Reserving room before encryption

Webencryption and vacating room, i.e., reserving room prior to image encryption at content owner side, the RDH tasks in encrypted images would be more natural and much easier which leads us to the novel Fig. 3: RRBE framework framework fig3.shows, “reserving room before encryption (RRBE)”. The content owner first reserves enough space on WebIn encryption phase, a stream cipher is used to mask the original content. Then, a data hider compresses a part of encrypted data in the cipher-text image using LDPC code, and inserts the compressed data as well as the additional data into the part of encrypted data itself using efficient embedding method.
