位置大数据服务中基于差分隐私的数据发布技术
Location publishing technology based on differential privacy-preserving for big data services
摘要
Abstract
Aiming at dealing with prospect knowledge and complex combinatorial attack, a new location big data pub-lishing mechanism under differential privacy technology was given. And innovative usability evaluation feedback mechanism was designed. It gave corresponding solution details for the sensitive attributes and the identity recognition to analyze the quality of service, aimed at privacy protecting for location based big data under situations like combination of location information and non-location information and attacker’s arbitrary background knowledge. Simulation results based on different spatial indexing technology proved that the new publishing model has a higher accuracy under speci-fied privacy conditions for the location query service.关键词
