Content-Dependent Image Watermarking using Local Gray Level Co-occurrence Matrix Texture Features

Abstract

In this paper, we present a watermarking scheme in which the watermark pattern depends on the content of the image into which it is embedded. This scheme is aimed at preventing operations in which an attacker copies a legitimate watermark and embedded into another image. The content dependency is achieved by modifying the watermark payload with the host image hash. The image hash is constructed using local Gray Level Co-occurrence Matrix (GLCM) texture features. The watermarking scheme used in this paper is the Direct-Sequence Code Division Multiple Access scheme. Our experiments show that the proposed content-dependent watermarking scheme can resist watermark copying, giving watermark BER of 49.25% when a watermark pattern copied onto another image is detected using a correct key
