Title: (EN) Method and device for securely sharing images across untrusted channels
(ZH) 用于跨越不受信任的信道安全地共享图像的方法和设备
Abstract: front page image
(EN) A method and device for securely sharing images across untrusted channels includes downloading an encrypted image from a remote server to a computing device. The encrypted image may be encrypted at the time of uploading by another user. The current user of the computing device is authenticated using a facial recognition procedure. If the current user is authenticated and is determined to be authorized to view the decrypted image, the encrypted image is decrypted and displayed to the user. If the user becomes unauthenticated (e.g., the user leaves the computing device or another user replaces the current user), the encrypted image is displayed in place of the encrypted image such that the decrypted image is displayed only for authorized persons physically present at the computing device.
(ZH) 用于跨越不受信任的信道安全地共享图像的方法和设备包括:将加密的图像从远程服务器下载到计算设备。加密的图像可以在由另一个用户上传时进行加密。通过使用面部辨别程序来对计算设备的当前用户进行认证。如果当前用户被认证并被确定为经授权来观看解密的图像,则对加密的图像进行解密并将其显示给用户。如果用户变成未经认证的(例如,用户离开计算设备或另一个用户取代当前用户),则显示加密的图像来代替加密的图像,使得仅针对物理地存在于计算设备处的经授权的人员显示解密的图像。
