Abstract: The development of information technology leads to rapid increment of personal data amount, and how to efficiently manage personal data becomes a serious problem day by day. This paper firstly introduces the related concepts of personal data management, makes comparisons between personal data management and enterprise data management, and proposes a user-centered system framework for managing personal data. Based on surveying the existing works on personal data model, data integration, data storage, data query, data security, privacy protection, evaluation technology and system implementation, this paper proposes graph-based personal dataspace model, self adaptive data integration method, multi-level storage policy and user memory rules-based query policy. This paper finally makes an outlook of future works.
