An identification document having enhanced security and replication
deterrence, while providing a simple low cost solution to other
verification and authentication technologies. In one implementation, the
document is provided with a multi-layer, multi-axis diffractive optical
variable image device (DOVID) that is based on specific data or
information on the document. The result is that the DOVID is directly
tied to data or information that is specific to the document. This DOVID
security feature is verifiable by the human eye so that no high levels of
technology are necessary to verify authenticity. In addition, this DOVID
security feature has enhanced tamper detection.
