Abstract

When protecting the location privacy of users who enjoy LBS, traditional k-anonymity techniques often fail to comprehensively consider time costs and location context during anonymization processes. To address this issues, this paper proposed a KLPPS-AGC. Firstly, utilizing location generalization and Alt-Geohash encoding technique enabled rapid retrieval of historical data. Secondly, selecting locations with high location entropy based on historical query probabilities enabled the construction of high location entropy. Furthermore, it enhanced the dispersion of the anonymous set by applying the Haversine formula. Lastly, this paper built a secure anonymous set to protect user's location privacy. Experiments show that this scheme has lower time cost and higher privacy.
