How it works: Web Commodore Digital Proof Token Generation

1A unique fingerprint (sha-256) of the digital file is generated by the browser and transmitted to Web Commodore.

2The fingerprint is combined with an accurate timestamp.

3The fingerprint / timestamp combination is encrypted using a locked-down Hardware Security Module (HSM)

4Together with a public key to provide authenticity, this generates a Digital Proof Token

5The Digital Proof Token is registered on the GoChain public blockchain

6The ownership and integrity of the digital file can be verified at any time
