Every common person uses internet directly or indirectly in some spheres of his life. They mainly use the internet for information sharing. Also, information sharing has the primary importance in the field of Military Services, Medical Services, Mobile Services, and Investigation Agencies etc. The main hurdle in the path of information sharing is the security of information. The information sec...

Linguistic steganography is a branch of Information Hiding (IH) using written natural language to conceal secret messages. It plays an important role in Information Security (IS) area. Previous work on linguistic steganography was mainly focused on steganography and there were few researches on attacks against it. In this paper, a novel statistical algorithm for linguistic steganography detecti...

Today image steganography plays a key role for exchanging a secret data through the internet. However, the optimal choice of images formats for processing steganography is still an open issue; therefore, this research comes into a table. This research conducts a comparative study between Scalable Vector Graphics (SVG) image format and Portable Network Graphics (PNG) image format. As results sho...

Steganography is derived from the Greek word steganos which literally means “Covered” and graphy means “Writing”, i.e. covered writing. Steganography is the art and science of hiding messages in such a way that no one apart from sender and receiver identify the message. The paper describes the steganalysis technique for the detection of secret message in the image. The strong and weak point of ...

Steganography is a form of information hiding. Today there is a very large demand of applications which require data to be transmitted in a safe and secure manner. Steganography is one of the methods used for the hidden exchange of information and it can be defined as the study of invisible communication that does not attract attention from eavesdroppers and attackers. The main requirements of ...

This paper presents a review of multifarious methods available for image steganography. The steganography is an art and science of invisible communication. The image steganography is divided into four basic terminologies viz. cover image, message, stego image, embedding and extracting algorithm. In this paper comparison of steganography with other security techniques is done. Image steganograph...

This study combines the notion of both steganography [1] and visual cryptography [2]. Recently, a number of innovative algorithms have been proposed in the fields of steganography and visual cryptography with the goals of improving security, reliability, and efficiency; because there will be always new kinds of threats in the field of information hiding. Actually Steganography and visual crypto...

Steganography has received considerable press in the last three years, mostly due to the war on terror. This paper discusses the state of steganography by examining its current uses, limitations, and implications. In addition, this paper addresses the relationship between steganography, steganalysis and terrorism.

Steganography is the science that involves communicating secret data in an appropriate multimedia carrier, e.g., image, audio, and video files. The main goal of steganography is to ensure that the transmitted message is completely masked, thereby ensuring that the message is accessible only to the intended receiver and not to any intruders or unauthorized parties. In steganography, rather than ...

Steganography is the art of covered, or hidden, writing. The purpose of steganography is covert communication -to hide the existence of a message from a third party. This paper is intended as a high-level technical introduction to steganography for those unfamiliar with the field. It is directed at computer forensics examiners who need a practical understanding of steganography without delving ...
