Built as an open-source, standalone solution with its own unique namespace, the UID2 framework enables deterministic identifiers and and offers user transparency and privacy controls.

There are two types of UID2 identifiers: raw UID2s and UID2 tokens. The UID2 identifier enables monetization of logged-in experiences from publisher websites, mobile apps, and CTV apps through programmatic workflows. Benefitting from several layers of security and privacy measures, UID2s are safely distributed across the open internet. UID2 is a non-proprietary standard, and is accessible to constituents across the advertising ecosystem including Advertisers, Publishers, DSPs, SSPs, SSOs, CDPs, CMPs, Identity Providers, Data Providers, and Measurement Providers.

This product creates a deployment of the UID2 Operator that generates and manages raw UID2s and UID2 tokens for UID2 participants. The product operates entirely within an AWS Nitro Enclave and manages UID2 token updates, including handling opt outs and encryption rotation.
