Implementation of real time digital watermarking system for video authentication using FPGA

This paper presents a hardware implementation of a digital watermarking system that can insert invisible, semi fragile watermark information into compressed video streams in real time. The watermark embedding is processed in the discrete cosine transform domain. Hardware implementation using field programmable gate array has been done, and project was carried out using a custom versatile breadboard for overall performance evaluation which become a viable target for the implementation of real time algorithms suited to video image processing applications. This System is developed on Xilinx Spartan3 Field Programmable Gate Array (FPGA) device using embedded development kit (EDK) tools from Xilinx. The results showed that the proposed algorithm has a very good hidden invisibility, good security and robustness for a lot of hidden attacks.
