Authentication method and authentication apparatus using synthesized code for iris
First Claim
Patent Images
1. An authentication method, comprising:
- obtaining iris images;
constituting an enroll set including iris codes and mask codes corresponding to the iris images; and
generating a synthesized code including a synthesized iris code and a synthesized mask code based on correlations between the iris codes included in the enroll set in block units;
wherein the generating of the synthesized code comprises;
calculating the correlations between the iris codes in the block units; and
determining, for each block position of the iris codes, the synthesized iris code and the synthesized mask code based on correlations with blocks that respectively correspond to different iris image positions.

15. An authentication apparatus, comprising:
-
a sensor configured to photograph iris images; and a processor configured to constitute an enroll set including iris codes and mask codes corresponding to the iris images, and generate a synthesized code including a synthesized iris code and a synthesized mask code based on correlations between the iris codes included in the enroll set in block units;
wherein the processor is configured to calculate the correlations between the iris codes in the block units, and generate the synthesized code by determining, for each block position of the iris codes, the synthesized iris code and the synthesized mask code based on correlations with blocks that respectively correspond to different iris image positions. - View Dependent Claims (17, 18, 19)
