Definition ∞ Membership inference is a type of privacy attack where an adversary attempts to determine if a specific data record was included in the training dataset of a machine learning model. This attack can compromise the privacy of individuals whose data was used. It exploits vulnerabilities in how models learn and generalize from data. Such attacks pose a risk to systems that rely on sensitive user information.
Context ∞ Membership inference attacks pose a growing concern in areas where machine learning models are applied to sensitive digital asset data or user behavior analytics. The development of privacy-preserving machine learning techniques, such as differential privacy, aims to mitigate these risks. Researchers actively work on robust defenses to protect user privacy in AI-driven decentralized applications.
