Method for protecting the authenticity of an article from imitation and counte rfeit

摘要

A method for product authentication comprises attaching a bank note to a product label during the packaging process. The bank note serial number is encoded or encrypted to produce a code which is applied to the outer surface of the label. The code may be an alphanumerical code or a two dimensional code such as a barcode or QR code, and may be decoded or decrypted using a cryptographic key. The decoded or decrypted code may be compared with the serial number in order to authenticate the product. The verification process may utilise a manufacturers website or an app on a user device, and may take place online or offline.
