Analysis of Research Hotspots and Trends in the Field of Information Security Based on CiteSpace

With the help of CITESPACE software, a visual analysis of 598 documents related to the protection of information obtained from sci, EI, CSSCI and CSCD core databases in the Cnki database was carried out, combined with measurement theories in network analysis and evolution of topics, and the results of Network Information Security Research were discussed.The number of papers published in this field tends to grow significantly and there are a large number of scholars and collaborative groups working in this field.The research centers focus on deep study and criminal responsibility in the field of criminal law. In addition, data mining surveys have been conducted to protect privacy and manage the risk of leakage of sensitive information in the context of big data.These results not only reveal existing lines of information security research, but provide a framework for further research into new technological trends such as quantum security, biometric functions, and international cooperative control.
