Abstract

A method, system, and apparatus for authenticating transactions and records is disclosed. A method for authenticating an information-based indicium includes receiving an article bearing a first identifier, wherein the first identifier substantially prevents a single user from accumulating multiple articles bearing the same first identifier, receiving a first digital certificate that is derived in part by encoding the first identifier, and comparing the first digital certificate and the first identifier to authenticate the information-based indicium.
