With the development of computer and network communication technology, researchers have advanced many image scrambling algorithms to resolve image information security. But how to evaluate the performance of these algorithms has not been studied scientifically. Most of the evaluation ways depend on the original image with large computing work. So it is an important problem to evaluate the image scrambling degree objectively. This paper summarizes the common evaluating parameters, describes their shortcomings and points out the directions about how to evaluate the scrambling degree scientifically further.
