Performance Analysis of DWT Based Video Watermarking Algorithm on FPGA

Digital video watermarking was introduced at the end of the last century to provide means of enforcing video copyright protection. Video watermarking involves embedding secret information (data) in the video. Here Discrete Wavelet Transform (DWT) to authenticate the multimedia image and LSB algorithm to insert the bits of the hidden message or image into the least significant bits of the pixels.Xilinx Spartan3 Field Programmable Gate Array (FPGA) device using embedded development kit (EDK) tools from Xilinx used to implement the presented algorithm. To check effectiveness of this technique for Imperceptibility and robustness PSNR and NCC parameters are calculated by adding different attacks. To improve performance DWT-DCT algorithm are implemented using MATLAB software.
