摘    要:The purpose of digital image scrambling is to transforn a given digital image into a rather scrambled one so as to make it difficult for other people to find out the true meaning of the scrambled image. This paper comes up with a certain number of approaches to scrambling digital images, which, when thus processed, cannot be reconstructed in a common way. As a result, the original image is enc yrypted and protected.
