You can see the way Certidox is working.

AUTHENTICATED USERS benefiting from the Certidox authentication service

You must submit a proof of your identity,
Certidox authenticates your documents.

The way Certidox certifies a document in a few seconds

Certidox processes any kind of document.

After the user has uploaded its document in secure mode,

Certidox

1. Scans the document to make sure it doesn't contain any virus,
2. Creates a SHA256 hash of the document,
3. Creates a unique QR code for the document (= "proof of existence"),
4. Pastes the QR code in a Certidox-label on the document,
5. Saves the document in a database with the SHA256 of the document before and after affixing the CertiDox label containing the QR code AND mints on the Polygon blockchain an NFT (Non-Fungible Token) containing the SHA256 of the document and the ID number of the issuer that has been dynamically encrypted with the CRYPT_BLOWFISH algorithm.

Once the process is finished, the user can download its document authenticated by Certidox.

The QR code allows checking

The simultaneous existence of the document in the CertiDox database and on the decentralized Polygon blockchain,
The author of the document,
The status of the document: “still valid” or “revoked”.

IMPORTANT :

SHA256 is the fingerprint of a document. Even if a single symbol is changed, the algorithm will produce a different hash value: this makes it suitable for verifying the integrity of your data.
It is impossible to reconstruct a document from its SHA256
The NFT, which only contains the SHA256, therefore contains no readable information on the certified authentic document, which guarantees its confidentiality.
Documents certified authentic with Certidox cannot be consulted on the web but only through the Certidox App

He can then and disseminate it e.g. on its website, by mail and social media.

People will be able to check the document by launching the Certidox app on their Smartphone or their Tablet.
