第9届IEEE International Conference on Internet of Things (iThings2016) 会议于2016年12月15日至18日在成都召开。实验室研究生刘天元在会上展示了实验室制作的视频《A Beautiful Story behind the Battle of Privacy》。

该视频主要展示了一种Android上环境敏感的隐私保护机制，以应对移动智能设备上日益严重的隐私威胁同时降低用户的使用难度。视频以一个故事的形式介绍了该机制的设计初衷，并展示了其基本框架。

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.
