近年来，高精度定位设备使我们能够提供各种类型的基于位置的服务。另一方面，由于此类位置数据包含深度个人信息，位置隐私的保护是基于位置的服务中最重要的问题之一。在本文中，我们提出了一种匿名通信技术来保护基于位置的服务用户的位置隐私。在我们提出的技术中，此类用户生成多个虚假位置数据（虚拟），并将其与用户的真实位置数据一起发送给服务提供商。由于服务提供商无法区分真实位置数据，因此用户位置隐私受到保护。我们还描述了一种降低客户端和服务器之间通信成本的技术。此外，我们使用实际位置数据对我们提出的技术进行了性能研究实验。实验结果表明，我们提出的技术保护了人们的位置隐私，并且可以充分降低通信成本，从而使我们的通信技术可以应用于实际的基于位置的服务。
Recently, highly accurate positioning devices enable us to provide various types of location-based services. On the other hand, because such position data include deeply personal information, the protection of location privacy is one of the most significant problems in location-based services. In this paper, we propose an anonymous communication technique to protect the location privacy of the users of location-based services. In our proposed technique, such users generate several false position data (dummies) to send to service providers with the true position data of users. Because service providers cannot distinguish the true position data, user location privacy is protected. We also describe a cost reduction technique for communication between a client and a server. Moreover, we conducted performance study experiments on our proposed technique using practical position data. As a result of the experiments, we observed that our proposed technique protects the location privacy of people and can sufficiently reduce communication costs so that our communication techniques can be applied in practical location-based services.
