Abstract
In accordance with a first aspect of the present disclosure, an enrollment device is provided, comprising: a token interface unit configured to couple the enrollment device to an external user authentication token; a user interface unit configured to provide visual information to a user through a plurality of optical output elements, said visual information being indicative of a progress of a biometric template enrollment in the authentication token; a user interface control unit configured to receive input data indicative of said progress from the authentication token through the token interface unit and to control the user interface unit using said input data.
Claims19
An enrollment device, comprising:
- a processor;
- and
- a memory storing a computer program executable by a processor, the computer program comprising:
- token interface instructions, when executed by the processor, couple the enrollment device to an external user authentication token, wherein the user authentication token includes a fingerprint sensor;
- user interface instructions, when executed by the processor, provide visual information to a user through a plurality of optical output elements, said visual information being indicative of a progress of a fingerprint template enrollment in the authentication token;
- and
- user interface control instructions, when executed by the processor, receive input data indicative of said progress from the authentication token through the token interface instructions and to control the user interface instructions using said input data,
- wherein the enrollment device is configured to transmit control commands to the user authentication token using the token interface instructions, to process response information received from the user authentication token through the token interface instructions, and to provide corresponding user feedback through the user interface instructions, wherein the user authentication token is configured to detect a finger touching the fingerprint sensor and to detect the finger lifting from the fingerprint sensor, and in response to the finger touch, an optical output element of the plurality of optical elements is activated to provide a positive feedback indication, and in response to a fingerprint being acquired from the finger, the optical output element is deactivated indicating that the fingerprint has been acquired and the finger may be lifted from the fingerprint sensor, thereby allowing the user of the user authentication token to control timing of fingerprint acquisition.

A method of facilitating enrollment of a biometric template, the method comprising:
- coupling the enrollment device to an external user authentication token through a token interface unit, wherein the user authentication token includes a fingerprint sensor;
- providing visual information to a user through a plurality of optical output elements comprised in a user interface unit of the enrollment device, said visual information being indicative of a progress of a fingerprint biometric template enrollment in the authentication token;
- and
- receiving, by a user interface control unit of the enrollment device, input data indicative of said progress from the authentication token through the token interface unit and controlling the user interface unit using said input data,
- wherein the enrollment device transmits control commands to the user authentication token through the token interface unit, processes response information received from the user authentication token through the token interface unit, and provides corresponding user feedback through the user interface unit, wherein the user authentication token is configured to detect a finger touching the fingerprint sensor and to detect the finger lifting from the fingerprint sensor, and in response to the finger touch, an optical output element of the plurality of optical elements is activated to provide a positive feedback indication, and in response to a fingerprint being acquired from the finger, the optical output element is deactivated indicating that the fingerprint has been acquired and the finger may be lifted from the fingerprint sensor, thereby allowing the user of the user authentication token to control timing of fingerprint acquisition.
