Abstract

In one aspect, the invention encompasses a method of information storage and retrieval. A first communication is stored as data in a database with an identifier code. At least a portion of the data corresponding to the first communication is sent to a printer which prints a portion of the first communication together with the identifier code on a substrate. The first communication printed on the substrate is changed to form a second communication which is different from the first communication. The second communication is scanned with a scanning machine which digitizes the second communication and also digitizes the identifier code that had been printed on the substrate. Information is extracted from the digitized identifier code with a processor. The processor is in data communication with the database and is configured to utilize the extracted information to retrieve the first communication from the database. The digitized second communication is compared with the data of the first communication to identify differences between the second communication and the first communication.
