Research on the Application of Artificial Intelligence in Criminal Investigation and Its Legal Issues

Abstract

With the rapid development of artificial intelligence technology, its application in the field of criminal investigation has become an important direction of change in the investigation model of public security organs. The embedding of AI technologies such as face recognition, big data analysis, and behavior prediction has significantly improved the efficiency of investigation, but it is also accompanied by many legal risks such as privacy infringement, algorithm bias, and lack of procedural justice. Starting from the current status of technology application, this article systematically analyzes the main legal issues faced by artificial intelligence in criminal investigation, including the legal boundaries of personal information protection, the admissibility of AI evidence, and procedural control mechanisms. On this basis, drawing on the legal regulatory experience of the United States, the European Union, Japan, Germany and other countries, it is proposed that my country should establish the boundaries of technology use, strengthen data protection mechanisms, and improve the evidence system and supervision mechanism through legislation to build a legal regulatory system for artificial intelligence criminal investigation that takes into account efficiency and rights protection. The article aims to provide theoretical support and institutional reference for the construction of relevant systems and legal responses in my country.
