Abstract
Manufactured goods are marked or labelled with a secure unique identifier. A central checking centre allows users to verify the authenticity of a particular good such as a cigarette pack or carton via any convenient interface such as the internet or a cell phone. A system of secret sharing allows secure authentication of each item and prevents code breaking or misuse.
