Abstract

Claims (28)

1. A method comprising:

scanning a fingerprint when a user interacts with a button;

making available one or more keys for a challenge-response to validate the user with a cloud service by powering a radio for a predetermined duration in response to the validated user interacting with the button; and

displaying a battery level in response to a second interaction with the button, wherein the button is part of a wearable personal digital device.

2. The method of claim 1 , wherein the one or more keys are part of a digital identifier which is part of a crypto/cipher engine.

3. The method of claim 2 , wherein the crypto/cipher engine is user-removable from the wearable personal digital device.

4. The method of claim 2 , wherein the crypto/cipher engine comprises a smartcard controller.

5. The method of claim 2 , wherein the crypto/cipher engine resides on a subscriber identity module card.

6. The method of claim 1 , wherein the one or more keys comprise a symmetric key.

7. The method of claim 1 , wherein the one or more keys comprises an asymmetric key.

8. The method of claim 1 , wherein scanning the fingerprint comprises positioning a finger of the user on a fingerprint sensor which is positioned on a surface of the button.

9. The method of claim 1 further comprising modifying an electrical functionality of the wearable personal digital device by opening a connector of a housing coupled to the button.

10. The method of claim 1 , wherein the radio comprises a near-field radio.

11. The method of claim 10 , wherein the near-field radio comprises an ISO 14443 compatible radio.

12. The method of claim 10 , wherein the near-field radio comprises an ISO 18092 compatible radio.

13. The method of claim 1 , wherein the radio comprises a non-near-field radio.

14. The method of claim 13 , wherein the non-near-field radio comprises a Bluetooth radio.

15. The method of claim 1 , wherein the radio comprises a near-field radio and a non-near-field radio.

16. A non-transitory machine-readable storage medium having one or more machine-executable

instructions that when executed cause a processor to perform a method comprising:

scanning a fingerprint when a user interacts with a button;

validating the user with a cloud service by applying one or more keys for a challenge-response;

powering a radio for a predetermined duration in response to validating the user after the user interacts with the button; and

displaying a battery level in response to a second interaction with the button, wherein the button is part of a wearable personal digital device.

17. The non-transitory machine-readable storage medium of claim 16 , wherein the one or more keys are part of a digital identifier which is part of a crypto/cipher engine.

18. The non-transitory machine-readable storage medium of claim 17 , wherein the crypto/cipher engine is user-removable from the wearable personal digital device.

19. The non-transitory machine-readable storage medium of claim 17 , wherein the crypto/cipher engine comprises a smartcard controller.

20. The non-transitory machine-readable storage medium of claim 17 , wherein the crypto/cipher engine resides on a subscriber identity module card.
