The anchors in wireless network localization system suffer from the risk of location leakage, which may result in some catastrophic dangers. To preserve the location privacy of anchors, this letter proposes to hide the anchor’s position in range-based localization through a secret sharing method. By decomposing the private input of anchors into several secret shares and concealing it in the constant term of the secret polynomial, the location information of anchors cannot be disclosed by any other node in the network including the server, during the entire localization process. The performance of the proposed scheme in privacy preservation, positioning accuracy and efficiency improvement (i.e., low communication and computation costs) are evaluated through simulations.

通过秘密共享隐藏锚点在基于范围的无线定位中的位置

无线网络定位系统中的锚点存在位置泄露的风险，这可能导致一些灾难性的危险。为了保护锚点的位置隐私，这封信建议通过秘密共享方法在基于范围的定位中隐藏锚点的位置。通过将anchor的私有输入分解为若干个秘密份额，并将其隐藏在秘密多项式的常数项中，在整个定位过程中，包括服务器在内的网络中的任何其他节点都不能泄露anchors的位置信息。通过仿真评估了所提出方案在隐私保护、定位精度和效率提高（即低通信和计算成本）方面的性能。
