Multimodal Biometric Watermarking Techniques: A Review

Abstract

Multimodal biometric systems are being gradually deployed in much large scale biometric applications because they have several advantages such as lower error rates and larger population coverage compared to unibiometric systems. A number of watermarking algorithms have been proposed, they have limited real-world applicability due to the balance between credit performance and security of the template. In this paper, a universal evaluation of the main literature related to the Bio watermarking is presented together with classification by using a variety of techniques.
