Abstract

An NFC tag-based Web service method based on an anti-simulation function includes a first operation of transmitting a response including URL information to the NFC reader when the NFC tag recognizes tagging of the NFC reader, and a second operation of receiving the URL information, by the Web server, the URL information from the mobile Internet device, and transmitting Web page information corresponding to the URL information to the mobile Internet device, wherein the URL information provided by the NFC tag to the NFC reader is varied URL information including a key changed and generated whenever tagging occurs, and the key is changed and generated according to a generation algorithm shared with the Web server.

Claims

1. An NFC tag-based Web service method based on an anti-simulation function, providing a Web service on the basis of an NFC tag using an NFC tag, a mobile Internet device including an NFC reader, and a Web server providing a Web service to the mobile Internet device, the method comprising:

a first operation of transmitting a response including URL information to the NFC reader when the NFC tag recognizes tagging of the NFC reader; and

a second operation of receiving the URL information, by the Web server, the URL information from the mobile Internet device, and transmitting Web page information corresponding to the URL information to the mobile Internet device,

wherein the URL information provided by the NFC tag to the NFC reader is varied URL information including a key changed and generated whenever tagging occurs, and the key is changed and generated according to a generation algorithm shared with the Web server.

2. The NFC tag-based Web service method of claim 1, wherein

the key is a counter value increased or decreased cooperatively according to tagging or a calculation value using at least the counter value as an input.

3. The NFC tag-based Web service method of claim 1, wherein

the key is an OTP value or a calculation value using at least the OTP value as an input.

4. The NFC tag-based Web service method of claim 1, wherein

the first operation comprises:

(1-1)th operation of generating the key after receiving a request from the NFC reader; and

(1-2)th operation of generating the varied URL information by inserting the key generated in (1-1)th operation into fixed URL information stored as a fixed value in the NFC tag or replacing a portion of the fixed URL information with the key generated in the (1-1)th operation.

5. The NFC tag-based Web service method of claim 1, wherein

the second operation comprises:

(2-1)th operation of extracting a key from the varied URL information, after receiving the varied URL information from the mobile Internet device;

(2-2)th operation of verifying validity of the extracted key according to the shared generation algorithm; and

(2-3)th operation of approving provision of a Web service to the mobile Internet device when the extracted key is a normal key according to the validity verification result.

6. The NFC tag-based Web service method of claim 5, further comprising:

(2-4)th operation of not approving provision of a Web service to the mobile Internet device, when the extracted key is an abnormal key according to the validity verification result.

10. The NFC tag-based Web service system of claim 1, wherein

the key is included in a parameter area of a URL.

11. The NFC tag-based Web service system of claim 1, wherein

the key is included in a directory or a file name of a URL.

7. An NFC tag-based Web service system having an anti-simulation function, comprising:

an NFC tag providing URL information to an NFC reader installed in a mobile Internet device when the NFC reader tags; and

a Web server receiving the URL information from the mobile Internet device and providing a Web service to the mobile Internet device,

wherein the URL information provided by the NFC tag to the NFC reader is varied URL information changed and generated whenever tagging occurs, and the key is changed and generated according to a generation algorithm shared with the Web server.

8. The NFC tag-based Web service system of claim 7, wherein

the NFC tag comprises:

a first key generator generating a counter value increased or decreased cooperatively according to the tagging, a calculation value using at least the counter value as an input, an OTP value interworking with time at the time of the tagging, or a calculation value using at least the OTP value as an input, as the key; and

a modifier generating the varied URL information by inserting a key generated by the first key generator into fixed URL information stored as a fixed value in the NFC tag or replacing a portion of the fixed URL information with the generated key.

9. The NFC tag-based Web service system of claim 7, wherein

the Web server comprises:

a second key generator generating a key by itself according to the shared generation algorithm;

an inspector verifying validity of a key included in the varied URL information received from the mobile Internet device, in cooperation with the second key generator; and

a WAS providing a Web service to the mobile Internet device when the key included in the varied URL information is a normal key according to the validity verification result.

12. The NFC tag-based Web service system of claim 7, wherein

the key is included in a parameter area of a URL.
