Simulation of Typical Behavior User Using Markov Models

described the problem of modeling the behavior of a typical user of an electronic information system to detect the fact of use of his account by another person. Investigated method that allows presenting the typical behavior of a user in the form of Markov model and further assessing the target user's behavior compared with the pattern presented in the corresponding model. In the process of research an experimental system was developed that allows evaluating the possibility of using Markov models to solve this problem and the statistical properties of the created model. The results of the initial experiments show good suitability of this approach
