Exchange of large amount of multimedia data have become feasible with the explosive growth of internet technology. People can easily copy and modify the digital product which leads to the piracy problems which is spreading over the internet and thus poses a great threat to the ownership rights. Digital Right Management (DMR) has emerged to raise the issues regarding intellectual property rights. In this paper, a two tier protection mechanism has been proposed that uses both cryptography and robust watermarking simultaneously to provide effective protection mechanism for DMR. In this the binary information is kept hidden in the color image using a secret key by firstly converting into a scrambled code that can be securely extracted and authenticated. Compare the two images to access its quality and to check if the quality needs improvement. Also to check if the proposed method can survive under various intentional or unintentional attacks.
