An authentication system and method for identifying the source of a marking formed from marking media is disclosed. A registration system preferably tags batches of marking media with taggant material and, for each batch, stores physical property information representing one or more physical properties of that batch. A source assignment system receives source identification information for each of a plurality of sources, stores the source identification information in a database and, for each source, links the source identification information with at least one batch. A source identification system comprises at least one instrument operable to provide physical property information for the media in a marking. The identification system also includes an analysis system operable to compare the physical property information for the media in the marking with the physical property information associated with batches, and to then determine whether there one or more matches of physical property information exist.
