DPWatch: A Framework for Hardware-Based Differential Privacy Guarantees
Bibliographic record
Abstract
Differential privacy (DP) and federated learning (FL) have emerged as important privacy-preserving approaches when using sensitive data to train machine learning models. FL ensures that raw sensitive data does not leave the users’ devices by training the model in a distributed manner. DP ensures that the model does not leak any information about an individual byclippingand addingnoiseto the gradients. However, real-life deployments of such algorithms assume that the third-party application implementing DP-based FL is trusted, and is thus given access to sensitive data on the data owner’s device/server. In this work, we propose DPWatch, a hardware-based framework for ML accelerators that enforces guarantees that a third party application cannot leak sensitive user data used for training and ensures that the gradients are appropriately noised before leaving the device. We evaluate DPWatch on two accelerators and demonstrate small area and performance overheads.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
