Turn every bar into its own unforgeable certificate.
AI-powered surface fingerprinting for gold and silver bullion. No ink, no tags, no physical tampering — just a microscopic signature that can't be faked, verified anywhere in under 3 seconds.
Counterfeiting and compliance gaps are costing the precious metals industry millions.
Counterfeit bullion is getting more sophisticated by the year.
Once a bar leaves the refinery, proving its origin gets harder, not easier.
Chain-of-custody records are often fragmented or opaque.
Regulatory and compliance requirements keep expanding across jurisdictions.
A counterfeit bar can be visually identical to the real thing, down to the serial number. Traditional countermeasures — special inks, physical tags — are visible, tamperable, and slow down production.
Gold Fingerprint turns verification from a manual, trust-based process into something instant and self-service — for refiners, dealers and owners alike.
Every bar is fingerprinted the moment it's cast, closing the window where forged or substituted bars enter the supply chain undetected.
No lab analysis, no waiting on a refiner to confirm origin — a single photo is enough to confirm a bar's identity on the spot.
Provenance stops being a claim on a certificate and becomes something any owner, dealer or buyer can independently verify.
Chain-of-custody is captured as a byproduct of verification, not a separate paperwork exercise your team has to maintain.
Gold Fingerprint reads the surface a bar already has — no tagging, etching or additional manufacturing step required.
Refiners and dealers stake their name on every bar that carries it. Gold Fingerprint gives that claim something to stand on.
As each gold or silver bar is cast, a high-resolution imaging pipeline captures its unique surface topography — microscopic detail as individual as a fingerprint, and just as hard to fake.
Deep convolutional neural networks extract intrinsic, microscopic features that stay invariant to scratches, dust or handling, encoding them into a high-dimensional digital fingerprint unique to that bar.
A consumer mobile app captures a new image of the bar, cleans it and generates a query hash. The hash is matched against the fingerprint repository — authenticity confirmed in seconds.
Every fingerprint is cryptographically linked to the refinery's custody records, giving owners a transparent, auditable history of their asset from refinery to their hands.
Gold Fingerprint's models are trained specifically on precious metal surface topography — not a general-purpose vision system repurposed for a new use case.
Authentication isn't locked behind the refinery that minted the bar. Any dealer, vault or owner can confirm authenticity from a mobile app.
The fingerprint and its custody record persist across every handoff, so trust doesn't reset each time the bar changes hands.
Precision optical capture for detailed surface data acquisition.
Automated, hierarchical feature extraction robust to variations in illumination and orientation.
High-dimensional representations capturing the unique intrinsic characteristics of each bar.
Discriminative embeddings and distance metrics tuned for accurate matching.
Efficient retrieval of similar fingerprints from a large database.
Ensures the integrity and immutability of the link between a fingerprint and its custody records.
A high-resolution image of the bar's surface topography at the moment it's cast — microscopic detail that's as unique to that bar as a fingerprint is to a person, and just as hard to replicate.
No. Capture happens with an imaging step added at your existing casting line — there's no new tagging, etching or material added to the bar itself.
No. The fingerprint is derived from the bar's own physical surface, not an applied marker, so it can't be lifted, duplicated or moved to a different bar.
Anyone with the consumer mobile app — a dealer, a vault operator, or the end owner. Verification isn't limited to the refinery that cast the bar.
Wherever you need it — we support AWS, GCP, Azure, or your approved private cloud. The original image, processed surface map, and encrypted fingerprint hash all stay under your infrastructure preferences, encrypted in transit and at rest, with infrastructure aligned to ISO 27001, SOC 2, and relevant industry standards.
Every signature goes through a two-tier verification process before authentication is confirmed. In extensive testing, the system has rejected 100% of counterfeits presented to it.
Yes — secure APIs connect directly to refinery custody systems, ERP platforms, and regulatory reporting tools.
Yes — gold, silver, any shape or size, with no physical modification required.
It complements them. Stamps and serials can be forged or reused; the surface fingerprint can't, so it acts as the layer of proof those markings can't provide on their own.
