Abstract

With the development of the 5th Generation Mobile Communication Technology (5G), the 5G network can more accurately locate the user's location. This enables location-based services to provide users with more personalized services, but it also brings more challenges to user location privacy protection. Aiming at the leakage of location privacy and query privacy in LBS, a LBS privacy protection scheme based on searchable encryption is proposed. The scheme uses thresholds to replace the private information queried by users, thereby reducing the risk of location information leakage during user service requests; it reduces the storage space of the server through attribute-based encryption and improves query efficiency. Finally, the correctness of the ciphertext search of the scheme is proved.
