Compare different techniques to retrieve image from database using MATLAB

Newly World Wide Web technologies, there is need to secure data. For securing data cryptography and other relevant techniques were introduced. Multimedia stream, traditional textual based encryption schemes are not successful so develop new schemes. During transmission storage over a network, multimedia content such as digital images information vulnerable unauthorized access. The used may be gray or color scale images. There many measures for testing image quality, like the mean structural similarity, absolute error, Mean Square Error (MSE), Peak Signal-to-Noise Ratio (PSNR). These computed by averaging squared intensity differences of distorted original pixels, along with related quantity PSNR. Results experiments show that same size efficiently encrypted reliable maximum PSNR compared different MATLAB2013a simulation purpose. As refereed results, proposed system only shows efficiency in hiding attributes but also provides better cover selection.
