Secure Reversible Image Data Hiding Over Encrypted Domain via Key Modulation

Abstract 

This Secure Reversible Image Data Hiding Over Encrypted Domain via Key Modulation paper proposes a novel reversible image data hiding scheme over encrypted domain. Compared with the state-of-the-art methods, the proposed approach provides higher embedding capacity 

and is able to perfectly reconstruct the original image as well as the embedded message. 

REVERSIBLE image data hiding (RIDH) is a special category of data hiding technique, which ensures perfect reconstruction of the cover image upon the extraction of the embedded message.The early works mainly utilized the lossless compression algorithm to compress certain image features, to vacate room for message embedding

However, the embedding capacity of this type of method is rather limited

and the incurred distortion on the watermarked image is severe.

Recently, the research on signal processing over encrypted domain has gained increasing attention, primarily driven by the needs from cloud computing platforms and various privacy-preserving applications.This has triggered the investigationof embeddingadditionaldata in the encrypted images in a reversible fashion.
