Patent Images
1. An apparatus for generating biometric information, the apparatus comprising:
- a biometric scanning module configured to scan a body of a user to generate biometric image information;
a seed supplying module configured to supply a secure seed having a security that is effective for a preset time period and valid for a one-time use;
a security pattern generating module configured to generate a secure watermark pattern based on the secure seed; and
a biometric information generating module configured to generate biometric information to be used for authentication by the use of the biometric image information and the secure watermark pattern.

7. An apparatus for authenticating biometric information, the apparatus comprising:
-
a seed generating module configured to generate a secure seed having a security that is effective for a preset time period and valid for a one-time use; a secure pattern verifying module configured to perform a primary authentication on biometric information to be used for authentication when the biometric information includes a secure watermark pattern that is generated based on the secure seed; a biometric information storage module configured to store reference biometric information to be used for an authentication procedure; and a biometric authenticating module configured to perform a secondary authentication depending on a result of comparison between the biometric information and the reference biometric information when the primary authentication has been performed. - View Dependent Claims (8, 9, 10)
