How does art authentication work?

Veriroo Editorial — Provenance & Authentication

Art authentication is the process of establishing that a work is genuine — that it was created by the artist to whom it is attributed, that it has not been significantly altered, and that there are no serious disputes about its history or ownership. For high-value works, authentication can be the difference between a work being worth millions and being worthless. For contemporary works, it is the foundation of buyer confidence.

What authentication involves

There is no single standard process for authenticating a work of art. The approach depends heavily on the type of work, the period, and the purpose of the authentication. For a contemporary painting being sold for the first time, it might involve nothing more than the artist confirming authorship and providing creation documentation. For a work attributed to a deceased master, it might involve forensic paint analysis, infrared imaging, archival research, and opinion from multiple experts.

In general, authentication draws on four main types of evidence: physical examination of materials and technique, stylistic analysis comparing the work to the attributed artist’s known output, provenance research tracing the work’s history, and documentary evidence such as correspondence, invoices, or exhibition catalogues.

Who performs authentication

Authentication is typically performed by experts with specialist knowledge — scholars who have studied a particular artist or period in depth, conservators with technical expertise, auction house specialists, or independent authentication boards established specifically for certain artists’ estates.

Not all authentication carries the same weight. An opinion from the leading scholar on a particular artist, backed by decades of research, is far more authoritative than a certificate issued by an unknown party. Buyers should understand who performed the authentication and what their credentials and methodology actually are before relying on a certificate.

Authentication vs. verification

In the context of contemporary art platforms, it is worth distinguishing between authentication and verification. Authentication typically addresses the question of whether a work is genuine and correctly attributed. Verification, as used on Veriroo, refers to the process of independently examining and documenting a work’s provenance, condition, and identity — and recording the results in a formal report that becomes part of the permanent provenance chain.

On Veriroo, independent expert verifiers can be commissioned at the point of sale. The verifier’s identity, credentials, methodology, and the date of examination are all recorded permanently on the provenance record. This creates a level of transparency about the authentication process itself that traditional paper certificates cannot provide.

The problem with paper certificates

For decades, the Certificate of Authenticity was a piece of paper — easily lost, easily faked, and entirely disconnected from any live record of the work’s history. A certificate that cannot be independently verified is worth little more than the paper it is printed on. The art world has a long history of forged certificates accompanying forged works.

Digital provenance platforms address this by making the certificate itself a live, tamper-evident record rather than a static document. On Veriroo, scanning the QR code on any Certificate of Authenticity shows the full provenance record — creation history, ownership chain, expert verification reports, and the current ownership status — in real time. The certificate is not a piece of paper in a drawer; it is a window into the work’s complete verified history.

What Expert Verified status means on Veriroo

On Veriroo, Expert Verified is the highest trust tier available. It means that an independent, credentialled verifier has physically or digitally examined the work, assessed it against the provenance record, and issued a formal report. The verifier’s identity, role, organisation, inspection method, and the date of the examination are all permanently recorded on the provenance chain.

This is not a self-declared status. It cannot be purchased or awarded without an actual examination by an actual expert. For buyers, it is the strongest trust signal available on the platform — the equivalent of a formal authentication from a credentialled specialist, recorded permanently and accessible to any future owner.
