Apparatus and method for incorporating signature into electronic documents

Abstract

Embodiments relate to methods and apparatus for facilitating the protection from tampering of an electronic document to which an electronic signature is applied. In non-limiting examples, techniques may relate to the handling of document appearance data, dynamic signature biometric data, digital footprints data, pixel history data, and camera-acquired image data.

1 . A device for incorporating digital signature to within a document comprising:
 screen adapted to display the document;   signature means electronically communicating with said screen adapted to transfer an un-restorable digital signature to said document;   at least one reader adapted to provide digital signature and digitally sign the document;   interface port adapted to transfer the document from a computer to the device and transfer a signed document back to the computer;   
       whereby the document, which is generated on said computer, displayed on said screen is digitally signed and transferred with the embedded un-restorable digital signature to said computer. 
     
     
         2 . The device as claimed in  claim 1 , wherein said signature means is selected from a group of means such as electronic pen, biometric fingerprint, and other biometric data. 
     
     
         3 . The device as claimed in  claim 1 , wherein said reader is selected of a group of readers such as smart card readers or reader for private key container like dongle 
     
     
         4 . The device as claimed in  claim 1 , wherein said signature means is an electronic pen that can be based on technologies selected from a group of technologies such as light detection, sound or ultrasound detection. 
     
     
         5 . The device as claimed in  claim 1 , wherein said screen is an LCD screen. 
     
     
         6 . The device as claimed in  claim 1 , wherein screen is a touch screen. 
     
     
         7 . The device as claimed in  claim 1 , wherein the device further comprises control button adapted to allow interaction with the displayed document. 
     
     
         8 . The device as claimed in  claim 1 , wherein said screen is sized to an A4 document. 
     
     
         9 . The device as claimed in  claim 1 , wherein said at least one reader is incorporated within said device. 
     
     
         10 . The device as claimed in  claim 1 , wherein said smart card reader is separated of said device and is electronically communicating with the device. 
     
     
         11 . A method for incorporating digital signature to within a document comprising:
 generating the document to be signed on a computer;   transferring the document to a device for incorporating digital signature wherein said device comprising a screen, signature means, and at least one smart card reader;   displaying the document on said screen;   digitally signing the document through said at least one card readers;   applying a digital signature onto the document using said signature means;   transferring the digitally signed document to the computer;   sealing the document so as to prevent restoration of said digital document.
