On-line sharing of images has become a key enabler of users' connectivity. Various types of images are shared through social media to represent users' interests and experiences. While extremely convenient and socially valuable, this level of pervasiveness introduces acute privacy concerns. First, once shared images may go anywhere, as copying / resharing images is straightforward. Second, the information disclosed through an image reveals aspects of users' private lives, affecting both the owner and other subjects in the image. Malicious attackers can take advantage of these unnecessary leaks to launch context-aware attacks (e.g., spearfishing) or even impersonation attacks. This project is developing methods to help users appropriately control access to their shared images.The investigators are developing new techniques to tackle image privacy based on the image content as well as images and users' meta-data, by (a) inferring the sensitivity of a given image based on the visual properties of the images and the users' image sharing patterns, and then automatically applying the appropriate privacy settings for that image, and (b) by using discovered users' sharing patters to define access policies according to the locally enforceable controls on the domain of interest. Beyond the technical results, this project is developing a framework for understanding the common classes and categories of images with respect to the users' understanding of privacy. This framework will enable an understanding of the images that need protection and help improve user awareness of classes of images that are often unintentionally or accidentally under-protected.

图像的在线共享已成为用户连接性的关键推动者。 各种类型的图像通过社交媒体共享，以表示用户的兴趣和经验。 虽然极为方便且具有社会价值，但这种普遍性的水平引入了急性隐私问题。首先，一旦共享图像就可以到任何地方，因为复制 /重新显示图像很简单。其次，通过图像披露的信息揭示了用户私人生活的各个方面，影响了图像中所有者和其他主题。 恶意攻击者可以利用这些不必要的泄漏来发射上下文感知的攻击（例如，矛盾），甚至是假冒攻击。 该项目正在开发方法，以帮助用户适当控制其共享图像的访问。调查人员正在开发新技术，根据图像内容以及图像和用户的元数据来解决图像隐私，通过（a）（a）推断给定图像的敏感性，根据图像的视觉效果以及使用适当的图像分享图像，然后使用适当的图像设置，并使用该图像分享图像，然后使用该图像进行自动设置（B）根据目的域上的本地可强制执行控件来定义访问策略。 除技术结果外，该项目还开发了一个框架，以了解用户对隐私的理解的常见类别和类别。 该框架将使人们能够了解需要保护的图像，并帮助提高用户对通常是无意间或意外受到保护的图像类别的认识。
