Abstract

Reversible data hiding (RDH) is a form of information hiding that allows both the host sequence and the embedded data to be recovered without losing the marked sequence. In addition to media annotation and integrity authentication, RDH has recently been innovatively used in various other fields. With the advancement of digital communication, computer technologies, and the Internet, ensuring information security is considered one of the most difficult challenges in communication to protect user data. Numerous reversible and steganographic techniques are available for hiding or securing data, such as text, images, and protocols, which can be secretly transmitted to a receiver. A powerful data security technique is reversible data hiding in encrypted images (RDHEI). As digital techniques for transmitting and storing images become more widespread, it is increasingly important to consider how to protect image confidentiality, integrity, and authenticity. Any text associated with the image, such as authentication or author information, could be used as data. The receiver must be able to recover both the hidden data and the original image. Reversible data hiding is a technique that meets this requirement by allowing the host image to be accurately recovered. This research paper extends the performance parameters used in encryption processes and analyses their security issues using the MATLAB tool. We compare our proposed technique to the existing RDHEI technique, not only in terms of embedding but also in other aspects.
