基于位置服务提出了基于k匿名的混合式隐私保护系统(HPPS),分别阐述了混合式隐私保护系统中分散式和中心式两部分的设计.实验结果表明,当k值增大时,隐私保护程度也在增加,同时兴趣点查询质量和隐私保护之间也达到了一种平衡.
This paper proposes hybrid privacy protection system (HPPS) based on k anonymous, and it expounds the design of the two part of the system that contain the decentralized and centralized architecture. Experimental results show that the level of privacy protection is increasing while the k value increases. At the same time, the query quality of POI and privacy protection has reached a balance.
