Abstract:

When providing localization services,the untrustworthy of the cloud server may cause the information of the user’s location and the server’s location resources to be leaked,which may arouse privacy concerns.Although some privacy preserving localization schemes have been proposed to protect the user privacy,there is a lack of attention to the privacy of server’s location resources as well as the multi-user setting.Therefore,a secure and efficient multi-setting fingerprinting localization scheme with access control is proposed.A secure exact set similarity search based on ASPE is designed to achieve quick coarse localization.In addition,a lightweight access control strategy based on polynomial function is designed,which can flexibly set the access rights to the maps to prevent unauthorized access by malicious users,and can provide users with different accuracy of localization services.Security analysis shows that the proposed scheme can accomplish the server and user privacy protection.Experiments in the dataset collected in the real-world environments have demonstrated that the proposed scheme can achieve fast coarse localization and accurate location estimation.

Key words: fingerprinting localization, privacy preserving, access control, coarse localization
