Audit evidence is built for reliability, not automatic reuse

Start here

Does any of this sound familiar?

• Your audit function keeps source documents, approvals, reconciliations, logs, and workpapers.
• Evidence depends on its origin, integrity, version history, and reproducibility.
• You need to protect retention duties, confidentiality, and ownership before AI use.

Audit evidence differs from an AI example. A workpaper, approval log, or exception record must support a conclusion and may need preservation under a regulatory, contractual, or litigation hold. A separate AI task must not alter the retained source.

File counts do not show readiness. Provenance, permission, audit history, decision labels, and a boundary between evidence and testing matter.

The problem

The transformation can damage the evidence trail

Copying evidence into a vendor workspace may create an uncontrolled record, conflict with retention, or expose regulated information. Redaction or extraction can remove context needed to recreate the original or explain changes.

Historical samples reflect control design at the time. A missing exception may indicate a capture gap, not that none occurred. Reviewers need the evidence, scope, and approval basis behind labels from prior audit conclusions.

Preserve the evidence first; evaluate a derivative only under a separate authority.

The solution

Keep evidence custody and AI evaluation on separate tracks

Before testing, map records without exporting them and ask records counsel about retention, regulator access, and holds.

DataSupply partners only with labs that meet its top 0.01% credibility standard. We help assess whether a qualified buyer may be a fit and negotiate terms that reflect the data's potential value, including exclusivity where relevant. We also help you work through diligence questions about rights, privacy, security, and compliance, then present a high-level inventory of permitted records, not the dataset. Fit is specific to each situation; no buyer or value is guaranteed.

What to inventory before any buyer conversation

• Identify the record and the control objective Document source, owner, retention schedule, control, approval, and any hold. Preserve the original under applicable policy.
• Classify each proposed use and derivative Separate internal search, evaluation, training, and licensing. For each derivative, record transformations, authorization, linkage risk, reviewer, and how to reconstruct the original.
• Log transfers, versions, and disposition If approved, log permitted files, version identifiers, recipients, transfer, access expiry, model, purpose, corrections, destruction, and verification. Keep sign-offs with the records schedule.

Set the boundaries before discussing access.

Security, records, audit, privacy, and legal owners should check obligations, holds, confidentiality, and vendor terms. Restrict access, encrypt transfers, prohibit unauthorized reuse, preserve the audit trail, and prevent overwriting the original. Do not move sensitive records before authorization.

What could make a permitted example useful?

A derivative or purpose-built evaluation set might help test control checks, but preparation and validation take effort and may create no commercial value. Integrity and authority come first.

A practical first step.

Ask the records owner to map one control workflow, retention, and allowed transformations. Begin with a paper inventory; do not send evidence to a vendor.

datasupply.ai can discuss possible fit and buyer questions without receiving your dataset. You decide whether to pursue any introduction. No buyer, license, or payment is guaranteed.

Documented example / what it proves

SEC electronic-record rules illustrate why change history matters

The SEC's 2022 amendments to Rule 17a-4 provide covered entities an electronic recordkeeping alternative based on a complete time-stamped audit trail. The trail includes changes, deletions, action times, and, where applicable, the person responsible, while enabling recreation of the original. Read U.S. Securities and Exchange Commission, Release No. 34-96034.

This record-integrity requirement supports separating controlled evidence from test copies. It does not make preserved records available for AI training or licensing.

The important limit: The SEC rule concerns specified recordkeeping obligations; it is not proof of a closed data license or permission to reuse covered records for AI.
