Biometric Authentication System

This paper covers the field of biometric systems focus on biometric authentication systems. A short and general overview of biometric authentication systems gives some insight in how the various biometric data can be used for authentication. The problems of varying biometric data, caused by noise respectively human nature and approaches to solve these problems with multi-biometric systems in combination with information fusion, are also discussed. Since there is such a vast range of variances for the usage of biometric systems, some type of statistics is determined.
