Abstract

We describe an digital watermarking algorithm for colour images protection and authenticity: robust, not-blind, wavelet-based. Our algorithm can work with any images, in fact it includes resize techniques that adapt the size of original image for Wavelet transform. The watermark signal is calculated in correlation with the image features and statistic properties. In detection step we apply a re-synchronization between the original and watermarked image according to the Neyman-Pearson statistic criterion. Experimentation on a large set of different images has shown to be resistant against geometric, filtering, and StirMark attacks with a low rate of false alarm. [DOI: 10.1685/CSC06002] About DOI
