A new digital watermarking model using honey encryption and reversible cellular automata [PDF]

Scientific Reports
Watermarking is the process of embedding and extracting a watermark design on a digital cover to prove the image’s copyright or ownership, thereby securing the image’s authenticity. The proposed method in this paper uses a combination of honey encryption

Reversible watermarking scheme with image-independent embedding capacity [PDF]

, 2005
Permanent distortion is one of the main drawbacks of all the irreversible watermarking schemes. Attempts to recover the original signal after the signal passing the authentication process are being made starting just a few years ago. Some common problems,

A contrast-sensitive reversible visible image watermarking technique [PDF]

, 2009
A reversible (also called lossless, distortion-free, or invertible) visible watermarking scheme is proposed to satisfy the applications, in which the visible watermark is expected to combat copyright piracy but can be removed to losslessly recover the ...

Integer DCT based reversible image watermarking by adaptive coefficient modification

, 2022
S.218-229We investigate in this paper several possible methods to improve the performance of the bit-shifting operation based reversible image watermarking algorithm in the integer DCT domain. In view of the large distortion caused by the modification of

An Adaptive Reversible Image Watermarking Scheme Based on Integer Wavelet Coefficients [PDF]

, 2013
This paper presents an integer wavelet coefficients based reversible image watermarking scheme. A reversible image watermarking approach extracts the embedded watermarks from a watermarked image and recovers the watermarked image to the original image ...
