Privacy-Preserving ML Framework Using Homomorphic Encryption

ai-technology · 2026-04-29

A new framework enables training machine learning models on encrypted data without decryption, preserving privacy throughout the pipeline. The proof-of-concept uses Cheon-Kim-Kim-Song (CKKS) for approximate real-number arithmetic and demonstrates feasibility on K-Nearest Neighbors (KNN) and linear regression models, with encrypted inference for a basic Multilayer Perceptron (MLP) architecture. Published on arXiv (2604.23245), the work addresses privacy challenges in data-driven decision-making by allowing computations on encrypted data, preventing unauthorized access during processing.
