Abstract

A device includes a processor having a standby state, a control unit coupled to the processor to receive wireless identification information, and a storage device to store a processor wake policy. The control unit applies the policy to received wireless identification information to wake the processor.

Claims

1. A device comprising:

a processor having a standby state;

a storage device storing a processor wake policy;

a context module to provide an interface to a user of the device to allow the user of the device to define a criterion for waking the processor, the criterion part of the processor wake policy and including a location of the device; and

a control unit coupled to the processor and arranged to;

receive wireless identification information;

determine that the criterion for waking the processor in the processor wake policy is met by the received wireless identification information; and

wake the processor from the standby state to an active state responsive to determining that the criterion in the processor wake policy is met.

2. The device of claim 1 wherein the wireless identification information comprises RFID packets.

3. The device of claim 2 wherein the control unit validates encrypted and signed RFID packets.

4. The device of claim 1 wherein the control unit selectively discontinues receipt of wireless identification information.

5. The device of claim 1 and further comprising an RFID module having an antenna, circuitry, and a memory bank, the RFID module being coupled to the control unit to provide wireless identification information directly to the control unit, wherein the RFID module memory bank is not directly accessible to the processor.

6. The device of claim 5 wherein the wireless identification information comprises RFID packets that include a unique RF TAG ID, and wherein packets not having the unique RF TAG ID are rejected.

7. The device of claim 5 wherein the RFID module is directly coupled to the control unit via a secure connection.

8. The device of claim 1, wherein the interface is provided to the user of the device to define the processor wake policy to include criterion based on specific applications and types of applications.

9. The device of claim 1 and further comprising a cloud module to store the processor wake policy on remote storage.

10. The device of claim 9 wherein the cloud module encrypts the processor wake policy prior to storing the policy on remote storage.

11. A mobile device comprising:

a processor having a standby state;

a storage device storing a processor wake policy;

a touchscreen coupled to the processor;

an RFID module to receive an RFID packet;

a context module to execute on the processor and to provide an interface to a user of the device to allow the user of the device to define a criterion for waking the processor, the criterion part of the processor wake policy and including a location of the device; and

a control unit coupled to the processor and to the RFID module, the control unit arranged to;

determine that the criterion for waking the processor in the processor wake policy is met by information in the received RFID packet; and

wake the processor from the standby state to an active state responsive to determining that the criterion in the processor wake policy is met.

12. The device of claim 11 wherein the control unit validates encrypted and signed RFID packets.

13. The device of claim 12 wherein the control unit selectively discontinues receipt of wireless identification information upon receipt of a selected number of unauthorized RFID packets.

14. The device of claim 12 wherein only RFID packets that include a unique RF TAG ID are validated.

15. The device of claim 11, wherein the interface is provided to the user of the device to define the processor wake policy to include a criterion based on specific applications and types of applications.

16. The device of claim 12 and further comprising a cloud module to execute on the processor to store the processor wake policy on remote storage.

17. The device of claim 16 wherein the cloud module encrypts the policy prior to storing the processor wake policy on remote storage.

18. A method comprising:

using one or more computer processors;

providing an interface to a user to define a criterion for waking a processor of the one or more computer processors, the processor having a standby state, and the criterion part of a processor wake policy and including a location of the device;

receiving the processor wake policy;

responsive to receiving the processor wake policy, storing the processor wake policy in a memory;

receiving wireless identification information;

determining that the criterion for waking the processor in the processor wake policy is met by the received wireless identification information; and

waking the processor from the standby state to an active state responsive to determining that the criterion in the processor wake policy is met.

19. The method of claim 18 wherein the memory comprises processor secure storage that is not directly accessible to the processor.

20. A non-transitory computer readable medium having instructions for causing a device to perform a method, the method comprising:

providing an interface to a user to allow the user to define a criterion for waking a processor having a standby state, the criterion part of a processor wake policy and including a location of the device;

receiving the processor wake policy;

responsive to receiving the processor wake policy, storing the processor wake policy in a memory;

receiving wireless identification information;

determining that the criterion for waking the processor in the processor wake policy is met by the received wireless identification information; and

waking the processor from the standby state to an active state responsive to determining that the criterion in the processor wake policy is met.

21. The non-transitory computer readable medium of claim 20 wherein the memory comprises processor secure storage that is not directly accessible to the processor.
