Privacy-preserving location-aware model based on encrypted data

RAO Jie;TAN Bo;TAN Chengxiang;School of Electronics and Information Engineering,Tongji University;  
The privacy-preserving location-aware model based on encrypted data was proposed to solve the privacy and security problems of Location Based Service(LBS) on the basis of survey of existing models.The spatial data was encrypted by the trusted server of a third party to realize the balance between service and privacy.Meanwhile the extended Discretionary Access Control(DAC) policy was implemented in a way that users are able to selectively share their data with others according to their own privacy concerns.Finally the location based queries were realized by using the improved order-preserving encryption algorithm through data conversion,bucket division and linear mapping.Experiments and analysis show that this model enables user-centric access control and queries on encrypted spatial data.The proposed algorithm improves the computational performance.
