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 of 2D-vector data
Proceedings of the 2004 workshop on Multimedia and security, 2004This paper presents a reversible watermarking scheme for the 2D-vector data (point coordinates) which are popularly used in geographical information related applications. This reversible watermarking scheme exploits the high correlation among points in the same polygon in a map and achieves the reversibility of the whole scheme by an 8-point integer ...

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.

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.

A near reversible image watermarking algorithm
2010 International Conference on Machine Learning and Cybernetics, 2010Being a novel category of watermarking schemes, reversible watermarking algorithms were developed in recent years. As it can recover the watermarked data back to the original host signal, reversible watermarking algorithms are suitable for medical, military and other special fields. However, these algorithms have their defects, such as weak robustness,

Adaptive reversible image watermarking scheme
Journal of Systems and Software, 2011This paper presents an adaptive block sized reversible image watermarking scheme. A reversible watermarking approach recovers the original image from a watermarked image after extracting the embedded watermarks. Without loss of generality, the proposed scheme segments an image of size 2^Nx2^N adaptively to blocks of size 2^Lx2^L, where L starts from a ...

This section introduces the reversible audio watermarking (RAW) techniques. RAW can be classified according to how the inherent redundancies in the audio signals are utilized. Three types of redundancies and the corresponding RAW algorithms are reviewed. The companding (compression and expansion) approach employs the redundancy in representing a single

Reversible Watermarking by Coefficient Adjustment Method
2010 Sixth International Conference on Intelligent Information Hiding and Multimedia Signal Processing, 2010In this paper, a novel reversible watermarking method based on the coefficient adjustment technique is proposed. A host image is first decomposed into the integer wavelet transform (IWT) domain. Subsequently, a secret message is embedded into the low-high (LH), high-low (HL), and high-high (HH) sub-bands of the IWT using the coefficient adjustment ...

Reversible Digital Watermarking with Block Linking
2009 Fifth International Joint Conference on INC, IMS and IDC, 2009This paper proposes a novel reversible digital watermarking algorithm by block linking. First the input image is decomposed by a reversible integer transform. The expandable values for data embedding is divided into blocks which are linked by index. The location map is avoided to increase the capacity for embedding.
