The growth of technology in computer science and popularity of information technology among the common people changed the means of information exchange using mail services of paper messages to Email services of electronic messages. From the very beginning of the use of these types of technologies, the security offered by these techniques is a big question. Popular solutions for ensuring the security of electronic messages are cryptography and steganography. Steganography is the art of hiding the existence of the communication message before sending it to the receiver. The common techniques used are – Symmetric cryptographic algorithms and substitution steganography methods. Since these techniques are popular and common, now everybody knows how these techniques ensure the security of messages. Message hackers can now easily break these techniques because of the intense experience they might have earned by handling these types of techniques. So, there exists need for new techniques and methods to ensure the security of message. To overcome the problems associated with using the existing common and popular methods, the proposed methods use the concepts of RGB color model to hide the encrypted contents. In this method the encrypted contents are converted to a bitmap image. It has many advantages over the simple symmetric key encryption and popular LSB steganography method. The first proposed technique uses concept of color only, whereas the second method combines geometric figures with color codes to hide the message. These two methods can be considered as new techniques of generation steganography.
