Abstract

A method, system, and apparatus for authenticating transactions and records is disclosed. A nonce stamp is a physical article that is relatively difficult to copy illicitly, and that bears a "nonce" number. The "nonce" is a relatively unique identifier, in that it is chosen from a distribution such that any given user/customer is extremely unlikely to obtain two nonce stamps bearing the same nonce. The method includes: presenting a nonce stamp having a nonce number; presenting a numbered digital certificate derived securely from the nonce number; and authenticating the transaction by comparing the number on the digital certificate and the nonce number. The digital certificate is typically obtained by users/customers in exchange for the purchase price of a desired transaction. The apparatus is an information-based indicium including a nonce stamp, and a digital certificate including a number derived securely from the nonce. The system generates information-based transaction indicia, and typically includes one or more computers configured to receive as input a nonce number from a user; encrypt the nonce number; and provide to the user a digital certificate including the encrypted nonce number, so that the nonce and the digital certificate may be collectively presented as an information-based transaction indicium to authenticate a transaction.
