WebApr 9, 2024 · RDH in encrypted images (RDHEI) are categorized in two classes: Reserving Room before Encryption (RRBE) and Vacating Room after Encryption (VRAE) . These two classes belong to Embedding stage of RDH. VRAE provides encryption of original media followed by secret information embedding. WebFeb 1, 2024 · From the process of reserving room, most RDHEI methods can be divided into two frameworks: vacating room after encryption (VRAE) and reserving room before encryption (RRBE).
