Abstract

It is already known to print an updated and refreshed copy of an original physical document without leveraging on a computer with OCR technology and a text editor; generate a new document copy containing real time variable assignment values; synchronize back the electronic copy of the document, if any, with the last exploited values.

Sometimes it is useful to protect data in the original document, so that it cannot be accessed by anyone but just by authorized users. It may be also useful to digitally sign or authenticate the copy produced by the printer, e.g. when dealing with "official" documents in the public administration.

It is already known to print an updated and refreshed copy of an original physical document without leveraging on a computer with OCR technology and a text editor; generate a new document copy containing real time variable assignment values ; synchronize back the electronic copy of the document, if any, with the last exploited values.

On this basis here is proposed a method that allows to: - protect

 protect parts of the document to be copied from being read/copied from unauthorized users - allow only

only an authorized user

          authorized user to print an updated and refreshed copy of an original physical document without leveraging on a computer with OCR technology and a text editor
- allow only

only an authorized user

          authorized user to generate a new document copy containing real time variable assignment values
- produce a digitally signed/authenticated

authenticated copy of a physical document

The methods only needs an extension to the photocopier/printer logic, and a printer connected to internet. In this solution the part of the content to be copied is protected by means of encryption (the invention is not related to the field of encryption and it's not important to know e.g. what is the encryption algorithm or strength employed). Such parts cannot be copied and the copy machine will produce either a blank section or a warning message.

Access to the encrypted part is granted to user when a special section is added to the original document , e.g. a new area containing a bar code or a color code...
