AI Standard: Privacy, Data Protection, and the Right to Non-Inference

Define enforceable privacy and data protection requirements for AI systems, with particular emphasis on harms arising from inference rather than from data collection alone.

This standard treats inference as a governed action: it can create sensitive information, enable discrimination, and undermine autonomy even when no “sensitive data” was directly collected.

  • A2 Human Dignity & Moral Agency: protects autonomy and meaningful consent; prevents covert profiling
  • A3 Justice, Due Process, and Remedy: enables contestation, accountability, and corrective action
  • A4 Truthfulness & Trustworthiness: requires accurate disclosures and auditable evidence
  • A5 Proportionality & Moderation: constrains inference by risk tier and purpose
  • A7 Stewardship (Societal & Environmental): limits systemic privacy harm and long-horizon confidentiality risk

This standard applies to AI systems that:

  • process personal data (directly or via linkage), or
  • produce, store, or act upon inferences about identifiable individuals, or
  • materially influence decisions affecting individuals or groups in ways that create privacy externalities (e.g., profiling, ranking, eligibility, surveillance).

This standard is globally portable and avoids jurisdiction-specific legal mandates. It is compatible with common privacy principles (minimization, purpose limitation, access control, transparency, and accountability).

These definitions supplement 00_foundations/definitions.md.

  • Inference: deriving information, predictions, classifications, embeddings, or scores about a person (or a person-linked group) from input data, model behavior, metadata, or correlated signals, including inferences produced indirectly (e.g., via downstream models or data brokers).
  • Inference activity: any operation that generates, updates, stores, shares, or uses an inference to influence a decision, ranking, or action.
  • Sensitive inference: an inference that reveals or strongly suggests a sensitive attribute, condition, or status that could reasonably lead to stigma, discrimination, coercion, or significant harm if misused or disclosed.
  • Sensitive attributes (non-exhaustive): health conditions; mental health status; disability; genetic traits; biometrics used for identification; sexual behavior/orientation; intimate relationships; political views/affiliation; religious or philosophical beliefs; union membership; immigration or citizenship status; precise location and movement patterns; criminal allegations or records where misuse is plausible; financial distress; minor status; experiences of violence or abuse.
  • Purpose binding: restricting inference activity to explicitly declared purposes and prohibiting repurposing without a new justification and valid consent or lawful basis.
  • Unauthorized inference: inference activity that is outside declared purpose, outside granted permissions, or violates prohibitions in this standard.

AI-PN-1 (Privacy Principles). For Tier 1–3 deployments, operators MUST implement and document:

  • data minimization (collect and process only what is necessary),
  • purpose limitation (use only for declared purposes),
  • storage limitation (retain only as long as necessary),
  • access controls (least privilege and segregation of duties),
  • auditability (logs sufficient for reconstruction and accountability).

AI-PN-2 (Inference as Governed Action). Operators MUST treat inference activity as a governed action by maintaining an inference register that includes:

  • inference categories performed (including derived scores/embeddings used for decisions),
  • declared purposes for each inference category,
  • risk classification for each inference category (see AI-PN-7),
  • authorized roles/systems, and
  • evidence artifacts and review cadence.

AI-PN-3 (Right to Non-Inference). Individuals MUST NOT be subject to sensitive inference unless:

  • the inference category is disclosed in an understandable form,
  • the purpose is declared and bound (AI-PN-4),
  • a valid consent or other documented lawful basis exists where required by context, and
  • risk-tier controls are met (AI-PN-7 to AI-PN-12).

AI-PN-4 (Purpose Binding for Inference). For Tier 1–3, operators MUST:

  • bind each inference category to declared purposes,
  • prohibit repurposing of inferences to materially different purposes without renewed review and consent/basis, and
  • ensure downstream consumers cannot use inferences outside scope (technical controls or contractual controls with audit rights).

AI-PN-5 (Inference-Specific Transparency). Where AI materially affects an individual, operators MUST provide transparency that includes:

  • whether inferences are used,
  • the types of inferences relevant to the context,
  • how to access meaningful explanation appropriate to the context, and
  • how to contest or seek correction (see AI-PN-10).

AI-PN-6 (Prohibited Sensitive Inference Categories). Operators MUST NOT perform, enable, or procure sensitive inference used for:

  • eligibility, access, or pricing decisions in high-impact contexts based on intimate or stigmatizing attributes without explicit, context-appropriate authorization and remedy protections, or
  • coercive targeting, exploitation, or discriminatory segmentation of vulnerable individuals or groups, or
  • deception or manipulation that undermines meaningful consent.

For Tier 2–3 systems, any sensitive inference for high-impact decisions MUST undergo explicit governance review and be justified as necessary and proportionate.

AI-PN-7 (Inference Risk Classification). Operators MUST classify inference categories into risk classes:

  • Class L (Low-risk): benign operational inferences with minimal harm potential (e.g., language preference for UI).
  • Class E (Elevated): inferences with moderate harm potential or plausible misuse (e.g., inferred interests used for personalization in non-high-impact settings).
  • Class H (High-risk): inferences that can materially affect rights, access, liberty, or safety, or that can reasonably enable discrimination, coercion, or surveillance.
  • Class P (Prohibited by default): inference categories that are inherently sensitive in context, lack proportional justification, or create unacceptable risk of irreversible harm.

Classification MUST be context-dependent and documented, including:

  • stakes and affected parties,
  • plausibility of misuse,
  • reversibility of harm,
  • available remedy mechanisms.

AI-PN-8 (Tier Controls for Inference Classes).

