In order to help increase transparency around ID solution usage as the advertising ecosystem readies itself for a post-cookie world, IAB Tech Lab, the digital advertising technical standards-setting body, today released id-sources.json. The standard was available for public comment until yesterday, October 12th 2021.
“As companies turn to different identity solutions that will replace the role of the third-party cookie, it’s important we continue to push for a transparent supply chain,” said Caitlin Fitzharris, Senior Product Manager, Index Exchange. “Knowing which identifier is used by whom helps all parties, and id-sources.json is an important step towards building auditable data structures to ensure consumer privacy.”
id-sources.json aims to: 1) Provide a standard way for companies to declare which user identity sources they use; 2)work like the other IAB Tech Lab supply chain transparency standards (e.g. sellers.json and buyers.json). It is a participant hosted, structured declaration that machines can read; 3)ease ad campaign execution between advertisers, publishers, and their chosen technology providers by making it clear who supports what .
Today it is not readily clear which companies are adopting the various new user ID solutions, and in the view of Alex Cone, Vice President, Privacy & Data Protection, IAB Tech Lab: “It’s critical that companies integrating with user identity sources do so in the open if they hope for this rapidly growing infrastructure to be sustainable in the face of privacy-driven changes.”…“We believe this is a foundational step toward accountability solutions that enable new forms of addressability to thrive in a post-third party cookie world and is in line with IAB Tech Lab’s commitment to improve industry transparency.”
