Intensifying the Security of Multiomodal Biometric Authentication System using Watermarking

Аннотация

In Multimodal biometrics system two or more biometric attributes are combined which makes it far more secure than unimodal system as it nullifies all the vulnerabilities of it But with the prompt ontogenesis of information technology even the biometric data is not secure There is one such technique that is implemented to secure the biometric data from inadvertent or deliberate attacks is known as Digital watermarking This paper postulate an approach that is devise in both the directions of enlarging the security through watermarking technique and improving the efficiency of biometric identification system by going multimodal Three biometric traits are consider in this paper two of them are physical traits i e face fingerprint and one is behavioral trait signature The biometric traits are initially metamorphose using Discrete Wavelet and Discrete Cosine Transformation and then watermarked using Singular Value Decomposition Scheme depiction and presented results rationalize the effectiveness of the scheme
