Key Architectural Decisions

Decision 1: Integrated Privacy Stack (DP + SMPC + HE)

Rationale:

  • Differential privacy alone: 45% confidence, 5-10% accuracy loss
  • DP + SMPC: 75% confidence, 2-3% accuracy loss
  • DP + SMPC + HE: 85% confidence, <1% accuracy loss

Trade-off:

  • Complexity: High (3 cryptographic protocols)
  • Performance: 2-3x overhead
  • Value: Highest privacy guarantee + lowest accuracy loss

Decision 2: Blockchain Audit Trail (vs SQL Database)

Rationale:

  • SQL audit log: Mutable, vulnerable to tampering
  • Blockchain: Tamper-proof, cryptographically verifiable
  • HIPAA 164.312(b): Requires integrity controls → blockchain perfect fit

Trade-off:

  • Storage: 10x higher (hash chains)
  • Performance: Mining overhead (acceptable for audit logs)
  • Value: Cryptographic proof for auditors, regulatory confidence

Decision 3: Zero-Knowledge Proofs (vs Trust-Based Attestation)

Rationale:

  • Attestation: “Trust us, PHI never left” → not auditable
  • ZKP: Cryptographic proof PHI never transmitted → verifiable by regulators

Trade-off:

  • Complexity: zk-SNARK circuit design
  • Performance: 1-10s proof generation (acceptable, one-time per round)
  • Value: Mathematical guarantee vs procedural trust

Decision 4: Adaptive Privacy Budget (vs Fixed ε per Round)

Rationale:

  • Fixed ε: Wastes privacy budget on late rounds (diminishing returns)
  • Adaptive: Allocate more ε early (critical learning), less late (fine-tuning)

Trade-off:

  • Complexity: Dynamic budget tracking
  • Risk: Premature exhaustion if early stopping fails
  • Value: 5-10% accuracy improvement for same total ε

Decision 5: FedML/Flower Integration (vs Proprietary Protocol)

Rationale:

  • Proprietary: Vendor lock-in, limited ecosystem
  • FedML/Flower: Standards-based, interoperable, 1000+ researchers

Trade-off:

  • Flexibility: Must support multiple frameworks
  • Development time: 2 weeks for adapters
  • Value: Market credibility, faster adoption
