报告简介:Smart devices and mobile apps are rolling out at swift speeds over the last decade, turning these devices into convenient and general-purpose computing platforms. However, smart devices also bring risks of privacy leakage. Sensory data collected from smart devices are important resources to nourish mobile services, and they are regarded as innocuous information which can be obtained without user permission and awareness. In this talk, two privacy issues caused by sensory data collected from smart devices will be addressed. The first one is location privacy leakage. The second one is deep learning based inference of private information. For the first issue, it is shown that only by using the data collected from the embedded sensors in smart devices instead of GPS data, a user's location information can be inferred with high accuracy. For the second issue, it is shown that the seemingly innocuous sensory data could help with infer users' tap positions on the screens of smart devices by employing some deep learning techniques. The tap stream profiles for each type of apps can then be derived so that a user's app usage habit can be accurately inferred. Furthermore, it is shown that users' app usage habits and passwords may be inferred with high accuracy.
