Abstract

A personal digital ID device provides a digital identifier to a service for a predetermined duration in response to user interaction. The user interaction may include a button press. The personal digital ID device may be in the form of a bracelet, a key fob, or other form factor. The service may be provided by a mobile device, in the cloud, or elsewhere.

Claims

1. A personal digital ID device comprising:

a crypto/cipher engine having at least one digital identifier including one or more shared secret keys;

a button accessible to a user of the personal digital ID device;

a fingerprint sensor positioned on a surface of the button to allow for fingerprint scanning when the user interacts with the button;

a radio;

a processor coupled to the crypto/cipher engine, the button, the fingerprint sensor, and the radio, the processor configured to validate a user through a fingerprint scan and to make the one or more shared secret keys available to perform authentication with a cloud service through a mobile device by powering the radio for a predetermined duration in response to a validated user interacting with the button.

2. The personal digital ID device of claim 1 wherein the crypto/cipher engine comprises a smartcard controller.

3. The personal digital ID device of claim 1 wherein the crypto/cipher engine comprises a plurality of smartcard secure elements.

4. The personal digital ID device of claim 1 wherein the crypto/cipher engine is user-removable from the personal digital ID device.

5. The personal digital ID device of claim 4 wherein the crypto/cipher engine resides on a subscriber identity module (SIM) card.

6. The personal digital ID device of claim 1 wherein the radio comprises a near-field radio.

7. The personal digital ID device of claim 6 wherein the near-field radio comprises a ISO 14443 compatible radio.

8. The personal digital ID device of claim 6 wherein the near-field radio comprises a ISO 18092 compatible radio.

9. The personal digital ID device of claim 1 wherein the radio comprises a non-near-field radio.

10. The personal digital ID device of claim 9 wherein the non-near-field radio comprises a Bluetooth radio.

11. The personal digital ID device of claim 1 wherein the radio comprises a near-field radio and a non-near-field radio.

12. The personal digital ID device of claim 1 further comprising a flexible housing to allow the personal digital ID device to be worn as a personal accessory.

13. The personal digital ID device of claim 8 wherein the flexible housing includes a bracelet shape.

14. A bracelet comprising:

a housing formed to encircle a user'"'"'s wrist;

a crypto/cipher engine having at least one digital identifier including one or more shared secret keys;

a button accessible to a user of the personal digital ID device;

a fingerprint sensor positioned on a surface of the button to allow for fingerprint scanning when the user interacts with the button;

a radio;

a processor coupled to the crypto/cipher engine, the button, the fingerprint sensor, and the radio, the processor configured to validate a user through a fingerprint scan and to make the one or more shared secret keys available for a predetermined duration to perform authentication with a cloud service through a mobile device by powering the radio in response to a validated user interacting with the button.

15. The bracelet of claim 14 wherein the crypto/cipher engine comprises a smartcard secure element.

16. The bracelet of claim 14 wherein the radio comprises a near-field radio.

17. The bracelet of claim 14 wherein the radio comprises a non-near-field radio.
