Patent attributes
A method of verifying whether a user of a device corresponds to a previously authenticated user is disclosed. In some embodiments, a processing system has access to a first image and a second image. The first image is of an identity document comprising an image of the previously authenticated user and data identifying the authenticated user. The identity document has been validated by a trusted authority. The second image is an image captured by the device. The first image is compared to said second image to determine whether they are images of the same user. One of the images is designated as a higher quality image, and stored as a validated image along with an identifier for the previously authenticated user. The validated image may be used in a subsequent verification event. The identifying data is be stored with the identifier, whereby to enable said data to be retrieved in a subsequent verification event.
