Abstract: A reversible data hiding scheme in encrypted image (RDHEI) based on dualdomain joint coding and secret sharing is proposed to improve the security and embedding capacity. First, the image is predicted by median-edge detector (MED) and the optimal threshold l is calculated. Pixels with different prediction errors are divided into predictable and unpredictable pixels according to the threshold. Second, to enhance the embedding capacity, the dual-domain joint coding is adopted to compress the auxiliary information on the pixel domain and bit domain, respectively. Then, the original image is encrypted to generate multiple encrypted images using the secret sharing technique based on cipher feedback, where the auxiliary information and secret data from multiple parties are embedded into the encrypted images. Finally, the embedded secret data as well as the original image are perfectly recovered based on the extracted auxiliary information. Experimental results show that the algorithm significantly improves the embedding capacity and security.

Key words: reversible data hiding in encrypted image (RDHEI), dual-domain joint coding, secret sharing, cipher feedback, high capacity, strong security
