Abstract: User authentication is essential to provide security that restricts access to system and data resources. Biometric system refers to an recognition of legitimate user based on a feature vector(s) derived from their distinguishing behavioral and/or physiological traits like face, finger, speech iris, gait, etc., Research on biometrics has distinctly increased for solving identification and authentication issues in forensics, physical and computer security , custom and immigration, However, unimodal biometric system is not able to satisfy acceptability, speed, and reliability constraints of authentication in real applications due to noise in sensed data, spoof attacks, data quality, lack of distinctiveness, restricted degree of freedom, non-universality and other factors. Therefore multimodal biometric systems are used to increase security as well as better performance. This paper presents overview of different multimodal biometric (multibiometric) systems and their fusion techniques with respective their performance
