SYSTEM AND METHOD FOR PRODUCT REGISTRATION

摘要

A system and method for controlling a production process for producing a product is provided in which overproduction may be inhibited by introducing a separation of duties within a production process Typically a producer will contract out the various stages of a production process to multiple contractors. In general, separation of duties involves purposefully separating production stages, for silicon chips or other products, so that the end product has been handled or "touched", by each subcontractor, in order for the end product to be fully functional This is achieved by way of a module having a mathematical transform for intercepting and transforming data flow in the product The mathematical transform requiring a key to be operable, the product requiring successful operation of the mathematical transform to be operable and the key is divided into a plurality of portions of sensitive data which are added during production of the product in a plurality of stages
