Abstract

A system (20) is designed for identifying devices (1, 2, . . . ) which are arranged for detecting a sensory identifier and transmitting request messages comprising representations of the detected sensory identifier. The system comprises at least one correlation relation server (e.g. 5C) for correlating representations received from the devices (1, 2) so as to match two or more of those devices, preferably when the devices (1, 2) are in each other'"'"'s proximity. The system further comprises at least one proxy server (e.g. 8X) for routing a request message from a device (1, 2) to at least one correlation server (e.g. 5C), the routing being dependent on said representations or other information contained in the request messages.

Claims

1. A system for identifying devices arranged for detecting a sensory identifier and transmitting request messages containing representations of the detected sensory identifier, the system comprising at least one correlation server for correlating representations received from the devices so as to match two or more of those devices,

wherein at least one proxy server is configured to route a request message from a device to at least one correlation server, the routing being dependent on contents of the request messages.

2. The system according to claim 1, wherein each request message comprises a respective representation of the sensory identifier, and wherein each request message further contains at least one of

a client identification for identifying a device,

an application handle for identifying an application to be run by the device,

a handling policy indication for identifying a handling policy, and

a payload for conveying any additional information.

3. The system according to claim 2, wherein each request message further comprises a fingerprint which comprises a representation of environmental information, such as the temperature, at the location of the device which produced the respective representation of the sensory identifier.

4. The system according to claim 1, wherein the sensory identifier comprises at least one of a sound.

5. The system according to claim 1, further comprising a redirection server arranged for redirecting request messages back to the device while providing routing information.

6. The system according to claim 1, arranged for matching devices which are in each other'"'"'s proximity.

7. The system according to claim 1, wherein the devices are mobile device.

8. The system according to claim 1, further comprising at least one application server for carrying out an application involving matching devices.

9. The system according claim 8, wherein the at least one application server is arranged for communicating with the devices through a correlation server.

10. A proxy server for use in the system of claim 1.

11. A method of identifying devices arranged for detecting a sensory identifier and transmitting request messages containing representations of the detected sensory identifier, the method comprising.;

correlating representations received from the devices so as to match two or more of those devices; and

routing a request message from a device to at least one correlation server using at least one proxy server, the routing being dependent on contents of the request messages.

12. The method according to claim 11, wherein each request message comprises a respective representation of the sensory identifier, and wherein each request message further contains at least one of:

a client identification for identifying a device,

an application handle for identifying an application to be run by the device,

a handling policy indication for identifying a handling policy, and

a payload for conveying any additional information.

13. The method according to claim 12, wherein each request message further comprises a fingerprint which comprises a representation of environmental information, at the location of the device which produced the respective representation of the sensory identifier.

14. The method according to claim 11, wherein the sensory identifier comprises at least one of a sound.

15. A non-transitory computer readable medium storing computer executable instructions that, when executed, perform the method according to claim 11.
