[economic Daily Jin Guanping: activating data value in Compliance use]-according to a commentary article in the Economic Daily, data are listed as the "fifth largest factor of production" after land, labor, capital, and technology, and public data is a breakthrough in the reform of market-oriented allocation of data elements. The application of public data circulation needs to be open and secure as a whole, and security runs through the whole process of data opening. Under the premise of protecting personal privacy and ensuring public safety, it is necessary to ensure that "the original data is not out of the domain, and the data is available and invisible". In recent years, local laws and regulations have been issued in many places to refine the implementation of programs and measures, pay attention to the distinction between the boundaries of public data and personal information, and strengthen the supervision of data collection, storage, use and destruction. All localities should clarify the security management responsibilities of big data management departments, data openness subjects, and data users, implement data review and security assessment, establish and improve the security emergency response mechanism for the opening of public data, clarify the handling of violations of laws and regulations, and promote openness and sharing in the way of the rule of law, so that public data can better benefit the people.
