A SURVEY ON SECRET MESSAGE HIDING TECHNIQUES USING SYMMETRIC CRYPTOGRAPHY

Abstract

Since the rise of the Internet one of the most important factors of information technology and communication has been the security of information. Cryptography was created as a technique for securing the secrecy of communication and many different methods have been developed to encrypt and decrypt data in order to keep the message secret. Unfortunately it is sometimes not enough to keep the contents of a message secret, it may also be necessary to keep the existence of the message secret. The technique used to implement this, is called Steganography. steganography is the art and science of invisible communication as we mentioned in abstract part. This is accomplished through hiding information in other information, thus hiding the existence of the communicated information..it is important phenomenon to secure the message data.
