Methods for Controlling the Authenticity of Textual Information Transfer on the Basis of Statistical and Structural Redundancy

In this paper, the problem of increasing information transfer authenticity is formulated. And to reach a decision, the control methods and algorithms based on the use of statistical and structural information redundancy are presented. It is assumed that the controllable information is submitted as the text element images and it contains redundancy, caused by statistical relations and non-uniformity probability distribution of the transmitted data. The use of statistical redundancy allows to develop the adaptive rules of the authenticity control which take into account non-stationarity properties of image data while transferring the information. The structural redundancy peculiar to the container of image in a data transfer package is used for developing new rules to control the information authenticity on the basis of pattern recognition mechanisms. The techniques offered in this work are used to estimate the authenticity in structure of data transfer packages. The results of comparative analysis for developed methods and algorithms show that their parameters of efficiency are increased by criterion of probability of undetected mistakes, labour input and cost of realization.
