Abstract

The present invention relates to the authentication system and method which can be utilized as means for person identification and/or commercial payment method using a bar code containing personal information which is created in real-time through a mobile terminal.

The bar code authentication system of the present invention comprises a bar code reader for recognizing and interpreting a bar code created by a mobile terminal, and transmitting bar code recognition information containing the recognition time of the recognized bar code and bar code interpretation information containing the creation time of the interpreted bar code; and a main server for verifying validity of the bar code using the recognition time of the bar code and the creation time of the bar code.

3. The system according to claim 1 or 2, wherein the bar code recognition information further contains location information of the bar code reader.

4. The system according to claim 1 or 2, wherein the said bar code interpretation information further contains personal identification information of the user of the said mobile terminal.

5. The system according to claim 1 or 2, wherein the said verification is determining whether the time difference between the recognition time of the bar code and the creation time of the bar code is smaller than a certain time period.

6. The system according to claim 1 or 2, wherein the said bar code reader includes:

a transmission unit for transmitting the said bar code recognition information and the said bar code interpretation information to the main server through a public switched telephone network or a mobile communication network;

a bar code recognition unit provided with a camera module for recognizing the bar code; and

a bar code interpreting unit for interpreting the recognized bar code.

7. The system according to claim 1 or 2, wherein the said main server transmits a bar code generating program to the mobile terminal after performing person authentication of the user of the mobile terminal.

8. The system according to claim 7, wherein the said bar code generating program encodes and creates a bar code, and the encoded bar code is decoded by the bar code reader or the main server.

9. The system according to claim 8, wherein the mobile terminal stores the bar code generating program into its internal memory or into an external memory.

2. A bar code authentication system comprising:

a bar code reader for recognizing and interpreting a bar code created by a mobile terminal, and verifying validity of the bar code using the recognition time of the recognized bar code and the creation time of the interpreted bar code; and

a main server for receiving and storing bar code recognition information containing the recognition time of the bar code and bar code interpretation information containing the creation time of the bar code.

10. A method of authenticating a bar code comprising:

a first step of allowing a main server to transmit a bar code generating program to a mobile terminal;

a second step of allowing a bar code reader to recognize and interpret a bar code created by the mobile terminal;

a third step of allowing the bar code reader to transmit bar code recognition information containing the recognition time of the recognized bar code and bar code interpretation information containing the creation time of the interpreted bar code to the main server; and

a fourth step of allowing the main server to verify validity of the bar code using the recognition time of the bar code and the creation time of the bar code.

12. The method according to claim 10 or 11, wherein the first step comprises the steps of allowing the main server:

to receive personal identification information of the user of the mobile terminal from the mobile terminal;

to perform person authentication of the user of the mobile terminal using the personal identification information; and

to transmit the bar code generating program to the mobile terminal.

13. The method according to claim 10 or 11, wherein the bar code recognition information further contains location information of the bar code reader.

14. The method according to claim 10 or 11, wherein the bar code interpretation information further contains personal identification information of the user of the mobile terminal.

15. The method according to claim 10 or 11, wherein the verification is determining whether a time difference between the recognition time of the bar code and the creation time of the bar code is smaller than a certain time period.

16. The method according to claim 10 or 11, wherein the bar code recognition of the second step is performed through a camera module of the bar code reader.

17. The method according to claim 10 or 11, wherein the transmission is performed through a public switched telephone network or a mobile communication network.

18. The method according to claim 10 or 11, wherein the bar code generating program encodes and creates a bar code, and the encoded bar code is decoded by the bar code reader or the main server.

19. The method according to claim 18, wherein the mobile terminal stores the bar code generating program into its internal memory or into an external memory.

11. A method of authenticating a bar code comprising:

a first step of allowing a main server to transmit a bar code generating program to a mobile terminal;

a second step of allowing a bar code reader to recognize and interpret a bar code created by the mobile terminal;

a third step of allowing the bar code reader to verify validity of the bar code using a recognition time of the recognized bar code and a creation time of the interpreted bar code; and

20. A bar code authentication system comprising:

a bar code reader for recognizing and interpreting a bar code containing personal identification information and OTP code information created by a mobile terminal, and transmitting the personal identification information and the OTP code information; and

a main server for creating confirmative OTP code information using a private key corresponding to the personal identification information and time information when the transmitted OTP code information was created, the time being contained in the transmitted OTP code information, and determining authenticity of the transmitted OTP code information by comparing the created confirmative OTP code information with the transmitted OTP code information.

22. The system according to claim 20 or 21, wherein the mobile terminal has a private key that is the same as the private key of the bar code reader, creates the OTP code information using its private key, the personal identification information, and current time information, and adds the created OTP code information into the bar code.

23. The system according to claim 22, wherein the mobile terminal stores an OTP code generating program for creating the OTP code information, a bar code generating program for creating the bar code, and the private key into its internal memory or into an external memory.
