  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.
