Use of formal facilities of description of processes of grant of rights access

Abstract

This work covers the rights accesssystems that can have a variety of interpretations, from representing them as an ac-cess rights matrix to their representation in the form of attribution of certain roles to users who request access rights. Namely, we performed the analysis of parameters that characterise the DIS-type information systems in order to choose the most appropriate means of their formal description. We have formulated a number of state-ments and definitions that simplify such analysis in future and determined a number of mandatory requirements to conduct this analysis.And namely importance of data is de-fined as a parameter that characterizes the frequency of use of the data for a predetermined period during which the corresponding data is used. Also picked measure data pri-vacy through the degree of danger , which can lead to not authorized use of data in solving the problem . We consider the concept of anomalies and proved the relationship do-main interpretation of the information system at the struc-tural level.
