摘要

Mobile intelligent devices are widely used in our daily lives. User private information can be easily accessed by mobile apps, which are facing fierce threats. Although Android offers a native permission mechanism and there are many security assistants or research works focus on improving privacy protection, there is still a gap on the context aware and personalized authorization for user requirements. We design and implement a novel authorization mechanism on Android which takes into account both user preference and context This video describes a fictitious romantic story to show the inspiration behind our design. The story shows the threats we are facing in the mobile scenarios and the gap between existing solutions and user privacy demands. A brief introduction of our model is also given in the video, including the outline of our design and a short clip which shows the evaluation of our prototype implementation on real device.
