Wearable personal digital identity card 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 wearable personal digital ID device comprising:
a crypto/cipher engine having at least one digital identifier including one or more keys for challenge-response;
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 the user through a fingerprint scan and to make the one or more keys for challenge-response 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; and
a housing formed to encircle the user's wrist, the housing comprising a connector that when opened modifies electrical functionality of the wearable personal digital identity device.
