This technique is better than Digital Signature and other methods because it does not increase overhead. Digital Watermarking is not an older Field. There are manyresearch are going in this field. Researchers have invented technique those increase the Security, Capacity and Imperceptibility of Watermarked Images. Here, in this Thesis our main focus is on providing robustness for web applications i.e. we provide the security to images those are stored in remote server so that unauthorized customer will not receive the image from server becausethe image is watermarked by using the Algorithm described in this research work and if the customer will hack the image then he / she will get the distorted image.
