独立架构下自适应情境的位置隐私保护方法
Context-aware location privacy protection technique without TTP and user cooperation
摘要
Abstract
Most current privacy-preserving techniques either require a trusted third-party ( TTP ) anonymizer or have proved to be quivering in the users' cooperative stability when temporal-spatial scenes change in located-based service ( LBS ) . In order to address these challenges , this paper introduces an adaptive context-aware privacy-preserving technique without TTP and user cooperation : the context of a user's location can be real-time achieved based on the multi-granularity abstract road-networks from the LBS server . Furthermore , the usage of the context-aware technique ensures adaptability to the user's personalized privacy settings , and enables the LBS server to retrieve the minimal regional road-network and incremental nearest-neighbor results . Theoretical analysis and experimental results validate the technique's effectiveness on LBS accuracy , privacy protection and communication QoS ( Quality -of-Service) .关键词
