The Threat

The Risk: AI + Financial Data Exposure

AI fraud detection systems process account numbers, transaction histories, and behavioral patterns. Traditional systems decrypt to analyze — creating an exposure window at every stage of the pipeline.

🔍

Plaintext Processing Windows

Every fraud model that ingests raw account data creates a window where that data exists unencrypted in memory. One compromised node, one rogue process, one core dump — and account numbers, SSNs, and transaction histories are exposed.

📋

Log & Cache Leakage

Fraud scoring pipelines generate intermediate results, debug logs, and cache entries containing financial PII. These artifacts persist in infrastructure you don't fully control — cloud provider caches, CDN edge nodes, observability platforms.

👤

Insider Threat Vectors

Any engineer with access to the fraud detection pipeline has access to raw financial data. Database admins, DevOps, ML engineers, vendor contractors — each is a potential exfiltration vector. Traditional DLP cannot prevent authorized access abuse.

⚠️

Regulatory Exposure

GLBA, PCI DSS, SOX 404, and state-level privacy laws impose strict data handling requirements. A single compliance failure can result in regulatory action, consent orders, and fines that dwarf the cost of the security program.

🌍

Cross-Border Data Residency

Global banks must comply with data residency requirements across dozens of jurisdictions. Moving financial data across borders for centralized fraud analysis creates compliance exposure that FHE eliminates by keeping data encrypted in transit and at rest.

💣

Harvest Now, Decrypt Later

Nation-state adversaries are capturing encrypted financial data today to decrypt when quantum computers mature. RSA and ECC-protected transaction records have a shelf life. Post-quantum encryption from H33 ensures financial data remains protected against future threats.

The Bottleneck

Why Traditional Security Slows Banking Systems

Encryption adds latency. Banks need sub-millisecond decisions for real-time payments, trading, and fraud scoring. Every millisecond matters. Traditional DLP scans add 50–200ms of overhead — overhead that H33 eliminates entirely.

Traditional Security Stack

DLP scan (decrypt + inspect + re-encrypt) 50–200ms
Tokenization lookup 5–15ms
Format-preserving encryption 2–8ms
Key management round-trip 10–50ms
Total added latency 67–273ms

The Architecture

How FHE Protects Financial Data at Wire Speed

H33 runs fraud detection, behavioral analysis, and compliance checks on fully encrypted data. 38.5µs per operation. No decryption, no plaintext window, no exposure. The fraud model sees ciphertext and produces a match score — without ever accessing the underlying financial data.

Step 1
Encrypt at Source
Financial data — account numbers, transaction amounts, behavioral signals — is encrypted using BFV homomorphic encryption at the point of origin. Private keys never leave your HSM.
<1ms encryption
Step 2
Compute on Ciphertext
H33's FHE engine runs fraud scoring, velocity checks, and behavioral analysis directly on encrypted data. The AI model processes ciphertext and produces encrypted results.
38.5µs per auth
Step 3
Attest & Prove
Every computation is signed with Dilithium post-quantum signatures and verified with ZK-STARK proofs. Cryptographic proof that the computation was performed correctly on your encrypted data.
291µs attestation
Step 4
Decrypt Locally
Only your infrastructure decrypts the result. H33 returns an encrypted fraud score. You decrypt with your private key and apply your own decisioning rules. Full autonomy, zero exposure.
Your key, your decision

Consortium Intelligence

Cross-Bank Fraud Intelligence Without Data Sharing

H33-Share enables banks to share fraud signals without exposing customer data. FHE-encrypted signals are accumulated homomorphically. Each bank contributes encrypted fraud indicators; the aggregation produces intelligence without any bank seeing another's raw data.

1

Each Bank Encrypts Locally

Fraud signals — entity feature vectors, velocity indicators, confirmed fraud markers — are encrypted using BFV homomorphic encryption inside each bank's HSM. Private keys never leave the institution.

2

Encrypted Signals Aggregate

H33 receives encrypted contributions from all consortium members. Homomorphic addition accumulates fraud indicators on ciphertext. No bank's raw data is visible to H33 or any other member at any point.

3

Intelligence Without Exposure

Consortium queries return encrypted risk scores computed across all member contributions. Only the querying bank can decrypt its own results. ZK-STARK proofs verify computation integrity without revealing inputs.

4

Flywheel Effect

Each confirmed fraud alert makes the network smarter for every member. Banks that contribute more fraud intelligence receive higher query quotas and better pricing — incentivizing participation and improving detection accuracy across the consortium.

Zero bytes of plaintext data shared between institutions. Ever. Verified by ZK-STARK proofs and post-quantum Dilithium signatures.
