Reversible and Fragile Watermarking for Medical Images [PDF]
Computational and Mathematical Methods in Medicine, 2018 A novel reversible digital watermarking technique for medical images to achieve high level of secrecy, tamper detection, and blind recovery of the original image is proposed. The technique selects some of the pixels from the host image using chaotic key for embedding a chaotically generated watermark. The rest of the pixels are converted to residues by

A reversible database watermarking method non-redundancy shifting-based histogram gaps
International Journal of Distributed Sensor Networks, 2020 In relational databases, embedding watermarks in integer data using traditional histogram shifting method has the problem of large data distortion. To solve this problem, a reversible database watermarking method without redundant shifting distortion is ...
