Tech Lab releases ADMaP supporting privacy-centric attribution

IAB Tech Lab, the global digital advertising technical standards-setting body, announced today the launch of ADMaP (Attribution Data Matching Protocol) for public comment. Built by privacy, measurement and data clean room experts, ADMaP enables advertisers and publishers to securely share and measure conversion data without revealing user-specific details. The protocol leverages Privacy Enhancing Technologies (PETs) like Private Set Intersection(PSI) and Trusted Execution Environments(TEEs)  to ensure privacy and data security.

The ADMaP protocol uses several privacy-centric steps – identity mapping, attribution computation, and report generation. These steps utilize Privacy Enhancing Technologies like  secure multiparty computation cryptography and Trusted Execution Environments (TEEs) to ensure secure, encrypted, private data handling, enabling publishers to share exposure data and advertisers to share conversion data without the risk of revealing user-specific information. The protocol also empowers data clean rooms to provide cryptographically guaranteed features that maintain the integrity and privacy of their client’s data.

“The shift away from traditional identifiers and associated techniques used for attribution has created an urgent need for new, privacy-forward solutions. Signal loss limits advertisers’ ability to measure campaigns accurately  and ultimately impacts publishers revenues,” said Anthony Katsur, CEO, IAB Tech Lab. “ADMaP is a game-changer, enabling advertisers and publishers to collaborate safely, and accurately determine measurement and attribution, while fully protecting their audience’s privacy. This isn’t just about compliance – it’s about building trust and setting a new standard for how data can be shared responsibly in our industry for specific purposes.”
