Each record of\nprocessing activity (ROPA) entry must capture the data categories, legal basis,\nretention periods, and data subjects involved.\n\n```python\nfrom agent import PrivacyImpactAssessmentEngine\n\nengine = PrivacyImpactAssessmentEngine()\n\n# Register a processing activity for assessment\nactivity = engine.register_processing_activity(\n    name=\"Customer Analytics Platform\",\n    description=\"Collects browsing behavior and purchase history for personalization\",\n    data_controller=\"Acme Corp\",\n    data_processor=\"CloudAnalytics Inc\",\n    data_categories=[\"browsing_history\", \"purchase_records\", \"ip_address\", \"device_id\"],\n    data_subjects=[\"customers\", \"website_visitors\"],\n    legal_basis=\"consent\",\n    retention_period_days=730,\n    cross_border_transfer=True,\n    transfer_destinations=[\"US\", \"IN\"],\n    automated_decision_making=True,\n)\nprint(f\"Registered activity: {activity['activity_id']}\")\n```\n\n### Phase 2: Data Flow Mapping\n\nMap all data flows from collection to deletion, identifying every touchpoint,\ntransformation, and storage location. This reveals hidden privacy risks in data\nmovement across systems.\n\n```python\n# Build the data flow map\nflow_map = engine.map_data_flows(\n    activity_id=activity[\"activity_id\"],\n    flows=[\n        {\n            \"stage\": \"collection\",\n            \"source\": \"Web browser cookie + form submission\",\n            \"destination\": \"CDN edge server\",\n            \"data_elements\": [\"ip_address\", \"device_id\", \"browsing_history\"],\n            \"encryption_in_transit\": True,\n            \"protocol\": \"TLS 1.3\",\n        },\n        {\n            \"stage\": \"processing\",\n            \"source\": \"CDN edge server\",\n            \"destination\": \"Analytics data warehouse (US-East)\",\n            \"data_elements\": [\"browsing_history\", \"purchase_records\", \"device_id\"],\n            \"encryption_in_transit\": True,\n            \"encryption_at_rest\": True,\n            \"protocol\": \"mTLS\",\n        },\n        {\n            \"stage\": \"storage\",\n            \"source\": \"Analytics data warehouse\",\n            \"destination\": \"S3 encrypted bucket\",\n            \"data_elements\": [\"browsing_history\", \"purchase_records\"],\n            \"encryption_at_rest\": True,\n            \"retention_days\": 730,\n            \"access_controls\": \"IAM role-based, MFA required\",\n        },\n        {\n            \"stage\": \"sharing\",\n            \"source\": \"Analytics data warehouse\",\n            \"destination\": \"Third-party ML provider (IN)\",\n            \"data_elements\": [\"browsing_history\", \"purchase_records\"],\n            \"encryption_in_transit\": True,\n            \"data_processing_agreement\": True,\n            \"cross_border\": True,\n        },\n        {\n            \"stage\": \"deletion\",\n            \"source\": \"S3 bucket + data warehouse\",\n            \"destination\": \"Secure erasure\",\n            \"method\": \"Cryptographic erasure + lifecycle policy\",\n            \"verification\": \"Automated deletion audit log\",\n        },\n    ],\n)\nengine.render_data_flow_diagram(flow_map)\n```\n\n### Phase 3: Privacy Risk Assessment with Scoring Matrix\n\nApply a structured risk scoring methodology evaluating likelihood and impact\nacross multiple privacy risk dimensions. The matrix aligns with both the\nNIST PRAM and ICO DPIA risk assessment approaches.\n\n```python\n# Run the risk assessment\nrisk_report = engine.assess_privacy_risks(\n    activity_id=activity[\"activity_id\"],\n    assessment_type=\"full_dpia\",\n)\n\n# Display risk matrix results\nfor risk in risk_report[\"risks\"]:\n    print(f\"[{risk['severity']}] {risk['category']}: {risk['description']}\")\n    print(f\"  Likelihood: {risk['likelihood']}/5 | Impact: {risk['impact']}/5 | Score: {risk['risk_score']}/25\")\n    print(f\"  Mitigation: {risk['recommended_mitigation']}\")\n```\n\nRisk categories evaluated include:\n1. **Data Minimization** -- Excessive collection beyond stated purpose\n2. **Purpose Limitation** -- Secondary use without legal basis\n3. **Cross-Border Transfer** -- Transfers without adequate safeguards (SCCs, BCRs)\n4. **Automated Decision Making** -- Profiling without human oversight or appeal\n5. **Data Subject Rights** -- Inability to fulfill access/erasure/portability requests\n6. **Third-Party Risk** -- Processor compliance gaps, subprocessor chains\n7. **Security Controls** -- Encryption, access control, breach response gaps\n8. **Retention** -- Storing data beyond necessity or legal requirement\n9. **Consent Management** -- Invalid or ambiguous consent mechanisms\n10. **Breach Notification** -- Inability to detect and notify within 72 hours (GDPR)\n\n### Phase 4: GDPR and CCPA/CPRA Alignment Checks\n\nRun automated compliance checks against specific regulatory requirements.