Identifying Consuming Entity Behavior Across Domains

The present disclosure relates to identifying consuming entity behavior across domains. Identity records are stored in a memory accessible to a computing system. Each of the identity records comprises at least one attribute, and the identity records originate from a plurality of domains. A determination is made as to whether a first one of the identity records identifies a consumption entity that is identified by a second one of the identity records. The first and the second identity records originate from separate ones of the domains, and the second one of the identity records is associated with a persistent key. The persistent key is associated with the consumption entity. The first identity record is associated with the persistent key if the first identity record is determined to identify the consumption entity.
