Example of Artwork Certificate

Exclusive Artwork Certification · How It Works

All exclusive artworks presented in this catalogue follow a documented and technically grounded certification process, designed to ensure authenticity, uniqueness, and long-term protection.

Certification is not limited to a descriptive statement. Each artwork is accompanied by a formal document that records its essential data together with a unique cryptographic identifier.

What is a cryptographic hash?

A hash is an alphanumeric sequence generated by a mathematical algorithm from a specific file or document. Any modification, even minimal, results in a completely different hash.

In practical terms, a hash functions as a digital fingerprint: it uniquely identifies a document without revealing its contents.

Why is it used in artwork certification?

The hash is included in the certificate to provide:

  • Technical proof of document integrity
  • Immediate detection of any alteration
  • Long-term documentary traceability
  • An objective reference for future verification

In this way, exclusivity is no longer merely conceptual and becomes technically verifiable.

What the collector gains with a certified exclusive artwork

  • Ownership of a unique artwork, with no future reproductions
  • Clear and documented certification
  • Technical proof of authenticity and uniqueness
  • Protection against unauthorized use or exploitation
  • Preservation of artistic and patrimonial value
