Digital Rights Management (DRM) system is the effective schemes for digital transactions. A novel authentication scheme of the DRM system based on multimodal biometric verification and watermarking technique is described in this paper, which is based on highly secure iris recognition and face recognition and their feature fusion recognition is described, which is can achieve the rights management of digital content exactly through the illegal user access control. In watermarking algorithm, face image is chosen to be the host image. Iris feature is selected to use as watermark hidden in the host image. Such that iris feature watermark not only protects face biometric data, but also can be used as a covert recognition. Meanwhile, the bimodal biometrics recognition provides the improvement in the accuracy performance of the system.
