Multimedia is the ruler of the digital era and here data storage and transmission is of utmost importance. Data transmission is the prime focus of the Information industry. And how to ensure this safely has become a crucial issue. This brings in the need for protection of data in other words, privacy. As a user, protection against misuse of private information is essential and hence several encryption strategies have evolved. In the proposed scheme, image encryption using various strategies in order to improve the rate of security has been adopted. The methods involved are row and column shuffling, indexing, swapping, wavelet transforms and watermarking. Stego involves hiding a message in a stego medium whereas water marking is used to prove one's copyright protection. The resultant crypto image data is highly secure and it improves the imperceptibility of the encrypted image.
