Abstract

A wearable device (4) for secure execution of Near Field Communications identity-based data transactions with an enclosure (8) that contains a secure NFC integrated circuit (40), a secure Bluetooth Low Energy integrated circuit (48), a microcontroller (48) with a firmware program (104), a battery (44), and a passive sensor (16) that activates the microcontroller (48) when the device is removed or donned by the user. If the NFC integrated circuit (40) is in the enabled state when the microcontroller (48) is activated by the sensor (16), the firmware program (104) disables the NFC integrated circuit (40) function. If the NFC integrated circuit (40) is the disabled state when the microcontroller (48) is activated by the sensor (16), the Bluetooth Low Energy integrated circuit (48) is activated and a Personal Identification Number must entered into a software application (112) running on a Bluetooth-connected computing device (22) to enable the NFC integrated circuit (40) function.

Claims

1. A device for providing identity authentication comprising:

an enclosure for providing attachment to the human body,

a passive sensor for sensing the donning of the device to the body and for sensing the removal of the device from the body,

a secure passive NFC communication sub-system configured to provide authentication of an identity associated with the device,

a secure wireless data communication sub-system for receiving identity confirmation data,

a battery for powering the wireless data communication sub-system and the NFC communication sub-system,

a software program for disabling a currently enabled NFC communication sub-system when the passive sensor is triggered, and for enabling a currently disabled NFC communication sub-system when the passive sensor is triggered and when identity confirmation data is received from an external device via the secure wireless data communication sub-system.

2. The device of claim 1 where the enclosure is in the form of a finger ring.

3. The device of claim 1 where the passive sensor is comprised of a fixed circuit contact and a slidable circuit contact.

4. The device of claim 1 where the enclosure includes a hinge member and a stretchable member.

5. The device of claim 1 where the enclosure is configured as a hollow substantially toroidal form with a partially circular NFC antenna concentric to the toroidal void inside of the enclosure.

6. The device of claim 1 where the currently disabled NFC communication sub-system is enabled if the identity confirmation data is received from the external device within 30 seconds of the passive sensor trigger.

7. The device of claim 1 where the interior space of the device is filled with an encapsulant.

8. A finger ring for providing identity authentication comprising:

a hollow substantially toroidal enclosure assembly comprising a top enclosure, a bottom enclosure, a hinge member, and a stretchable member;

a passive NFC processor for executing encrypted identity authentication and data transactions with an NFC base station,

a Bluetooth LE microprocessor for executing software instructions and for communicating with a computing device,

a battery,

an NFC antenna coil configured substantially concentric to and inside the toroidal enclosure, electrically connected to the NFC processor, and with a lobe shape that deflects to allow the bottom enclosure to rotate away from the top enclosure about the hinge member;

a rigid flex circuit board functionally connecting the passive NFC processor, the Bluetooth LE microprocessor, battery, an NFC antenna, and a Bluetooth antenna chip;

a passive sensor comprising a first contact fixedly attached to the top enclosure and connected to the positive voltage side of the battery, a second contact fixedly attached to the top enclosure and connected to a wake-up port on the Bluetooth processor, and a third contact fixedly attached to the bottom enclosure and protected by the stretchable member, that electrically connects the first contact and the second contact when one end of the bottom enclosure is displaced a specific distance from the corresponding end of the top enclosure, thereby waking the Bluetooth LE microprocessor;

a software application running on a computing device with an encrypted Bluetooth connection to the ring Bluetooth LE microprocessor for acquiring and validating a user'"'"'s personal identification number and sending an identity confirmation data message to the Bluetooth LE microprocessor, and

a software application running on the Bluetooth chip that disables a currently enabled NFC processor when the Bluetooth LE microprocessor is powered on, and enables a currently disabled NFC processor when the Bluetooth LE microprocessor is powered on and receives an identity confirmation data message from the computing device.

9. The device of claim 8 where the currently disabled NFC communication sub-system is enabled if the identity confirmation data message is received from the external device within 30 seconds of the passive sensor trigger.

10. The device of claim 8 where the internal voids in the top enclosure are substantially filled with encapsulant.
