US Patent 12026240 Delegated authentication systems and techniques

Systems and methods may be used to authenticate a user using a first device (e.g., a collaboration device) and a second device (e.g., a device proximate to the collaboration device) For example, the first device may compare an authentication image of a user (captured by the second device) to an image captured by the first device (for example at a lower resolution or with a partial view). The user may be authenticated by the first device in response to identifying the user from the authentication image (e.g., by matching the authentication image to a reference image of the user) and determining a correlation between the authentication image and the captured image.
