The invention described herein utilizes a universally known and accepted
unique item that is independently identifiable and valuable so as to be
constituted for difficulty of counterfeiting as an authenticator item.
The identity of this item is included in an authorization calculation
which can only be accomplished by an authorizing issuing authority. In a
preferred embodiment of the invention, the authenticator is a serial
numbered item such as a currency bill or note. The document may be
created in a decentralized fashion using ordinary plain paper and the
document may even take electronic or other forms. The issuing authority
must have the critical or important details of the document and must
authorize the creation of the document before it can be created. Further
the document's authenticity may be verified without communication back to
the issuing authority.The invention allows the creation of valuable
negotiable business documents at locations throughout the world and the
creation may be done by any of an issuing authority, an agent of the
issuing authority, a bearer and even the buyer. The invention described
allows cancellation to prevent negotiation of an electronic document
regardless of how many copies are extant in computers or other form
merely by defacing or destroying the associated authenticator.
