Stimulus/response-based binding of identifiers across information domains while maintaining confidentiality

摘要

Disclosed are methods for extracting and using information about an entity that has a presence in a number of information domains. The entity has separate identifiers in each of several domains. Various techniques are described that bind together the identifiers of the entity across the domains. The results of the binding are provided to an interested party that can review information extracted about the entity's behavior in the multiple domains. The interested party is not given access to information that would compromise the confidentiality of the entity. A trusted broker has access to information about the behavior of the entity in the several domains. The broker analyzes that information and provides the analysis to the interested party, again without compromising the confidentiality of the entity. An “incentivizer” works with the broker to extract from the domains information that would be useful in binding together the different identifiers of the entity.

1. A method for binding an entity's identifiers in a multi-domain environment, the method comprising:
providing a first presence identifier in a first domain and a second presence identifier in a second domain of the entity, providing a binder server under processor control to bind together the first and second presence identifiers, at the binder server having a binding process for: sending a stimulus in association with the first presence identifier; receiving, by the binding process, information associated with a response to the stimulus, the response associated with the second presence identifier, the first domain being distinct from the second domain; analyzing, by the binding process, the stimulus and the received response information to associate the first presence identifier with the second presence identifier; creating, by the binding process, a cross-domain identifier that logically binds together the first and second presence identifiers, the cross-domain identifier providing access to some non-identity information associated with the first presence identifier, the cross-domain identifier providing access to some non-identity information associated with the second presence identifier; and providing, by the binding process, the cross-domain identifier to a process distinct from the binding process.
