Abstract

Data hiding (DH) is an active research area in the information security field. DH technology hides the secret information within digital covers such as images and videos by causing unnoticeable degradation to their quality. It aims to distract the intruders' attention from the existence of secret data within the cover media which makes it preferred by many applications over some conventional security technologies like cryptography that encrypts the message as a sign of the existence of secret data. Copyright protection, media-content authentication and sending patient diagnosis are some emerging applications of DH. DH methods could be reversible or irreversible. Reversibility indicates the possibility of reshaping the exact carrier object once the secret message is retrieved while irreversibility does not guarantee so. Many of the existing DH methods in the literature tried to make a compromise between reducing the distortion of the cover object and increasing the embedding capacity. However, there is a need for more development in this compromise by presenting a more enhanced DH method.
