Fpga Based Image Security and Authentication in Digital Camera Using Invisible Watermarking Technique

For effective digital rights management (DRM) of multimedia in the framework of embedded systems, both watermarking and cryptography are necessary. Here, we present a novel system in the form of a digital camera that embeds biometric data into an image. Incorporation of encryption and watermarking together in the digital camera will assist in protecting and authenticating image files and Watermarking the digital content with origin information or intended recipient identification secures content from electronic data theft. The invisible watermarking algorithm used here allows for verification of the image as well as the identity of the carrier. In this paper, we present an architecture and a hardware efficient FPGA based invisible watermark module towards the development of the complete digital camera.
