MATHEMATICAL SOFTWARE FOR DETECTING CONFIDENTIAL DATA IN ELECTRONIC DOCUMENTS

abstract 1181604081 issue 118 pp. 1267 – 1281 29.04.2016 ru 532
In the article, we develop the software for process of confidential data detection based on the knowledge bases technology. The algorithm of detection of confidential data in the electronic documents transferred outbound of protected information system, due to application of linguistic technologies of the thorough text analysis is presented. The estimation of computing complexity of the developed algorithm is made up. The developed data structures and algorithm are realized in the programming language C++. Results of the experiments, confirmed workability of the developed algorithm are presented. The performed experimental researches of the developed algorithm have shown its practical applicability. The estimation of quality of confidential data detection is made up. The obtained estimations of detection quality have shown, that the developed structures of data and algorithm provide more effective and qualitative solution of problems of the confidential information detection in electronic documents, at due to application of knowledge bases technology where the subject domain of the analyzed information is considered. Distinctive feature of the developed algorithm of confidential data detection is the use of rapid access to hashed concept ontographs simultaneous implementation of knowledge base rules, which allows raising indicators of completeness and accuracy of detection. A scope of application of the developed software is the protection frames of the information intended for revealing of an information transfer containing data of confidential character in electronic documents outbound of protected information system with violation of security policy

MATHEMATICAL THEORY OF RATINGS

abstract 1141510001 issue 114 pp. 1 – 26 30.12.2015 ru 1351
When developing management solutions with the aim of joint consideration and comparison of various factors, partial removal of uncertainty is widely used ratings. In the theory of decisionmaking in almost the same sense, we use the terms "composite index" or "integrated indicator". The article is devoted to the mathematical theory of ratings as tools for studying socio-economic systems. We considered, primarily, linear ratings which is a linear function from a single (private) indicators (factors, criteria), constructed using the coefficients of importance (weightiness, importance). The study discusses the factors affecting the magnitude of the ratings. Three groups of causes affect the value of a line ranking: the ways of measurement of individual indicators, the choice of the set of indicators; the values of the coefficients of importance. We considered binary ratings when the rating takes two values. To compare the proposed rankings we use a new indicator of the quality of diagnostics and prognostic power. Significantly, in many managerial situations, significant differences between objects are identified using any rating. According to the fundamental results of stability theory, the same source data should be processed in several ways. Matching findings, obtained using multiple methods, likely reflect the properties of reality. The difference is the result of a subjective selection method. When using the results of the comparison of objects according to several indicators (criteria ratings), including in dynamics, very useful is the selection of the Pareto set. We discuss the examples of the application of the decision theory, expert evaluations and rankings when developing complex technical systems
