Abstract

A method of linking a content object with a network resource presents a content object to a reader, discerns an identifier associated with the content object, transfers the identifier to an indexing system, and in response receives an internet address corresponding to the content object. To enhance the response of the indexing system, it includes multiple routers, which it selects based on location relative to the reader. For example, the method sends user location data to a master system, and in response, receives an address of an indexing system close to the user location.

Claims

1. In a content identification system, a method of routing comprising:

distributing portions of content identification registry among plural computers at different locations;

receiving a request to associate a content object with information about the content object, the request being based on information discerned from perceptual information of the content object; and

routing the request to a selected one of the plural computers based at least in part on location of the selected computer relative to a client from which the request is initiated.

2. The method of claim 1 wherein the routing is performed at least in part based on a content identification type provided with the request.

3. The method of claim 1 wherein the routing is performed in part on a requesting device based on content identification type selected from among plural content identification systems.

4. The method of claim 1 wherein load balancing is performed among the plural computers based on information about the content identification type and location of a request relative to one of the computers.

5. In a content identification system, a system of routing comprising:

a distributed network of computers at different locations, each comprising a portion of a content identification registry;

a router for receiving a request to associate a content object with information about the content object, the request being based on information discerned from perceptual information of the content object, and for routing the request to a selected one of the plural computers based at least in part on location of the selected computer relative to a client from which the request is initiated.
