Abstract

Embodiments of the invention are directed to systems and methods for maintaining coherency between different entities in a distributed system. A coherency module automatically detects a change in state in a first entity, wherein the change in state relates to a change in functional code in the first entity. A synchronization message is transmitted to a second entity to synchronize data in the second entity with data in the first entity as a result of the change in state. The second entity is configured to synchronize the data in the second entity with the data in the first entity after receiving the synchronization message.

Claims

1. A method for maintaining coherency, the method comprising:

automatically detecting by a processor, a change in state in a first entity, wherein the change in state relates to a change in functional code in the first entity; and

initiating a transmission of a synchronization message to a second entity to synchronize data in the second entity with data in the first entity;

wherein the second entity is configured to synchronize the data in the second entity with the data in the first entity after receiving the synchronization message.

2. The method of claim 1, wherein the first entity and the second entity are first and second devices, respectively.

3. The method of claim 1, wherein the second entity is configured to synchronize the data in the second entity with the data in the first entity based upon a predetermined policy.

4. The method of claim 1, wherein the change in state changes an internal software configuration in the first entity.

5. The method of claim 1, wherein initiating the transmission of the synchronization message to the second entity comprises transmitting the synchronization message from the first entity to the second entity.

6. The method of claim 1, wherein initiating the transmission of the synchronization message to the second entity comprises transmitting an initiation message to an intermediate entity, wherein the intermediate entity transmits the synchronization message to the second entity.

7. The method of claim 1, wherein the data in the first entity comprises payment account information.

8. The method of claim 1, wherein the first entity is a mobile device.

9. The method of claim 1, wherein the data in the second entity is associated with a state in the second entity.

10. The method of claim 1, wherein the change in state is associated with a role and a context.

11. A first entity comprising:

a processor;

a computer readable medium coupled to the processor, the computer readable medium comprising code executable by the processor to perform a method comprising;

automatically detecting a change in state in the first entity, wherein the change in state relates to a change in functional code in the first entity; and

initiating a transmission of a synchronization message to a second entity to synchronize data in the second entity with data in the first entity;

wherein the second entity is configured to synchronize the data in the second entity with the data in the first entity after receiving the synchronization message.

12. The first entity of claim 11, wherein the first entity and the second entity are first and second devices, respectively.

13. The first entity of claim 11, wherein the second entity is configured to synchronize the data in the second entity with the data in the first entity based upon a predetermined policy.

14. The first entity of claim 11, wherein the change in state changes an internal software configuration in the first entity.

15. The first entity of claim 11, wherein the data in the second entity is associated with a state in the second entity.

16. The first entity of claim 11, wherein initiating the transmission of the synchronization message to the second entity comprises transmitting an initiation message to an intermediate entity, wherein the intermediate entity transmits the synchronization message to the second entity.

17. The first entity of claim 11, wherein the data in the first entity comprises payment account information.

18. The first entity of claim 11, wherein the first entity is a mobile device.

19. A system comprising:

a first entity; and

a second entity, wherein the first and second entities are communicatively coupled to each other; and

wherein the first entity comprises;

a processor;

a computer readable medium coupled to the processor, the computer readable medium comprising code executable by the processor to perform a method comprising;

automatically detecting a change in state in the first entity, wherein the change in state relates to a change in functional code in the first entity; and

initiating, by the first entity, a transmission of a synchronization message to the second entity to synchronize data in the second entity with data in the first entity;

wherein the second entity is configured to synchronize the data in the second entity with the data in the first entity after receiving the synchronization message.

20. The system of claim 19, wherein the first entity is a mobile device and the second entity is a wallet provider.
