Abstract

The current privacy-preserving researches are based on the relational data model. However, the existing privacy data models based on the relational model exist some shortcomings. First, they are not enough for protection of composite privacy object. The current researches focus on the privacy data of individual and do not consider how to protect the relationship among several privacy objects. The relationship is also a type of privacy data of each individual. Second, the rapid increasing view make it is difficult for the privacy database administrator to manage the privacy database effectively. In this paper, a privacy data model based on deputy mechanism is proposed for solving those problems. The model can depict the generalization relationship among different privacy objects and provide a stronger hiding capability that IS-A relationship. Moreover, compared with object-oriented data model, the model pays more attention to the storage and usage of privacy data objects in the context of database. Finally, this paper illustrates how to implement the privacy model in the object deputy database management system.
