%X This paper proposed a method for evaluating image scrambling effect through the way of block processing. After processing the initial and encrypted images with the same block size, Bhattacharyya coefficients between the initial and encrypted image probability distributions were calculated, and then treating the average value of all blocks as the scrambling degree of the scrambling transformation.New method was simple and the meaning was clean.Experimental results show that the method can reflect the scrambling degree under different scrambling transformation.
