System for verifying of secure document










Image Number 18 for United States Patent #7757090.

A system is provided for verifying the validity status and/or authenticity information of a secure document. The secure document has user discernable information and a plurality of tags printed thereon. Each tag contains coded data encoding an identity of the document and a location of that tag on the document. The system has memory for recording a correspondence between the identity of the secure document and validity status and/or authenticity information relating to the secure document, a receiver for receiving data from a sensing device, and a processor for verifying the validity status and/or authenticity information of the secure document using the received data and the recorded correspondence. The data received from the sensing device identifies the document identity and a position of the sensing device relative to the document, and is generated by the sensing device sensing coded data contained in at least one tag.
