Policy Privacy

Definition ∞ Policy privacy pertains to the confidentiality of the rules and conditions that govern a system’s operation or data access. It means that the specifics of a policy are concealed from unauthorized parties, even as the policy is being enforced or updated. This concept is distinct from data privacy, focusing instead on the secrecy of the control logic itself. It ensures that sensitive operational parameters remain undisclosed.
Context ∞ In decentralized systems, especially those employing zero-knowledge proofs, policy privacy is a growing area of interest. It allows for the verification of compliance with certain rules without revealing the rules themselves, which can be critical for proprietary business logic or national security applications. The challenge involves designing cryptographic mechanisms that permit verifiable policy enforcement while preserving the confidentiality of the policy content.
