In this paper we investigate the watermarking authentication when applied to medical imagery field. We first give an overview of watermarking technology by paying attention to frag...
—In [1, 2, 3], we have introduced a robust and secure digital signature solution for multimedia content authentication, by integrating content feature extraction, error correctio...
In this paper, a new block-based image-dependent watermarking technique is proposed. The proposed technique utilizes the correlation coefficient statistic to produce a short and un...
We present an efficient JPEG2000-based image authentication scheme, which is robust to JPEG compression and other allowed signal processing operations. Positive wavelet-based wate...
