A Survey on Privacy-Preserving Machine Learning Inference
Year: 2025
Type: article
Abstract: This paper examines methods to secure machine learning inference (ML inference) so that sensitive data remains private and proprietary models are protected during remote processing. We review several approaches—from cryptographic techniques like homomorphic encryption (HE) and secure multi-party computation (MPC), to hardware solutions such as trusted execution environments (TEEs), and complementary methods including differential privacy and split learning. Each method is analyzed in terms of security, efficiency, communication overhead, and scalability. Use cases in healthcare, finance, and education show how these techniques balance privacy with practical performance. We conclude by outlining open challenges and future directions for building robust, efficient privacy-preserving ML inference systems.
