Blind watermarking algorithm based on general Gaussian model

This paper presents an image digital watermarking algorithm in the block-wise DCT domain. The algorithm is designed based on the general Gaussian model, the special case of which can be the Gaussian model or the Laplacian model. The detection does not need the original images and is independence of the actual image. The result of experiment shows the algorithm to be secure against the JPEG compression attack, cropping attack and some other attacks.
