As a key technology of the “Fourth Industrial Revolution”, artificial intelligence has shown great potential and advantages in the field of criminal intelligence research and judgment, and its value is deeply reflected in the logical level of application possibility, application necessity, application dimension and so on. In terms of the possibility of application, the natural fit between the mechanism of artificial intelligence itself and the characteristics of information and extensibility of criminal intelligence creates the possibility of application of artificial intelligence in the field of intelligence information research and judgment; The necessity of application includes making technology with technology, reducing dimension and improving efficiency; The application dimension reflects the excellent ability of artificial intelligence in data search, data depth analysis, data breadth analysis, data space-time analysis and so on. However, there are many security risks in the application of artificial intelligence in criminal intelligence, such as over-reliance on automation technology and neglect of traditional basic intelligence collection, influence of transparency and types of algorithms on intelligence search and analysis results, data and privacy security threats. In this regard, the author tries to effectively “defend” from the construction of new intelligence research and judgment system, the development of core algorithm computing power oriented by intelligence research and judgment demand, and the protection of technical regulation and security management, so as to promote the criminal intelligence research and judgment along the artificial intelligence track to play a greater role.
