EAGER: TWC: Collaborative: iPrivacy: Automatic Recommendation of Personalized Privacy Settings for Image Sharing

这个项目的目的是研究一个综合的图像隐私推荐系统，称为iPrivacy（图像隐私），它可以有效地自动为新共享的照片生成适当的隐私设置，同时考虑到同一照片中出现的多方的共识。随着智能手机和其他移动设备的日益普及，照片分享变得非常流行。然而，许多人，尤其是年轻的社交网络用户，经常分享自己和朋友的私人照片，而没有意识到这些照片可能会对他们未来的生活造成潜在的影响，因为这些照片可能会被无意的披露和侵犯隐私。虽然一些照片分享平台开始提供隐私配置功能，但由于没有很多用户对隐私有足够的背景知识，这种手动过程对用户来说非常繁琐，而且容易出错。这个项目将解决社交网站上照片分享带来的日益严重的隐私问题，并使数十亿社交网络用户受益。教育与研究的结合，将进一步加强这项计划的广泛影响。将开展一系列教育活动，包括课程开发、学生专业培训和K-12教师网络安全训练营，重点关注弱势群体。该项目将无缝整合来自两个不同领域的专业知识：图像理解和隐私管理，从而形成首个全面和自动的政策推荐系统之一。拟建项目包括以下创新研究。首先，将开发一种多方隐私敏感对象识别算法，该算法将能够自动生成照片中每个人的身份，从而使随后的隐私协调过程自动化。其次，设计一种独特的隐私协调方法，通过分层隐私政策挖掘来了解社区中不同层次的隐私关注，并推荐有效协调同一张照片中出现的多人隐私偏好并适应人们隐私偏好演变的策略。所提出的iPrivacy系统不仅可以充分释放用户侧的隐私配置负担，还可以基于从大规模历史和社会信息中获得的知识来促进更好的隐私实践。

The objective of this project is to investigate a comprehensive image privacy recommendation system, called iPrivacy (image Privacy), which can efficiently and automatically generate proper privacy settings for newly shared photos that also considers consensus of multiple parties appearing in the same photo. Photo sharing has become very popular with the growing ubiquity of smartphones and other mobile devices. However, many people especially young users of social networks often share private photos about themselves and their friends without being aware of the potential impact on their future lives caused by unwanted disclosure and privacy violations. Although some photo sharing platforms start to offering functions of privacy configuration, such manual process could be very tedious for users and also error-prone since not many users have sufficient background knowledge about privacy. This project will address these rising privacy concerns of photo sharing in social sites and benefit billions of social network users. The broader impact of this project will be further enhanced by the integration of education and research. A range of educational activities will be carried out including curriculum development, professional training for students and cybersecurity camp for K-12 teachers, with emphasis to under-represented groups.This project will seamlessly integrate expertise from two different domains: image understanding and privacy management, leading to one of the first comprehensive and automatic policy recommendation systems. The proposed project contains the following innovative researches. First, a multi-party privacy-sensitive object identification algorithm will be developed which will be capable of automatically generating the identity of each human subject in a photo so as to automate the subsequent privacy harmonization process. Second, a unique privacy harmonization approach will be designed, which will conduct hierarchical privacy policy mining to understand different levels of privacy concerns in communities, recommend policies that effectively harmonize privacy preferences of multiple people appearing in the same photo and also adapt to the evolution of people's privacy preferences. The proposed iPrivacy system will not only fully release the burden of privacy configuration at users' side, but will also promote better privacy practice based on knowledge learned from large-scale historical and societal information.
