For example, the first electronic stamp receives the membership ID related to the first coffee app which is being executed in the first terminal and the identification information of the first terminal which are transmitted from the first terminal. Further, the first electronic stamp generates an eleventh OTP (S630).
Next, the electronic stamp 100 combines the generated one-time password and the previously received membership ID to generate an encrypted value.

For example, the first electronic stamp combines the generated eleventh OTP and the membership ID related to the first coffee app which is being executed in the first terminal to generate an encrypted eleventh value. Further, the first electronic stamp transmits the eleventh value (or the encrypted eleventh value) to the first terminal (S640).
Next, the terminal 200 receives the encrypted value transmitted from the electronic stamp 100 in response to the membership ID related to an app which is being executed in the terminal 200 (or a membership ID related to a user of the terminal 200) and identification information of the terminal 200 which are previously transmitted.

Here, the electronic stamp information includes an electronic stamp ID used to generate a description key for decrypting the encrypted value.
For example, the first terminal receives the eleventh value (or the encrypted eleventh value) transmitted from the first electronic stamp in response to the membership ID related to the first coffee app which is being executed in the first terminal and the identification information of the first terminal.
Further, the first terminal transmits the membership ID related to the first coffee app which is being executed in the first terminal, the electronic stamp information, the eleventh value (or the encrypted eleventh value), and the identification information of the first terminal to the first electronic stamp server 300 (S650).

That is, the electronic stamp server 300 obtains a decryption key from the extracted electronic stamp ID.
For example, the first electronic stamp server generates a first decryption key based on the extracted first electronic stamp ID (S670).
Next, the electronic stamp server 300 decrypts the encrypted value which is previously received based on the generated (or obtained) decryption key.
For example, the first electronic stamp server decrypts the eleventh value (or an encrypted eleventh value) based on the generated (or obtained) first decryption key to obtain a twenty first value (or a decoded twenty first value) (S680).
Next, the electronic stamp server 300 compares the decrypted value with the previously received membership ID to verify (or determine) authenticity of the electronic stamp.
For example, the first electronic stamp server checks whether the twenty first (or the decrypted twenty first) is identical with the membership ID related to the first coffee app which is being executed in the first terminal (S690).
Next, the electronic stamp server 300 transmits information on the verified (or determined) authenticity of the electronic stamp to the terminal 200. Here, the information on the authenticity of the electronic stamp includes information indicating that the electronic stamp is genuine and information indicating that the electronic stamp is forged.

As another example, when the twenty first value (or the decrypted twenty first value) is different from the membership ID related to the first coffee app which is being executed in the first terminal, the first electronic stamp server confirms that the electronic stamp is forged and transmits the information indicating the electronic stamp is forged, to the first terminal (S700).
Next, the terminal 200 receives information on authenticity of the electronic stamp transmitted from the electronic stamp server 300 in response to the membership ID related to an app which is being executed in the terminal 200 (or a membership ID related to a user of the terminal 200), the electronic stamp information, the encrypted value, and identification information of the terminal 200 which are previously transmitted.
Further, the terminal 200 determines whether to perform a stamp accumulating function (or whether to perform an electronic stamp sealing function) related to the electronic stamp, based on the received information on the authenticity of the electronic stamp.
That is, when it is verified that the electronic stamp is genuine, the terminal 200 performs the stamp accumulating function (or the electronic stamp sealing function) related to the electronic stamp and displays the stamp accumulating function performing result (or the electronic stamp sealing function performing result).
Further, when it is verified that the electronic stamp is forged, the terminal 200 stops the stamp accumulation related to the electronic stamp (or stamp accumulating function/the electronic stamp sealing function) and displays information indicating that the electronic stamp is forged.
For example, the first terminal receives information indicating that the electronic stamp transmitted from a first electronic stamp server is genuine in response to the membership ID related to the first coffee app which is being executed in the first terminal, the electronic stamp information, an eleventh value (or an encrypted eleventh value), and identification information of the first terminal which are previously transmitted, performs the stamp accumulating function of the first coffee app through the electronic stamp based on the received information indicating that the electronic stamp is genuine, and displays a result 810 that the stamp is accumulated through the first coffee app, as illustrated in

Further, the electronic stamp 100 transmits recognized fingerprint information and electronic stamp information (for example, including an electronic stamp ID) to an electronic stamp server 300.
