Abstract
A system and computerized method verify product custody along a product manufacturing chain. The method may include verifying a first machine-readable (MR) code for a product level N is valid by comparing the first MR code to a database of valid MR codes. Where the first MR code for the product level N is verified as valid, a second, valid MR code is generated for a next product level N+1 in the database of valid MR codes. In addition, the first MR code for the product level N in the database of valid MR codes is invalidated, so it cannot be used again. The second MR code is formed for use with the next product level N+1, e.g., by the downstream product manufacturer. Custody of product levels along a manufacturing chain can be verified and secured, avoiding bad actors from inserting and profiting from fake parts into the manufacturing chain.
