A New Card Authentication Scheme Based on Image Watermarking and Encryption

With smart card’s vast use, the security is becoming more and more important. Traditional password authentication can’t meet user requirements. Many user’s authentication schemes have been proposed, especially, based on image encryption. However, most existing schemes have problems of single authentication mode, low encryption intensity and poor quality of restored image. In this paper, we propose a dual authentication scheme using fingerprint biometric modality and digital watermarking techniques. Experimental results show that our dual authentication scheme is of more security, efficiency and low storage cost.
