Review and Test of Steganography Techniques

Abstract: Steganography is the art of concealing a secret message within an appropriate-multimedia carrier such as images, audio, video files, and even network packets. Steganographic techniques have been used since ancient times to hide the message from third-parties deemed to be enemies. On one hand, Steganography is a useful technique that has been applied in various useful applications. On the other hand, however, the same technique has been applied and used for the wrong purposes by people who have ill intentions. The increase in computational power and increase in security-awareness over the past few years have propelled the application of steganography in computational security-techniques. Being robust, undetectable, and having a good capacity of hidden-data, steganography has been preferred for hiding data than watermarking and cryptographic-techniques. This paper clarifies the application of steganography on different multimedia-carriers by using various potential tools, methods, and principles to either apply or detect steganography techniques.
