Chiron: Privacy-preserving Machine Learning as a Service

Understand

Major cloud operators offer machine learning (ML) as a service, enabling customers who have the data but not ML expertise or infrastructure to train predictive models on this data.

• Existing ML-as-a-service platforms require users to reveal all training data to the service operator.
• We design, implement, and evaluate Chiron, a system for privacy-preserving machine learning as a service.
• First, Chiron conceals the training data from the service operator.
