ABSTRACT

The rapid development of big data technology has profoundly changed the landscape of criminal investigation. As a result, the big data criminal investigation model has emerged and become a key force in promoting the modernization of criminal justice. This paper conducts an in-depth analysis of the big data crime investigation model, elaborates on the characteristics of diversity, predictability, and correlational thinking it presents in the evolution of data thinking, and introduces key technologies such as crime data retrieval, collision, extraction, profiling, and relationship analysis that underpin this model. It also proposes establishing and improving compliance mechanisms (e.g., data collection, retrieval, review, supervision, and privacy protection) to ensure effective operation. The big data crime investigation model drives innovation in investigative concepts and methods, providing strong data support for investigative activities. Through optimizing concepts, technologies, and mechanisms, it will advance investigative work toward modernization, legalization, and intelligence.
