Conclusion
In this Efficient and Privacy-Preserving Polygons Spatial Query Framework for Location-Based Services paper, we have proposed an efficient and privacypreserving polygons spatial query framework for LBSs, named Polaris. Based on an improved efficient homomorphic encryption technology over composite order group, the proposed Efficient and Privacy-preserving Polygons Spatial Query Framework Polaris can achieve query polygons privacy preservation and confidentiality of LBS data. Specifically, for an LBS query request from a registered LU, the LBS query execution is directly performed over ciphertext on CS without decryption, and the result of LBS query can only be decrypted by LU. Thus, LU can get accurate LBS query result without divulging his/her query information. Detailed security analysis shows its security strength and privacy-preserving ability, and extensive experiments are conducted to demonstrate its efficiency. In this system project paper, we present an efficient and privacy-preserving polygons spatial query framework for location-based services, called Polaris.
