Abstract: Due to rapid growth in use of networked multimedia system created need for copyright protection of digital media like image, video, audio. The watermarking techniques used to solve the problem of protecting digital media. This paper implements digital watermarking by inserting invisible watermark into compressed video stream in real time on an FPGA platform. The watermark is embedded using Haar wavelet Transformation and least significant bits algorithm. The idea behind the least significant bits algorithm is to insert the bits of the secret information into the least significant bits of the pixels. This algorithm helps to replace the random noise by using the lowest bits where secret information is inserted to avoid noise and attacks. The results indicate that the proposed algorithm has a very good hidden invisibility, good security and robustness for hidden attacks.
