Abstract:
Digital watermarking is a technique of embedding some information into the given media, which can be later extracted or detected for variety of purposes. The data embedded is called as watermark and the given media is called as host or cover media. A web-based image transmission system using digital watermark is presented with experimental results in this paper.
This system assures when pirated image is found, the illegal user can be traced. The user’s message after chaotic encryption as watermark embeds into image. Experimental results show our system which is used for a web-based image transmission is effective and robust. Especially, user’s message can also be extracted from watermark image under diverse attacks such as some image-processing operations and JPEG compression.
Existing system:
• A user can pay for obtaining on-line image from a product provider (PP).
• However, unprotected image can be easily pirated by some users, while the user may leak the image to illegal user.
• Ever if a pirated image has been found, it is almost impossible to identify which user has pirated the image.
Proposed system:
• This system assures when pirated image is found, the illegal user can be traced. The user’s message after chaotic encryption as watermark embeds into image.
• Experimental results show our system which is used for a web-based image transmission is effective and robust.
• Especially, user’s message can also be extracted from watermark image under diverse attacks such as some image-processing operations and JPEG compression.
• The image transmission system based on watermark resolves the defect of conventional watermark image.
• In this system, users’ privacy message can be embedded image in order to obtain trace of output images.
• The system’s target is when pirated image is found, we can extract watermark from image to identify which user pirates image.
