Abstract: A device which collects the pixel information generated during printing or scanning of a document, and transforms this sequential information into a code A which has a one-to-one relationship to the sequential pixel information, and which device computes from this code A a hashcode H which meets the requirements of a digital signature, and which device then feeds the digital information needed to print the hashcode H to the printer, in a pixel format, or feeds the same hashcode H to the digital media storage device, in both cases in a part of the document page which is digitally stored or printed, a method of use of the said device in encoding a document to form a hashcode H in pixel form.

Abstract: A process for integrity check of lots of individual package units which comprises combining at least one RFID tag and a container which contains a large number of individual package units wherein each of the individual package units is marked with a marking code, the information of these codes of all individual package units is combined, and a hash code is generated based on the combined information of all marking codes of all individual package units, which combined hash code is stored in an RFID tag which is affixed to the container, this combined hash code together with the individual hash codes for the individual package units being stored in the data base of the SENDER site where the container is packed and sealed, the individual hash codes then being transmitted to the RECIPIENT of the said container, the information collected from the RFID tag being compared to the combined hash code which is calculated at the RECIPIENT site from the information received by the SENDER of the said container including al

Abstract: A method of archiving documents by duplicating data by means of an acquisition and reproduction circuit connected to a personal computer, the circuit responding to a current document image output signal from a running printer. The information is stored in the computer's memory as a binary identical image of the document to be printed. The image is then archived for permanent storage.

Abstract: The invention concerns a documentarchiving method which does not use a scanner. To this end, a recording and reproduction circuit controls the memory of a personal computer by means of the last printed imageproducing output signals of a running printer and files in the memory an identical binary image of the document to be printed. This image is recorded on a nonerasable data carrier (e.g. a CDROM) for permanent storage.
