Identification documents with enhanced security
First Claim
1. An identification document, comprising:
- a document surface having information relating to the intended holder of the identification document provided thereon; and
a diffractive optically variable image device on the document surface, wherein the image device is based on at least a portion of the information on the document surface.

Abstract
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.
