Certified Pre-Owned Authentication That Cannot Be Faked

Give buyers verifiable proof of an item's identity, history, and condition — anchored to the object itself, not to paperwork.

Every item verified, every time. Fast, consistent,
and impossible to fake.

Talk to Us About CPO Authentication

The secondary market for luxury goods, watches, handbags, electronics, and high-value vehicles is worth hundreds of billions of dollars globally — and it runs on trust that is increasingly hard to establish.

Serial numbers can be ground off and re-stamped. Certificates of authenticity can be scanned, duplicated, or transferred to a different item entirely.

A buyer purchasing a certified pre-owned product today has no way to independently confirm that the certification is real, that the item in their hands is the same one that was inspected, or that its history has not been altered. DUST Identity solves this by binding an unclonable physical identity directly to the object at the point of certification — so the proof travels with the product, permanently.

Why existing CPO programs have a trust problem

Certificates can be separated from the object

A certificate of authenticity describes an item but is not attached to it. Once a certified item changes hands, the certificate and the product can be separated, swapped, or reassigned. A fraudster selling a counterfeit can simply pair it with a genuine certificate purchased separately.

Serial numbers are not enough

Serial numbers can be removed, re-engraved, or duplicated. Even laser-etched numbers on watch cases or stamped numbers on luxury bags have been successfully replicated. A number that can be copied is not proof of identity.

Inspection records live in databases, not on the object

Most CPO programs store inspection history in internal systems. When an item is resold privately or through a third-party platform, that history becomes inaccessible or unverifiable. Buyers are left taking the seller's word for it.

Fraud scales faster than manual verification

As the resale market grows, the volume of items moving through secondary channels makes individual manual verification impractical. Brands and CPO program operators cannot inspect every item at every transaction point.

What DUST enables for certified pre-owned programs

A physical identity that stays with the object

At the point of certification, DUST applies an engineered diamond-dust marker directly to the item. This marker is invisible, unclonable, and permanently bound to the surface. It cannot be removed without destroying it and cannot be transferred to another object.

Instant verification at any point in the lifecycle

At any future transaction — resale, insurance, consignment, or authentication — the item can be scanned and its identity verified against its digital record in seconds. No manual review. No reliance on documentation that may or may not be present.

A digital record that grows over time

Every scan event, ownership transfer, inspection, and service record is logged against the object's unique identity. This creates a verified history that adds value to the item at every resale — buyers can see exactly what happened to the object, when, and where.

Compatible with existing certification workflows

DUST integrates into existing CPO program processes. The marker is applied during the standard inspection step and requires no changes to how items are received, assessed, or documented. Verification uses a handheld scanner that works with existing devices.

Where certified pre-owned authentication matters most:

- Luxury watches and jewelry
    High-value timepieces and fine jewelry are among the most frequently counterfeited categories in the secondary market.
     A DUST marker applied during manufacture or first certification travels with the piece through every auction, private sale, and service event.

- Luxury handbags and accessories
    The market for pre-owned luxury fashion is growing rapidly, and so is the sophistication of counterfeits. DUST gives resale platforms and brand-    operated CPO programs a verifiable proof layer that documentation alone cannot provide.

- High-value - electronics and devices
    Refurbished and certified pre-owned consumer electronics carry significant fraud risk, particularly in business-to-business channels. DUST     enables device-level identity that survives factory resets, firmware changes, and physical repairs.

- Collectibles and memorabilia
   Game-used sports items, signed collectibles, and limited-edition products are especially vulnerable to provenance fraud. DUST ties each item     to its authenticated history from the moment of certification forward.
