摘要：
A method of generating an authentication code for a consumable includes assigning an identification number to the consumable; processing an input including at least the identification number, using a first algorithm, to generate a preliminary number different from the identification number; and compressing the preliminary number using a compression algorithm, different from the first algorithm, that utilizes the identification number to generate an authentication value for use in authenticating the consumable.
