Definition ∞ Machine learning privacy addresses the challenge of protecting sensitive data used in training and deploying machine learning models, particularly when dealing with personal or confidential information. It involves techniques to prevent the unauthorized extraction or inference of private data from models or their outputs. In the context of digital assets, this applies to analytical systems that process transaction data or user behavior on blockchains, aiming to preserve user anonymity.
Context ∞ The intersection of machine learning and blockchain technology presents both opportunities and significant privacy concerns. While machine learning can aid in fraud detection and market analysis for digital assets, ensuring that this analysis does not compromise user privacy is paramount. Researchers are actively exploring privacy-preserving machine learning methods, such as federated learning and homomorphic encryption, to address these challenges in decentralized environments.
