Is my file sent to the server?

No. SHA-256 hashing happens entirely in your browser. Only the hash is sent — never the original file.

What's the difference from e-signature?

E-signature proves who signed a document. VerixID proves a document's integrity and when it first existed.

Can the record be changed?

No. Records are write-once and cannot be modified or deleted during the retention period.

How much does it cost?

Submit is free forever. A Certificate of Authenticity (COA) is available per document. Forensic service is available on-demand based on case scope.

Does VerixID have an API for developers or AI agents?

Yes. VerixID provides a REST API for system integration and an MCP Server compatible with Claude, ChatGPT, and Cursor for AI agent use cases.

How It Works

Three steps. Verifiable proof.

Choose a file — any format

Your browser generates a unique fingerprint from the file. The file never leaves your device.
Only the fingerprint is sent

VerixID receives the cryptographic fingerprint, not the file content. We can't read your file because it's never sent to our server.
Get a Record ID for verification

The fingerprint and timestamp are recorded as proof. Share the Record ID so anyone can verify it independently.

Trust you can verify

Not a claim. This is how the system works.

Every point below can be tested independently.

Files are never stored

Your file is never uploaded or stored on our servers

Unique fingerprint

Every file is converted into a digital identity with guaranteed integrity

Active for 1 year*

Your digital proof is ready to verify anytime

Regulation-aligned

Built in line with Indonesia's ITE Law, PSTE Regulation & Personal Data Protection Law

Why VerixID

Because proof beats claims.

In the age of AI, file metadata is no longer enough. VerixID provides independent, cryptography-based proof of existence that can't be manipulated.

Time & Ownership

Shows who registered a file first and when it was first recorded on the ledger.

Data Integrity

Every file gets a unique integrity code. Even the smallest change is detected mathematically.

Open Verification

Records never store the file — only the fingerprint is recorded on the ledger. Anyone can verify it publicly, anytime, without access to our internal systems.

See VerixID's First Principle →

Every submission produces a unique Record ID you can share with clients or colleagues — they can verify it themselves, anytime, with no permission or account needed.

✅ Submit & Verify are free — no cost

✅ COA service — ready-to-use formal proof

✅ Forensic service on-demand for special cases

Proven, not claimed

We don't ask you to just take our word for it.

Like a notary that never sleeps — VerixID records every file's fingerprint with an immutable timestamp. The system is tested through an independent black-box approach, not self-assessment — the results are consistent and reproducible by anyone.

See our Independent Verification Report or read our Legal Basis & Compliance (Indonesia's ITE Law, PSTE Regulation, PDP Law).

For Developers & AI Agents

Need Integration? REST API • MCP Server

Connect proof recording and verification directly to your systems, workflows, or AI agents — no need to open a dashboard every time.

REST API

Submit a hash, check record status, and pull verification data directly from your system. Great for backend integration, e-signature platforms, or document management systems.

MCP Server

Give your AI agent the ability to record and verify digital proof natively — compatible with Claude, ChatGPT, and Cursor via the MCP protocol.

FAQ

Fair questions, straight answers.

: Correct. Hashing happens entirely in your browser. Only the fingerprint — a unique string of characters — is sent to our server, never the file content. You can verify this claim yourself through our independent security report.
: E-signature proves who signed a document. VerixID proves when a file was first registered and whether its content has changed since. The two serve different purposes and can be used together.
: No. Every record follows a write-once approach — there is no mechanism to modify or delete data once submitted. Records are automatically deleted after the 1-year retention period* ends.
: Records stay in the system for 1 year* from the submission date. During that period, public verification remains free. For formal legal purposes requiring complete documentation, our COA and on-demand forensic services are available.
: Yes. VerixID issues a digital COA for every registered file. The COA includes the fingerprint, timestamp, and a verification reference you can share with third parties. Learn more about what COA does →
: A VerixID COA is technical evidence referencing Articles 5 and 6 of Indonesia's ITE Law. Like most digital evidence, its use in court can be strengthened by a digital forensics expert's testimony. The final assessment rests with the judge based on the context of each case. Evidentiary rules vary by jurisdiction outside Indonesia.
: Yes. VerixID provides a REST API for direct integration into your systems, and an MCP Server compatible with Claude, ChatGPT, and Cursor so AI agents can record and verify digital proof natively. See Trust API or MCP Server.
: No, but the two can complement each other. Copyright gives you a legal right over a work. VerixID gives you proof that the work existed as of a certain time — and hasn't changed since.
: A file's fingerprint can be independently recomputed using the open SHA-256 standard — no VerixID system required. Any COA already issued remains usable as a reference document. Technical details are in our whitepaper.
