摘要: 摘要:随着基于位置服务(LBS)的普及和发展,用户位置数据的隐私保护已成为一个紧迫的问题。针对现有的基于匿名的隐私保护仍面临匿名位置和查询内容中的语义信息对匿名安全性问题的挑战,基于可验证秘密共享算法提出一种多匿名器架构的双重隐私保护算法(Dual Privacy Protection Algorithm based on Multi-Anonymizer Architecture, MAA-DPPA)。与现有算法不同,该算法通过集成位置匿名和查询加密来增强位置隐私保护。首先,提出可验证秘密共享和多匿名器的查询加密算法,以增强查询安全性。其次,设计一种匿名方法,通过满足个人语义多样性的匿名位置和替换敏感语义位置来增强语义位置隐私。实验结果表明,MAA-DPPA隐私性最高,MAA-DPPA在多个条件下相对于基于道路网络语义多样性的匿名集构造的算法的平均提高百分比范围在38.3%~59.8%,且相对于基于语义和权衡感知的提高范围在51.1%~76.5%,MAA-DPPA算法在提高隐私保护性的同时显著提升了算法效率,验证了其在用户位置隐私保护中的有效性。

Abstract:
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 information in anonymous locations and query content affecting anonymity security. To address this, we propose a Dual Privacy Protection Algorithm Based on Multi-Anonymizer Architecture (MAA-DPPA), utilizing a verifiable secret sharing algorithm. Unlike existing algorithms, MAA-DPPA enhances location privacy by integrating location anonymity with encrypted queries. Initially, a verifiable secret sharing and multi-anonymizer query encryption algorithm is introduced to enhance query security. Furthermore, 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 privacy. The average improvement percentage range of MAA-DPPA compared to algorithms based on road network semantic diversity 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 improving algorithm efficiency, verifying its effectiveness in safeguarding user location privacy.
