Watermarking d'images par paquets d'ondelettes

Abstract : The aim of this work is to present and investigate a new method for the watermarking of images. It is based on a modification of the wavelets packets decomposition of the data. The principle is to alter the coefficients in such a way that a given secret subset of the best basis satisfies some constraints, which constitute the watermark. In this sense, the mark is a virtual one. Some preliminary results are presented.