  • Tier 1: operators MUST maintain the inference register and apply purpose binding (AI-PN-2, AI-PN-4).
  • Tier 2–3: operators MUST implement monitoring and detection for unauthorized inference (AI-PN-11), and MUST maintain a residual inference risk register (AI-PN-12).
  • For Class H and any sensitive inference: Tier 2–3 operators MUST provide enhanced transparency (AI-PN-5) and contestability (AI-PN-10).
  • Class P inferences MUST NOT be deployed unless a governance exception is granted under Tier 3 review with documented public-interest justification and safeguards; otherwise they remain prohibited.

AI-PN-9 (No Reliance on “Anonymization” Alone). Operators MUST NOT rely solely on de-identification or anonymization claims to justify sensitive inference or secondary use. Where de-identification is used, operators MUST:

  • assess linkage and inference risks,
  • implement technical and organizational safeguards against re-identification and attribute inference, and
  • document residual risks.

AI-PN-10 (Subject Rights: Access, Correction, and Contestation). For Tier 2–3 systems that materially affect individuals, operators MUST provide a process to:

  • request an explanation appropriate to the context,
  • contest the use of relevant inferences in decisions,
  • seek correction of materially wrong inferences where feasible, or record a dispute when correction is not feasible,
  • obtain human review for high-impact decisions.

AI-PN-11 (Logging and Detectability of Inference Activity). Tier 2–3 operators MUST log inference activity sufficient to detect unauthorized inference and reconstruct:

  • which inference categories were generated/used,
  • the system/model version,
  • the consuming decision/workflow context (at an appropriate granularity),
  • access events and downstream sharing.

Operators MUST monitor for:

  • inference activity outside declared purposes,
  • anomalous inference generation rates,
  • unauthorized access to inference stores or embedding indices.

AI-PN-12 (Residual Inference Risk Register). Tier 2–3 operators MUST maintain a residual inference risk register that includes:

  • inference class (L/E/H/P) and justification,
  • primary harms and misuse pathways,
  • mitigations and residual risk,
  • monitoring thresholds and escalation triggers,
  • owners and review cadence.

AI-PN-13 (Secondary Use Governance). For Tier 2–3, any secondary use that materially changes the purpose or increases inference risk MUST:

  • be reviewed under the inference risk classification framework,
  • document necessity and proportionality,
  • include safeguards (minimization, access controls, retention limits, transparency/consent where required).

AI-PN-14 (Post-Quantum and Long-Horizon Confidentiality). When data or inferences have long confidentiality requirements, operators MUST:

  • document cryptographic assumptions and dependencies,
  • apply cryptographic agility planning appropriate to sensitivity and retention horizon,
  • limit retention of high-risk inferences and sensitive logs to the minimum necessary,
  • consider “harvest now, decrypt later” risk for stored sensitive data and inferences.

Where QC-related crypto destabilization is plausible, operators SHOULD align with 03_quantum_standards/cryptographic_and_security_risk.md.

AI-PN-15 (Inference-Minimizing Design). Operators SHOULD prefer designs that minimize sensitive inference creation, such as:

  • on-device processing or local personalization where feasible,
  • explicit feature constraints to exclude sensitive proxies,
  • privacy-preserving learning and aggregation when appropriate.

AI-PN-16 (Independent Review for High-Risk Inference). For Tier 3 systems and Class H/P inference categories, operators SHOULD obtain independent review of:

  • classification and justification,
  • monitoring and detection design,
  • contestability and remedy effectiveness.

AI-PN-17 (Public Transparency Summary). Tier 2–3 operators MAY publish a redacted inference transparency summary describing:

  • major inference categories,
  • purpose bindings,
  • prohibited inferences,
  • high-level monitoring and remedy mechanisms,

with redactions limited to privacy, safety, or legal constraints.

  • Tier 0: research systems should document inference categories and avoid releasing artifacts that enable sensitive inference at scale without safeguards.
  • Tier 1: requires explicit inference inventory and purpose binding; sensitive inference requires disclosure and governance justification.
  • Tier 2: requires logging, monitoring, residual risk tracking, and subject rights mechanisms appropriate to context.
  • Tier 3: requires strongest constraints, independent review expectations, and pause readiness (ESCALATION_AND_PAUSE.md) for Class P and other systemic-risk inference categories.

Minimum evidence artifacts (as applicable):

  • privacy principles implementation notes and policies (AI-PN-1)
  • inference register and purpose bindings (AI-PN-2, AI-PN-4)
  • disclosure/consent materials for inference categories (AI-PN-3, AI-PN-5)
  • prohibited inference policy and enforcement controls (AI-PN-6)
  • inference risk classification records (AI-PN-7)
  • logging schemas, access logs, and monitoring alerts (AI-PN-11)
  • residual inference risk register and remediation tracker (AI-PN-12)
  • secondary use governance decisions and safeguards (AI-PN-13)
  • cryptographic inventory and retention schedules for long-horizon data (AI-PN-14)

  • Sensitive inference can arise from proxies even when protected attributes are not collected; prohibitions and monitoring reduce but may not eliminate risk.
  • Some inferences are hard to “correct” because they are probabilistic or transient; dispute recording and decision review are still required in high-impact contexts.
  • Logging improves accountability but can itself create privacy risk; retention and access controls must be strict and proportional.
  • Standardized machine-readable inference registers to support procurement and audit interoperability.
  • Privacy-preserving monitoring techniques for detecting unauthorized inference without expanding surveillance.
  • Better benchmarks for inference attack resistance (membership/attribute inference) in deployed settings.

Privacy harms increasingly arise from what systems infer and how those inferences are used, shared, and operationalized. Treating inference as a governed action—bound by purpose, transparency, and auditable controls—closes a major gap in traditional privacy models centered only on collection and disclosure.
