We propose a natural scene statistic-based distortion-generic blind/no-reference (NR)
image quality assessment (IQA) model that operates in the spatial domain. The new model …

Reversible data hiding (RDH) algorithms are concerned with the recovery of the original
cover image upon the extraction of the secret data. In some RDH algorithms, embedding …

A novel image authentication scheme which can protect the image integrity of the
compressed images for block truncation coding (BTC) is proposed in this paper. In the …

This paper presents a novel watermarking method, applied to the medical imaging domain,
used to embed the patient's data into the corresponding image or set of images used for the …

Steganography (literally meaning covered writing) is the art and science of embedding
secret message into seemingly harmless message. Stenography is practice from olden days …

In this paper we present a comparative study of four different image steganography
algorithms based on orthogonal Haar Wavelet Transform and biorthogonal CDF9/7 …

Reversible data hiding (RDH) algorithms allow data protection and exact recovery of the
original cover image upon data extraction. Most of RDH algorithms attempt to embed data …

Information hiding can be seen everywhere in our daily life, and this technology improves
the security of information. The requirements for information security are becoming higher …

Steganography is an ability of concealing information inside the cover in such a way it looks
like simple cover though it has concealed information. There are many techniques to carry …

To provide an added security level most of the existing reversible as well as irreversible
image steganography schemes emphasize on encrypting the secret image (payload) before …
