基于多匿名器架构的用户位置双重隐私保护算法
Double Privacy Protection Algorithm for User Location Based on Multi-anonymizer Architecture
摘要
Abstract
With the proliferation and development of Location-Based Services(LBS),the privacy protection of user location data has become an urgent issue.Existing anonymity-based privacy protection methods face challenges related to the semantic in-formation in anonymous locations and query content affecting anonymity security.To address this,we propose a Dual Privacy Pro-tection Algorithm Based on Multi-Anonymizer Architecture(MAA-DPPA),utilizing a verifiable secret sharing algorithm.Un-like existing algorithms,MAA-DPPA enhances location privacy by integrating location anonymity with encrypted queries.Ini-tially,a verifiable secret sharing and multi-anonymizer query encryption algorithm is introduced to enhance query security.Fur-thermore,an anonymization method is designed to improve semantic location privacy by satisfying individual semantic diversity and replacing sensitive semantic locations.Experimental results demonstrate that this algorithm achieves the highest level of pri-vacy.The average improvement percentage range of MAA-DPPA compared to algorithms based on road network semantic diver-sity anonymous set construction under multiple conditions is 38.3%～59.8%,and compared to algorithms based on semantic and trade-off perception,the improvement range is 51.1%～76.5%.MAA-DPPA significantly enhances privacy protection while im-proving algorithm efficiency,verifying its effectiveness in safeguarding user location privacy.关键词
