当前的协作式照片隐私保护解决方案可以分为两种方法：控制接收者，限制某些观看者访问照片；控制内容，保护照片的全部或部分不被查看。针对后一种方法，我们引入了增强隐私的照片混淆方法，并对271名参与者进行了在线实验，以评估它们对人类识别的有效性以及它们如何影响观看体验。结果表明，模糊和像素化这两种最常见的模糊处理是无效的。另一方面，修复，完全移除一个物体或人，以及化身，用图形表示取代内容是有效的。从观众体验的角度来看，模糊、像素化、修复和化身是更好的选择。基于这些结果，我们建议修复和头像作为照片的隐私增强技术可能是有用的，因为它们都有效地增加了照片元素的隐私，并提供了良好的观看体验。
Current collaborative photo privacy protection solutions can be categorized into two approaches: controlling the recipient, which restricts certain viewers' access to the photo, and controlling the content, which protects all or part of the photo from being viewed. Focusing on the latter approach, we introduce privacy-enhancing obfuscations for photos and conduct an online experiment with 271 participants to evaluate their effectiveness against human recognition and how they affect the viewing experience. Results indicate the two most common obfuscations, blurring and pixelating, are ineffective. On the other hand, inpainting, which removes an object or person entirely, and avatar, which replaces content with a graphical representation are effective. From a viewer experience perspective, blurring, pixelating, inpainting, and avatar are preferable. Based on these results, we suggest inpainting and avatar may be useful as privacy-enhancing technologies for photos, because they are both effective at increasing privacy for elements of a photo and provide a good viewer experience.
