GDPR Compliance Guide

This guide helps compliance officers configure Lucid to meet the requirements of the General Data Protection Regulation (GDPR) for AI systems processing personal data of EU residents.

Overview

The GDPR establishes comprehensive data protection requirements for organizations processing personal data of EU residents. When AI systems process personal data, they must comply with principles including lawfulness, purpose limitation, data minimization, accuracy, storage limitation, integrity/confidentiality, and accountability.

Lucid helps organizations meet these requirements through:

  • Automated PII detection via LLM Judge guardrails to identify personal data in AI inputs and outputs
  • Content safety and injection protection via LLM Judge Auditor
  • Programmable compliance guardrails via LLM Judge with framework-specific presets (GDPR template)
  • Comprehensive audit logging via AI Passports and TEE-signed evidence

Deploying for GDPR Compliance

Quick Start

Deploy an AI environment with the GDPR compliance profile:

lucid apply --model llama-3.1-8b --profile gdpr

This enables the following auditors: - LLM Judge Auditor - Injection protection, toxicity detection, secret exposure - LLM Judge - PII detection, bias guardrails, transparency checks (with GDPR template preset)

Custom Configuration

For more control, create a YAML configuration file:

# gdpr-environment.yaml
apiVersion: lucid.io/v1alpha1
kind: LucidEnvironment
metadata:
  name: gdpr-compliant-ai
spec:
  infrastructure:
    provider: gcp
    region: europe-west1  # EU region for data residency
  agents:
    - name: gdpr-agent
      model:
        id: meta-llama/Llama-3.1-8B
      gpu:

      auditorChain:
        preRequest:
          - auditorId: lucid-llm-judge-auditor
            name: Security Measures (Art. 32)
            env:
              INJECTION_BLOCK_ON_DETECTION: "true"
          - auditorId: lucid-llm-judge-auditor
            name: GDPR Guardrails (Art. 5, 22, 25)
        postResponse:
          - auditorId: lucid-llm-judge-auditor
            name: Output Safety & PII (Art. 5, 13)

Deploy with:

lucid apply -f gdpr-environment.yaml

Article-by-Article Guidance

Article 5: Principles Relating to Processing

Requirement: Personal data must be processed lawfully, fairly, transparently, and with purpose limitation, data minimization, accuracy, storage limitation, and integrity/confidentiality.

Lucid Implementation:

  1. LLM Judge - Detects personal data to support data minimization
  2. Automatically identifies PII in prompts and responses via built-in PII rails

  3. GDPR template preset provides purpose limitation and data minimisation guardrails

  4. AI Passports - Provide accountability records

  5. TEE-signed evidence of all processing activities
  6. Creates audit trail demonstrating compliance
env:
  PII_DETECTION_ENABLED: "true"
  PII_CATEGORIES: "name,email,phone,ssn,address,financial"

Article 13-14: Information to Data Subjects

Requirement: Data subjects must receive meaningful information about automated decision-making, including the logic involved.

Lucid Implementation:

  1. LLM Judge - Provides transparency guardrails
  2. GDPR template preset includes information provision checks
  3. Generates explanations for AI-assisted decisions

The AI Passport generated for each inference can serve as documentation of the processing logic applied.

Article 22: Automated Decision-Making

Requirement: Data subjects have the right not to be subject to decisions based solely on automated processing that significantly affect them, with safeguards including human intervention.

Lucid Implementation:

  1. LLM Judge - Detects bias and supports human oversight
  2. GDPR template preset includes automated decision and profiling risk guardrails
  3. Provides transparency into model behavior
env:
  BIAS_DETECTION_ENABLED: "true"
  FAIRNESS_METRICS: "demographic_parity,equalized_odds"
  FLAG_HIGH_IMPACT_DECISIONS: "true"

Article 25: Data Protection by Design

Requirement: Implement appropriate technical measures to ensure data protection principles are embedded in processing.

Lucid Implementation:

  1. LLM Judge - Built-in PII protection via guardrails
  2. LLM Judge Auditor - Security by design against prompt attacks
  3. All auditors execute in hardware-secured enclaves (TEEs), providing technical protection by design

Article 30: Records of Processing Activities

Requirement: Maintain records of processing activities including purposes, data categories, recipients, and security measures.

Lucid Implementation:

  1. AI Passports - Comprehensive processing records
  2. TEE-signed evidence of all AI system activities
  3. Records include timestamps, user identifiers (pseudonymized), and processing outcomes
# Export processing records for compliance documentation
lucid passport export --from 2025-01-01 --to 2025-03-31 --format json > art30_records.json

Article 32: Security of Processing

Requirement: Implement appropriate technical measures to ensure security appropriate to the risk.

Lucid Implementation:

  2. Adversarial testing identifies potential risks
  3. Custom LLM guards document model vulnerabilities

The evaluation results from the LLM Judge can be incorporated into your DPIA documentation.

Articles 44-49: International Data Transfers

Requirement: Personal data transfers outside the EU/EEA must have appropriate safeguards.

Lucid Implementation:

Evidence for Compliance Assessments

Demonstrating Compliance to Supervisory Authorities

Lucid provides verifiable evidence for GDPR compliance:

  1. AI Passports - Cryptographic certificates for each inference showing:
  2. Which auditors were applied
  3. What controls were enforced

  4. Hardware attestation proving secure execution

  5. Audit Logs - Comprehensive records of all processing activities

  6. Policy Documentation - Machine-readable policies that map to GDPR articles

# Generate compliance report
lucid passport list --from 2025-01-01 --to 2025-03-31

# View specific passport details
lucid passport show <passport-id>

# Export for supervisory authority review
lucid passport export --format pdf --compliance-report gdpr

For Your Data Protection Officer

The DPO can use Lucid's outputs to:

  1. Document processing activities (Art. 30) using AI Passport evidence
  2. Demonstrate security measures (Art. 32) via AI Passports
  3. Support DPIA documentation (Art. 35) with LLM Judge evaluation results
  4. Verify data residency (Art. 44-49) through TEE hardware attestations

Best Practices

  1. Enable all recommended auditors - The GDPR profile provides comprehensive coverage
  2. Configure PII redaction - Automatically remove unnecessary personal data
  3. Use EU regions - Deploy in europe-west1, europe-west4, or similar EU regions
  4. Retain logs appropriately - Configure retention periods per your legal requirements
  5. Review AI Passports regularly - Monitor for any compliance issues
  6. Document your configuration - Keep your YAML files as part of your compliance documentation
