Reserving Room Approach on Reversible Data Hiding before Encryption
Now-a-days peoples give more attention while transmitting secure data. For that Reversible Data Hiding algorithm is mostly preferred since it maintains the property that the original image is recovered from encrypted image and embedded data without analysis into it. But the existing method embeds data by reversibly vacating room from encrypted images, which will further leads to the loss of dat...
متن کاملReversible Data Hiding For Embedding Data Securely in Encrypted Image by Reserving Room Before Encryption
Reversible data hiding with image encryption (RDH), since it maintains the excellent property that the original cover can be losslessly recovered after embedded data is extracted while protecting the image content’s confidentiality. In previous work vacating room after encrypted image, which subject to some errors on data extraction and/or image restoration. In this paper, a novel method by res...
متن کاملReserving Room Before Encryption
Recently, more and more attention is paid to reversible data hiding (RDH) in encrypted images, since it maintains the excellent property that the original cover can be losslessly recovered after embedded data is extracted while protecting the image content’s confidentiality. All previous methods embed data by reversibly vacating room from the encrypted images, which may be subject to some error...
متن کاملWatermarked and Encrypted Image for Reversible Data Hiding by Reserving Room Algorithm with Random Pixel Data Hiding
Reversible Data Hiding (RDH) gaining the attraction in the world of secured message passing through encrypted images. It is due to the excellent property of recovering the original cover or image after embedded data is extracted while protecting the encrypted image content’s confidentiality. The related works may embed data by reversibly vacating room from the encrypted images, which may be sub...
متن کاملCommutative reversible data hiding and encryption
This work proposes a novel scheme of commutative reversible data hiding and encryption. In encryption part, the gray values of two neighboring pixels are masked by same pseudo-random bits. In data-hiding part, the additional data are embedded into various bit planes with a reversible manner, and a parameter optimization method based on a capacity–distortion criterion is used to ensure a good pe...
