A strong sensitivity of digital image watermarking scheme for noise disturbance

Through this paper, a strong sensitivity of digital image watermarking scheme for noise disturbance is proposed. The scheme is based on the singular value decomposition (SVD) method by the texture masking in accordance with the human visual system (HVS) characteristics. Two main steps of the proposed scheme are composed of calculating the weighted value of enhanced noise sensitivity by the texture masking model to obtain the strong sensitivity and modifying the singular value of host image and the singular value of watermark by the SVD method operation. With a little disturbance to the image provided, the singular value of an Image will have a good stability and does not change significantly. The experiment results show the improved performance of the proposed scheme against a type attack of salt peppers noise in comparison with the pure texture masking scheme and an existing scheme.
