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.

Development of Requirements Specification for Steganographic Systems

“…A connected concept to the approach defined in Section III is the Universal Stegoconstructor, which is described in detail in [25] and [11]. It allows the customer to receive and the developer to select the most appropriate steganographic method based on the criteria defined.…”

“…The concept of the Universal Stegoconstructor[25] modified with the inputs from the approach introduced in the present research (A, B, C, D).…”

Universal Stegoconstructor in Context of Intellectual Property Protection

“…Authors of this paper developed the concept of universal stegoconstructor in their previous work [3], which allows receiving the most appropriate data hiding method for the chosen data carrier based on the given criteria [3]. As watermarking is special kind of data hiding, authors decided to adapt the stegoconstructor for finding/creating optimized watermarking technique.…”

“…On the 2 nd step the algorithm is applied, which transforms host signal (or data carrier), taking into account format features chosen by the customer, so that methods of theory of signal transmission (TST) could be used comfortably [3], [12]. In this step also limitation list is created, which influences the selection of digital watermarking method in next steps.…”

“…This paper focuses on digital watermarking techniques. The authors describe the basics of digital watermarking systems, its area of use, introduce the problem of selection of the most appropriate method of watermarking protection for concrete data carrier or host signal and present the adapted universal stegoconstructor concept [3] to resolve the problem mentioned.…”
