A Privacy-Aware Access Model on Anonymized Data

With development of information technology and communication, corporations and individuals will collect some digital information to support information-based decisions. However, under some conditions, if all original data are released, some privacy will be disclosed, which will threaten data security and data privacy. Therefore, data owners will take some security measures. Role-based access control may authorize related original data accessed by users according to their roles. Privacy-preserving technology release processed data to avoid privacy disclosure. Nevertheless, existing privacy-preserving technologies lack continuity and are quite inefficient. This paper establishes an access model about on anonymized data and combines with the foregoing two security measures. On the premise that data security and data privacy are ensured, there is more flexibility and diversity and work efficiency is improved as well.
