Biometric Based User Authentication and Data Encryption
First Claim
Patent Images
1. A method securely storing biometric parameters in a database, comprising:
- encoding enrollment biometric parameters of a user using a syndrome encoder to produce an enrollment syndrome vector;
applying a hash function to the enrollment biometric parameters to produce an enrollment hash; and
storing the enrollment syndrome vector and the enrollment hash in a database.

Abstract
Biometric parameters acquired from human forces, voices, fingerprints, and irises are used for user authentication and access control. Because the biometric parameters are continuous and vary from one reading to the next, syndrome codes are applied to determine biometric syndrome vectors. The biometric syndrome vectors can be stored securely while tolerating an inherent variability of biometric data. The stored biometric syndrome vector is decoded during user authentication using biometric parameters acquired at that time. The syndrome codes can also be used to encrypt and decrypt data.
