Executive Summary

The mass diffusion of digital communication needs the special means of security. Cryptography concentrates on rendering the message unreadable to any unauthorized persons who might intercept them. In contrast, steganography is a method of concealing the existence of message to allow a secure communication in a complete undetectable manner. Digital image is the most common type of carrier used for steganography. This paper, has proposed a steganography mechanism, that reads the message and converts it to a colored image, that is transmitted to the authorized destination, and from which is extracted the information needed to reconstruct the original message.
