Reversible image watermarking using modified difference expansion

2012 Third International Conference on Emerging Applications of Information Technology, 2012
Reversible watermarking (RW) using difference expansion (DE) is quite popular to embed data followed by recovery of the original image. According to this algorithm, the least significant bit (LSB) of inter-pixel differences (between a pair of neighboring pixel) is used to embed watermark data.

Database Watermarking Algorithm Based on Difference Expansion

2019
Database watermarking technology is an important means to protect database information security. Firstly, the key components of the database are divided into several sub-groups by using the key hash function. Then, the size of the Pearson correlation coefficient is used in the sub-group to be selected the attribute column to be embedded in the ...

Reversible data embedding using a difference expansion

IEEE Transactions on Circuits and Systems for Video Technology, 2003
Reversible data embedding has drawn lots of interest recently. Being reversible, the original digital content can be completely restored. We present a novel reversible data-embedding method for digital images. We explore the redundancy in digital images to achieve very high embedding capacity, and keep the distortion low.
