Audit Receipts

Tamper-evident evidence records that capture every AI-assisted financial decision — what happened, why, and what was decided.

What are Audit Receipts?

An audit receipt is a tamper-evident record that captures every aspect of an AI-assisted financial decision. It is the authoritative evidence document that compliance teams, auditors, and regulators can rely on to understand exactly what happened.

Unlike traditional logs or audit trails, Rosetta audit receipts are designed to be complete, immutable, and independently verifiable. Each receipt contains everything needed to reconstruct and validate the decision process.

Tamper-Evident

Each receipt is cryptographically sealed. Any modification invalidates the seal.

Immutable Chain

Receipts can be linked in chains, providing a complete decision history.

Independently Verifiable

Receipts can be verified by third parties without access to the originating system.

What Evidence is Captured

Each audit receipt captures a comprehensive set of evidence fields designed to provide complete decision transparency.

This is a conceptual example showing the type of evidence fields a receipt would contain. Actual receipt format and fields may differ in the production implementation.

Receipt Structure

Each audit receipt is organized into several sections that together provide a complete picture of the decision event.

Decision Context

What type of decision was made, which application initiated it, and what workflow was involved.

Policy Evaluation

Which policies were evaluated, their results, and any policy violations or warnings.

Risk Assessment

The calculated risk score, contributing factors, and any risk signals detected.

Review Status

Whether human review was required, who reviewed it, and what action they took.

Evidence Artifacts

Model outputs, input data snapshots, and any supporting documentation.

Cryptographic Seal

A tamper-evident seal that enables independent verification of receipt integrity.

Tamper Evidence

Every Rosetta audit receipt includes cryptographic protections that make tampering detectable. While the specific implementation is still being refined, the principle is straightforward:

Each receipt is hashed and signed at creation time.
Receipts can be linked in a chain, where each receipt references the previous one.
Any modification to a receipt invalidates its cryptographic seal.
Verification can be performed by anyone with access to the receipt and the public verification key.

Development Status

The audit receipt format, cryptographic implementation, and verification mechanisms are still in development. The examples shown here are conceptual and subject to change. We do not claim production-ready receipt functionality at this stage.
