Title: Leslie G. Butler and Secure Component Provenance
Introduction
Leslie G. Butler is an inventor associated with Baton Rouge, Louisiana. His work includes a patent addressing counterfeit detection and the secure tracking of manufactured components throughout their lifecycle.
Latest Patents
Butler’s listed patent is “Counterfeit Detection and Provenance with Grating Interferometry, Blockchain, and Smart Contracts.” The invention describes a method and apparatus for distinguishing authentic items from counterfeit or sabotaged components, including legacy additive-manufactured parts.
The method creates a trust anchor by modulating laser power to form selectively porous regions that encode digital information in a component using programmable invisible ink. X-ray grating interferometry reads both the encoded information and the component’s distinctive texture. A QR code and other anti-counterfeiting features can support efficient identification, while smart contracts connect X-ray radiography instruments with a blockchain database to establish provenance.
The approach is designed to have minimal impact on fabrication and to work with additive manufacturing, injection molding, and casting. It also aims to align with existing item-identification standards. Butler is listed as having 1 patent.
