Data Clean Room
Controlled data collaboration environment
A data clean room allows several parties to compare or analyze data under controls that limit access to individual records and sensitive outputs.
- When it applies
- It applies to advertising collaboration, measurement, or audiences when parties cannot directly exchange personal data without additional protection.
- What it is confused with
- It does not automatically anonymize all data or replace a lawful basis. Query and output design determine much of the risk.
- Architecture consequence
- Before connecting it, define purpose, join keys, output controls, retention, and responsibilities between participants.
