Method and system for certifying product authenticity using physical feature information including digitized surface fingerprint and blockchain

摘要

Disclosed is a method and system for certifying product authenticity using physical feature information including digitized surface fingerprint and blockchain, each of which manages certification information, packaged by binding together unique product information and physical feature information including surface feature of a product as a unique product feature, based on a distributed ledger of a blockchain to reliably determine whether the product is authentic or not in various ways. The authenticity certification information is packaged as a unique product feature by binding a serial number of the product for which the certification information is generated, together with physical feature information of the product, including image-based surface fingerprint. The authenticity certification information is stored in the blockchain. Determination on authenticity is made by comparing the identification information and the physical feature information with the authenticity certification information stored in the blockchain.
