A novel copyright protection scheme for digital images based on visual cryptography and statistics is proposed. The proposed method employs sampling distribution of means and visual cryptography to achieve the requirements of robustness and security. Our method can register multiple secret images without altering the host image and can identify the rightful ownership without resorting to the original...

A novel adaptive imperceptible video watermarking based on the model of entropy is proposed. By combining the human visual masking system (HVS) with the blocking-matching techniques acquire the motion information in video sequence. The statistics to the motion information in every macro-block could be gotten by using the model of entropy. According to the entropy of motion information of every macro-block...
