BG61241B1 - Method and device for recording and reading of multistage multi-media protection - Google Patents

Abstract

The method and the device are used for protection markings against forfeiting of securities. Forfeiting of protected securities is practically impossible due to the availability of a large number of combinations between marking signs which are independent from each other. The method includes generation from independent generators (8-14) of at least two input signals, mixing in a control computer (29) and applying on a protection carrier built-in in the security (33). The labelled security (33) is checked for validity by comparing at least two of the recorded perameters and it is removed in case of any discrepancy. The device consists of at least two degrees of protection (1-7) each containing one generator (8-14) connected by its own marking. Generators (8-14) are connected to a control computer (29) connected to a laser recorder after which a distribution unit (36) is fitted connected to units for end recording (45-51) on the multimedia carriers.

Description

The invention relates to a method and devices for recording and reading multilevel multimedia anti-counterfeiting, applicable in the production and control of money, documents, securities and products in doubt of their originality.

BACKGROUND OF THE INVENTION

Methods and devices for recording and controlling marking security of securities and products against counterfeiting by application of: watermarks, UV-visible inks or other light source, micro-barcodes, one-step metal thread, micro-kinograms, excise labels are known and others whose control is by comparison with the naked or naked eye.

The general disadvantages of the known methods and devices are the following: they do not offer multi-level protection in the same marking with high resolution and self-contained degrees of protection; security logics are easy to decipher and markings are easily falsified because of the multilevel security, the low number of cipher combinations and the lack of protection against corruption or negligence; do not offer removable selective media with information of one, two, or other different levels and markings with an automated reading and location control device.

SUMMARY OF THE INVENTION

The object of the invention is to provide a method and devices for recording and reading of multilevel multimedia security, marking securities and counterfeiting products, which achieve multilevel security in the same or several markers with higher resolution and density with generation and the segregation of each security level / level of protection from individual machines and persons with sufficient volume storage for mobile devices with automated controls to virtually eliminate corruption or negligence OTA with single-stage defeat.

The task is solved by a method and devices for recording and reading multilevel markings (ciphers), which are generated by parallel, independently operating and recording cipher systems. The information from the systems is mixed by a computer when controlling the laser beam that affixes the markings. All grades (codes) are recorded on a separate medium, which after the final control of the marking and the security, document or others. is updated and linked to other information / qualities or numbers and re-recorded on a single or group of grade levels / marking. The latter medium is used in a computer which, by means of a reader, compares the marking of a certain degree (level) with the original form and cipher for that level, and the controller authorized for the respective degree receives information whether the marking is false. Other logic levels or levels remain undisclosed when logic or falsification is attempted.

The invention is illustrated by the accompanying drawings, of which:

Figure 1 is a block diagram of 7 stages of protection;

Figure 2 is an enlarged sketch of 7-step banknote marking;

EXAMPLES FOR THE IMPLEMENTATION OF THE INVENTION

The seven levels of protection 1-7 consist of parallel working and independent generators 8-14 of random numbers, logic or ciphers that define different for each level of markings 15-21. The generated levels are recorded on multimedia media 22-28, and the current levels are fed to a computer 29, which mixes them and controls the deflection system 30 of the laser beam 31, which records on the laser beam 31, which records on the media 32 all stages simultaneously. The computer 29 automatically controls the feeder board 33 and adjusts the intensity, focus, and other beam parameters by feedback from the automatic reader 34 and the auxiliary comparator 35, which compares the read record with that of 15-21.

The finished multi-stage marking on the media is integrated into the manufacturing process of the article 36, and in its final control 37 parameters determined by the manufacturer and the controller of the suitable articles are supplemented by the reader 34 to the databases for each grade 22-28. Systems 38-44 report a marriage, programmed binding of certain parameters of a valuable document or product with definite degree markings, and in 45-51 respectively, the final recording on the multimedia medium of each degree of protection is made.

An exemplary solution for multilevel multimedia security is shown in the sketch of FIG. A six-micron microlone support 32 is supported with a 0.00006 mm sandwich layer of three equal components silicon nitride, aluminum nitride, silicon nitride, laser beam 31, which reads the BNB markings 1521 bearing the logic of levels 8-14. recorded on optical media. Marks 15-21 can be visible to the naked eye or other images or invisible with resolution - up to and above 3000 lines per millimeter. For example, for markings 16-21 with intentionally enlarged in figure 2 logic. Each of the markings in levels 15-21 is recorded on a separate optical disk 45-51 for the controllers after 34 has read logic 8-14 and reconciles it with the fit banknote number of 37.

The results of the final control 37, from the reader and other relevant product-relevant information, are mixed in 38-44 and in the 45-51 the final information used in degrees against counterfeiting is recorded. The reader 34, through the optical receiver 52, receiving the passing light of 54 or reflected by 53, transmits the information to a computer 55, which compares the marking with one or more of the steps in 45-51.

APPLICATION OF THE INVENTION

The optical information recording and reading device works as follows: The seven degrees of protection are generated by seven parallel-working and independent random number generators 8-14, which assign different degrees to each mark 15 - 21. The degrees generated are they are recorded on media 22-28 and the current ones are fed to a control computer 29 which mixes them and controls the deflection system 30 of the laser 31. The banknote 32 containing the built-in security carrier is mounted on a feeding table 33 which is commanded. two from the control computer 29. The laser beam 31 records on the security host all protection levels 1-7 at a time. The control computer 29 adjusts the intensity, focus, and other parameters of the laser beam 31 through feedback provided by the first automatic reader 34 'and the auxiliary comparator 35, which compares the read record with that of markings 15-21. In the terminal control unit 37, the parameters of the fit banknotes (currency type, banknote denomination, numbering) defined by the manufacturer and the controller are supplemented to the media 22 28 by the second automatic reader 34 ”. Scrapped banknote reporting units 38 - 44 count for marriage, and in the end recording units on multimedia record 45-51, a security mark is updated individually for each security level.
