位置共享服务正变得越来越受欢迎。尽管许多位置共享服务允许用户设置隐私策略来控制谁可以访问他们的位置,但服务提供商的使用仍然是一个令人担忧的问题。理想情况下,位置共享提供商和中间件不应该在未经用户同意的情况下访问用户的位置数据。在本文中,我们提出了一个新的位置共享协议,称为经度,可以盲目地共享用户的位置数据,并允许用户控制谁可以访问她的位置,什么时候和什么程度的精度,从而减轻隐私问题。底层加密算法是为支持GPS的移动的电话设计的。我们描述和评估我们的Nexus One Android移动的手机的实现。
Location sharing services are becoming increasingly popular. Although many location sharing services allow users to set up privacy policies to control who can access their location, the use made by service providers remains a source of concern. Ideally, location sharing providers and middleware should not be able to access users’ location data without their consent. In this paper, we propose a new location sharing protocol called Longitude that eases privacy concerns by making it possible to share a user’s location data blindly and allowing the user to control who can access her location, when and to what degree of precision. The underlying cryptographic algorithms are designed for GPS-enabled mobile phones. We describe and evaluate our implementation for the Nexus One Android mobile phone.
