Abstract

The method and the device can be used for automated recording and reading of marking of securities, documents and products against falsification. The multi-stage protection (1-7) is generated simultaneously in independent generators (8-14), which generate forms and logic for marking (15-21), stored in devices (22) 8). Computer (29) merges all marking logics and by unit (30) controls a laser beam (31) which performs the marking on a carrier (32) automatically fed by means of a feeding plot (33) The reading device (34) feeds to unit (35) for comparing the marking logics (15) 1) with those already finished on the carrier (32), entering unit (36) for building into the valuable product. The result of the end control (37) by the reader (34) and any other information meaningful for the finished products are mixed in units for recording scrap bank notes (38-44) and in units (45-51) the end information is recorded, used in stages in the control against forfeiting. Digital camera (53) photographs part of the marking and records it. Reader (34), by it optical receiver (54) receiving the passing through light from (56) or reflected by (55), supplies the information to computer (57), which compares the marking with one or several of the stages in units (45-52). 3 claims, 4 figures
