Justification of the Legitimacy of Property Rights in Data

In today's digital economy, data plays an increasingly important role in modern society. However, with the widespread use of data, the issue of data rights has gradually attracted attention. As an object of labor, data can provide a reasonable argument for the legitimacy of data property rights based on the Lockean labor property theory. At the same time, data can also be regarded as the projected object of individual will, and Kant's theory of will projection provides a legal basis for data property rights. In addition, Rawls' theory of distributive justice can deeply explain and emphasize the justification of data property rights. This paper emphasizes the legitimacy of data property rights, analyzes the structure of the subject of the right of data property rights, argues the object of data property rights, which mainly includes information, data derivatives and services, and access rights and use rights of data. It also elaborates the content of the right of data property right, which covers four rights: the right to hold, the right to use, the right to protect and the right to compensation.
