METHOD FOR THE INTEGRATION OF REAL-TIME DIGITAL TRACEABILITY, MARKING, AND BLOCKCHAIN-INDEXED UNAMBIGUOUS ORIGIN IDENTIFICATION

Resumen de: WO2026039881A1

The traceability method comprises the integration of traceability software, blockchain, and physical marking at origin using inert nanomarkers that are visible only when excited by a laser of a specific frequency. This integration ensures immutable and robust information in the process of tracing products and raw materials, as well as their production processes, since the nanomarker is not destroyed. In dielectric products/raw materials, integrity analysis equipment is used which, through readings of the reflection of the electromagnetic waves resulting from the interaction thereof with the material, determines its characteristic and unique dielectric profile - since each product has a dielectric constant for each wave frequency - resulting in a reflection-versus-frequency graph that is characteristic of the material. This profile is linked, by the user owner, in the traceability method, to the code corresponding to that product. The method is capable of managing the geolocation of each action on a product or raw material, generating unique and random two-dimensional alphanumeric codes, recording each action in the chain via smartphones or two-dimensional optical readers, linking these codes to tax documents and nanomarkers, as well as generating reports for decision-making.
