System And Method For Identifying A Genuine Printed Document

Abstract

A system and method for verifying that a document is included in a document management system is disclosed. This system and method includes scanning of a scan track of a document, generating document data dependently upon the scanning, comparing the generated document data to stored document data, the stored document data generated dependently upon a prior scanning of the scan track of the document, and outputting an indication of the document being included in the document management system as determined by the comparing.

1 . A method for verifying that a document is included in a document management system, said method comprising:
 providing a document comprising a scan track having radio frequency readable information;   radio frequency scanning the scan track with a scanner head no greater than about 10 cm in its largest dimension;   generating document data dependently upon said radio frequency scanning;   comparing said generated document data to stored document data, said stored document data generated dependently upon a prior radio frequency scanning of the scan track; and   outputting an indication of the document being included in the document management system as determined by said comparing.   
     
     
         2 . The method of  claim 1 , further comprising:
 optically scanning the scan track;   generating optically scanned document data;   comparing said generated optically scanned document data to initial document data generated from at least one prior optical scanning of the scan track; and   outputting an indication of the document being optically authentic if said generated optically scanned document data is substantially identical to said initial document data as determined by said comparing.   
     
     
         3 . The method of  claim 2 , wherein said document is authenticated upon both said outputting an indication of the document being included in the system and said outputting an indication of the document being optically authentic. 
     
     
         4 . The method of  claim 1 , wherein said radio frequency scanning detects passive resonators positioned with the document. 
     
     
         5 . The method of  claim 4 , wherein said passive resonators are located within the scan track. 
     
     
         6 . The method of  claim 1 , wherein the scan track is positioned along one side of the document. 
     
     
         7 . The method of  claim 1 , wherein the scan track measures no greater than about 3 inches in width from said one said of the document. 
     
     
         8 . The method of  claim 1 , wherein the scan track measures no greater than about 1 inch in width. 
     
     
         9 . A method for verifying that a document is included in a document management system, said method comprising:
 providing a document comprising a scan track having scanner readable information;   optically scanning the scan track with a scanner head no greater than about 10 cm in its largest dimension;   generating document data dependently upon said optically scanning;   comparing said generated document data to stored document data, said stored document data generated dependently upon a prior optical scan of at least a portion of the document;   authenticating the document data using at least one radio frequency scan;   outputting an indication of the document being included in the document management system as determined by said comparing and said authenticating; and   said authenticating storing any variations in said generated document data as updated stored document data.   
     
     
         10 . The method of  claim 9 , wherein said optical scan is of a serial code located in the scan track of the document. 
     
     
         11 . The method of  claim 9 , wherein the scan track is positioned along one side of the document. 
     
     
         12 . The method of  claim 11 , wherein the scan track measures no greater than about 3 inches in width from said one side of the document. 
     
     
         13 . The method of  claim 9 , wherein the scan track measures no greater than about 1 inch in width. 
     
     
         14 . A system for verifying that a document is included in a document management system, said system comprising:
 a document comprising a scan track of radio frequency readable information;   a radio frequency document scanner comprising a radio frequency scanning head no greater than about 10 cm in its largest dimension;   a memory storing document verification data associated with the document;   a computing system operatively connected to said radio frequency scanner and said memory; and   computing system executable code accessible by the computing system and operative by the computing system to:   receive data from said radio frequency document scanner said data indicative of a radio frequency scan of the scan track of the document;   generate document data dependently upon the received radio frequency;   access the memory to recover the document verification data;   compare the generated document data to the recovered document verification data, the document verification data being previously generated dependently upon a prior radio frequency scanning of the scan track of the document; and   provide an output indicative of the document being included in the document management system if the generated document data is substantially identical to the recovered document verification data as determined by the compare.   
     
     
         15 . The system of  claim 14 , wherein said radio frequency document scanner is a desktop device. 
     
     
         16 . The system of  claim 14  wherein said scanning head is no greater than about 3 cm in it largest dimension. 
     
     
         17 . The system of  claim 14 , wherein said scan track is along one side of the document. 
     
     
         18 . The system of  claim 17  wherein said scan track measures no greater than about 3 inches from said one side of the document. 
     
     
         19 . The system of  claim 14 , wherein said scan track measures no greater than about 1 inch in width. 
     
     
         20 . The system of  claim 14 , further comprising an optical scanner, said optical scanner being operatively connected to said computing system such that said computing system executable code accessible by the computing system operates to receive data indicative of an optical scan of the scan track from the optical document scanner and said generated document data further depends on said optical scan data and said compare further includes a comparison with prior optical scanning of the scan track, wherein said providing an output indicates authenticity of the document if said comparison is substantially identical in both the optical scanning and the radio frequency scanning by the comparing. 
     
     
         21 . The system of  claim 14 , wherein said computing system executable code is resident on a computer readable medium.
