In this paper,a new image watermarking algorithm is introduced,which is designed to be robust against print and scan (i.e.slight geometrical distortions and noise).The digital watermark is a square noise-like pattern that is embedded in the Fourier domain and is modulated at a high carrier frequency.Then,several embedding methods are evaluated with respect to their robustness against various distortions.The detection is blind; normalized 2D correlation between the watermark and the Fourier coefficients at the carrier frequency is performed.
