US Patent 8009873 Method and apparatus for providing identification

A method of providing identification of an entity includes maintaining a database of identification data specific to the appearance and condition of entities, providing a unique description for each entity enabling access to the entity's identification data in the database, providing identification means adapted for portage with the entity and containing the unique description and maintaining secondary databases containing the entity's identification data as acquired from prior encounters so that multiple comparisons can be made to assure that the individual bearing the identification means is the same individual to whom the identification means were issued.
