隐私智能:在线社交网络图像隐私研究综述

Privacy Intelligence: A Survey on Image Privacy in Online Social Networks

Chi Liu, Tianqing Zhu, Jun Zhang, Wanlei Zhou

AI总结:

该综述针对在线社交网络图像分享的隐私风险与现有保护方案的不足,从用户视角提出隐私智能分析框架,梳理相关智能解决方案并展望未来方向。

摘要:

在线社交网络(OSNs)上的图像分享已成为日常社交活动不可或缺的一部分,但这也导致隐私侵犯风险上升。近期热门OSN服务发生的图像泄露事件,以及利用先进算法(如DeepFake)滥用个人照片的现象,促使公众重新思考OSN图像分享场景下的个人隐私需求。然而,OSN图像隐私本身十分复杂,现实中现有的隐私管理解决方案不足以提供个性化、准确且灵活的隐私保护,人们亟需一个更智能的环境,实现兼顾隐私的OSN图像分享。为填补这一空白,我们提出“隐私智能”方向的综述,从以用户为中心的视角,针对动态OSN图像分享中的现代隐私问题展开研究。具体而言,我们给出了OSN图像隐私的定义与分类体系,并基于OSN图像分享的生命周期提出了高层隐私分析框架。该框架包含三个阶段,各阶段遵循不同的隐私设计原则。在每个阶段中,我们识别了OSN图像分享中的典型用户行为,以及与这些行为相关的隐私问题。随后,我们同样按阶段划分,对针对这些隐私问题的代表性智能解决方案进行了系统综述。最终的分析构建了一套用于闭环隐私管理的智能隐私防火墙。我们还讨论了该领域面临的挑战与未来方向。

英文摘要:

Image sharing on online social networks (OSNs) has become an indispensable part of daily social activities, but it has also led to an increased risk of privacy invasion. The recent image leaks from popular OSN services and the abuse of personal photos using advanced algorithms (e.g. DeepFake) have prompted the public to rethink individual privacy needs in OSN image sharing. However, OSN image privacy itself is quite complicated, and solutions currently in place for privacy management in reality are insufficient to provide personalized, accurate and flexible privacy protection. A more intelligent environment for privacy-friendly OSN image sharing is in demand. To fill the gap, we contribute a survey of "privacy intelligence" that targets modern privacy issues in dynamic OSN image sharing from a user-centric perspective. Specifically, we present a definition and a taxonomy of OSN image privacy, and a high-level privacy analysis framework based on the lifecycle of OSN image sharing. The framework consists of three stages with different principles of privacy by design. At each stage, we identify typical user behaviors in OSN image sharing and the privacy issues associated with these behaviors. Then a systematic review on the representative intelligent solutions targeting those privacy issues is conducted, also in a stage-based manner. The resulting analysis describes an intelligent privacy firewall for closed-loop privacy management. We also discuss the challenges and future directions in this area.
