Abstract
A method of securely serializing product units to provide a trusted basis for the recording of transaction events reflecting distribution actions within and between supply chain participant vendors. The method involves receiving vendor data including vendor public data descriptive of a given product unit, generating a unique serial number to be securely associated with the given product unit, the unique serial number including a public serial number and a unique nonce, generating a cryptographic hash of the unique serial number and the vendor public data, generating a cryptographic signature of the cryptographic hash using a predetermined private key, and returning marking data including the public serial number.
