Proof of Creation System

Our innovative approach to establishing digital authenticity and provenance

1What is Proof of Creation?

Proof of Creation is our quantum-resistant method for establishing when and by whom a digital asset was created. It combines cryptographic hashing, digital signatures, and blockchain anchoring to create an immutable record of digital content.

2Creating a Proof

When you upload a file, our system generates a unique cryptographic hash using quantum-resistant algorithms. This hash is then signed with post-quantum signatures and recorded in our transparency log. For additional security, proofs are batched and anchored to a blockchain, creating a tamper-evident timestamp.

3Verification Process

Anyone can verify the authenticity of a file by uploading it to our verification service. The system recalculates the file's hash and compares it to our transparency log. If a match is found, the verification confirms when the proof was created, by whom, and whether it has been tampered with.

Key Benefits

Protected against both classical and quantum computing attacks

Tamper-Evident

Any modification to the original file will be immediately detected

Immutable Record

Blockchain anchoring ensures proofs cannot be altered or deleted

Verifiable Anywhere

Public verification system works without requiring trust in our service
