Watermarking Is Not Cryptography [chapter]

Ingemar J. Cox, Gwenaël Doërr, Teddy Furon
2006 Lecture Notes in Computer Science  
We note that the fields of communications and cryptography are quite distinct and while communications systems often combine technologies from the two fields, a layered architecture is applied that requires  ...  We believe that the fundamental role of watermarking is the reliable embedding and detection of information and should therefore be considered a form of communications.  ...  Since much of the motivation for watermarking is driven by security concerns, it is not surprising that analogies have been made between watermarking and cryptography.  ...

Halftone Image Watermarking based on Visual Cryptography

Jaishri Chourasia, M. B. Potdar, Abdul Jhummarwala, Keyur Parmar
2012 International Journal of Computer Applications  
At the time of watermark embedding verification share is generated and at the time of watermark extraction master share is generated using (2, 2) visual cryptography scheme.  ...  The scheme does not embed the watermark directly on the halftone image instead watermark will be divided into the parts called as shares.  ...  The scheme is based on visual cryptography and watermark is embedded as a share, which does not reveal complete information about the original watermark, hence it will reduce the chances of watermarking  ...

A Review on Secret Image Protection using Reversible Watermarking

Samrudhi S. Mamarde, Dr. Siddharth A. Ladhake
2017 IJARCCE  
A cryptography technique provides security to image and watermark provides authentication to images.  ...  In this paper we are going to proposed a technique in which first the secret image is encrypted using a key image, then encrypted image is watermarked using the watermark image, then it is passed through  ...  The order of the operations is important; if the order is not followed then the original image will not be obtained.  ...

Hiding Multiple Watermarks in Transparencies of Visual Cryptography

Hao Luo, Jeng-Shyang Pan
2007 Third International Conference on Intelligent Information Hiding and Multimedia Signal Processing (IIH-MSP 2007)  
This paper proposes a scheme to hide multiple watermarks in transparencies of visual cryptography. On one hand, the main properties of the traditional visual cryptography are still maintained.  ...  On the other hand, not only the encrypted image can be visible when stacking the transparencies, but also two extra watermarks can be extracted with simple computations.  ...  In visual cryptography, it is desirable to embed data in encrypted transparencies to protect them. In this paper, we focus on embedding two different watermarks transparencies in visual cryptography.  ...

Importance and Techniques of Information Hiding : A Review

Richa Gupta, Sunny Gupta, Anuradha Singhal
2014 International Journal of Computer Trends and Technology  
Information or data is very crucial resource to us. Thus securing the information becomes all the more necessary.  ...  The communication media through which we send data does not provide data security, so other methods of securing data are required. Information hiding plays a very crucial role today.  ...  Digital watermarking is a passive protection tool. It just marks the data, but does not degrade it nor controls access to data [5].One application of digital watermarking is source tracking.  ...
