Abstract

A mobile computing device is authenticated to a user using an NFC tag embedded within or attached to an object that is commonly carried or worn by the user. The NFC tag may be initially associated when an NFC reader of the device senses the NFC tag and wirelessly retrieves a tag identifier from the tag. The tag identifier is stored for subsequent retrieval. The authentication process begins by positioning the device proximate the object such that the NFC reader of the device retrieves the tag identifier from the NFC tag. In the event that the retrieved tag identifier matches the stored tag identifier, the mobile computing device is unlocked and the user may access the mobile computing device. If the retrieved tag identifier does not match the stored tag identifier, the user is not authenticated and the mobile computing device remains locked.

Claims

1. A computing device comprising:

a near field communication (NFC) reader configured to;

detect a first NFC tag external to the computing device, wherein the NFC tag is associated with a user, and

retrieve a first tag identifier from the first NFC tag; and

a processor configured to transmit the first tag identifier to a server in response to retrieving the first tag identifier, the server being coupled to a network that is accessible by the computing device, wherein receipt of the first tag identifier causes the server to store the first tag identifier for subsequent retrieval;

wherein the NFC reader is further configured to;

detect a second NFC tag external to the computing device, and

retrieve a second tag identifier from the second NFC tag; and

wherein the processor is further configured to;

retrieve the first tag identifier from the server in response to retrieving the second tag identifier from the second NFC tag,

determine whether the first tag identifier corresponds to the second tag identifier, and

in the event that the first tag identifier corresponds to the second tag identifier, transition the computing device from (i) a locked state preventing the user from accessing at least one primary function of the computing device to (ii) an unlocked state allowing the user to access the at least one primary function of the computing device.

2. The computing device of claim 1, wherein, in the event that the first tag identifier does not correspond to the second tag identifier, the computing device remains in the locked state where the processor is configured to prevent the user from accessing the at least one primary function of the computing device.

3. The computing device of claim 1, wherein the processor is configured to:

access a profile associated with the first tag identifier, and

configure the user-authenticated computing device based on the profile.

4. The computing device of claim 1, wherein the first NFC tag is associated with an object that is associated with the user.

5. The computing device of claim 4, wherein the object is a card.

6. The computing device of claim 4, wherein the object is a piece of jewelry.

7. The computing device of claim 1, wherein processor is further configured to temporarily store the first tag identifier in a memory of the computing device.

8. A system comprising:

a first object comprising a first near field communication (NFC) tag, the first NFC tag storing a first tag identifier, wherein the first object is associated with a user; and

a mobile computing device comprising;

a near field communication (NFC) reader configured to retrieve the first tag identifier from the first NFC tag; and

a processor configured transmit the first tag identifier to a server in response to retrieving the first tag identifier, the server being coupled to a network that is accessible by the mobile computing device, wherein receipt of the first tag identifier causes the server to store the first tag identifier for subsequent retrieval;

wherein the NFC reader is further configured to retrieve a second tag identifier from a second NFC tag; and

wherein the processor is further configured to;

retrieve the first tag identifier from the server in response to retrieving the second tag identifier from the second NFC tag,

determine whether the first tag identifier corresponds to the second tag identifier, and

in the event that the first tag identifier corresponds to the second tag identifier, transition the mobile computing device from (i) a locked state preventing the user from accessing at least one primary function of the mobile computing device to (ii) an unlocked state allowing the user to access the at least one primary function of the mobile computing device.

9. The system of claim 8, wherein, in the event that the first tag identifier does not correspond to the second tag identifier, the mobile computing device remains in the locked state where the processor is configured to prevent the user from accessing the at least one primary function of the mobile computing device.

10. The system of claim 8, wherein the processor is configured to:

access a profile associated with the first tag identifier, and

configure the user-authenticated mobile computing device based on the profile.

11. The system of claim 8, wherein processor is further configured to temporarily store the first tag identifier in a memory of the computing device.

12. A computer-implemented method comprising:

retrieving a first tag identifier from a first near field communication (NFC) tag;

associating the first tag identifier with a user by transmitting the first tag identifier to a server coupled to a network that is accessible by a computing device, wherein receipt of the first tag identifier causes the server to store the first tag identifier for subsequent retrieval, the first NFC tag being associated with an object that is associated with a user;

retrieving a second tag identifier from a second NFC tag;

in response to retrieving the second tag identifier, retrieving the first tag identifier from the server via the network;

determining whether the first tag identifier corresponds to the second tag identifier; and

in the event that the first tag identifier corresponds to the second tag identifier, transitioning the computing device from (i) a locked state preventing the user from accessing at least one primary function of the computing device to (ii) an unlocked state allowing the user to access the at least one primary function of the computing device.

13. The method of claim 12, wherein, in the event that the first tag identifier does not correspond to the second tag identifier, the computing device remains in the locked state thereby preventing the user from accessing the at least one primary function of the computing device.

14. The method of claim 12, further comprising:

accessing a profile associated with the second tag identifier, and

configuring the user-authenticated computing device based on the profile.

15. The method of claim 12, wherein the object is a card.

16. The method of claim 12, wherein the object is a piece of jewelry.

17. The method of claim 12, further comprising temporarily storing the first tag identifier at a memory of the computing device.
