Artificial intelligence has affected and is changing our lives, penetrating into all fields of society, and the field of law is no exception. The development of artificial intelligence judicature such as smart court is a positive response of judicial informatization to artificial intelligence technology. Chinese judicature, which has experienced the development of electronization, networkization and digitization, has achieved significant transformation, integration and development in the era of artificial intelligence. At present, artificial intelligence has realized some applications in court system, procuratorate system and public security system, but these applications still remain at the superficial and uniformed level. With the improvement of artificial intelligence optical character recognition technology, natural language processing technology, intelligent speech recognition technology, element extraction technology and machine learning ability, higher-level artificial intelligence judicature urgently needs to be further promoted to run through the whole judicial process of the public security department, the Procuratorate department, the court department, and the Justice department. The data communication between the judicial systems with the data centers should adopt the optical one-way security isolation data automatic import system. The internal network between the judicial system adopts a two-way one-way gatekeeper to build a secure communication network. Based on the Secure network, interconnected and shared data storage, management and Protection platform, convenient transaction processing platform, intelligent legal analysis platform, efficient judicial execution platform, stable judicial supervision platform, extensive legal service platform should be established.
