Compared to conventional reversible data hiding (RDH) methods, the dual-image RDH
technique is an effective way to achieve greater embedding rate and better quality of the …

Dual-image reversible data hiding (RDH) technology has been an active research area and
became an essential part of information security because of its unique advantages in …

Security systems become the first consideration to prevent illegal access as interest of
information security has increased recently. Information hiding is one of the methods for …

Reversible data hiding (RDH) subtly alter the cover image for embedding the secret data,
