Tools

DPIA Threshold Checker

Evaluates whether a DPIA is required based on processing activity description. Checks Art. 35(3) mandatory triggers and 9 EDPB criteria.

# Check a processing activity (interactive prompts)
python scripts/dpia_threshold_checker.py --activity "AI-based credit scoring using financial and behavioral data of retail banking customers across EU"

# Check from JSON description
python scripts/dpia_threshold_checker.py --input processing.json

# JSON output
python scripts/dpia_threshold_checker.py --activity "Employee monitoring via CCTV in workplace" --json

# Generate blank input template
python scripts/dpia_threshold_checker.py --template > processing.json

Checks performed:

• Art. 35(3)(a): Automated decision-making with legal/significant effect
• Art. 35(3)(b): Large-scale processing of special category data (Art. 9) or criminal data (Art. 10)
• Art. 35(3)(c): Systematic monitoring of publicly accessible area on large scale
• 9 EDPB criteria from WP 248 rev.01 with two-criterion presumption rule

Output:

• Verdict: Required / Recommended / Not Required
• Art. 35(3) trigger matches
• EDPB criteria scores with reasoning
• Two-criterion presumption analysis

DPIA Risk Register

Manages a DPIA risk register in JSON format. Add risks, apply mitigations, and calculate residual risk.

# Initialize a new risk register
python scripts/dpia_risk_register.py init --output dpia_risks.json

# Add a risk
python scripts/dpia_risk_register.py add --register dpia_risks.json \
  --description "Unauthorized access to profiling data" \
  --rights-category "right-to-privacy" \
  --likelihood 4 --severity 3

# Add mitigation to a risk
python scripts/dpia_risk_register.py mitigate --register dpia_risks.json \
  --risk-id 1 --measure "Implement role-based access control" \
  --likelihood-reduction 2 --severity-reduction 1

# View risk register table
python scripts/dpia_risk_register.py view --register dpia_risks.json

# Generate residual risk summary
python scripts/dpia_risk_register.py summary --register dpia_risks.json --json

# Check Art. 36 consultation threshold
python scripts/dpia_risk_register.py art36-check --register dpia_risks.json

Reference Guides

EDPB Criteria

references/edpb_criteria.md

Complete EDPB 9-criteria assessment framework:

• Each criterion with description, indicators, and scoring guidance
• Art. 35(3) mandatory triggers
• Two-criterion presumption rule (WP 248 rev.01)
• Multi-jurisdictional DPIA analysis
• National blacklist/whitelist overview (DE, FR, IE, BE, NL, IT, PL)

Risk Scoring Methodology

references/risk_scoring_methodology.md

DPIA risk scoring from the data subject perspective:

• Likelihood and severity scales (1-5)
• Rights categories per Recital 75
• Risk level thresholds (Low/Medium/High/Very High)
• Mitigation effectiveness scoring
• Residual risk calculation
• Art. 36 consultation triggers
• Risk catalog: 20+ common DPIA risks

Workflows

Workflow 1: Full DPIA Assessment

Step 1: Threshold check — determine if DPIA required
        → python scripts/dpia_threshold_checker.py --activity "description"

Step 2: If Required or Recommended, describe the processing
        → Document purpose, legal basis, data categories, recipients, retention

Step 3: Assess necessity and proportionality
        → Confirm lawful basis (Art. 6, cumulative with Art. 9 if special categories)
        → Verify purpose limitation, data minimization, storage limitation

Step 4: Identify risks from data subject perspective
        → python scripts/dpia_risk_register.py init --output dpia_risks.json
        → Add risks using references/risk_scoring_methodology.md catalog

Step 5: Apply mitigations and calculate residual risk
        → python scripts/dpia_risk_register.py mitigate --register dpia_risks.json ...

Step 6: Check Art. 36 consultation requirement
        → python scripts/dpia_risk_register.py art36-check --register dpia_risks.json

Step 7: Document and review
        → python scripts/dpia_risk_register.py summary --register dpia_risks.json

Workflow 2: Quick Threshold Assessment

Step 1: Describe the processing activity
        → python scripts/dpia_threshold_checker.py --template > processing.json
        → Fill in processing details

Step 2: Run threshold check
        → python scripts/dpia_threshold_checker.py --input processing.json --json

Step 3: Review verdict and reasoning
        → Required: proceed to full DPIA (Workflow 1)
        → Recommended: proceed unless strong justification to skip (document)
        → Not Required: document the assessment and rationale

Workflow 3: AI System DPIA

Step 1: Classify AI system (EU AI Act risk level if applicable)
        → Map to DPIA triggers (automated decision-making, profiling, scoring)

Step 2: Run threshold check with AI-specific indicators
        → python scripts/dpia_threshold_checker.py --activity "AI system description"

Step 3: Dual-phase risk analysis (EDPB Opinion 28/2024)
        → Phase 1: Training data risks (collection, bias, consent)
        → Phase 2: Inference risks (decisions, profiling, transparency)

Step 4: Assess from data subject perspective
        → Add risks covering both training and inference phases
        → Include algorithmic bias, lack of transparency, unfair outcomes

Step 5: Apply mitigations specific to AI
        → Explainability measures, human oversight, bias testing
        → Document FRIA distinction per EU AI Act Art. 27 if applicable

Legal Precision Points

12 points of legal precision that distinguish expert-level DPIA work.

| # | Point | Detail | |---|-------|--------| | 1 | Art. 35(3) absolute triggers | Three mandatory triggers require DPIA regardless of other analysis: (a) automated decisions with legal effect, (b) large-scale special category/criminal data, (c) systematic public area monitoring | | 2 | Two-criterion presumption | If 2 or more of the 9 EDPB criteria are met, DPIA is presumptively required (WP 248 rev.01). Can rebut only with documented justification | | 3 | Art. 9 cumulative with Art. 6 | Special category data requires BOTH an Art. 6 lawful basis AND an Art. 9(2) exception. Neither alone is sufficient | | 4 | Large scale four-factor test | Assess: (a) number of data subjects, (b) volume of data, (c) geographic extent, (d) duration/permanence. No fixed numeric threshold | | 5 | National blacklists additive | SA-published lists of processing operations requiring DPIA add to (not replace) Art. 35(3) and EDPB criteria | | 6 | Multi-jurisdictional checking | If processing spans multiple member states, check each SA's blacklist. Most restrictive list applies | | 7 | Pre-processing obligation | DPIA must be completed BEFORE
