Advanced reversible Data Hiding With Encrypted Data
This addresses security and reliability issues in data hiding for applications like multimedia communication, though it appears incremental as it builds on existing RDH methods.
The paper tackles the problem of data security and error-free extraction in reversible data hiding by proposing a scheme that encrypts both the embedded data and the host image, achieving significantly improved PSNR and extending the method to videos.
The advanced RDH work focuses on both data encryption and image encryption which makes it more secure and free of errors. All previous methods embed data without encrypting the data which may subject to errors on the data extraction or image recovery. The proposed work provides a novel RDH scheme in which both data and image can be encrypted and extracted reversibly without any errors. In the proposed work, data extraction and image recovery are free of any errors. The PSNR is significantly improved in the proposed work. This advanced work also performs data hiding in videos.
