Google introduces privacy analytics with zero-trust aggregation
Private analytics via zero-trust aggregation
What happened
Google has introduced zero-trust aggregation for its privacy analytics service, combining a new cryptographic aggregation method with hardware-protected TEEs. It can receive device data in a single message without multi-round online interaction. Google receives only anonymous, aggregate insights about groups; raw data is neither exposed nor reconstructible, even within the hardware-protected environment. TEE attestation provides participants with proof that the protocol ran as intended.
