Abstract:The principle of purpose limitation is a fundamental principle of data protection law, whose logical starting point is the right to self-determination of personal information, and has an important balancing function in the value system of protecting innovation and preventing risk. In China’s personal information protection law system, the principle of purpose limitation contains three aspects of clear and reasonable purpose, directly relevant processing, and minimal impact on the rights and interests of individuals. The purpose limitation principle, as a general clause, is abstract and vague, and there are difficulties in its application. In this paper, we adopt the concretization method of general clauses, combined with the analysis of typology theory, and explore the specific rules for the application of the purpose limitation principle from the direction of legislative, administrative, and judicial value supplementation and concretization of the purpose limitation principle. |
