High-capacity separable reversible data-Hiding method in encrypted images based on block-level encryption and Huffman compression coding
Reversible data hiding in encrypted images (RDHEI) is a technology that embeds data directly in the encrypted images without decryption or knowledge of the content of the images. However, it is difficult to vacate room from the encrypted image. This problem limits the embedding capacity of the exist...
