1. A method of providing authentication information for an authentic substrate and authentic documentation associated with the authentic substrate, comprising the steps of:
a. providing at least one identification code associated with the authentic substrate;
b. providing at least one identification code associated with the associated, authentic documentation;
c. providing a taggant key on the associated, authentic documentation, said taggant key providing spectral characteristics responsive to illumination by at least one light source, wherein a spectral signature is encoded in the spectral characteristics of the taggant key;
d. storing a record in a database, wherein the record stores authentication attributes of the authentic substrate and the associated, authentic documentation in fields comprising the identification code associated with the authentic substrate, the identification code associated with the associated, authentic documentation, and the taggant key provided on the associated, authentic documentation; and
e. providing functionality that allows information harvested from an evaluated substrate and an evaluated document to be compared to the authentication attributes stored in the fields of the record in order to determine that the evaluated substrate is a match for both the authentication attributes of the authentic substrate and the associated, authentic documentation, and that the evaluated document is a match for both the authentication attributes of the authentic documentation and the associated, authentic substrate.