For example, a first electronic stamp 100 related to a coffee shop recognizes a fingerprint of a manager of the coffee shop who wants to use the first electronic stamp.
Further, the first electronic stamp transmits electronic stamp information including first recognized fingerprint information of the manager and an ID of the first electronic stamp to the first electronic stamp server 300 (S910).
Next, the electronic stamp server 300 receives the fingerprint information and the electronic stamp information (including the electronic stamp ID) transmitted from the electronic stamp 100.
Further, the electronic stamp server 300 performs an authentication process on the fingerprint information based on the received fingerprint information and electronic stamp information.

Here, there may be one or more fingerprint information which is registered in advance correspondingly to the electronic stamp information.
For example, the first electronic stamp server checks whether a plurality of fingerprint information registered in relation to a plurality managers of the coffee shop correspondingly to the electronic stamp information matches first fingerprint information transmitted from the first electronic stamp (S920).
As the checking result (or the determination result), when the fingerprint information which is registered in advance in the electronic stamp server 300 correspondingly to the electronic stamp information does not match the previously received fingerprint information (or when there is no fingerprint information which matches the previously received fingerprint information among a plurality of fingerprint information registered in advance in the electronic stamp server 300 correspondingly to the electronic stamp information), the electronic stamp server 300 transmits the fingerprint mismatching information indicating that the fingerprint information does not match the fingerprint information which is registered in advance (or the authentication failure information indicating that the authentication process is failed) to the electronic stamp 100.
For example, when there is no fingerprint information which matches the first fingerprint information transmitted from the first electronic stamp among the plurality of fingerprint information registered in relation to the plurality of managers of the coffee shop correspondingly to the electronic stamp information, the first electronic stamp server transmits fingerprint mismatching information (or authentication failure information) indicating that the first fingerprint information does not match the fingerprint information which is registered in advance (S930).
Next, the electronic stamp 100 receives the fingerprint mismatching information (or the authentication failure information) transmitted from the electronic stamp server 300 in response to the previously transmitted fingerprint information and the electronic stamp information (including the electronic stamp ID).
Further, the electronic stamp 100 maintains an one-time password generating unit 120 in the electronic stamp 100 to be in an inactivation state based on the received fingerprint mismatching information.
For example, the first electronic stamp receives the fingerprint mismatching information (or the authentication failure information) transmitted from the first electronic stamp server in response to the previously transmitted fingerprint information and the electronic stamp information including an ID of the first electronic stamp and maintains the one-time password generating unit 120 in the first electronic stamp to be in an inactivation state based on the received fingerprint mismatching information (S940).
Further, as the checking result (or the determination result), when the fingerprint information which is registered in advance in the electronic stamp server 300 correspondingly to the electronic stamp information matches the previously received fingerprint information (or when there is fingerprint information which matches the previously received fingerprint information among a plurality of fingerprint information registered in advance in the electronic stamp server 300 correspondingly to the electronic stamp information), the electronic stamp server 300 transmits the fingerprint matching information indicating that the fingerprint information matches the fingerprint information which is registered in advance (or the authentication success information indicating that the authentication process is successfully performed) to the electronic stamp 100.
For example, when there is fingerprint information which matches the first fingerprint information transmitted from the first electronic stamp among the plurality of fingerprint information registered in relation to the plurality of managers of the coffee shop correspondingly to the electronic stamp information, the first electronic stamp server transmits fingerprint matching information (or authentication success information) indicating that the first fingerprint information matches the fingerprint information which is registered in advance (S950).
Next, the electronic stamp 100 receives the fingerprint matching information (or the authentication success information) transmitted from the electronic stamp server 300 in response to the previously transmitted fingerprint information and the electronic stamp information (including the electronic stamp ID).
Further, the electronic stamp 100 activates the one-time password generating unit 120 in the electronic stamp 100 so as to use the electronic stamp based on received fingerprint matching information.
For example, the first electronic stamp receives the fingerprint matching information (or the authentication success information) transmitted from the first electronic stamp server in response to the first fingerprint information of the manager and the electronic stamp information including an ID of the first electronic stamp which are previously transmitted and activates the one-time password generating unit 120 in the first electronic stamp to be in a standby-state so as to use the first electronic stamp based on the received fingerprint matching information (S960).
