AN OVER VIEW OF STEGANOGRPHY

Abstract

Abstract: The paper explore about an overview of steganography, different methods of steganography, its applications and how it is different from cryptography Digital communication has become an essential part of infrastructure. Nowadays, a lot of applications are Internet-based and 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 different techniques like cryptography and steganography  are used to secure the communication. Steganography is the scheme of hiding the existence of secret information in the cover file.
