Abstract: “In recent years, the applications about multimedia have been developed rapidly. Digital media brings about conveniences to the people, because it is easy to be processed. At the same time, it enables the illegal attackers to attack the works. For the protection of data, there has been growing interest in developing effective techniques to discourage the unauthorized duplication of digital data. Digital watermarking is the process of embedding information into a digital signal in a way that is difficult to remove. The ultimate objective of the research presented in this paper was to develop low-power, high- performance, real-time, reliable and secure watermarking systems, which can be achieved through hardware implementations. In this paper, we present a review of FPGA based implementation of watermarking encoder and decoder.”
