The chapter provides an overview of existing methodologies, as well as research areas related to the implementation of the potential of artificial intelligence (AI) as a tool for detecting the fixation and further use of information, which may later have evidentiary value in criminal law enforcement. The use of AI as an auxiliary technology in police activities, in the fight against crime, as well as cybercrime, is of great importance and significantly accelerates the process of obtaining relevant information. The aim of the study was to assess the existing methods at the present stage of development of AI, the prospects of development and use in the criminal justice system, to analyze the current state of information technologies for the detection of criminally significant information in the Russian law enforcement system, to explore the potential of AI in the collection of evidence for criminal justice, and to assess the prospects for the development of AI in the field of forensic profiling. Prospective implementation of emotion recognition technologies, assessment of the reli-ability of the information provided to identify potential threats, will simplify and facilitate the work of law enforcement agencies. The use of innovative technologies of AI in the field of law enforcement makes it necessary to increase the level of professional literacy, of both employees and the popula-tion. In the future, the development of AI in the field of law enforcement creates new approaches to information security, and therefore, there will be a need to adapt the legal framework. © 2021 Information Age Publishing.
