❓ Frequently Asked Questions
What is privacy-preserving analytics?
Analytics that extract insights from data without exposing individuals’ raw information, using techniques like local processing, data minimization, and privacy-preserving methods such as differential privacy or encryption.
What is federated learning?
A distributed machine learning approach where models are trained on users’ devices with local data, and only model updates are sent to a central server to create a global model—raw data never leaves the device.
How does federated learning protect privacy?
By keeping data on devices, sharing only model updates, and often using secure aggregation and differential privacy to prevent the server from learning about any individual’s data.
What techniques are commonly used in privacy-preserving analytics?
Differential privacy, secure aggregation/secure multi-party computation, encryption (e.g., homomorphic encryption), and on-device privacy-aware model training.
