Abstract

A multi-page security document has a first validation lens located in a transparent portion and corresponding to a first validation feature, and a second validation lens juxtaposed with the first validation lens as an adjacent layer in the transparent portion to the first validation lens and corresponding to a second validation feature.

Description

Background technique [0001] The present invention relates generally to security features for security documents, and more particularly to security documents having transparent portions with authentication lenses for revealing hidden information. [0002] Multi-page security documents can include hidden information in images. The hidden information can be revealed using a decoding lens placed over the hidden information. [0003] Often, people who verify security documents (eg, officials who process passengers through passport control) are very busy and may not have a lot of time to review all of the security features incorporated into the security document. Typically, verifiers primarily look at data pages with information identifying the document holder. Therefore, if a particular security feature is not available to a verifier no matter which page of the document is viewed, then this is a weakness in the document. [0004] From the foregoing, it is evident that there is a...
