Additive Block Coding Schemes for Biometric Authentication with the DNA Data

Abstract

To implement a biometric authentication scheme, the templates of a group of people are stored in the database (DB) under the names of these people. Some person presents a name, and the scheme compares the template of this person and the template associated with the claimed person to accept or reject their identity [1]. The templates of people stored in the DB should be protected against attacks for discovery the biometrics and attacks for successful passing through the verification test. The authentication algorithm developed by Juels and Wattenberg [2] is a possible solution to the problem. However, implementations of this algorithm for practical data require generalized versions of the algorithm and their analysis. We introduce a mathematical model for DNA measurements and present such a generalization. Some numerical results illustrate the correction of errors for the DNA measurements of a legitimate user and protection of templates against attacks for successful passing the verification stage by an attacker.
