CSPC: A Context-Sensitive Personalized Collaborative Location Privacy Preserving Method

Abstract

Abstract. This paper proposes a decentralized cloaking region creation approach to protecting location privacy. The cloaking region is formed through collaboration to hide the precise position of the location based service requestor. A mobile user can set personalized anticipated and minimum privacy requirements respectively according to different contexts. The anticipated parameters will be satisfied if the time is allowed. Otherwise, the system will pursue the minimum standards for privacy requirements. This approach can satisfy k -anonymity, l -diversity and cloaking granularity simultaneously for privacy preserving.
