Due to the development of high speed internet and multimedia technology digital documents can be distributed through World Wide Web to large number of people. It brings severe problem, so that protection of multimedia information must require. In the digital world, images are available in a variety of formats. They are easy to copy and resell. Usually media data is handled in compressed and encrypted form and it is an essential to watermark this form of data for security purpose. This technique is used to survive attacks from potentialhackers and also providing information about the original owner. In existing system, sometimes senderinsert watermark by using the reformation of bits. So, the image quality is decreased as well as if some changes in the bits at the time of compression and also encryption process, there is large variance in the image quality. To overcome this problem, in the proposed system the image is first compressed and then encrypted and finally it is watermarked to maintain a quality of image. Rational dither modulation is an efficient method of watermarking which providesrobustness against amplitude scaling attacks and minimizes Bit Error Rate. It is an alternative to Quantization Index Modulation.
