Abstract
In an anonymous matching system, a demand-side service platform (DSP) may select segments to populate a target audience. A data warehouse platform and a multichannel video programming distributor (MVPD) platform ingest address lists, eliminate personally identifiable information (PII) from the address lists, and process the de-identified addresses to generate deterministic unique anonymous household identifiers (UHIDs). Households may be selected, for example, at the DSP's direction, to form a query request without exposing the PII. In response to the query request, the MVPD platform determines a matching UHID and includes a matching household attribute, such as an IP address or the like, in a query response without exposing the PII.
