Abstract. The areas within which the technological revolution set in motion by the AI could more significantly impact with the claims of protection of legal assets, entrusted to criminal law, are basically four: law enforcement and, in particular, predictive policing, where AI systems can make an important contribution to combating, or better yet preventing, the commission of crimes; the possible use of decision-making algorithms to resolve criminal disputes, in order to operate a sort of replacement, or at least of juxtaposition, of the judge-man with the judge-machine; the crime risk assessment entrusted to predictive algorithms, able to draw and re-elaborate enormous quantities of data in order to bring out relationships, coincidences, correlations, that make it possible to profile a person and predict his or her subsequent behavior, even criminal; finally, the possible hypotheses of involvement – as a tool, as an author, or as a victim – of an AI system in the commission of a crime. This work aims to illustrate these areas, indicating problems and prospects connected to the use of AI systems.
