System and Method for Authentication Using a Bar-Code
First Claim
1. A bar code authentication system comprising:
- 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.

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.

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. - View Dependent Claims (22, 23)
