Abstract
In one embodiment of the invention, service providers generate bloom filters with the user ID codes of registered users and exchange the bloom filters with one another. In response to a request to locate a first user, a first service provider will query its own registration database to determine if the first user is registered with the first service provider. If the first user is not registered with the first service provider, then the first service provider will query its bloom filters to identify other service providers with which the first user may be registered. A positive response from a bloom filter indicates that the first user may or may not be registered with the service provider associated with that bloom filter, and a negative response indicates with certainty that the first user is not registered with the service provider associated with that bloom filter.
