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 new method or 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. But it is not enough to keep the contents of a message secret, it is also important to keep the existence of the information secret. The technique which provides this features, is called steganography. Steganography is the art and science of invisible communication. This accomplished through hiding information in other medium, thus hiding the existence of the information which is communicated. The word steganography is comes from the Greek words “stegos” meaning “cover” and “grafia” meaning “writing” defining it as “covered writing”[6]. In image hiding using steganography the information is hidden exclusively in images.
