Digital steganography has a long history, starting to be developed in the 90s until now. The
main aspects of early steganography are security, imperceptibility, and payload. Security is …

Steganography is the science and art of covert communication. Conversely, steganalysis is
the study of uncovering the steganographic process. The evolution of steganography has …

A novel local binary pattern‐based reversible data hiding (LBP‐RDH) technique has been
suggested to maintain a fair symmetry between the perceptual transparency and hiding …

In this paper, a novel steganography algorithm based on local reference edge detection
technique and exclusive disjunction (XOR) property is proposed. Human eyes are less …

Recent advancement in the digital technology and internet has facilitated usage of
multimedia objects for data communication. However, interchanging information through the …

Given the increased popularity of the internet, the exchange of sensitive information leads to
concerns about privacy and security. Techniques such as steganography and cryptography …

Data hiding called steganography is a security technique to protect secret data throughout
the transmission from malicious attackers. The purposes of steganography are to obtain …

The authenticity and integrity of healthcare is the primary objective. Numerous reversible
watermarking schemes have been developed to improve the primary objective but …

This paper proposes an improved image steganographic technique based on the principle
of modified least significant bit (LSB) substitution and LSB matching, to improve the capacity …

This paper proposes an improved data hiding technique using the principle of least
significant bit (LSB) substitution and pixel value differencing (PVD). It addresses two issues …
