Have vykorystovuyutsia modern methods methods of system analysis and theory of information security, mathematical apparatus of graph theory, Boolean algebra, linear algebra, combinatorics, control theory and decision-making, methods of statistical data processing and programming methods and symbolic computational mathematics. The procedure of fragmentation of data items, which allowed to increase the security of dependent attribute access context information and to assess the effectiveness of protection systems. Developed a set of criteria influencing the effectiveness of relevant systems of information protection, context-oriented model of forming of process of detection of violations of security of information resources is dependent on the attribute of the atomic-molecular model of informational resources for the development process multirunner access control, an improved method of scheduling transactions, which makes it impossible for a situation of simultaneous access to information resources and has the ability to maintain their integrity; the structure of information resources with the breakdown of the atoms and molecules of protection; an experimental study of software model of context-oriented protection of information resources. Implementation and practical use of these developments confirmed the validity of theoretical hypotheses and conclusions of scientific work. Product Description popup.authors Ivanchenko Yevgenia V.
