Abstract | ||
|---|---|---|
•Security analysis of a recently proposed reversible data hiding scheme is given.•A novel scheme is proposed in encrypted domain based on sparse matrix compression.•The encryption parameter is generated by chaotic map and the image entropy.•The proposed scheme outperforms the former in both security and embedding capacity. |
