基于位置服务中时空关联的隐私保护方案
Spatio-temporal aware privacy-preserving scheme in LBS
摘要
Abstract
Location-based service (LBS) brings a lot of conveniences in people's daily life, but the conveniences are ac-companied with the leaking of privacy. A dummy-based location-preserving scheme was proposed, which took the corre-lation between spatial issues and temporal issues into account. Two algorithms were included in this scheme, map divid-ing algorithm and dummy contents determining algorithm. The map dividing algorithm divided the map into discrete lo-cation cells by Voronoi Diagram to ensure these discrete location cells were not adjacent to each other. The dummy con-tents determining algorithm replaced the query content in previous moment by the intending location in next moment, which efficiently avoided the adversary inferring mobile users' sensitive information according to the correlation between spatial issues and temporal issues. The simulation experiments show that the proposed scheme is effective and efficient.关键词
