Lossless Image Recovery Using Reversible Data Hiding
Recently, more and more importance is given to reversible data hiding (RDH) technique in images, since it has the capability of recovering the original image which is used for embedding data, without loss protecting the image content’s confidentiality. All previous methods embed data by reversibly vacating room from the images, which may be subject to some errors on data extraction and/or image...
متن کاملReversible Data Hiding Scheme Using Toffoli Gate
In this paper, we propose a new reversible data hiding scheme without distortion of stego image. In the proposed scheme, Toffoli gate is used in embedding and extraction procedures. This gate provides a distortionless of stego image because it has a characteristic of self-inverse. In the experimental results, the embedding capacity and PSNR of the proposed technique are greater than the previou...
متن کاملLossless Data Hiding Technique using Reversible Function
The most of the previous lossless data hiding techniques are that secret data are embedded into cover image. So, the relationship between the embedding capacity and PSNR of these techniques is always an inverse proportion. In contrast, the embedded position information of secret data are embedded into a location map in the proposed technique in order to achieve thedirectly proportional relation...
متن کاملReversible Data Hiding Using Improved Interpolation Technique
Reversible Data hiding is a process of hiding information into a cover image. There are various techniques used for hiding secret data. Audio, video, image, text, and picture can be used as a cover medium in data hiding. In images, Reversible Data Hiding (RDH) is a method which is very helpful in the recovery of original cover after the inserted message is extracted. This vital method is broadl...
متن کاملReversible Data Hiding Using Contrast Enhancement Approach
Reverse Data Hiding is a technique used to hide the object's data details. This technique is used to ensure the security and to protect the integrity of the object from any modification by preventing intended and unintended changes. Digital watermarking is a key ingredient to multimedia protection. However, most existing techniques distort the original content as a side effect of image protecti...
