Method and system combining cryptographic key/seed with iris biometrics for enhanced security

摘要

The present invention relates to a method and system for generating a security key using iris recognition, and more particularly, in order to strengthen security, a user's iris template and a key/seed required for encryption are combined and encrypted, and a security key is finally generated from this. It relates to a method and system. A method of generating a security key using iris recognition according to an embodiment of the present invention includes the steps of acquiring a first iris image by photographing a user's iris, analyzing a first iris pattern included in the first iris image, and converting the first iris pattern into a digital template to generate a first iris template; performing encoding for encoding and compressing a user's private key/seed; the encoded private key/seed The steps of generating a security key by combining the seed and the first iris template, acquiring a second iris image by photographing the user's iris, analyzing the second iris pattern included in the second iris image, and now 2 converting the iris pattern into a digital template to generate a second iris template, and extracting a private key/seed from the security key using the second iris template.
