Steganography is the art and science of covered or hidden writing. The purpose of steganography is covert communication to hide the existence of a message from an intermediary. Digital Steganography algorithms have been developed by using texts, images and audio etc as the cover media. In this approach, a security model is proposed which imposes the concept of secrecy over privacy for text mess...

ABSTRACT: Steganography hides the existence of the data inside any cover file. There are different file formats used in steganography like text, image, audio and video. Out of these file formats image steganography is followed in this paper .One of the major objective of hiding data using image steganography is to hide the data in an image, so that the changes in the intensity of the colors of ...

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, literally meaning “secret writing”, involves hiding a data file in another innocuous-looking file. From the time of Herodotus in Greece, to the defense mechanisms of today, steganography has been used to deny one’s adversaries the knowledge of message traffic. Steganography takes one piece of information and hides it within another. A “container file” holds the secret message in ...

Image steganography is used to embed covert messages in the form of files, text, or other images in digital images. The intent is to transmit hidden information. Steganalysis is the process used to detect hidden messages in images. Although steganography is not a new discipline, it has become increasingly important in today’s digital world where information is often and easily exchanged through...

Secure transmission of information is one of the big challenges of knowledge society. Steganography is the transmission of secret messages embedded within other covering messages which conceal the existence of underlying messages (steganosis). In cryptography however, the presence of secret messages is known. We develop a new Steganography method based on Chaos, for concealing texts or images e...

In today's digitised era almost all data is transferred digitally which is very easy and advantageous but it also has some shortcomings i. e. the security of this data is very important. So different techniques such as steganography and cryptography are used to ensure security of data being sent over a medium. In steganography, the secret data is concealed within an object known as cover m...

Computer technology and the Internet have made a breakthrough in the existence of data communication. This has opened a whole new way of implementing steganography to ensure secure data transfer. Steganography is the fine art of hiding the information. Hiding the message in the carrier file enables the deniability of the existence of any message at all. This paper designs a stego machine to dev...

Steganography is the science of hiding data by embedding it in cover files without altering it. The cover media may be text, image, voice or video streams in a digitized format. Steganography is used to prevent unauthorized users from becoming aware of the very existence of a message, let alone what it contains. These new techniques makes hidden message indistinguishable from the white noise. E...
