Beyond signatures. Proof of every action.

A signature proves who agreed. But who viewed the document? Which version did they see? When was the approval given? What changed after that? The Digital Evidence Layer records every action across every IdentiGate product — timestamped, sealed, and tamper-evident. A complete chain of custody that travels with the document.

For: Legal · Compliance · Internal Audit · Risk · Any organization where "if you didn't write it down, it didn't happen."

Every line is timestamped, sealed, and tamper-evident

Signatures prove agreement. Evidence proves everything else.

In a dispute, the question is rarely "was this signed?" It's: "Did they actually see the document before signing? Which version? Was it changed after approval? Who had access? When?" Without a tamper-evident evidence trail, you're relying on email threads and memory. With it, you have court-ready proof.

⚖️

"I never saw that version"

The evidence layer records exactly which version of the document was viewed, by whom, and when. Version disputes become impossible.

🔄

"It was changed after I approved"

Every modification is recorded with before/after state. The evidence trail proves whether the document was identical to what was approved.

🕵️

"Who had access to this file?"

Complete access log: who viewed, downloaded, shared, or printed. Every action attributed to a verified identity — not just a username.

What the evidence layer records

Every interaction. Every participant. Every moment.

👁️

Views & access

Who opened the document, which version they saw, how long they viewed it, from which device and location. Every view by a verified identity.

Approvals & decisions

Who approved, who declined, who requested changes. Each decision timestamped and linked to the exact document version that was reviewed.

✍️

Signatures & seals

Every signature and seal event: who signed, when, with which certificate, which OCSP response was received, which timestamp was applied.

🔄

Changes & versions

Document modifications, version history, what changed between versions. If a document was altered after signing, the evidence trail shows it.

🔗

Delegation & authority

Who delegated signing authority, to whom, when, with what scope. Every delegation grant and revocation recorded and timestamped.

📨

Sharing & delivery

Who the document was shared with, when they received it, when they first opened it. Proof of delivery and receipt — cryptographically sealed.

What makes this different

Not an activity log. Tamper-evident cryptographic proof.

Most platforms keep activity logs — simple database records that say "user X did Y at time Z." These logs can be edited, deleted, or questioned in court. They're evidence about as strong as a sticky note.

IdentiGate's evidence layer is fundamentally different. Every event is cryptographically sealed — hashed, timestamped, and chained. Modifying a single record would break the chain and be instantly detectable. The evidence is attributed to verified identities — not usernames. And it's embedded in the document, so it travels with the file itself.

"If you didn't write it down, it didn't happen." With IdentiGate, it's written down — cryptographically — and nobody can un-write it.

Use cases

When proof of actions matters as much as proof of agreement

Contract disputes

"They changed the terms after I approved." The evidence layer proves exactly which version was approved, by whom, and that no changes were made after approval.

Regulatory compliance

Auditors ask: "Show me the approval chain for this document." One export: every view, approval, signature, and timestamp. Audit-ready in minutes, not weeks.

Insurance claims

Was the damage report filed before or after the incident was reported? Timestamps prove sequence. Evidence proves the document wasn't backdated.

Supply chain & logistics

Complete chain of custody: who loaded, who transported, who inspected, who received. Every handoff signed and sealed. Missing or unauthorized steps are immediately visible.

Internal investigations

Who accessed the confidential file? When? Did they download it? The evidence trail answers without relying on IT to pull server logs.

Intellectual property

Prove that your design, invention, or concept existed at a specific date. Timestamp + seal = prior art evidence that holds up in patent disputes.

Why this matters

Automatic — no extra effort

The evidence layer runs across all IdentiGate products automatically. Every action in the Signing Portal, every API call, every verification — recorded without any additional integration.

🔐

Tamper-evident by architecture

Events are cryptographically hashed and chained. Modifying, deleting, or reordering any record breaks the chain — and is instantly detectable. Not even IdentiGate can alter the evidence.

👤

Identity-attributed, not username-attributed

Every event is linked to a passport-verified person or verified company — not a username that could be shared or compromised. The evidence is as strong as the identity behind it.

📄

Travels with the document

The evidence record is embedded in (or attached to) the document itself. Even if you change platforms, change providers, or change nothing for 10 years — the evidence is still there, still verifiable.
