DPIA Guidance
Data Protection Impact Assessment guidance for a2p implementations.
When Is a DPIA Required?
A DPIA is required when processing:
- Large-scale personal data
- Special categories (health, beliefs)
- Automated decision-making
- Systematic monitoring
Most a2p implementations involving memory storage should conduct a DPIA.
DPIA Template for a2p
1. Processing Description
| Item | Description |
| Purpose | User profile management for AI personalization |
| Data processed | Preferences, memories, interaction context |
| Data subjects | End users |
| Recipients | AI agents (with consent) |
| Retention | User-controlled |
2. Necessity Assessment
| Question | a2p Answer |
| Is processing necessary? | Yes - enables personalization |
| Could less data achieve goal? | Users control scope |
| Is legal basis clear? | Yes - consent/contract |
3. Risk Assessment
| Risk | Likelihood | Impact | Mitigation |
| Unauthorized access | Low | High | DID auth, signatures |
| Data breach | Low | High | Encryption, access logs |
| Profile inference | Medium | Medium | Scope restrictions |
| Purpose creep | Low | Medium | Purpose validation |
4. Mitigation Measures
| Measure | Implementation |
| Access control | Policy-based, scope filtering |
| Encryption | TLS 1.3, AES-256 at rest |
| Minimization | User-controlled scopes |
| Transparency | Consent receipts, audit logs |
| User control | Edit, delete, export capabilities |
Risk Scoring
Inherent Risk
Inherent Risk = Likelihood × Impact
| Score | Level | Action |
| 1-4 | Low | Monitor |
| 5-9 | Medium | Mitigate |
| 10-16 | High | Significant measures |
| 17-25 | Very High | Reconsider processing |
Residual Risk (After Mitigation)
| Risk | Inherent | After Mitigation |
| Unauthorized access | 12 (High) | 4 (Low) |
| Data breach | 12 (High) | 4 (Low) |
| Profile inference | 9 (Medium) | 3 (Low) |
Consultation
When to Consult DPA
- Residual risk remains high
- Novel technology
- Large scale processing
- Special categories without consent
a2p Recommendation
Most implementations using standard a2p patterns will have low residual risk and not require DPA consultation.
