Image Watermarking for Tamper Detection and Content Recovery Applications Based on a Preservative Bi-Level Moment Approach with Shuffling

Abstract

In this paper, a modified color image watermarking is presented to be used for tamper detection and content recovery applications. The proposed technique is based on the bi-level moment-preserving approach where the developed technique maps the image blocks using a shuffling approach to improve resistance to attacks. Simulations have shown that the proposed technique exhibits better performance when compared to the classical bi-level moment-preserving technique in terms of the watermarking imperceptibility and recovery quality.
