The right to personal information is a basic human right. Presently, legal protection to personal information in China far from satisfactory, particularly in cloud computing, personal information has been seriously misappropriated and abused. The issue of personal information protection covers and even exceeds the boundaries of different legal departments such as the constitution, administrative law, criminal law and civil law etc. If observed just from a branch law perspective, it is probable that we would attend to one thing and lose the sight of another. As a consequence, we should formulate a consolidated statute to protect our personal information, in which we are supposed to establish the scientific principles, define accurately the subject system as well as elaborate clearly the object system and its pointed objects in the personal information legal relationship, and simultaneously construct reasonable right relief systems to personal information.
