Legal Document Verification

Every document you send carries its own proof

Tamper-evident verification with an independent cryptographic audit trail. Alterations are detected the moment a document is verified, and Blind mode keeps privileged content encrypted on your side.

Patent Pending
Evidence

Built for Legal Evidence Workflows

Every feature designed for legal professionals who need independently verifiable proof of document authenticity.

Instant Proof of Authenticity

Present independent, cryptographically verifiable proof of document integrity that any judge or opposing counsel can check on the spot.

Tamper-Evident: Any Alteration Visible

Even a single byte change triggers a visual forgery alert. The live holographic stamp freezes red — immediate, visible evidence that the document has been altered since issuance.

A Cryptographic Audit Trail Built for Evidence

Every document is cryptographically sealed with a timestamp, creating a chain-of-custody record that any party can independently verify and that cannot be altered after issuance.

Blind Mode: Client Confidentiality by Encryption

In Blind mode, privileged documents are encrypted in your browser before upload — Vertifile processes ciphertext and fingerprints, not readable content. Attorney-client privilege stays where it belongs: with you.
