Development of Parameter Measurement Method of Information Systems

Abstract

Measurement and analysis of information systems parameters is a necessary element of their research. Unlike technical systems, in information systems parameters need to be selected basing on the analysis of their functional characteristics. In this work are reviewed peculiarities of information systems parameters selection. For such systems it is important is not only to measure some values, but also setting boundaries, scale etc. In this work is researched the concealment parameter. This parameter describes the level of ability to detect the hidden message in digital environment, providing that according to the concealment parameter it is invisible. To solve the task are used statistical methods of digital environment analysis. In the work, the scale of the concealment parameter is determined and method of measurement of its value is reviewed. The research provides tools to use this parameter and illustrate an example of conduction of measurements in information systems.
