Secure, remote biometric enrollment
Devices, systems, and methods facilitate enrollment of authenticating biometric data for authenticating an authorized user via a biometric sensor. A data input device and a power source are operatively coupled to a smart card including a fingerprint sensor. An activation code input by the user interacting with the data input device is compared with a predefined activation code, and if the detected activation code matches the predefined activation code, a fingerprint template is enrolled from fingerprint data received from the fingerprint sensor, all without transmitting data from either the power source or the data input device to any device other than the smart card.
1. A method for enrolling a fingerprint template on a smart card having a processor, a data storage element, and fingerprint sensor, the method comprising:
temporarily attaching a data input device to the smart card;
connecting the smart card to a power source;
detecting an activation code entered by a user interacting with the data input device;
comparing the detected activation code with a predefined activation code stored in the data storage element;
if the detected activation code matches the predefined activation code, enrolling a fingerprint template from fingerprint data received from the fingerprint sensor; and
after enrolling the fingerprint template, removing the smart card from the data input device and the power source,
wherein the detecting step, the comparing step, and the enrolling step are performed by the processor without transmitting data from either the power source or the data input device to any device other than the smart card.
2. The method of claim 1 , further comprising providing the predefined activation code to the user separately from the data input device.
3. The method of claim 2 , wherein providing the predefined activation code comprises transmitting the predefined activation code to the user by one of telephone, text message, and on-line download.
4. The method of claim 1 , wherein the fingerprint sensor comprises a two-dimensional array of sensor elements, and the data input device comprises two or more keys, each key being operatively associated with a different spatially-distinct data input region of the array.
5. The method of claim 1 , wherein the fingerprint sensor comprises a two-dimensional array of sensor elements, and the detecting step comprises detecting activation of different spatially distinct regions of the array of sensor elements via the user interacting with the data input device.
6. The method of claim 1 , further comprising enabling a user to enter the activation code into the fingerprint sensor by interacting with each of two or more distinct portions of the fingerprint sensor, wherein each of the two or more distinct portions of the fingerprint sensor corresponds to a uniquely-identifiable portion of the activation code.
7. A system comprising;
a smart card comprising a fingerprint sensor for authenticating a user of the smart card;
a data storage element integrated with the smart card and storing an activation code;
a data input device temporarily coupled to the smart card;
a power source coupled to the smart card; and
a processor integrated with the smart card and configured to translate a code input by a user interacting with the data input device and to compare the code input by the user with the stored activation code, and to enroll a fingerprint template from fingerprint data received from the fingerprint sensor if the detected activation code matches the stored activation code,
wherein neither the power source nor the data input device is able to transmit data to any device other than the smart card.
8. The system of claim 7 , wherein the data input device and the power source are disposed on a common support element.
9. The system of claim 8 , wherein the common support element comprises an overlay configured to be secured to a surface of the smart card.
10. The system of claim 8 , wherein the common support element comprise a sleeve, and wherein sleeve is configured to receive the smart card inserted therein.
11. The system of claim 7 , wherein the data input device is coupled to the fingerprint sensor.
12. The system of claim 11 , wherein the fingerprint sensor comprises a two-dimensional array of sensor elements, and the data input device comprises two or more keys, each key being operatively associated with a different spatially-distinct data input region of the array.
13. The system of claim 11 , wherein the fingerprint sensor comprises a two-dimensional array of sensor elements, and the data input device comprises an overlay placed over the array with two or more holes, each hole defining a data input key through which the user may contact a spatially distinct control area of the array.
14. The system of claim 7 , wherein the power source comprises a battery supported on a receptacle, and wherein the receptacle includes a slot configured to receive a portion of the smart card inserted therein to couple the smart card to the battery.
15. The system of claim 7 , further comprising a status indicator, wherein the status indicator provides an indication to the user regarding enrolment of the fingerprint template.
16. The system of claim 15 , wherein the status indicator is an LED, a screen, or a sound emitting unit.
