/02 About
Data and information protection engineering reference for data access revocation and residual-copy risk, including policy, logical interfaces, recovery and assurance.
Purpose: Data access revocation and residual-copy risk. Domain: Data and information protection. Family: decision. Scenario trigger: Revoke principal ability to use protected information. Input assurance: Active sessions, issued shares and data-derivative inventory. Evaluation: Identify controllable copies, offline grants and residual exposure. Governing policy: Data access revocation and downstream rights policy. Resource-side obligation: Terminate authorizations and propagate revocation to capable recipients. Protected concern: Distributed information usage and sharing ecosystem. Logical interface: Data object recipient lease grants revoke scope and residual copies. Evidence: Revocation scope ack state outstanding copies and residual risk. Failure: Offline plaintext copy or recipient ignoring rights revocation. Required recovery: Record non-revocable residual risk and invoke contractual response. Architectural invariant: Revoking central access does not erase previously exported plaintext Adoption: replace reference roles with concrete owner-controlled services. Specify exact provider/consumer identities, schema fields and classifications, signal provenance and freshness, idempotency, authorization lifetime, timeout/retry limits, observation and tamper evidence. A denied or failed operation must not silently become a permitted one. Scope: original vendor-neutral, implementation-agnostic technical reference model. Illustrative logical components and behaviors are neither a deployed system nor evidence of regulatory compliance. Package identities remain stable within the package; cross-package semantic reconciliation requires separate explicit registry support.
