Digital watermarking is a core technology for the copyright protection of multimedia digital content circulated on the Internet. A web based watermarking technique is proposed to embed watermark text, watermark image and a digital signature into the image. An immense amount of study has gone into crafting an algorithm for creating and inserting watermarks into a digital image. The proposed algorithm offer added controls to image proprietors by integrating benefits of using Internet to the watermark scheme. Experimental results prove that our projected watermarking technique provides steady protection to the ownership rights, gives good image quality and are robust in varying degree to JPEG compression and low-pass filtering. The application compresses the images to nearly 50%, decrease the computation time, reduces the web server space (to nearly 33.7%) and the image so created displays clear watermark on the image for immediate claim of ownership and authorship.
