H33 Launches HATS: A New Standard for Proving How Sensitive Data Is Handled

Miami, FL — April 25, 2026 — H33 today announced the release of HATS (H33 Attestation Trust Standard), a cryptographic attestation framework that continuously proves how sensitive data is handled across AI systems, financial infrastructure, and enterprise environments.

HATS introduces a new category: verifiable decision infrastructure — where systems don’t just make decisions, but produce independent, mathematical proof of how those decisions were made.

The Problem

Modern systems process sensitive data across increasingly complex pipelines — AI models, APIs, third-party services, and distributed infrastructure.

Today, organizations rely on logs, policies, and periodic audits to claim that data was handled correctly.

None of these prove what actually happened.

The HATS Approach

HATS does not attempt to control how systems operate. Instead, it cryptographically attests to what actually occurred.

For every decision, HATS produces verifiable proof of:

• What data was used (without exposing the data)
• How it was processed
• Whether it remained protected or was exposed
• Which policies were followed or violated
• The resulting output

These attestations are:

• Continuous (not point-in-time audits)
• Cryptographic (not logs or reports)
• Independently verifiable (by any third party)

How It Works

HATS combines:

• H33-74 attestations — fixed-size post-quantum proofs of computation
• Zero-knowledge STARK proofs — to validate execution without exposing data
• Post-quantum signatures (Dilithium) — ensuring long-term integrity

The result is a compact, verifiable record of how each decision was made — without requiring access to the underlying data.

What HATS Enables

With HATS, organizations can:

• Prove data was protected during processing
• Detect and attest to plaintext exposure or policy violations in real time
• Provide regulators, insurers, and partners with independent verification
• Move from trust-based compliance to proof-based compliance

If a system processes sensitive data incorrectly, HATS does not block it — but it detects it, proves it, and surfaces it immediately.

A Shift from Trust to Proof

“Most systems can tell you what they intended to do. HATS proves what actually happened.”

This distinction is critical as organizations deploy AI and automation into environments where decisions must be auditable, data exposure carries regulatory and financial risk, and trust alone is no longer sufficient.

Availability

HATS is available as part of the H33 platform and can be integrated into existing systems without requiring infrastructure changes.

The HATS standard is publicly available at h33.ai/standards/hats. Live demos are available at h33.ai/hats/demo.

Every decision your system makes. Proven. Permanently.
