An improved robust reversible database watermarking scheme

Discover Computing
Most existing database watermarking algorithms cause permanent distortion to original carrier data, and it is difficult to achieve a balance between watermark embedding capacity and data distortion.

Novel Scheme of Reversible Watermarking With a Complementary Embedding Strategy

IEEE Access, 2019
In this paper, a new scheme of reversible watermarking is proposed using a complementary embedding strategy in the spatial domain. The proposed scheme consists of two stages: horizontal direction embedding and vertical direction embedding.

Reversible and semi-blind relational database watermarking

, 2007
Database watermarking has received significant research attention in the current decade. Although, almost all watermarking models have been either irreversible (the original relation cannot be restored from the watermarked relation) and/or non-blind ...

Survey on Reversible Watermarking

IOSR Journal of Computer Engineering, 2013
A number of research papers has been produced about reversible watermarking. Reversible watermarking is one of the important scheme of the watermarking schemes. Some security measures must be there to protect the records from unauthorized user and destruction of information.

VLSI Implementation of Reversible Watermarking using RCM

, 2015
In this paper the design and implementation of image watermarking algorithm called reversible contrast mapping (RCM) is given. Watermarking is to embed the one important information into the cover media to provide the security to data.

Pyramid Difference Reversible Image Watermarking Scheme

, 2012
A reversible watermarking scheme extracts the embedded watermarks and then recovers the original image from the watermarked image. This study presents a reversible image watermarking scheme based on the proposed block centering difference method and the ...
