Google is shifting the computational burden of federated learning from client devices to attested server-side Trusted Execution Environments (TEEs) for its Gboard keyboard. By publishing access policies to Sigstore's Rekor log and ensuring reproducible builds, this approach enables external verification of central differential privacy guarantees. This architectural change strengthens the trust model for on-device AI training by making privacy mechanisms auditable rather than opaque.
Google Research Moves Federated Learning Into TEEs: Gboard Now Trains With Externally Verifiable Differential Privacy
Google Research has unveiled a federated learning system that moves gradient computation from phones into attested server-side TEEs. Access policies are published to Sigstore's Rekor log and the binaries are reproducibly buildable, so central differential privacy can be checked externally. Gboard already uses it for English and Japanese next-word prediction.
