Development of Algorithms to Identify, Disclose, and Investigate High Tech Crimes of an Extremist Nature Committed Via the Internet

This article examines the most important problems arising in the detection, disclosure, and investigation of high tech extremist crimes committed through use of the Internet. The main source of legal errors is found through the identification of mandatory and optional signs of crimes of this type according to their deployed criminal legal characteristics, have been revealed. The specific features of seven groups of algorithms are described, on the basis of which proper information support of all kinds of investigative actions can be created. The specifics of this system of algorithms, within an interactive expert framework, allow investigators to receive necessary information support in real time.
