Abstract :

Image processing is used to improve the quality of image. Now days, more focus is on reversible data hiding (RDH) in encrypted images, so it maintains the excellent property that the original cover image can be easily recovered without any loss after embedded data. All previous techniques embed data by reversibly vacating room from the encrypted images, which may be leads to some errors on data extraction and image restoration. In this paper, we propose a method by reserving room before encryption with a RDH algorithm and LSB algorithm, and thus it is easy for the user to reversibly embed data in the encrypted image. The proposed system is reversible, that is, data extraction and image recovery is without any loss. A reversible data hiding algorithm and LSB algorithm, which can recover the original image without any loss from marked image after the hidden data have been extracted. Experiments show that this RDH method can embed more than 10times as large payloads for the same image quality as the previous methods, such as for PSNR dB.
