Abstract
During manufacturing a unique encrypted authentication code is created for each product based upon device specific information relating to that product. The unique encrypted authentication code together with the device specific information is stored in a database, and a representation of the unique encrypted authentication code is stored on the product. To determine whether a product in question is authentic, the readable representation of the unique encrypted authentication code is read and sent to a server along with a request for product authentication. The server provides an indication of authenticity of the product in question based upon the unique encrypted authentication code received and the device specific information associated with that unique encrypted authentication code in the database.
