Abstract. In this paper, we propose a watermarking scheme for the image ownership verification in terms of a private key pattern and wavelet filters. The watermarking is mainly ach...

In this paper, we propose a new public key watermarking scheme for reversible image authentication where if the image is authentic, the distortion due to embedding can be complete...

An approach to embedding gray scale images using a discrete wavelet transform is proposed. The proposed scheme enables using signature images that could be as much as 25% of the h...

A possible solution to the difficult problem of geometrical distortion of watermarked images in a blind watermarking scenario is to use a template grid in the autocorrelation func...
