A prevalent study on secure medical image digitization through RDH

Reversible data hiding has its own significance in medical image systems. Medical imaging has key applications in healthcare systems, where the private information about a person needs to be shared among the authenticated persons only without any distortion during data hiding and transmission. RDH is one of most practicable techniques of privacy preservation with lossless recovery at receiver's end. Numerous RDH techniques are proposed on different image domains like, compressed and uncompressed. This paper summarizes the existing RDH algorithms for medical images.
