Abstract: In the era of digital economy,the comprehensive digitization of personal information has become an increasingly obvious phenomenon,and the data value of personal information,especially the proportion of commercial value,has increased sharply.How to coordinate and deal with the conflict of rights and obligations among relevant legal subjects and the expansion of data power,and how to protect the data security of personal information have become important issues.Although the laws and regulations of personal information have basically taken shape,the national economic and social development still requires the strengthening of relevant legal protection and relief,and the construction of relevant mechanisms as well.These mechanisms should include strengthening the technical guidance of data traceability through the extension and expansion of the concept of data traceability,using the western data trust model for reference to establish a static and dynamic personal information data trust "firewall",and standardizing the power boundary to break the monopoly of data power.At the same time,we should build a strong "security barrier" of personal information data chain with the comprehensive coverage of norms and mechanisms.That is to say,our country should provide comprehensive legal norms for personal information from multiple levels,fields and stages,and achieve the purpose of coordinating,protecting and promoting personal information through legislation,judicature and law enforcement.
