Noise Injection

Definition ∞ Noise Injection is a technique where controlled, random data is added to a dataset or signal. In privacy-enhancing technologies, this process obscures individual data points, making it harder to identify specific users or transactions. The purpose is to protect sensitive information while still allowing for aggregate analysis or statistical inferences without compromising overall data utility.
Context ∞ Noise Injection is a relevant concept in discussions around data privacy and compliance within digital asset systems, particularly concerning zero-knowledge proofs and confidential transactions. News often covers methods for anonymizing blockchain data to meet regulatory requirements or user demands for privacy. Researchers are continuously working to balance the effectiveness of privacy preservation with the integrity and auditability of decentralized ledgers.
