基于Alt-Geohash编码的k-匿名位置隐私保护方案
k-anonymous location privacy protection scheme based on Alt-Geohash coding
摘要
Abstract
When protecting the location privacy of users who enjoy LBS,traditional k-anonymity techniques often fail to com-prehensively consider time costs and location context during anonymization processes.To address this issues,this paper pro-posed 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 con-struction of high location entropy.Furthermore,it enhanced the dispersion of the anonymous set by applying the Haversine for-mula.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.关键词
