Proxy servers in device identification systems
First Claim
1. A system for identifying a combination of devices that are each arranged for detecting a sensory identifier and transmitting a request message containing a representation of the detected sensory identifier, the system comprisinga plurality of correlation servers, wherein the correlation servers are distinct from the devices, each correlation server being configured to correlate representations received in the request messages transmitted by different ones of the devices so as to match two or more of those different ones of the devices by determining whether the sensory identifier detected by the devices is the same,at least one proxy server for routing the request message from at least one of the devices to at least one selected correlation server, the at least one proxy server being configured to select the routing of each request message dependent on contents of the request message,wherein the at least one proxy server is distinct from the devices and wherein the at least one proxy server selects which of the plurality of correlation servers will correlate representations received from the devices so as to match two or more of those devices.

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.

5. A system for identifying a combination of devices that are each arranged for detecting a sensory identifier and transmitting a request message containing a representation of the detected sensory identifier, the system comprising
a plurality of correlation servers, wherein the correlation servers are distinct from the devices, each correlation server being configured to correlate representations received in the request messages transmitted by different ones of the devices so as to match two or more of those different ones of the devices by determining whether the sensory identifier detected by the devices is the same, a redirection server arranged for redirecting request messages back to the device while providing routing information for routing the request message from at least one of the devices to at least one selected correlation server, the redirection server being configured to select the routing of each request message dependent on contents of the request message.

10. A proxy server that is distinct from a combination of devices, wherein the proxy server in combination with a plurality of correlation servers provides a system for identifying the combination of devices,
wherein the devices are each arranged for detecting a sensory identifier and transmitting a request message containing a representation of the detected sensory identifier; -
wherein each of the plurality of correlation servers are distinct from the devices and are configured to correlate representations received in the request messages transmitted by different ones of the devices so as to match two or more of those different ones of the devices by determining whether the sensory identifier detected by the devices is the same; wherein the proxy server is distinct from the devices and configured for routing the request message from at least one of the devices to at least one selected correlation server, the proxy server configured to select, dependent on contents of the request message, which of the plurality of correlation servers will correlate representations received from the devices so as to match two or more of those devices, the proxy server.

11. A method of identifying a combination of devices that are each arranged for detecting a sensory identifier and transmitting a request message containing a representation of the detected sensory identifier, the method comprising:
-
using selectable ones of a plurality of correlation servers to correlate representations received in the request messages transmitted by the devices so as to match two or more different ones of those devices by determining whether the sensory identifier detected by the different ones of the devices is the same, the correlation servers being distinct from the devices; and routing the request message from at least one of the devices to at least one correlation server using at least one proxy server, the proxy server being configured to select the routing of each request message dependent on contents of the request message, and the at least one proxy server being distinct from the devices. - View Dependent Claims (12, 13, 14, 15)
