A lot of research has been done on biometrics. In this paper, the authors represent the brief survey on biometrics and its modalities. It consists of the comparison between the parameters that have been used in the proposed work life face, finger prints and speech. In the paper, the survey is followed as a consequence and specifies the strong technique using finger, face and speech. To overwhelm the weakness of the unimodal biometric techniques, there is destitution of multimodal biometric techniques.
