Opening the summary of the Office of the Leading Group for Digital Prosecutorial Work of the Supreme People's Procuratorate in 2023, an urgent sense of urgency arrived - in January, a national video symposium on digital prosecutorial work was organized to clarify the functional positioning and target direction of digital prosecutorial work. In February, the organization held a forum on "Methodology of Big Data Legal Supervision" and held on-site observation and learning activities for digital prosecution work. In June, the first national digital prosecutorial training course was held to provide specialized training on key and difficult issues, model applications, and other aspects of digital prosecutorial work. In August, a national competition on big data legal supervision models for procuratorial organs was organized. In October, a national conference was organized to promote digital prosecutorial work in procuratorial organs. "To change our mindset, prosecutors need to enhance their digital thinking. The core function of the" model "- the pursuit and prosecution of omissions and crimes - is already relatively complete. We are considering how to extend the functions of the model, such as carrying out source of prosecution governance and reverse execution linkage." Just after the Spring Festival holiday, Wang Xuepeng, Deputy Director of the Second Prosecutor's Department of Changping District Procuratorate in Beijing, calculated how to expand the functions of the model. The model mentioned by Wang Xuepeng is a big data legal supervision model for cases involving "two cards" that involve omissions and crimes. After sorting out the "two card" cases handled by the court (illegal rental, sale, buying and selling of mobile phone cards and bank cards), it was found that these cases have obvious cross regional characteristics, and people in a fraud gang are often arrested and tried by judicial authorities in different places. After arriving at the case, the suspect often evades the heavy and takes the light, and does not make a statement about his past behavior, which is prone to the phenomenon of missing people and cards. In order to effectively use the decentralized and fragmented data of criminal cases involving "two cards", the hospital has built the above legal supervision model, taking the information of cases involving "two cards" as the source of big data, registering the citizen ID number, telephone number, name, nickname, etc. of suspect and upstream and downstream associated persons, and realizing the intelligent collision comparison of background information through artificial intelligence to achieve automatic concatenation, prompt Query and other functions are used to connect the entire chain of telecommunications fraud cases. At the beginning of 2023, the Beijing Procuratorate will promote the model to be applied to the procuratorial organs throughout the city. As of the end of 2023, using this model, the Beijing procuratorial organs have discovered a total of 37 cross district cases, identified 25 card trafficking gangs, and pursued and prosecuted 124 missing suspects. This model won the first prize in the 2023 National Procuratorate Big Data Legal Supervision Model Competition. "In the era of big data, prosecutors first need to change their mindset, establish digital thinking, consciously transform the information carried by case evidence into data in the legal supervision model, achieve the transformation from evidence to data, and thus build a big data legal supervision model."
