EvidenZ Framework

EvidenZ allows to deploy registers on the blockchain for all types of high value data. It is intended to enable institutions, companies and universities to issue certified data over the long term, while respecting the regulations concerning personal data (GDPR, and especially the “right to be forgotten”). It provides individuals with a direct and permanent access to data through a simple URL on which anyone can click for free. EvidenZ was patented in the US in 2018.

what’s new with EvidenZ?

What’s new with EvidenZ?

All organizations is able to issue "one click certified" data with a simple DApp. All individuals is able to share certified personal data, without having a blockchain wallet. EvidenZ has invented the "right to be forgotten" on the blockchain.

What’s EvidenZ DNA?

EvidenZ does not store documents or their hash fingerprints, but only encrypted data directly on the blockchain. EvidenZ generates trust by validating the identity of data issuers first. EvidenZ is an open source, so that the access to data remains unlimited over time.

why is EvidenZ secured?

Why is EvidenZ secured?

Only an organization whose identity has been verified can issue data. The EvidenZ cryptographic protocol guarantees the control of the access to data and the “right to be forgotten”. The data stored by EvidenZ cannot be modified or collected, or exploited for commercial purposes.

EvidenZ's innovation combines:

  • Full traceability of the information stored in a decentralized way
  • A maximum level of program and data security
thanks to the use of smart contracts and a high-level cryptographic algorithm.

Smart Identification

An “ID Certificate” is issued, stored and readable by all on the blockchain after validation of the identity and address of the institution.

Smart Identification

Smart Publication

The institution certifies its data through a DApp, which encrypts and publishes it through a transaction on the blockchain. The DApp generates a Shamir's Secret Sharing and the corresponding decryption keys and the URL by which the data will be available.

Smart Identification

Smart URL

A simple click is all it takes in order to consult the data. The DApp reconstitutes the decryption key, using three keys: the graduate key (URL), the persistence key, and the permanent key. The data thus published is accessible with a simple click through the generated URL. A DApp reconstructs Shamir's Secret Sharing using three keys: the certificate holder's key (URL), a persistence key (erasable, allowing the right to forget), and the issuer's key.
