Differential privacy-based cooperative positioning for satellite internet
-
摘要: 卫星互联网基于GNSS为用户提供定位、导航和定时服务，但GNSS协同定位过程会泄露包含用户位置信息的数据从而对用户隐私安全造成威胁. 针对当前GNSS协同定位隐私保护方面存在的问题，本文提出了一种基于差分隐私的卫星导航系统协同定位方法. 该方法首先生成扰动位置，并在满足隐私预算的前提下随机选择扰动位置计算定位协同数据，防止用户位置信息在协作过程中泄露. 实验结果表明：所提出的方法可以在保障定位准确率和实时性的前提下有效保护用户位置隐私，可为卫星互联网协同定位信息安全研究提供理论参考.Abstract: Satellite internet provides positioning, navigation and timing services for the whole world based on the Global Navigation Satellite System (GNSS), but the data containing users’ location information will be leaked during GNSS cooperative positioning process, which poses a threat to users’ privacy security. To address the current privacy-protection challenges in GNSS cooperative positioning systems, this paper proposes a differential privacy-based cooperative positioning method for GNSS systems. The method first generates the perturbed position and randomly selects one to calculate the positioning collaboration data under the premise of satisfying the privacy budget, so as to prevent the user’s location from being leaked during the collaboration process. The experimental results show that the proposed method can effectively protect user location privacy while guaranteeing real-time and accurate positioning service, which provides a theoretical reference for the research of GNSS cooperative positioning information security.
