Cryptography is the science and art of encrypting and decrypting text data where Steganography is the science and art of hiding information. Steganography deals with composing hidden message so that only the sender and receiver know that the message even exists. A novel approach i. e. CryptSteg is introduced where sender embedding text message in the picture and send it to the receiver. In this...

A brief survey of some representative techniques of steganography and steganalysis is presented. Various methods developed in the authors’ laboratory are introduced, including symmetric LSB embedding, secure steganography in JPEG, palette, and uncompressed color images, histogram-based analysis and least histogram abnormality steganography, multiple-base notational system based embedding, stego...

Abstract Steganography is the art and science of writing hidden messages in such a way that no one apart from the intended recipient knows of the existence of the message. In today’s world, it is widely used in order to secure the information. Since digital forensics aims to detect, recover and examine the digital evidence and steganography is a method for hiding digital evidence, detecting the...

Today’s large demand of internet applications requires data to be transmitted in a secure manner. Data transmission in public communication system is not secure because of interception and improper manipulation by eavesdropper. So the attractive solution for this problem is Steganography, which is the art and science of writing hidden messages in such a way that no one, apart from the sender an...

Steganography is the powerful tool for hiding information inside useful cover medium in ways such that the hidden message is undetectable. In Greek language, stego means covered or secret and graphy means to write. Hence, steganography means covered writing. Transform domain steganography is one of the techniques used for hidden exchange of information in frequency domain and it can be defined ...

Steganography is the art of invisible communication. It is derived from the ancient Greece thousands of years ago (Johnson & Jajodia, 1998; Kahn, 1996), and grow rapidly in the past few years along with the development of digital technology and the internet. Modern steganography has been widely used in various scenarios such as secret communication, digital rights management, data temper detect...

The overwhelming growth in communication technology and usage of public domain channels (i.e. Internet) has greatly facilitated transfer of data. However, such open communication channels have greater vulnerability to security threats causing unauthorized information access. Steganography is the art of hiding and transmitting data through apparently innocuous carriers such as text, image, audio...

The paper presents a new approach in Image steganography. Information security is the important research field. Steganography process hides message into cover file and forms a stego file. In image steganography there is a need of method which will increase the security, reduce the distortion in the stego file and recovers the data without any loss. In the era of multimedia and internet there is...

Steganography is the art and science where writing messages are hidden in such a way that no user at end side knows exactly what message delivered. Data hiding characteristic related to object-oriented programming objects associated with data having predefined template. Thus, all not required by an object can be said "hidden". The word "Steganography" of Greek origin means "covered, or writing"...
