An adaptive reversible watermarking in IWT domain
Multimedia Tools and Applications, 2020An adaptive reversible watermarking in integer wavelet transform (IWT) domain was proposed in this paper. It could adaptively embed according to the size of the watermark, achieve blind extraction, and the extracted image was completely lossless. A new method of embedding watermark into diagonal components based on the relationship between adjacent ...

Improved Capacity Reversible Watermarking
2007 IEEE International Conference on Image Processing, 2007This paper continues our researches on high capacity reversible watermarking based on simple transforms. Image pixels obeying some simple constraints are transformed and then, data is embedded by simple additions. The transform induces a congruence equation.

An improved mechanism for reversible watermarking of images
SPIE Proceedings, 2013Reversible watermarking algorithms allow extraction of the hidden information to ensure authenticity and restore original medium. Prediction-error expansion (PEE) methods give high payload with little or no visible distortion. In these methods performance of the algorithm relies heavily on predictor`s response.

Prediction-error based reversible watermarking
2004 International Conference on Image Processing, 2004. ICIP '04., 2005Reversible watermarking has become a highly desirable subset of fragile watermarking for sensitive digital imagery in application domains such as military and medical because of the ability to embed data with zero loss of host information. This reversibility enables the recovery of the original host content upon verification of the authenticity of the ...

Reversible Watermarking Techniques
2021Digital content security gained immense attention over past two decades due rapid digitization of industries and government sectors, and providing security to digital content became a vital challenge. Digital watermarking is one prominent solution to protect digital content from tamper detection and content authentication. However, digital watermarking

Circular interpretation of histogram for reversible watermarking
2001 IEEE Fourth Workshop on Multimedia Signal Processing (Cat. No.01TH8564), 2002The need for reversible or lossless watermarking methods has been highlighted to associate information with losslessly processed media or to enable their authentication. The paper first analyzes the specificity and the application scope of lossless watermarking methods.

Reversible Watermarking Surviving JPEG Compression
2005 IEEE Engineering in Medicine and Biology 27th Annual Conference, 2005This paper will discuss the properties of watermarking medical images. We will also discuss the possibility of such images being compressed by JPEG and give an overview of JPEG compression. We will then propose a watermarking scheme that is reversible and robust to JPEG compression.

Structuring Element for Secure Reversible Watermarking
2020 International Conference on Multimedia Analysis and Pattern Recognition (MAPR), 2020The ability to embed data into image with reversibility would allow host image can be restored from modification in embedding task. Structuring elements provided an information-rich link of host image before and after embedding data that could be important in the development of new way of exploring secure competence.

Reversible Semi-Fragile Authentication Watermark
Multimedia and Expo, 2007 IEEE International Conference on, 2007Reversible semi-fragile authentication watermark (RSAW) is required in an integrated and powerful authentication system. An effective RSAW scheme should have the desirable features: tamper detection and localization, good perceptual invisibility, detection without requiring explicit knowledge of the original image, robustness against lossy compression,

Reliable embedding for robust reversible watermarking
Proceedings of the Second International Conference on Internet Multimedia Computing and Service, 2010It has been demonstrated that De. Vleeschouwer's histogram rotation (HR) scheme suffers from serious "salt-and-pepper" noise in the watermarked images. Recently, some improved methods are proposed to handle this problem. However they are at the cost of capacity.
