JPEG image encryption aims at effectively converting the original into a noise-like that does not contain any useful information of image. Existing schemes for encryption, however, may attain good balance in terms file size increment and security. To address problem, we design novel scheme. Different from existing schemes, first predict DC coefficients by an adaptive prediction method. Subsequently, histogram coefficient errors is encrypted combining random integers to reduce encoded length,...
