Differential Histogram Modification-Based Reversible Watermarking with Predicted Error Compensation

Reversible watermarking inserts watermark into digital media in such a way that visual transparency is preserved and the original media can be restored from the marked one without any loss of media quality. High capacity and high visual quality are a major requirement for reversible watermarking. In this paper, we present a novel reversible watermarking scheme that embeds message bits by modifying the differential histogram of adjacent pixels. Also, overflow and underflow problem is prevented with the proposed predicted error compensation scheme. Through experiments on various images, we prove that the presented scheme achieves 100% reversibility, high capacity, and high visual quality over other methods, while maintaining the induced-distortion low.
