AI Technical Summary
Existing reversible data hiding technologies for encrypted images are susceptible to single-point failures, meaning the data hider may be attacked or malfunction. The main technical problems with existing encrypted image technologies are that they mostly employ a single-hide model, which carries the risk of single-point failure. Furthermore, their low embedding rate fails to meet the high-capacity information transmission and storage demands of the big data era. Additionally, their high computational complexity means that image restoration accuracy is significantly affected by the embedding capacity.
By working collaboratively with the data owner, multiple data hiders, and the data receiver, and combining block scrambling, secret sharing, and Hamming encoding, reversible data hiding of encrypted images is achieved, ensuring data security and image integrity. Furthermore, the embedding rate is improved and computational complexity is reduced by embedding secret data three times.
In the event of an attack or malfunction of a single data hider, the security of the data and the integrity of the image are ensured. By increasing the embedding rate, it can meet the needs of high-capacity information transmission and storage, reduce computational complexity, and improve image restoration accuracy.
