Abstract
A method for generating product authentication codes comprises allocating a lot identification value and a total lot size for an order of a plurality of product authentication codes, generating the plurality of product authentication codes based upon the lot identification value and the total lot size, and updating a counter table on an authentication server with the total lot size for the order of the authentication codes. A method for authenticating product codes comprises receiving a product code from a user of a product, decrypting the product code to obtain a sequence counter number unique to the product code and comparing the decrypted sequence counter number to a table of valid sequence counter number values to determine its authenticity. If the decrypted sequence counter number is authentic, it is added to an authentication table for future reference when operating to confirm a previous authentication of the sequence counter number.
