    "purpose": "Enable an AI agent to assess a data anonymization activity, record the evidence supporting its claimed protection, and decide whether its outputs are suitable for a specified use and access setting.",
    "definition": "Data anonymization is the process of modifying or releasing data so that individuals cannot reasonably be identified from it, including through linkage with other available information, with adequacy depending on the disclosure context and assumed attacker capabilities.",
    "scope_statement": "This model owns the activity of transforming data and evaluating its outputs against an explicit anonymity criterion, including identification threats, utility requirements, release conditions, and reassessment triggers; it does not assume that removing identifiers establishes anonymity.",

      "Encryption protects data through restricted access to a decryption capability; an anonymization claim requires assessment of what recipients can infer from the accessible output.",
