A Novel Correlation Detection System for Multiplicative Robust Watermarking

Watermarking technique is popular of the solution to copyright protection. Good detection method can improve the probability of the successful detection. In this paper, a novel blind detection method pointing to the multiplicative embedding rule is proposed. Whether the watermark is present in the received image or not is determined by the correlation between the transform coefficients with the watermark and the possible watermark. Experimental results prove that the proposed detection method is robust against the signal processing operations, such as JPEG compression, lowpass and median filtering, dithering, Gaussian noise etc., and several geometrical attacks such as resizing and cropping.
