nüme: Biometric Passports and Blockchain Art Certification

nüme is a French technology company, headquartered in Biarritz, dedicated to securing the future of the art market through advanced digital authentication. Founded by Damien and Franck Dupont, the organization specializes in creating markerless biometric passports for physical artworks. Their process involves robotic scanning at resolutions up to 4000 dpi, capturing intricate details such as pigment composition, UV responses, and craquelure patterns. These characteristics are converted into a unique visual hash and stored on a blockchain, effectively making the artwork its own proof of authenticity. This non-invasive method eliminates the need for physical tags or QR codes, preserving the integrity of the piece while providing institutional-grade security. nüme's technology is utilized by prestigious cultural institutions, including the Louvre, to document condition reports and track provenance with absolute transparency. By integrating artificial intelligence and distributed ledger technology, nüme offers a comprehensive suite of solutions for collectors, curators, and insurers, ensuring that every artwork in their care is documented, secured, and accessible through a secure digital identity.
