A Novel Hybrid Reversible-Zero Watermarking Scheme to Protect Medical Image
IEEE Access, 2022 The verification of copyright and authenticity for medical images is critical in telemedical applications. Watermarking is a key technique for protecting medical images and can be mainly divided into three categories: region of interest (ROI) lossless ...

Reversible Watermarking Using Statistical Information [PDF]
EURASIP Journal on Advances in Signal Processing, 2010 In most reversible watermarking methods, a compressed location map is exploited in order to ensure reversibility. Besides, in some methods, a header containing critical information is appended to the payload for the extraction and recovery process.

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
