摘要: This work proposes a novel reversible visible watermarking scheme for encrypted images. In the scheme, original plaintext image is by bit-wise exclusive-or operation. Although data-hider does not know content, he may modify part of data corresponding to black pixels binary watermark insert watermark. Meanwhile, some additional used content recovery are also embedded using wet paper coding. After receiving marked image, user with encryption key perform direct decryption obtain visibly while and data-hiding keys can data-extraction, image-decryption, content-recovery retrieve image.
