A Novel Reversible Data Hiding Algorithm Based on Enhanced Reduced Difference Expansion
Symmetry, 2022 Reversible data hiding is a data-hiding technique which has the ability to recover the original version from stego-images after the secret information is extracted. In this paper, we propose a novel reversible data-hiding scheme based on an enhanced reduced difference-expansion technique.

Proceedings of The 6th IIAE International Conference on Intelligent Systems and Image Processing 2018, 2018 This paper proposed a reversible multiple layer data hiding to improve the method proposed by Arham et al. using the relevance of pixels to modify the block size and change the scan mode to enhance image embedded capacity. The experimental results shows that the smaller the block, the lower the amount of hidden information, the larger the block, and ...
