ZERO-KNOWLEDGE LICENSING

We Sign Your License.
We Never See It.

The first licensing system where the vendor mathematically cannot identify customers. Not "won't" - cannot.

Traditional vs VU Licensing

Traditional Licensing

Server stores: Name, Email, Payment info
License tied to your identity
Usage tracked and logged
Data can be subpoenaed
Breaches expose customers
Requires internet for validation

Privacy by Policy

VU Anonymous Licensing

Server stores: Nothing about you
License has no identity attached
Zero tracking possible
Nothing to subpoena
Breaches reveal nothing
Works 100% offline

Privacy by Mathematics

The Five Steps to Anonymous Licensing

🎲

Step 1 of 5

You Generate

A random 512-bit license seed

Your device creates a completely random license identifier. This happens entirely on your device - we never see it.

crypto.getRandomValues(new Uint8Array(64))

What VU Knows About You

👤

Your Identity

Unknown

Monero payments are unlinkable. We receive funds without sender information.

🎫

Your License

Unknown

Blind signatures mean we sign without seeing. Mathematical certainty.

📊

Your Usage

Unknown

Offline verification means we're never contacted. Zero telemetry.

🔗

Payment ↔ License Link

Impossible

The blinding factor is destroyed after use. No way to correlate.

Legal Implications

Even with a court order, subpoena, or government demand, we cannot provide information about who purchased licenses because we do not possess this information. This is not a policy choice - it is a mathematical certainty built into the cryptographic protocol itself.

The Mathematics

RSA Blind Signatures

Invented by David Chaum in 1983, blind signatures allow a signer to sign a message without seeing its contents. VU uses RSA-2048 with a 512-bit license seed.

Blinding: L' = L × r^e mod n

Signing: S' = L'^d mod n

Unblinding: S = S' × r^-1 mod n

Verification: S^e mod n = L

Monero (XMR) Payments

Monero uses ring signatures, stealth addresses, and RingCT to make transactions completely untraceable. We verify payment occurred without knowing who sent it.

Ring signatures hide sender among decoys
Stealth addresses hide recipient
RingCT hides transaction amounts
No blockchain analysis possible