Thereafter, when the electronic stamp 100 is in contact with an electrostatic screen of the terminal 200 while executing an app (or application) which recognizes the electronic stamp 100 in the terminal 200, the terminal 200 is connected (or communicates) with the electronic stamp 100 by short range communication. Here, the short range communication technique may include Bluetooth, radio frequency identification (RFID), infrared data association (IrDA), ultra wideband (UWB), ZigBee, near field communication (NFC), ultra sound communication (USC), visible light communication (VLC), Wi-Fi, Wi-Fi direct, or the like.
That is, when a stamp accumulating function and an electronic stamp sealing function are provided through the electronic stamp 100 in association with the app which is being executed in the terminal 200, the electronic stamp 100 is in contact with the electrostatic screen of the terminal 200 to be connected with the terminal 200 through the short range communication.
For example, when a user of the first terminal orders (or makes a payment for) coffee using a coffee shop and then the first electronic stamp related to the coffee shop is in contact with a screen of the first terminal while executing a first coffee app related to the coffee shop in the first terminal related to the user, the first electronic stamp is connected to the first terminal by a Bluetooth communication scheme (S970).
Next, the terminal 200 transmits a membership ID related to an app which is being executed in the terminal 200 (or a membership ID related to a user of the terminal 200) and identification information of the terminal 200, to the electronic stamp 100. Here, the identification information of the terminal 200 includes an MDN, a mobile IP, a mobile MAC, a subscriber identify module (Sim) card unique information, and a serial number.
For example, the first terminal transmits the membership ID related to the first coffee app which is being executed in the first terminal and the identification information of the first terminal to the first electronic stamp (S980).
Next, the electronic stamp 100 receives a membership ID related to an app which is being executed in the terminal 200 (or a membership ID related to a user of the terminal 200) and identification information of the terminal 200 which are transmitted from the terminal 200.
Further, the electronic stamp 100 generates a one-time password such as an OTP. In this case, when the one-time password generating unit 120 in the electronic stamp 100 is in an activation state, the electronic stamp 100 may generate the one-time password in accordance with the previously received fingerprint matching information. In this case, when the one-time password generating unit 120 in the electronic stamp 100 is in an inactivation state, the electronic stamp 100 cannot generate the one-time password in accordance with the previously received fingerprint mismatching information.
For example, when the one-time password generating unit 120 in the first electronic stamp is in an inactivation state, even though a membership ID related to the first coffee app which is being executed in the first terminal and the identification information of the first terminal which are transmitted from the first terminal are received, the first electronic stamp does not generate an OTP.
As another example, when the one-time password generating unit 120 in the first electronic stamp is in an activation state, the first electronic stamp receives the membership ID related to the first coffee app which is being executed in the first terminal and the identification information of the first terminal which are transmitted from the first terminal and generate an eleventh OTP (S990).
Next, the electronic stamp 100 combines the generated one-time password and the previously received membership ID to generate an encrypted value.
Further, the electronic stamp 100 transmits the generated encrypted value to the terminal 200.
For example, the first electronic stamp combines the generated eleventh OTP and the membership ID related to the first coffee app which is being executed in the first terminal to generate an encrypted eleventh value. Further, the first electronic stamp transmits the eleventh value (or the encrypted eleventh value) to the first terminal (S1000).
Next, the terminal 200 receives the encrypted value transmitted from the electronic stamp 100 in response to the membership ID related to an app which is being executed in the terminal 200 (or a membership ID related to a user of the terminal 200) and identification information of the terminal 200 which are previously transmitted.
Next, the terminal 200 transmits a membership ID related to an app which is being executed in the terminal 200 (or a membership ID related to a user of the terminal 200), the electronic stamp information, the encrypted value, and identification information of the terminal 200, to the electronic stamp server 300. Here, the electronic stamp information includes an electronic stamp ID used to generate a description key for decrypting the encrypted value.
For example, the first terminal receives the eleventh value (or the encrypted eleventh value) transmitted from the first electronic stamp in response to the membership ID related to the first coffee app which is being executed in the first terminal and the identification information of the first terminal.
Further, the first terminal transmits the membership ID related to the first coffee app which is being executed in the first terminal, the electronic stamp information, the eleventh value (or the encrypted eleventh value), and the identification information of the first terminal to the first electronic stamp server 300 (S1010).
Next, the electronic stamp server 300 receives the membership ID related to an app which is being executed in the terminal 200 (or a membership ID related to a user of the terminal 200), the electronic stamp information, the encrypted value, and identification information of the terminal 200 which are transmitted from the terminal 200.