\nThe engine maps each processing activity against article-level GDPR obligations\nand CCPA/CPRA consumer rights requirements.\n\n```python\n# GDPR compliance check\ngdpr_report = engine.check_gdpr_compliance(activity_id=activity[\"activity_id\"])\nprint(f\"GDPR Score: {gdpr_report['compliance_score']}/100\")\nfor finding in gdpr_report[\"findings\"]:\n    print(f\"  [{finding['status']}] Art.{finding['article']}: {finding['description']}\")\n\n# CCPA/CPRA compliance check\nccpa_report = engine.check_ccpa_compliance(activity_id=activity[\"activity_id\"])\nprint(f\"CCPA Score: {ccpa_report['compliance_score']}/100\")\nfor finding in ccpa_report[\"findings\"]:\n    print(f\"  [{finding['status']}] Sec.{finding['section']}: {finding['description']}\")\n```\n\n### Phase 5: Remediation Plan and Report Generation\n\nGenerate a prioritized remediation plan with specific action items, responsible\nparties, deadlines, and generate the formal PIA/DPIA report document.\n\n```python\n# Generate remediation plan\nremediation = engine.generate_remediation_plan(\n    activity_id=activity[\"activity_id\"],\n    risk_report=risk_report,\n    gdpr_report=gdpr_report,\n    ccpa_report=ccpa_report,\n)\n\nfor item in remediation[\"action_items\"]:\n    print(f\"[{item['priority']}] {item['action']}\")\n    print(f\"  Owner: {item['owner']} | Deadline: {item['deadline']}\")\n    print(f\"  Addresses: {', '.join(item['addresses_risks'])}\")\n\n# Generate formal DPIA report\nengine.generate_dpia_report(\n    activity_id=activity[\"activity_id\"],\n    output_path=\"dpia_report_customer_analytics.json\",\n    format=\"json\",\n)\nprint(\"[+] DPIA report generated\")\n```\n\n## Examples\n\n### Quick Screening Assessment\n\nDetermine whether a full DPIA is required using the ICO screening checklist:\n\n```python\nengine = PrivacyImpactAssessmentEngine()\n\nscreening = engine.run_screening_checklist(\n    uses_special_category_data=False,\n    large_scale_processing=True,\n    systematic_monitoring=True,\n    automated_decision_making=True,\n    cross_border_transfer=True,\n    vulnerable_data_subjects=False,\n    innovative_technology=True,\n    denial_of_service_or_rights=False,\n)\nprint(f\"DPIA Required: {screening['dpia_required']}\")\nprint(f\"Triggers: {screening['triggers']}\")\n# Output: DPIA Required: True\n# Triggers: ['large_scale_processing', 'systematic_monitoring',\n#            'automated_decision_making', 'cross_border_transfer',\n#            'innovative_technology']\n```\n\n### Batch Assessment of Multiple Processing Activities\n\n```python\nengine = PrivacyImpactAssessmentEngine()\n\nactivities = [\n    {\"name\": \"Email Marketing\", \"data_categories\": [\"email\", \"name\"],\n     \"legal_basis\": \"consent\", \"cross_border_transfer\": False},\n    {\"name\": \"HR Analytics\", \"data_categories\": [\"employee_id\", \"performance_scores\",\n     \"health_data\"], \"legal_basis\": \"legitimate_interest\", \"cross_border_transfer\": True},\n    {\"name\": \"Fraud Detection\", \"data_categories\": [\"transaction_data\", \"ip_address\",\n     \"device_fingerprint\"], \"legal_basis\": \"legitimate_interest\",\n     \"automated_decision_making\": True, \"cross_border_transfer\": False},\n]\n\nfor act_def in activities:\n    activity = engine.register_processing_activity(**act_def)\n    risk = engine.assess_privacy_risks(activity_id=activity[\"activity_id\"])\n    print(f\"{act_def['name']}: Overall Risk={risk['overall_risk_level']} \"\n          f\"({risk['risk_count_by_severity']})\")\n```\n\n### NIST Privacy Framework Profile Mapping\n\n```python\nengine = PrivacyImpactAssessmentEngine()\n\nprofile = engine.generate_nist_privacy_profile(\n    activity_id=activity[\"activity_id\"],\n    target_tier=\"tier_3\",  # Repeatable\n)\n\nfor function_id, outcomes in profile[\"functions\"].items():\n    print(f\"\\n{function_id}:\")\n    for outcome in outcomes:\n        status = \"PASS\" if outcome[\"implemented\"] else \"GAP\"\n        print(f\"  [{status}] {outcome['subcategory']}: {outcome['description']}\")\n```\n\n## Other files in
