Data Verification (MSD)
Prove where every extracted value came from
Every field Staple extracts carries a record of where it came from: source document, extraction time, model version, and confidence level. A built-in audit trail from document to ERP that you can verify on demand.
The problem: extraction without proof
Your document processor extracts a figure from an invoice and puts it in your ERP. Six months later, an auditor asks where that figure came from.
Your team searches email, shared drives, and filing cabinets. They match timestamps, cross-reference file names, and rebuild the chain from memory and metadata. Two people spend a week on it. They produce a narrative, not proof.
This works when auditors give two weeks of notice and a narrow scope. It stops working when a regulator asks for field-level evidence across six months of transactions within 48 hours. Asian language characters and jurisdiction-specific compliance requirements make reconstruction harder still.
Every document processor on the market has this gap. They extract data. But they do not prove where it came from.
Every extracted field carries its own verification record.

How Staple verifies data
Every field carries its own audit trail
When Staple extracts data from a document, it attaches a verification record to every field at the moment of extraction. This verification layer is called Metastructured Data (MSD). It allows the audit trail to be a property of the data itself, not a log you search through. No additional configuration. No separate logging system.
Retrieve evidence, do not reconstruct it
When an auditor or regulator requests traceability, you query the field. Staple gives you the source document, extraction time, processing model, and confidence score. What used to take two people and a week becomes a query that returns in seconds.
Verify nothing has changed
If a value is changed after extraction, either in transit, in storage, or in your ERP, the verification record breaks. You can confirm at any point that the data in your system matches what was extracted from the source document. This is the difference between “we have an audit trail” and “we can prove the data has not been altered.”
Built for AI governance frameworks
AI governance frameworks like ISO 42001, the EU AI Act and Singapore's MAS AIRG, all require the same thing: show how the AI arrived at this output. Metastructured Data provides that evidence at the field level, and embeds it in the data itself.
Technical details
MSD is an open standard. Any system, not just Staple, can produce and consume MSD-compliant data.
What the Metastructured Data contains for each field:
Source document reference
Extraction timestamp
Processing model and version
Confidence score
Cryptographic signature
Integration
MSD travels with each field through your existing integrations. No additional middleware or logging infrastructure required
Line-item Matching
An invoice can match at the header level while hiding line-item discrepancies. Staple compares every row (price per unit, quantity, item code) against corresponding source documents. Arithmetic doesn't hold? It's flagged before it reaches your ERP
Multilingual Document Processing
300+ languages with native Asian Language script processing, including handwriting and rubber stamps
