Trusted hardcopy document

摘要

A trusted hardcopy document is generated using a two-part confirmation number including a private part and a public part. A public part of the confirmation number is received at a first party creating the trusted hardcopy document. The private part of the confirmation number is sent to an owner of the trusted hardcopy document by a trusted party and is not sent to the first party creating the trusted hardcopy document. A human-readable form and a machine readable form of the public part of the confirmation number are printed on the trusted hardcopy document.
