Research progress of government data identification technology and the next generation government data identification system

Government data identification is a fundamental work in building a national integrated government big data system.This article reviewed the research progress of data identification technology, compared the similarities and differences in coding rules of different data identification technologies, and further reviewed the progress of government data identification and its applications.Based on the clear rights and responsibilities, high security requirements, and strong compatibility requirements of government data, the next generation government data identification system Gcode was proposed.Gcode consists of three parts: external code, internal code, and security code.Among them, the external code was compatible with the Code for Unified Social Information, the internal code established an association relationship of ＆quot;institution-departmentsystem-data＆quot;, and the security code achieved anti-counterfeiting verification by introducing blockchain technology.Gcode has clear rights and responsibilities, st
