Digital watermarking for image using FELICS algorithm in VLSI implementation

This paper presents a hardware implementation of a digital watermarking system that can insert invisible and visible watermark information into compressed image streams in real time application. A Watermarking technique is a process of embedding information in multimedia contents to prove identification and authentication. This technology embeds a data, an imperceptible digital code, namely the watermark, which carry information about the copyright status of the work to be protected. Continuous efforts are being made to device an efficient watermarking schema but the techniques discrete cosine transform domain proposed so far do not seem to be robust to all possible attacks and multimedia data processing operations. A new watermarking and Fast Efficient Lossless JPEG Image Compression scheme is proposed to optimize security, copyright, authentication and compression rate when watermarks are embedded into JPEG 2000 compressed images.
