Method and device for securely sharing images across untrusted channels

摘要

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 decrypted image such that the decrypted image is displayed only for authorized persons physically present at the computing device.

主权项

1. A method comprising:
downloading an encrypted image and an image of an authorized user to a computing device, the encrypted image including additional information useable to identify the authorized user; receiving an image of a current user of the computing device from a camera communicatively coupled to the computing device; authenticating the current user by performing a facial recognition procedure on the image of the current user using the image of the authorized user to verify that the current user is the authorized user; determining whether the authenticated current user is authorized to view a decrypted image of the encrypted image based on the additional information included with the encrypted image; in response to the authenticated current user being authorized to view the decrypted image, (i) decrypting the encrypted image and (ii) displaying the decrypted image on the computing device; in response to the authenticated current user not being authorized to view the decrypted image, displaying the encrypted image on the computing device; and continually authenticating the user while the decrypted image is displayed on the computing device.
