Abstract
Systems and methods for securing documents combine a physical document characteristic with variable information to form an authentication key. The key can be applied to the document along with the variable information. Subsequently, the document can be authenticated by re-reading the characteristic and variable information present on the document, forming another representation of the authentication key and comparing same to the authentication key carried by the document.
