Query Privacy

Definition ∞ Query privacy refers to the ability of a user to submit a data request to a database or system without revealing the content of their query to the data provider or other observers. This ensures that the user’s interests or specific information needs remain confidential. Achieving query privacy is a significant challenge in both centralized and decentralized data environments.
Context ∞ In crypto news, query privacy is a crucial concern for privacy-preserving blockchains, decentralized finance (DeFi) applications, and any system handling sensitive user data. Technologies like zero-knowledge proofs and private information retrieval are being developed to enable users to access information or execute transactions without disclosing their intentions. The pursuit of robust query privacy solutions aims to enhance user control over their data footprint.
