Multi-modal forensic authentication

The eye is
not enough.

Connoisseurs see a surface. We read the body beneath it — the strain in the ground, the direction of every brushstroke, the spectral fingerprint no forger can repeat. Authenticity is not a verdict. It is a reading.

The wrong question

Genuine or fake?
The real question is: what is physically true?

A yes-or-no stamp throws away almost everything an object can tell you. Artentika replaces the binary with a body of evidence: historical, material, and mathematical — each finding carrying a quantified confidence, each report sealed immutably to the blockchain.

We are the world's first enterprise built at the intersection of art, technology and finance. We treat your artwork as an individual with an identity to be recognised — not an image to be matched.

The method · five movementsFull method →
01

Look

Connoisseurship, history and physical examination. The trained eye still comes first.

02

Multi-modal capture across material science, image processing and AI.

03

Compare

One-2-One© detects the minutest discrepancy between two captures across time.

04

Attest

A probabilistic determination, documented and sealed to the blockchain.

05

Watch

Ongoing condition monitoring — revealing change before it becomes a crisis.

The method

Five movements,
one determination.

Every artwork passes through the same disciplined sequence — from the trained eye, to the mathematics beneath the paint, to a sealed and defensible attestation.

01

Look

It begins where it always has — with the eye. Historical analysis, in-depth provenance research and physical examination establish the questions the object raises before any instrument is switched on. Connoisseurship is not replaced; it is given evidence.
02

Read

We capture the work across many modalities — material science, high-resolution image processing and AI. The principle is simple and patented: we do not compare pictures. We compare the mathematics beneath them. Surface colour is the least of what an artwork reveals.
03

Compare

Our One-2-One© solution detects the minutest discrepancy between two photographs of any object taken at different times. A capture from the Artentika App initiates an automated comparison that sees changes invisible to the naked eye.
04

Attest

Findings converge into a probabilistic authenticity determination, each carrying a quantified statistical confidence. The result is documented in full and sealed immutably to the blockchain — defensible in the boardroom, the salesroom and the court.
05

Watch

Authentication is a moment; an artwork's life is long. We monitor evolving condition over time, shaping conservation strategy, reducing cost, and — in select cases — revealing entirely new revenue streams from verification and curation.

Pioneering art technologies

Identity,
not image.

A human fingerprint is unforgeable not because of how it looks, but because of what it is. The same is true of an artwork. Our technology reads that irreducible physical identity.

The patent

US Patent 11,341,459 B2

Artentika is the sole holder of a United States patent in cultural-heritage technology: the multi-modal, biometric reading of cultural heritage artefacts. Its scope spans an entire media spectrum — paintings, sculpture, ceramics and textiles — because identity does not depend on the medium.

One-2-One©

The minutest discrepancy

Two photographs of one object, taken at different moments. One-2-One© resolves the smallest change between them — a hairline of new craquelure, a pinprick of loss, a substitution. Proactive value: it minimises conservation and legal expense before either becomes a crisis.

Material science

The physical substrate — what the work is made of, and how it has aged.

Image processing

Sub-perceptual structure: craquelure, strain fields, stroke geometry, palette.

Artificial intelligence

Learned representations compared mathematically — never pixel against pixel.

Quantified confidence

Every reading reports a statistical confidence, not a bare assertion or verdict.

Confidentiality is absolute. Your data is sealed to the blockchain and shared with no one.

1. Nature of our work

Artentika, a division of The Art Company AG ("ArtCo"), provides technical and forensic opinions. Every report expresses a probabilistic assessment with a stated statistical confidence. It is not a guarantee, certificate, or definitive determination of authenticity, authorship, attribution, date, or value.

2. Not a substitute

Our analysis is one element of due diligence. It does not replace provenance research, laboratory examination (e.g. pigment, dating, or imaging analysis), or the opinion of the relevant catalogue raisonné authority or attribution committee, and should not be relied upon in isolation.

3. Inherent uncertainty

Findings are statistical, may change in light of further evidence, and qualified experts may reasonably differ. No particular outcome is promised.

4. Client inputs

Our conclusions depend on the accuracy, completeness, and authenticity of the images, measurements, and information you supply. ArtCo is not responsible for results affected by inaccurate or incomplete materials.

5. No transactional advice

Our reports are not financial, investment, insurance, tax, or legal advice. Any decision to buy, sell, insure, or value an artwork remains your sole responsibility.

6. Limitation of liability

To the extent permitted by Swiss law, and save in cases of intent or gross negligence, ArtCo's total liability arising from any report is limited to the fees actually paid for that report. ArtCo is not liable for indirect or consequential loss, including lost profit, lost sale, or diminution in value.

7. Use and confidentiality

Reports are prepared for the client's own use and may not be published or reproduced without ArtCo's written consent. ArtCo treats all case content and the client identity as confidential.

8. Governing law

These terms and any report are governed by Swiss law; the exclusive place of jurisdiction is Zug, Switzerland.
