Abnormal Action Detection based on Markov Models
Automatic Control and Computer Sciences
The task of using Markov chains to develop a statistical behavioral model of a DS user to
detect abnormal activity is described. In order to verify the assumption about the possibility of using
this method in electronic health records, a program system was developed. The experiments with the
system showed that the approach in question could be efficiently applied in abnormal action detection, for example, in data systems handling sensitive information.
