Introducing xBiometrics: Downstream Security Feature for Precious Metal Products

aXedras is expanding its solutions offering with xBiometrics, a proxy-free security feature that authenticates physical products using images of their unique surface characteristics. This launch marks the next strategic step toward enabling end-to-end product integrity across the global precious metals value chain.

Through xBiometrics, aXedras bridges the gap between physical products and their digital twins within the Bullion Integrity Ledger™. This integration links physical authentication results directly to digital Integrity Certificates, creating a seamless connection between the physical and digital worlds.

Extending the Integrity Framework

The Bullion Integrity Ledger™ serves as the trusted digital platform for the global precious metals industry. With xBiometrics, aXedras extends its product offering to the physical dimension of the value chain, addressing the need for verifiable product authentication. Downstream security features have often operated separately from digital platforms. aXedras now unites these domains, allowing refiners, vaults, and dealers to link their physical authentication data to a secure digital framework where product identities remain consistent and verifiable throughout their lifecycle.

Why aXedras is Introducing a Security Feature

Offering a downstream security feature is a natural evolution of aXedras’ product offering. It supports our mission to provide market participants with a comprehensive integrity solution that verifies origin, documents production, and authenticates the final product.

By embedding proxy-free physical authentication into the platform, aXedras enables customers to:

• Authenticate bars and coins without physical marking, tagging, or alteration.

• Anchor product-level authentication data to Integrity Certificates within the Bullion Integrity Ledger™.

• Strengthen both internal security and external customer assurance.

About the Technology

To deliver xBiometrics, aXedras has partnered with Alitheon, a global leader in optical AI and no-touch serialization. xBiometrics leverages Alitheon’s LBMA-accredited FeaturePrint® technology to identify each bar or coin by analyzing its natural microscopic surface characteristics, similar to a human fingerprint.

Using a standard smartphone camera, xBiometrics captures an image of a product’s surface, enabling verification of the same item at any point in its lifecycle, without the need for applied markings, labels, or QR codes.

Complementary and Open by Design

aXedras, both as company and with its Bullion Integrity Ledger™, remains agnostic to all security features used in the precious metals industry. Companies that already apply existing security feature technologies can continue to register and manage their authentication data within the Bullion Integrity Ledger™.

Business Value for All Market Participants

By integrating xBiometrics into their operations, refiners, vaults, and dealers gain tangible benefits that enhance both efficiency and trust:

• Unified Product Identity: Link physical authentication data with digital Integrity Certificates for each bar or coin.

• Enhanced Customer Assurance: Provide buyers and trading partners with a verifiable, tamper-proof record of authenticity.

• Simplified Audits: Store and verify authentication results directly within the aXedras environment.

• Operational Efficiency: Reduce manual checks and document handling by connecting physical verification with existing digital workflows.

Combined with the Bullion Integrity Ledger™ and the aXedras Product Suites, xBiometrics empowers precious metal companies to streamline operations, strengthen compliance, and reinforce trust across their entire supply network.
