Authenticating serialized commodities

A system for authenticating a serialized commodity is presented. A fixed identification, serial number, and authentication code are received for a serialized commodity to be checked for authenticity. A reference table is searched for an entry that matches the received fixed identification. In response to finding an entry in the reference table that matches the received fixed identification, a fixed identification key is retrieved from the reference table that is associated with the received fixed identification. A recreated authentication code is generated for the serialized commodity using the retrieved fixed identification key, the received fixed identification, and the received serial number. Then, it is determined whether the recreated authentication code matches the received authentication code. In response to determining that the recreated authentication code does match the received authentication code, an authentication code match message is outputted to authenticate the serialized commodity.
