Patented SAIFE Document Integrity
SAIFE Only-Version Documents
Turn important files into verified Only-Version documents. SAIFE fingerprints, reads, certifies, serializes, packages, and records document integrity so recipients can confirm whether a file is the registered original, a SAIFE Certified Copy, an altered copy, or an unknown imposter.

What Only-Version means
A normal document can be copied, renamed, edited, exported, or impersonated. A SAIFE Only-Version document receives a unique serial identity, certificate, activity ledger, public or private proof surface, and layered integrity fingerprints so anyone with permission can verify whether a file is the official version.
What SAIFE checks
• exact file fingerprint
• canonical content fingerprint
• extracted text fingerprint
• metadata and structure signals
• certificate and serial identity
• certified-copy imprint markers
Registered Original
The official document registered into SAIFE. Verification can confirm the received file matches the original Only-Version proof.
• Best for final contracts, policies, records, certificates, filings, and evidence.
• Backed by serial ID, certificate hash, fingerprints, and activity ledger.
SAIFE Certified Copy
A recipient-safe file generated from a registered record. It can carry SAIFE verifier-readable imprint metadata so future holders can validate authenticity.
• Best for sending copies to customers, agencies, counterparties, auditors, or attorneys.
• Phase 1.5 uses safe non-destructive certification strategies.
Portable Verification Package
A downloadable package containing certificate proof, registry proof, manifest, instructions, ledger summary, and advisor summary.
• Best when sending formal proof alongside a document.
• Designed to work across file types and recipient workflows.
How it works
SAIFE creates an integrity path from registration to certified distribution to independent recipient verification.

Recipient workflow
Send the document. Let the recipient verify the truth.
Only-Version is built for real-world handoff: contracts, policies, evidence, investor documents, government records, and any high-trust file that may be forwarded, downloaded, attached, or challenged later.
Sender
Registers the official document, downloads a certified package, generates a SAIFE Certified Copy when needed, and sends the file plus proof link to the recipient.
Recipient
Opens the certificate or registry proof link, uploads the file they received, and sees whether it is original, certified, altered, possible imposter, or unknown.
Auditor / Attorney
Reviews the certificate, activity ledger, fingerprints, registry state, advisor notes, and verification result history.
Business workflow
During negotiation, drafts can change. When the final version is approved, SAIFE registers the official copy and makes later tampering detectable.
Real-world use cases

The future of document integrity is verifiable.
As AI makes it easier to rewrite, forge, summarize, impersonate, or manipulate files, SAIFE gives organizations and recipients a trusted way to verify the document itself.
