Kutter Steganographical Method's Improvement and Concept of Universal Stegoconstructor

Abstract

Kutter Steganographical Method's Improvement and Concept of Universal Stegoconstructor Information interchange is one of the main processes in human everyday life. This process was simplified due to development of modern technologies, especially computer technologies. But the drawback of such transmission is data exposure. Steganography tries to find possible decisions of this problem. The main difference between steganography and cryptography: malicious person has no any data about information hiding in first case. That's mean he doesn't think about possible valuable information in message. This paper contains information about the conception of digital steganography's development as protection method of the confidential information. Classification of the basic scopes is given, and the problems facing to the given science are explained. Some aspects of steganography were examined in the context of the theory of signal transmission. The properties of possible universal stegomethod's constructor are determined on the basis of required transmission's reliability. The way, which increases the probability of a bit correct detecting in Kutter method till 70%, is offered as improvement of data embedding procedure. Disadvantages of the original steganographical Kutter method's were commented at the same time. Results of experiments are presented as numerous histograms.
