AN OVER LOOK– VARIOUS APPROACHES FOR RECOGNITION

Abstract In this paper, we analyze enhancing the Security and Privacy of multimodal biometric system. Comparing with the traditional authentication technology(password, ID, keys, etc), biometric recognition technology make users not to remember password and take keys and therefore to avoid some problems such as forgetting password, losing keys and potential secure problem etc. Biometric recognition technology operates simply, so users can finish identification without special skills and action. As a result biometric recognition technology has drawn more and more attention as a replacement of traditional authentication technology. Recently biometric recognition technology has widely development and application in various fields. However, with the development of technology the traditional, unimodal biometric system performance could not satisfy people's request of security. Multimodal biometric technology is to do identification by using two or more human physical characteristics or behavior characteristics. This paper presents the review of multimodal biometrics. This includes applications, challenges and areas of research in multimodal biometrics. The different fusion techniques of multimodal biometrics have been discussed.
