Web Commodore Digital Proof

Record and prove the integrity of your data logs

Prove data log integritySecurely fingerprint and timestamp your log data as evidence of existence and integrity

In the world of big data, system logs, sensor logs, security logs and other timed data logs have become prevalent in many industries. But how do you prove the integrity and existence in a certain point in time whilst keeping your log data confidential?

Web Commodore Digital Proof helps you prevent tampering or disputes of timing and ownership of your data logs, without the need to upload or disclose them.

Incorporating a secure fingerprint of your log data along with an accurate time stamp, Web Commodore Digital Proof Tokens are admissible as evidence in court and help prevent tampering or misuse.

Secure Digital Proof Tokens

Digital Proof Token Encryption

Web Commodore Digital Proof Tokens are generated using a locked-down Hardware Security Module (HSM) certified to FIPS 140-2 Level 3 standard for all cryptographic operations

Trusted time stamping authority

Trusted Time Stamp

Web Commodore is a trusted Time Stamping Authority (TSA). All Digital Proof Tokens are signed in accordance with the IETF RFC3161 industry standard with a date and time stamp accurate to within 3 milliseconds, synchronised to the Coordinated Universal Time (UTC)

Secure digital proof storage and blockchain registration

Digital Proof Token Security

Web Commodore uses security standards-compliant systems for all its operations and uses a private RSASSA-PSS 3072 bit security key locked down in a FIPS 140-2 Level 3 HSM module to sign all Digital Proof Tokens. Digital Proof Tokens are registered as non-fungible tokens (NFT) on the GoChain public blockchain.

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
