The use of an e-management system personal data (EMSPD) in an electronic government environment is important for ensuring the security of the state's information space, combating crime in Azerbaijan and abroad, and increasing economic power. The EMSPD formulates general principles to consistently identify privacy risks and manages data responsibly. In order to determine the importance of the EMSPD in assessing social credit on the basis of the behavior and personal data of citizens, the article provides a brief overview of the EMSPD and a general architectural scheme of the system. To ensure the efficient operation and safety of the EMSPD, first of all, the problems of big data collected in the system generated each second are identified. The study proposes using big data technologies for efficient data collection, storage and processing, as well as using distributed data processing technology in this regard. As a result of the study, the importance and future prospects of the EMSPD in the modern e-government environment are identified. The study uses the methods of systematization, classification, generalization and comparative analysis. The research results can be used for more effective management of e-government (pp.67-76).
