Reversible Data Hiding in Encrypted Images by Reserving Room Before Encryption
Keywords:
Image Encryption, Image Recovery, Reversible Data Hiding.Abstract
(RDH) in encrypted images, since it maintains the excellent property that the original cover can be loss less recovered after embedded data is extracted while protecting the image content’s confidentiality. All previous methods embed data by reversibly vacating room. Recently, more and more attention is paid to reversible data hiding from the encrypted images, which may be subject to some errors on data extraction and/or image restoration. In this report, we propose a novel method by reserving room before encryption with a traditional RDH algorithm, and thus it is easy for the data hider to reversibly embed data in the encrypted image. The proposed method can achieve real reversibility, that is, data extraction and image recovery are free of any error. Experiments show that this novel method can embed more than 10 times as large payloads for the same image quality as the previous methods, such as for PSNR dB.
