Steganography and steganalysis are the prominent research fields in information hiding
paradigm. Steganography is the science of invisible communication while steganalysis is …

Transmitting confidential images between two channels suffer from hacking. Therefore,
protecting confidentiality has become a very essential issue. Recently, several methods are …

In recent years, reversible data hiding (RDH) has attracted extensive attention from the
academia. Besides RDH for uncompressed images, RDH for compressed images with …

This research article provides an up-to-date review of spatial-domain steganography.
Maintaining the communication as secure as possible when transmitting secret data through …

In the field of digital multimedia, numerous researchers have exploited data hiding for
providing secure communications. Because most multimedia is compressed in advance to …

A new steganography algorithm based on five protection layers has been suggested in this
paper for embedding a large amount of secret messaging in a color image, as represented …

A three-phase intelligent technique has been constructed to improve the data-hiding
algorithm in colour images with imperceptibility. The first phase of the learning system (LS) …

In this paper, we propose an effective image retrieval approach using block truncation
