Abstract — The objective of this work is to develop a hardware-based watermarking system to identify the device using which the photograph was taken. The watermark chip will be fit in any electronic component that acquires the images, which are then watermarked in real time while capturing along with separate key. Watermarking is the process of embedding the watermark, in which a watermark is inserted in to a host image while extracting the watermark the watermark is pulled out of the image. The ultimate objective of the research presented in this paper is to develop low-power, high-performance, real-time, reliable and secure watermarking systems, which can be achieved through hardware implementations. In this paper the development of a very Large Scale Integration (VLSI) architecture for a high-performance watermarking chip that can perform invisible colour image watermarking using genetic algorithm is discussed. The prototyped VLSI implementation of watermarking is analyzed in two ways.
