视觉内容隐私保护:一项调查

Visual Content Privacy Protection: A Survey

Ruoyu Zhao, Yushu Zhang, Tao Wang, Wenying Wen, Yong Xiang, Xiaochun Cao

摘要:

视觉是人类最重要的感官,也是人类认知的主要方式之一。因此,人们倾向于利用视觉内容来捕捉和分享他们的生活经历,这极大地促进了信息的传递。同时,它也增加了侵犯隐私的风险,例如,图像或视频可以揭示不同种类的隐私敏感信息。研究人员一直在不断努力开发有针对性的隐私保护解决方案,有几项调查从某些角度进行了总结。然而,这些调查要么是问题驱动的,要么是特定的,要么是特定的技术,这使得他们很难从宏观上总结现有的解决方案。在这项调查中,提出了一个框架,包括各种问题和解决方案的视觉隐私,这使得从一个全面的层面上对隐私问题的宏观理解。它基于隐私关注有对应的敌手这一事实,将隐私保护分为基于计算机视觉(CV)敌手、基于人类视觉(HV)敌手和基于CV \HV敌手三类。对于每一个类别,我们分析了隐私保护的主要方法的特点,然后系统地审查代表性的解决方案。还讨论了视觉隐私保护面临的挑战和未来的发展方向。

英文摘要:

Vision is the most important sense for people, and it is also one of the main ways of cognition. As a result, people tend to utilize visual content to capture and share their life experiences, which greatly facilitates the transfer of information. Meanwhile, it also increases the risk of privacy violations, e.g., an image or video can reveal different kinds of privacy-sensitive information. Researchers have been working continuously to develop targeted privacy protection solutions, and there are several surveys to summarize them from certain perspectives. However, these surveys are either problem-driven, scenario-specific, or technology-specific, making it difficult for them to summarize the existing solutions in a macroscopic way. In this survey, a framework that encompasses various concerns and solutions for visual privacy is proposed, which allows for a macro understanding of privacy concerns from a comprehensive level. It is based on the fact that privacy concerns have corresponding adversaries, and divides privacy protection into three categories, based on computer vision (CV) adversary, based on human vision (HV) adversary, and based on CV \& HV adversary. For each category, we analyze the characteristics of the main approaches to privacy protection, and then systematically review representative solutions. Open challenges and future directions for visual privacy protection are also discussed.
