Abstract: The system focus on Separable Reversible Data Hiding forEncrypted Palette Images with Color Partitioning and Flipping Verification.Reversible data hiding (RDH) into encrypted images is of increasing attentionto researchers as the original content can be perfectly reconstructed after theembedded data are extracted while the content owner’s privacy remainsprotected. The proposed method adopts a color partitioning method to use thepalette colors to construct a certain number of embeddable color-triples, whoseindexes are self-embedded into the encrypted image so that a data hider cancollect the usable color-triples to embed the secret data. By using theencryption key, the receiver can roughly reconstruct the image content.Experiments have shown that, our proposed method has the property that thepresented data extraction and image recovery are separable and reversible. Ourproposed method can provide a relatively high data-embedding payload, maintainhigh PSNR values of the decrypted and marked images, and have a lowcomputational complexity.
