Paper Details

This technology proposes a lossless, reversible, and the combined information activity schemes for thecipher text pictures encrypted by the public key cryptosystems with probabilistic and the polymorphic properties withinthe lossless theme, the cipher text pixels square measure replaced with the new values to implant the extra informationinto many LSB-planes of the cipher text pixels by the multiple layer wet paper committal to writing. Then, the embeddedinformation may be directly extracted from the encrypted domain and also the information embedding operation doesn'thave an effect on secret writing of original plaintext image within the reversible theme, preprocessing is utilized to shrinkthe image bar graph before the image coding, in order that the modification on encrypted pictures for the informationembedding won't cause any constituent oversaturation in plaintext domain. Though a small distortion is introduced, theembedded information may be extracted and also a original image may be recovered from the directly decrypted image.As a result of the compatibility between a lossless and reversible scheme, the info embedding operations within 2manners may be at the same time performed in the associate degree encrypted image. With the combined technique, areceiver could extract the region of embedded information before secret writing, and extract another part of embeddedinformation and recover initial plaintext image when secret writing.
