Tamper detection with self-correction hybrid spatial-DCT domains image authentication technique
Abstract:The development of effective image authentication techniques is of remarkably growing interest. Some recently developed fragile, semi-fragile/robust or hybrid-watermarking algorithms not only verify the authenticity of the watermarked image but also provide self-reconstruction capabilities. However, several algorithms have been reported as vulnerable to various attacks, especially blind pattern matching attacks with insufficient security. In this paper, we propose a new blind dual-domain selfembedding watermar… Show more
