Steganography is the science that involves communicating secret data in an appropriate
multimedia carrier, eg, image, audio, and video files. It comes under the assumption that if …

This paper presents a lossless and reversible steganography scheme for hiding secret data
in each block of quantized discrete cosine transformation (DCT) coefficients in JPEG …

Capacity and invisibility are two targets of the methods for information hiding. Because these
two targets contradict each other, to hide large messages into the cover image and remain …

Steganography's role in secret communication extends from concealing information to
communication. As one of several possible approaches to embed confidential information in …

The paper describes a short survey on different types of steganography techniques for
image in spatial and transform domains and steganalysis techniques for the detection of …

Data hiding is an important technique for covert communication that embeds secret data into
a cover image with minimal perceptible degradation. Lossless data hiding is a special type …

Reversible data embedding is a very important issue, especially in dealing with sensitive
images such as military data and medical data. Based on the edge-directed prediction …

In recent years, chaotic systems have surfaced to become an important field in
steganographic matters. In this paper, we present a simple cryptic-free least significant bits …

In our modern life, persons and institutions alike are rapidly embracing the shift toward
communication via the Internet. As these entities adopt a faster and efficient communication …

The process of content confidentiality of the medical diagnostic reports and the scanned
image of patients among doctors with balancing proficiency for mutual dealing will provide …
