Acoustic Exchange examines identifiers that are contained in event traffic and attempts to correlate their appearance across channels and across endpoints to build a contextual view of your customer.

Identifiers are attributes that can be used to identify a specific individual. When a Acoustic Exchange partner integrates its product with Acoustic Exchange, it declares which event and audience attributes that it intends to use as identifiers. Each identifier definition specifies a name, a value, and a type.

Acoustic Exchange partner products are free to assign any name to an identifier. The value is determined during the event. Acoustic Exchange uses the identifier type to correlate identifiers it finds in the event traffic. The identifier type must conform to one of the pre-defined types that Acoustic Exchange supports.

Acoustic Exchange monitors event traffic for the presence of these identifiers and attempts to correlate them across channels within a single Acoustic Exchange endpoint and across other endpoints in your Acoustic Exchange account. Acoustic Exchange does not compare identifiers between different user accounts. Acoustic Exchange stores identity records in an internal database that Acoustic Exchange refers to as the Identity Store.

Acoustic Exchange supports secure hashing of identifier information to avoid sharing sensitive personal information while still supporting identifier matching.
