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. An apparatus comprising:
a crypto/cipher engine having at least one digital identifier including one or more keys for a challenge-response;
a sensor to scan a feature of a user;
a radio; and
a processor circuitry coupled to the crypto/cipher engine, the sensor, and the radio, wherein the processor circuitry is to validate the user through the feature, 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 sensor.
2. The apparatus of claim 1 , wherein the processor circuitry is to display a battery level in response to the interaction with the sensor.
3. The apparatus of claim 1 comprising a connector that when opened modifies electrical functionality of the apparatus.
4. The apparatus of claim 1 , wherein the crypto/cipher engine comprises a smartcard controller.
5. The apparatus of claim 1 , wherein the crypto/cipher engine comprises a plurality of smartcard secure elements.
6. The apparatus of claim 1 , wherein the crypto/cipher engine is removable.
7. The apparatus of claim 1 comprises a subscriber identity module (SIM), wherein the crypto/cipher engine resides in or on the SIM.
8. The apparatus of claim 1 , wherein the radio comprises a near-field radio.
9. The apparatus of claim 8 , wherein the near-field radio comprises an ISO 18092 compatible radio or an ISO 14443 compatible radio.
10. The apparatus of claim 1 , wherein the radio comprises a non-near-field radio.
11. The apparatus of claim 10 , wherein the non-near-field radio comprises a Bluetooth radio.
12. The apparatus of claim 1 , wherein the one or more keys for the challenge-response comprises a symmetric key.
13. The apparatus of claim 1 , wherein the one or more keys for the challenge-response comprises an asymmetric key.
14. The apparatus of claim 1 , wherein the feature is a fingerprint of the user.
15. The apparatus of claim 1 comprises a button, wherein the sensor is on the button.
16. A method comprising:
scanning a feature of a user;
generating one or more keys for a challenge-response after scanning the feature of the user;
performing authentication, with a cloud services through a device, after generating the one or more keys; and
powering a radio for a predetermined duration based, at least in part, on an interaction of a validated user upon scanning the feature.
17. The method of claim 16 comprises displaying a battery level in response to scanning the feature.
18. The method of claim 16 , wherein the one or more keys for the challenge-response comprises a symmetric key.
19. The method of claim 16 , wherein the one or more keys for the challenge-response comprises an asymmetric key.
20. The method of claim 16 , wherein the radio comprises a near-field radio.
