Location Anonymity Method for Continuous LBS Requests
Hongzhou Shi · Jisuanji gongcheng · 2011
Location cloaking in terms of continuous Location-Based Services(LBS) request need to consider how to avoid the attack by correlating anonymity areas of different requests from the same user.In term of this privacy problem,this paper proposes an improved k-anonymity model on basis of the traditional k-anonymity model,and designs a state-of-art location anonymity framework and algorithms for continuous LBS requests.This framework guarantees the best Quality of Service(QoS) and good response time of system as well as meeting the privacy requirement.Analysis results show that the method can make better use of the system resources and thus decrease the response time of user's requests.
