A study on accuracy in biometrics person authentication using error correcting codes application to speaker collation system

摘要

Biometrics person authentication has been considered one of key technologies for identity verification in networked world. Accuracy of biometrics is influenced by several factors, such as changes of environments to input biometric parameters, which is caused by using different kinds of sensors or distortions of biometric parameters and so on. In this paper, we propose the method to solve these matters using error correcting codes, where we consider that changes of biometric parameters are similar to bit errors in transmission systems. We describe effects of the proposed method with simulation results on a speaker verification method.
