fig. 1 to 8, in accordance with the electronic device (calculator) confirmation process (1) according to the smartphone 20, the ID request signal transmitted from the smartphone 20 (steps T1, T2) is received by the function calculator 10F via the short-range wireless communication unit 16 (yes in step F1), the function calculator 10F executes the ID request handling process (1), and transmits the encrypted data of the data string obtained by adding the unique ID code of the function calculator 10F, the incremented number of ID requests, and the sum of the checksums to the smartphone 20 that is the ID request source (steps F2 to F8).

Then, the smartphone 20 receives the transmitted encrypted data from the function calculator 10F via the short-range wireless communication unit 16 (yes in step T3), transmits the received encrypted data to the management server 30 (step T4), and executes a series of electronic device (calculator) confirmation processes (1) (steps T5 and T6).

On the other hand, even if the function calculator 10F does not have a communication function with the smartphone 20 such as the short-range wireless communication unit 16, as described in the authentication determination system 100 (see fig. 9 and 10) of another embodiment below, the encrypted data of the data string obtained by adding the unique ID code, the incremented ID request count, and the sum of the checksums is displayed on the display unit 12 as a two-dimensional code (identifier) Q such as a QR code by the function calculator 10F, and the displayed two-dimensional code Q is picked up and read by the image pickup unit 22 of the smartphone 20, so that the smartphone 20 transmits the encrypted data corresponding to the two-dimensional code Q to the management server 30, and the electronic device (calculator) confirmation process can be executed in the same manner as in the above-described embodiment.

In the authentication system 100 according to another embodiment, when the control unit 13 of the function calculator 10F has received a specific operation by a user (operator), it determines that there is an ID request (yes in step F21), acquires the unique ID code stored in the unique ID storage area 14b (step F2), and increments the ID request count x stored in the ID request count storage area 14d (step F3).

The user's specific operation may be, for example, an operation of simultaneously pressing a plurality of keys preset in the key input unit 11, an operation of simultaneously touching a plurality of areas preset in the display unit 12 when the display unit 12 is a touch panel display unit, or the like.

In addition, when the function calculator 10F is disposed in the storefront, the power supply thereof may be turned on by the battery power supply BT including a solar battery as in the above-described embodiment, or may be turned on temporarily (for example, for 60 seconds) by the battery power supply BT according to a specific operation by the user. In this case, the function calculator 10F may be partially or entirely packaged with a transparent packaging material so that the battery power source BT (including the key input unit 11 and the like as necessary) can be visually recognized from the outside of the packaging material covering the function calculator 10F and a specific operation can be performed by the user with the packaging material interposed therebetween.

Then, the control unit 13 of the function calculator 10F displays the encrypted data of the data string obtained by adding the unique ID code, the incremented number of ID requests x, and the sum of the checksums, as the two-dimensional code Q, on the display unit 12 (steps F4 to F7, F28).

The control unit of the smartphone 20 starts the identifier reading application (step T22) together with the calculator check application start (step T1) in response to the user operation, and the two-dimensional code Q of the encrypted data displayed on the display unit 12 of the function calculator 10F is imaged and read by the imaging unit 22 (step T23).

Then, the control unit of the smartphone 20 transmits the encrypted data obtained by reading the two-dimensional code Q to the management server 30 together with the GPS position information and the date and time information (step T4) in the same manner as in the above-described embodiment, and displays the authentication result of the function calculator 10F obtained by the authentication determination process (see fig. 5) of the management server 30 on the display unit 21 (steps T5 and T6).

As described above, according to the authentication determination system 100 of the other embodiment, even if the function calculator 10F does not have the communication function with the smartphone 20, the smartphone 20 can execute the electronic device (calculator) verification process (2) in the same manner as in the above-described embodiment, and can display the authentication determination result with high reliability of the function calculator 10F main body. In the above embodiment, the identifier is not limited to the two-dimensional code, and may be a one-dimensional code or an identifier of another specification.
