Authenticity
How Vitella verification works
A hologram can be reproduced. A serial number can be guessed. We use neither. Every Vitella unit carries a code that is cryptographically signed, registered against its production batch, and counted every time anyone checks it.

The QR code and the printed characters carry the same code, so you can verify with a camera or by typing.
The mechanism
Why these codes cannot be faked
Three properties do the work. Together they mean a counterfeiter can copy the printing but not the system behind it.
Signed, so they cannot be invented
Each code is 10 characters: eight drawn at random, then two derived from a cryptographic signature of the first eight using a key that never leaves our servers. Without that key, the odds of producing a code that even passes the signature check are about one in a thousand — and it would still have to exist in our register.
Random, so they cannot be predicted
Codes are not sequential and carry no date or batch information in the characters themselves. Knowing one code tells you nothing whatsoever about any other. There are over a trillion possibilities, and we issue a vanishing fraction of them.
Counted, so copies expose themselves
The one attack that always works against printed labels is photographing a real one and reprinting it. We cannot stop that — but every copy reports to the same code, so the scan count climbs abnormally and tells us the label has been cloned.
Reading the result
What each answer means
- Authentic
Issued by Vitella
The code is in our register. We show you the product, the production batch, and whether it has been checked before. A brand-new unit should read as a first check.
- Checked often
Genuine code, unusual pattern
The code is real but has been verified far more often than one unit plausibly would be. Sometimes that is a shop display; sometimes it means the label has been copied. Either way we want to hear from you.
- Not registered
Never issued
The code has the right shape but is not in our register. If it came off a product label rather than a typo, that product is almost certainly counterfeit.
- Withdrawn
Removed from circulation
We have blocked this code — normally because it was found on counterfeit stock. Do not treat the item as genuine.
Being straight with you
What this system does not do
Any brand-protection claim that sounds absolute is overselling. Here is the honest boundary of what a printed code can prove.
It proves the code is ours, not that the item is
A verified code means Vitella issued that code. If someone photographs a genuine label and applies it to a copy, the code still verifies — which is precisely why we count checks and ask you to contact us when the count looks wrong.
A first check is strong, but not proof on its own
The most reassuring result is a code that has never been checked before, on a sealed unit you bought from an authorised distributor. Those three things together are what make it convincing.
We rely on customers telling us
Scan patterns are only a signal. Reports from people who noticed something wrong are what turn a signal into action.
Privacy. Verifying a code does not require an account and does not identify you. We record the code, the time, an approximate country and a salted one-way hash of your IP address — enough to count distinct checks, and not enough to identify a person. Full privacy notice.
