Web Document Protection Technique Using Unicode

Today internet access has enabled the wide spread of digital multimedia contents in the form of text, image, video and audio; however, it also makes unauthorized copying and distribution easier. Watermarking, as a eventual weapon against piracy, embeds ownership information into the host contents without degrading the perceptual quality of these contents. To preserve quality of content text watermarking is essential. The text watermarking is one of the most effective method for digital document protection. An implementation of text watermarking for the web document can detract the invisibility and robustness of embedded watermark. This problem can be solved by using unicode based web document protection technique. This technique is comprised of three processes like generation of watermark, embedding watermark and detection of watermark from web document with some different approach than the traditional one.
