Zero watermarking algorithm based on revised histogram invariant moments

A zero watermarking algorithm based on revised histogram invariant moments to resist geometric attacks was proposed in order to reduce the probability of dis-detectes and leak-detecting of zero watermarking.This algorithm calculates histogram invariant moments of original image and uses the histogram to construct zero watermarking system.The histogram invariant moments of test image is corrected by correlation coefficient of two images.The detection of watermarking system is achieved by calculating the revised histogram invariant moments.Simulation experiments demonstrated that watermarking detection was simple,had low dis-detecting rate and false alarm rate.The robust of proposed method is better than that of traditional histogram invariant moments in common signal processing and geometric attacks.
