Digital image scrambling can change histogram distribution of original image,It plays an important role in the image encryption.Research of grayscale scrambling effect in the field of information hiding has important significance.The existing evaluation algorithm is analyzed based on histogram similarity degree,finds out the deficiency, proposes reasonable grayscale scrambling basis for evaluation,and further proposes further new evaluation algorithm of grayscale scrambling evenness.
