Art authentication · Cryptographic software
We authenticate paintings, sculptures, photographs and digital works with multispectral imaging and artificial intelligence, then seal each result with post-quantum cryptography. The certificate cannot be forged, and anyone can verify it in seconds.
RICHARD MILLE SAS is a Paris company of the ZEE group, dedicated to art authentication and cryptography. We are not affiliated with, endorsed by or connected to the Richard Mille watch brand or Richard Mille SA.
Our two activities
Scientific examination of the work, comparison with reference corpora and expert review. The result is a documented opinion, not a guess.
We design the software that seals certificates, protects keys and lets owners prove what they hold without revealing it.
Seeing beyond the surface
Each band reveals a different history of the work: retouching, underdrawing, pigments, repairs. Together they form a material fingerprint.
UV FLUORESCENCE · 365 nm
Shows later varnish and retouching that fluoresce differently from the original paint.
VISIBLE · 400 to 700 nm
Gigapixel capture of brushwork, craquelure and signature at microscopic scale.
IR REFLECTOGRAPHY · 1 to 2.5 µm
Reveals the underdrawing and changes of composition hidden beneath the paint layers.
X-RAY FLUORESCENCE
Maps the chemical elements of pigments. A titanium white in an 18th-century work raises a flag.
RAMAN SPECTROSCOPY
Identifies each pigment and binder molecule, then compares it with the dates of their invention.
STEP 1
Secure transport or on-site visit. Condition report and chain of custody open.
STEP 2
Multispectral capture and material analysis, without contact or sampling whenever possible.
STEP 3
AI comparison with reference works, style, materials and documented provenance.
STEP 4
Specialists of the period validate or challenge the findings and sign the opinion.
STEP 5
Certificate signed, digital twin registered, tamper-evident tag fixed to the work.
Analysis lab · Simulation
Choose one of two invented paintings, move the spectral loupe over it, then launch NEUTRINO PROVENANCE. Everything on this panel is a simulation: the artist, the works and the results are fictitious.

In collaboration with NEUTRINO
NEUTRINO is the ZEE group's sovereign hybrid quantum and classical artificial intelligence (French patent application FR 2601296). Its PROVENANCE module is dedicated to works of art. It cross-checks every imaging layer, every archive and every signature before an expert gives an opinion.
Cryptography software
A certificate of authenticity is only as strong as its signature. Ours rely on lattice-based algorithms standardised by NIST in 2024, designed to resist attacks from future quantum computers.
Signature
Signs every certificate and every change of ownership.
Key exchange
Protects files and images exchanged with clients and experts.
Fingerprint
Hashes the digital twin so the smallest change becomes visible.
Privacy
Lets a collector prove ownership without disclosing identity or price.
Verify a certificate
Scan the tag on the work or type its certificate number. The page checks the signature against our public key and shows the history of the work.
Demonstration only. This sample certificate is fictitious and the check runs locally in your browser.
Who we work with
Confidence before a purchase and a portable proof for the life of the work.
Pre-sale examination and certificates buyers can verify themselves.
Condition and identity records that make a claim or a recovery easier.
Scientific documentation of collections and secure archives.
Certificates issued at creation and a registry against forgeries.
