Veintree is all about locks and keys, but digital locks and keys based on your physical unique characteristics.

A specific digital lock is created when you wish to access a digital service, a digital right or a physical place to which you have been granted access by a "custodian of the premises".

But the lock contains nothing about you, no information whatsoever, and is only capable of receiving a specific code that will enable it to be opened.

And this code, which we call a token, is constructed from your hand, and several other pieces of non-personal information.

This token is designed to be resistant to quantum computation... and that's unique...

What's more, it can only be used only once! 

2 tokens can never be identical... 

It's this token which will (or won't) combine with the lock and open it (or not).
