Intelligent Modified Difference Expansion for Reversible Watermarking
A Reversible Watermarking (RW) using Difference Expansion (DE) algorithm plays an important role on content authentication for highly secured medical and military images. According to this algorithm, the least significant bit (LSB) of inter-pixel differences (between a pair of neighboring pixel) is used to embed secret data. It is seen that none of the DE works focuses on structural information...
متن کاملReversible Watermarking by Difference Expansion
Reversible watermark has drawn lots of interest recently. Different from other types of digital watermarks, a reversible watermark has a special feature that the original digital content can be completely restored. In this paper we describe a high capacity and high quality reversible watermarking method based on difference expansion. A noticeable difference between our method and others is that...
متن کاملRecursive Reversible Image Watermarking Using Enhancement of Difference Expansion Techniques
This paper proposes a high capacity reversible image watermarking scheme based on enhancement of difference expansion method. Reversible watermarking enables the embedding of useful information in a host signal without any loss of host information. We propose an enhancement of Difference Expansion technique whereby we can embed recursively into multiple layer of payload for grey scale and also ...
متن کاملA Reversible Watermarking Scheme Based on Difference Expansion for Wireless Sensor Networks
Wireless sensor networks are self-organized and data-centric. Sensors are typically operated in uncontrolled and possibly hostile environment. Watermark technology has been used for integrity and copyright protection. Some specific application scenarios, such as military, telemedicine and satellite remote sensing, are strict with data integrity and accuracy. They do not allow any change and mus...
