Abstract

A personal digital key (e.g., which can be carried by a human) contains a memory having different service blocks. Each service block is accessible by a corresponding service block access key. As the personal digital key (PDK) moves around, it is detected by sensors. The sensors report position data, thus enabling location tracking of the PDK. The sensors also provide a data path to various applications. An application that has access to a service block access key can therefore access the corresponding service block on the PDK. The sensors themselves may also contain service block access keys.

Claims

1. A system comprising:

a personal digital key including a memory having a first service block and a second service block, the first service block accessible using a first service block access key and inaccessible without the first service block access key, the second service block accessible using a second service block access key and inaccessible without the second service block access key, wherein the first service block access keys is distinct from a credential received via input by a user, and wherein the first service block is shared by a plurality of applications authorized to access the first service block including a first application and a second application, wherein a first instance of the first service block access key is provided to the first application during a first registration and a second instance of the first service block access key is provided to the second application during a second registration, wherein providing instances of the first service application block access key is restricted to the plurality of applications authorized to access the first service block and the first service block access key is common across the instances and used by the plurality of applications to access the first service block.

2. The system of claim 1 further comprising:

the memory included in the personal digital key having a third service block accessible using a third service block access key, the third service block storing biometric information, the third service block access key used to access the biometric information to compare the biometric information to a biometric input; and

a biometric sensor for receiving the biometric input.

3. The system of claim 1 further comprising:

a biometric sensor for receiving a biometric input for comparison to biometric information stored in the first service block.

4. The system of claim 1 wherein one or more of the first service block and the second service block are accessible subsequent to a biometric authentication.

5. The system of claim 1 further comprising:

a first sensor and a second sensor at known locations, the first sensor capable of communicating with the personal digital key in a first microcell, the second key capable of communicating with the personal digital key in a second microcell; and

a sensor management module communicatively coupled to the first sensor and second sensor.

6. The system of claim 5 wherein the first sensor and second sensor are located inside a structure, and the sensor management module tracks location of the personal digital key within the structure.

7. The system of claim 5 wherein the sensor management module gathers position data from the first sensor and the second sensor and generates location tracking data based on the position data.

8. The system of claim 5 wherein the first sensor and second sensor are coordinated using a beacon.

9. The system of claim 1 wherein one or more of the first service block and the second service block include information used to complete a financial transaction.

10. A method comprising:

receiving, at a personal digital key including a memory, an instance of a first service block access key distinct from a credential received via input by a user;

determining a service block in the memory accessed using the received instance of the first service block access key, the memory including a first service block and a second service block, the first service block accessible using the first service block access key and inaccessible without the first service block access key, the second service block accessible using a second service block access key and inaccessible without the second service block access key, and wherein the first service block is shared by a plurality of applications authorized to access the first service block including a first application and a second application, wherein a first instance of the first service block access key is provided to the first application during a first registration and a second instance of the first service block access key is provided to the second application during a second registration, wherein distribution of instances of the first service application block access key is restricted to the plurality of applications authorized to access the first service block and the first service block access key is common across the instances and used by the plurality of applications to access the first service block; and

accessing the first service block in the memory using the received instance of the first service block access key.

11. The method of claim 10 wherein the first service block includes biometric information used for biometric authentication and the service block access key is received responsive to a biometric sensor receiving a biometric input.

12. The method of claim 11 wherein the biometric information is based on a fingerprint.

13. The method of claim 10 wherein the first service block includes information for completing a financial transaction.

14. The method of claim 13 wherein the information for completing the financial transaction is information associated with a credit card.

15. The method of claim 10 wherein the first service block includes log in information.

16. The method of claim 10 wherein the accessed service block is accessed subsequent to a biometric authentication.

17. The method of claim 10 wherein a sensor provides a data path between the accessed service block and an application.

18. The method of claim 10 wherein different applications can have access to different service block access keys and a sensor is capable of providing a data path between each application and the corresponding service block(s).
