Abstract

Automatic person authentication is an important task in our day to day life. Earlier method of establishing a person’s Authenticate includes knowledge based like password or token base like id cards. These identities may be lost stolen or shared by any person .For these reasons they are not suitable for authentication.

A multimodal biometric system combines two or more features of a person to be recognized together to determine a person’s authentication. This paper discusses types of Biometrics, Characteristics, level of fusion and Challenges and Research area etc.
