The Motif-Based Approach to the Analysis of the Employee Trajectories within Organization

Abstract EN

The analysis of the employees’ movement within organization building is an important task of the investigation of the business processes existing in the organization, including provision its cyberphysical security.

In the paper, the motif-based approach to behavior pattern description and anomalies in organization staff movement is proposed.

The motif of the employees’ movement represents a combination of the spatial and temporal attributes of the movement enforced by attributes of the visited controlled zone.

The usage of motifs enables transformation of the raw logs from the proximity sensors of the access control system containing only identifiers of the controlled zones into semantically meaningful list of the activities.

This approach is demonstrated with an application to the 2016 VAST Mini-Challenge 2 data set, which describes movement of the employees within organization building.