Further, the electronic stamp server 300 extracts the electronic stamp ID from the received electronic stamp information.
For example, the first electronic stamp server receives the membership ID related to the first coffee app which is being executed in the first terminal, the electronic stamp information, the eleventh value (or the encrypted eleventh value), and the identification information of the first terminal which are transmitted from the first terminal.
Further, the first electronic stamp server extracts the first electronic stamp ID from the received electronic stamp information (S1020).
Next, the electronic stamp server 300 generates a decryption key based on the extracted electronic stamp ID.
That is, the electronic stamp server 300 obtains a decryption key from the extracted electronic stamp ID.
For example, the first electronic stamp server generates a first decryption key based on the extracted first electronic stamp ID (S1030).
Next, the electronic stamp server 300 decrypts the encrypted value which is previously received based on the generated (or obtained) decryption key.
For example, the first electronic stamp server decrypts the eleventh value (or an encrypted eleventh value) based on the generated (or obtained) first decryption key to obtain a twenty first value (or a decoded twenty first value) (S1040).
Next, the electronic stamp server 300 compares the decrypted value with the previously received membership ID to verify (or determine) authenticity of the electronic stamp.
For example, the first electronic stamp server checks whether the twenty first (or the decrypted twenty first) is identical with the membership ID related to the first coffee app which is being executed in the first terminal (S1050).
Next, the electronic stamp server 300 transmits information on the verified (or determined) authenticity of the electronic stamp to the terminal 200. Here, the information on the authenticity of the electronic stamp includes information indicating that the electronic stamp is genuine and information indicating that the electronic stamp is forged.
That is, as a checking result (or a determination result), when the decrypted value is identical with the membership ID, the electronic stamp server 300 verifies that the electronic stamp is genuine to transmit the information indicating that the electronic stamp is genuine to the terminal 200.
Further, as a checking result (or a determination result), when the decrypted value is different from the membership ID, the electronic stamp server 300 verifies that the electronic stamp is forged to transmit the information indicating that the electronic stamp is forged to the terminal 200.
For example, when the twenty first value (or the decrypted twenty first value) is identical with the membership ID related to the first coffee app which is being executed in the first terminal, the first electronic stamp server confirms that the electronic stamp is genuine and transmits the information indicating the electronic stamp is genuine, to the first terminal.
As another example, when the twenty first value (or the decrypted twenty first value) is different from the membership ID related to the first coffee app which is being executed in the first terminal, the first electronic stamp server confirms that the electronic stamp is forged and transmits the information indicating the electronic stamp is forged, to the first terminal (S1060).
Next, the terminal 200 receives information on authenticity of the electronic stamp transmitted from the electronic stamp server 300 in response to the membership ID related to an app which is being executed in the terminal 200 (or a membership ID related to a user of the terminal 200), the electronic stamp information, the encrypted value, and identification information of the terminal 200 which are previously transmitted.
Further, the terminal 200 determines whether to perform a stamp accumulating function (or whether to perform an electronic stamp sealing function) related to the electronic stamp, based on the received information on the authenticity of the electronic stamp.
That is, when it is verified that the electronic stamp is genuine, the terminal 200 performs the stamp accumulating function (or the electronic stamp sealing function) related to the electronic stamp and displays the stamp accumulating function performing result (or the electronic stamp sealing function performing result).
Further, when it is verified that the electronic stamp is forged, the terminal 200 stops the stamp accumulation related to the electronic stamp (or stamp accumulating function/the electronic stamp sealing function) and displays information indicating that the electronic stamp is forged.
For example, the first terminal receives information indicating that the electronic stamp transmitted from a first electronic stamp server is genuine in response to the membership ID related to the first coffee app which is being executed in the first terminal, the electronic stamp information, an eleventh value (or an encrypted eleventh value), and identification information of the first terminal which are previously transmitted, performs the stamp accumulating function of the first coffee app through the electronic stamp based on the received information indicating that the electronic stamp is genuine, and displays a result 810 that the stamp is accumulated through the first coffee app, as illustrated in
As another example, the first terminal receives information indicating that the electronic stamp transmitted from a first electronic stamp server is forged in response to the membership ID related to the first coffee app which is being executed in the first terminal, the electronic stamp information, the eleventh value (or the encrypted eleventh value), and the identification information of the first terminal which are previously transmitted and displays the received information indicating that the electronic stamp is forged through the first coffee app (S1070).
