Data right is of immeasurable implication for common life of the mankind. In this report，we will discuss the legal basis of the data right and prove the basis for the philosophical appropriateness of the data right through a comparison with human rights and property rights，so as to demonstrate the possibility，necessity and inevitability of establishing the data right system. Currently，the General Provisions of Civil Laws，the Network Security Lawand other laws still describe the “data right” in an ambiguous and discrete manner and don't establish the data right system and uniform legal framework. In this report，we will preliminarily propose the basic assumption for the data right system. On this basis，we will envisage the legislative framework for the “Data Right Law” in order to accelerate the legislative process of data right and construct a new order of digital civilization.
