Image steganography is a technology that hides sensitive information into an image. The
traditional image steganography method tends to securely embed secret information in the …

Owing to the inefficiency to hide large volume of secret data for the reversible data hiding
(RDH) image steganography approaches, we propose two improved RDH based …

Pixel value differencing (PVD) and least significant bit substitution (LSB) are two widely used
schemes in image steganography. These two methods do not consider different content in a …

Recently, reversible information hiding (RIH) methods have drawn substantial attention in
many privacy-sensitive real-time applications, such as the Internet of Things (IoT) enabled …

LSB matching revisited is an LSB‐based approach for image steganography. This method is
a type of coding to increase the capacity of steganography. In this method, two bits of the …

Since the inception of the reversible data hiding (RDH) concept, it has been a compelling
topic in the field of data hiding. Being reversible, it has the ability to restore the original …

Massive advances in internet infrastructure are impacting e-healthcare services compared to
conventional means. Therefore, extra care and protection is needed for extremely …

Image steganography has been widely adopted to protect confidential data. Researchers
have been seeking to improve the steganographic techniques in order to increase the …

Image steganography is a technique for hiding the secret data in a carrier image. This paper
proposes a novel n-right most bit replacement image steganography technique to hide the …

The need to protect confidential data stored on personal computers (PCs) or sent to other
parties has increased significantly. Therefore, a secure, high-capacity strategy is needed to …
