Randomized trial demonstrates improved data embedding in encrypted images, suggesting enhanced privacy control.

The research aims to improve reversible data hiding in encrypted images while allowing fine-grained recovery authorization.
Developed a high-capacity reversible data hiding scheme incorporating dual-stage bit-plane compression and block rearrangement.
Employed pixel predictors to generate prediction errors and applied adaptive hierarchical block variable-length coding for compression.
Introduced a ciphertext-policy attribute-based encryption mechanism for flexible, policy-driven recovery.
Achieved competitive embedding performance with exact recovery of the original images.
Supported flexible multi-user scenarios for policy-driven image recovery.
Experiments on datasets like BOSSBase and BOWS-2 confirmed the efficacy of the proposed method.

Peng et al. (2026) studied this question.
