Construction and application of logic model for telecom network fraud case investigation based on big data

Telecom fraud, as a new means of fraud emerging in the new era, has a very deep impact on People's Daily life and social development. Therefore, it is necessary to use big data to carry out telecom fraud crime investigation activities to adapt to the changing social environment faster. According to the analysis of accumulated experience in the investigation of telecom network fraud cases in recent years, it can be seen that the case investigation mechanism is limited, the on-site collection of evidence is more difficult, and the cross-border arrest cooperation is more difficult. All these problems directly affect the investigation efficiency and quality of telecom network fraud cases in China. Therefore, some scholars proposed to use big data technology to improve the forensics process, build a cross-border reconnaissance cooperation platform, improve the efficiency of on-site forensics and investigation, and strengthen the effective crackdown on criminal and illegal behaviors. On the basis of understanding the development status of big data technology platform, this paper clarified the corresponding logic model according to the investigation process of telecom network fraud cases, and put forward the application countermeasures with big data technology as the core.
