Wearable identity device for fingerprint bound access to a cloud service
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.
1. A key fob comprising:
a crypto/cipher engine having at least one digital identifier including one or more keys for a challenge-response;
a button accessible to a user of the key fob;
a fingerprint sensor positioned on a surface of the button to allow for fingerprint scanning when the user interacts with the button;
a radio; and
a processor circuitry coupled to the crypto/cipher engine, the button, the fingerprint sensor, and the radio, wherein the processor circuitry is to validate the user through a fingerprint scan, wherein the processor circuitry is to make the one or more keys for the challenge-response available to perform authentication with a cloud service through a device, and wherein the processor circuitry is to power the radio for a predetermined duration based on an interaction of a validated user with the button.
2. The key fob of claim 1 , wherein the processor circuitry is to display a battery level in response to a second interaction with the button.
3. The key fob of claim 1 comprising a connector that when opened modifies electrical functionality of the key fob.
4. The key fob of claim 1 , wherein the crypto/cipher engine comprises a smartcard controller.
5. The key fob of claim 1 , wherein the crypto/cipher engine comprises a plurality of smartcard secure elements.
6. The key fob of claim 1 , wherein the crypto/cipher engine is user-removable from the key fob.
7. The key fob of claim 1 , wherein the crypto/cipher engine resides on a subscriber identity module (SIM) card.
8. The key fob of claim 1 , wherein the radio comprises a near-field radio.
9. The key fob of claim 8 , wherein the near-field radio comprises an ISO 14443 compatible radio.
10. The key fob of claim 8 , wherein the near-field radio comprises an ISO 18092 compatible radio.
11. The key fob of claim 1 , wherein the radio comprises a non-near-field radio.
12. The key fob of claim 11 , wherein the non-near-field radio comprises a Bluetooth radio.
13. The key fob of claim 1 , wherein the radio comprises a near-field radio and a non-near-field radio.
14. The key fob of claim 1 , wherein the one or more keys for the challenge-response comprises a symmetric key.
15. The key fob of claim 1 , wherein the one or more keys for the challenge-response comprises an asymmetric key.
16. A key fob comprising:
a crypto/cipher engine having at least one digital identifier including one or more keys for a challenge-response;
a connector that when opened modifies electrical functionality of the key fob;
a button accessible to a user of the key fob;
a fingerprint sensor positioned on a surface of the button to allow for fingerprint scanning when the user interacts with the button;
a radio; and
a processor coupled to the crypto/cipher engine, the button, the fingerprint sensor, the radio, and the connector, wherein the processor is to validate the user through a fingerprint scan, wherein the processor is to make the one or more keys for the challenge-response available to perform authentication with a cloud service through a device, and wherein the processor is to power the radio for a predetermined duration based on an interaction of a validated user with the button.
17. The key fob of claim 16 , wherein the crypto/cipher engine comprises a smartcard controller.
18. The key fob of claim 16 , wherein the crypto/cipher engine comprises a plurality of smartcard secure elements.
19. The key fob of claim 16 , wherein the radio comprises a non-near-field radio.
20. The key fob of claim 19 , wherein the non-near-field radio comprises a Bluetooth radio.
