How does it work?
Validity enables anyone to sign data and to associate their signature with their email address, social media, or website.
Choose your document
The proof of signature is secured
With Validity :
Validity relies on Blockchain technology
The signature is stored on the blockchain, and is therefore not centralized, for maximum security.
It is impossible for anyone to modify the signature once stored on the blockchain.
Each insertion of a signature is accompanied by a UTC timestamp, directly supported by the blockchain.
Access to the signature can be done independently of the Validity service. It is thus very easy to carry out an audit.
