Private Inference

Definition

Private inference is a cryptographic technique that allows a user to query a machine learning model without revealing their input data to the model owner, and conversely, without revealing the model parameters to the user. This method ensures confidentiality for both the query and the model during the prediction process. It utilizes advanced cryptographic primitives such as homomorphic encryption or secure multi-party computation. The objective is to enable secure, privacy-preserving use of AI services.
