摘要 为解决数据共享应用中的隐私保护问题和提高数据共享的可用性,提出一种以用户为中心的隐私保护模型.在该模型中,用户可以通过关键字和特征的选取对隐私信息进行自主设置,并采用基于信任的方法来确定共享数据对象可获得的隐私量.当共享数据中包含的隐私量超过共享对象可获得的范围后,通过替换的方法来保护用户隐私.仿真实验表明,对比基于访问控制的隐私保护法,该模型在数据共享应用中能够有效保护隐私并保证较高的数据共享可用性. To solve the problem of privacy preservation while maintaining a high degree of data sharing in applications,a user-centric privacy preservation model is proposed.In the model,users are allowed to set their privacy through selecting key words and special characteristics and a trust based method is used to determine how much privacy entropy that the data sharing entities can get.If the privacy entropy is out of the range that the data sharing entities can afford,a substitution method is used to help preserve privacy.Simulation results show that the method proposed can protect privacy more effectively than methods based on access control while offering a higher degree of data sharing.
