User authentication via mobile communication device with imaging system

摘要

A graphical authentication identifier is used to facilitate automatic authentication of a user. A graphical identifier authentication system receives a request from an authenticating entity for a onetime use graphical authentication identifier. In response to the received request, a onetime use graphical authentication identifier to be displayed by the authenticating entity is generated. A request for user authentication information by the authenticating entity is encoded in the graphical authentication identifier, which is transmitted to the authenticating entity for display (e.g., on a login screen). The onetime use graphical authentication identifier being displayed by the authenticating entity is captured by a registered user operated computing device. In response, the requested user authentication information is transmitted to the authenticating entity, such that the user is automatically authenticated to the authenticating entity, without the user manually entering the requested user authentication information.

主权项

1. A computer implemented method for using a graphical authentication identifier to automatically authenticate a user, the method comprising the steps of:
registering a user operated computing device associated with a user with an authenticating entity for user authentication, using a unique device identifier; generating a onetime use graphical authentication identifier to be displayed by the authenticating entity for a first site of a plurality of sites, by at least one computer; encoding a request for a first user authentication information that is specific to the first site by the authenticating entity in the onetime use graphical authentication identifier, by the at least one computer, wherein the first user authentication information requested by the first site differs from a second user authentication information requested by a second site of the plurality of sites; and responsive to the registered user operated computing device associated with the user capturing the onetime use graphical authentication identifier being displayed by the authenticating entity, receiving a transmission of requested user authentication information to the authenticating entity, by the at least one computer, such that the user associated with the registered user operated computing device is automatically authenticated to the authenticating entity, without the user manually entering the requested user authentication information.
