About The Accountability Platform

In response to increased awareness and demand from consumers for more transparency and control over their personal data, there has been a proliferation of new privacy regulations around the world that impact the way all businesses, including advertising businesses and marketers, can use consumer data, with risks of penalties and fines for non-compliance. As a result, standard technical frameworks such as the Transparency & Consent Framework (TCF) and the Global Privacy Platform (GPP), have been developed for businesses to provide consumers with transparency and controls over how their personal data is used.

The Accountability Platform is a specification for open, auditable data structures and standard practices to detect miscommunications and demonstrate, via standard data structures and reporting, accurate communications across the digital advertising supply chain of data use preference and restriction signals set by users and the digital properties they visit.

The Accountability Platform specification has been developed by the Rearc Accountability Working Group.
