摘要:

像Android这样的现代移动平台使应用程序能够读取手机上的总用电量。这些信息被认为是无害的,阅读它不需要用户许可或通知。我们表明,通过简单地读取手机的总功耗在一段时间内的几分钟的应用程序可以了解有关用户的位置信息。由于大量组件和应用程序同时消耗功率,因此聚合电话功耗数据非常嘈杂。然而,通过使用机器学习算法,我们能够成功地推断出手机的位置。我们讨论了几种可以补救这种隐私泄露的方法。

英文摘要:

Modern mobile platforms like Android enable applications to read aggregate power usage on the phone. This information is considered harmless and reading it requires no user permission or notification. We show that by simply reading the phone's aggregate power consumption over a period of a few minutes an application can learn information about the user's location. Aggregate phone power consumption data is extremely noisy due to the multitude of components and applications that simultaneously consume power. Nevertheless, by using machine learning algorithms we are able to successfully infer the phone's location. We discuss several ways in which this privacy leak can be remedied.
