摘要： Users of an online system are authenticated based on signatures of cameras that were used to capture images uploaded to the online system. Users of an online system upload photos taken from their cameras. The online system extracts characteristic information about the camera that captured the photos. This information includes a mapping of faulty pixels, metadata included with the photos, a naming convention, and the like. The online system stores an association between the user and the camera. This association is used for authentication of the user. For authentication, the user is asked to upload new photos taken from the camera that the user used previously. The information extracted from the newly uploaded photos is matched against stored information of cameras used previously by the user. The user is successfully authenticated if the camera used for the newly uploaded photos matches a previously stored camera.
摘要翻译：在线系统的用户基于用于捕获上传到在线系统的图像的相机的签名进行身份验证。在线系统的用户上传从相机拍摄的照片。在线系统提取拍摄照片的相机的特征信息。该信息包括错误像素的映射，照片附带的元数据，命名约定等。在线系统存储用户和相机之间的关联。该关联用于用户的认证。对于认证，用户被要求上传用户以前使用的相机拍摄的新照片。从新上传的照片提取的信息与用户先前使用的相机的存储信息相匹配。如果用于新上传的照片的相机与先前存储的相机匹配，则用户已成功验证。
