配备内置摄像头的便携式移动设备的无处不在导致了数字图像捕获、共享和存档的方式和时间的转变。社交聚会、公共活动甚至犯罪现场的照片和视频在网上司空见惯。虽然这些设备提供的自发性带来了新的个人和创意渠道，但旁观者(实际上，在某些情况下，不情愿的对象)对隐私的担忧在很大程度上仍然没有得到解决。我们提出了i-Pic，这是一个集成了数字捕获和用户定义隐私的可信软件平台。在i-Pic中，用户基于社交环境(例如，在公共场所与朋友在一起还是在工作场所)选择一定级别的隐私(例如，是否允许图像捕获)。附近用户的隐私选择通过短距离无线电进行广告，符合i-Pic标准的捕获平台生成经过编辑的媒体，以符合图像对象的隐私选择。I-Pic使用安全多方计算来确保用户的视觉特征和隐私选择不会被公开泄露，无论他们是否为图像捕获的对象。同样重要的是，i-Pic保留了捕获和在可信用户之间共享的易用性和自发性质。我们对i-Pic的评估表明，可以使用现有的硬件来构建和部署一个实用的、节能的系统，该系统符合场景中许多用户的隐私选择。
The ubiquity of portable mobile devices equipped with built-in cameras have led to a transformation in how and when digital images are captured, shared, and archived. Photographs and videos from social gatherings, public events, and even crime scenes are commonplace online. While the spontaneity afforded by these devices have led to new personal and creative outlets, privacy concerns of bystanders (and indeed, in some cases, unwilling subjects) have remained largely unaddressed. We present I-Pic, a trusted software platform that integrates digital capture with user-defined privacy. In I-Pic, users choose alevel of privacy (e.g., image capture allowed or not) based upon social context (e.g., out in public vs. with friends vs. at workplace). Privacy choices of nearby users are advertised via short-range radio, and I-Pic-compliant capture platforms generate edited media to conform to privacy choices of image subjects. I-Pic uses secure multiparty computation to ensure that users' visual features and privacy choices are not revealed publicly, regardless of whether they are the subjects of an image capture. Just as importantly, I-Pic preserves the ease-of-use and spontaneous nature of capture and sharing between trusted users. Our evaluation of I-Pic shows that a practical, energy-efficient system that conforms to the privacy choices of many users within a scene can be built and deployed using current hardware.
