摘要:
A method for performing optical character recognition (OCR) on an image of a document including text includes embedding a physical manifestation of digital information associated with the text on the document. When the document is scanned with a scanning device, the digital information and a digital text file are produced. The digital text file is proofed using the digital information.
摘要:
A printer that prints encrypted information in a document can be the key authority for that document. A document containing encrypted information and a source reference can be printed by a printer associated with a key module. The key module contains the key for decrypting the information. A scanner scanning the document obtains the source reference and the encrypted information. The scanner can use the source reference to send a key request to the printer and the printer can respond with the appropriate key. A decryption module associated with the scanner can use the key to decrypt the information. The decrypted information can be incorporated into a second document that can be electronically stored or printed.
