A Method and Application for Constructing a Authentic Data Space

Aiming at the growing problems of data asset management, transaction, sharing, etc., this paper proposes a Authentic Data Space model that unified definition of the object's full lifecycle data, fine-grained data security hierarchical protection and business-based full data association. This paper discuss the construction method of Authentic Data Space from the three dimensions of data dimension, business dimension and security dimension, and give the system architecture of Authentic Data Space management system. It provides an effective solution to solve the problem of data asset management, data security and data fusion in big data environment.
