FPGA prototype of visual information hiding

The current explosion of digital media creates threats towards the security in multimedia data broadcasting. Watermarking technique becomes a prospective solution to this coercion by means of Intellectual Property Right Protection, Authentication and Integrity Verification of digital media. In this paper we introduce an approach that enables us to develop a low power, real time, reliable and secure data hiding system. As an effort towards the power efficient system, here we present an oblivious, spatial domain watermarking based authentication algorithm and its FPGA implementation. The low cost data embedding algorithm can hide watermark into original cover image coming from a sensor much faster than software implementation and the embedded image is easily transmitted to PC by using appropriate interface.
