Steganography of vector graphics and typography in infrared security printing

The paper elaborates on linear graphics and typographic elements in the function of hiding information in security printing. Hidden information is introduced with the goal to protect the originality of the produced graphic designs so their counterfeiting would be impossible. Those graphic designs are made with programmed linear and typographical elements that have different response in the part of the spectrum visible to the human eye, and in the near infrared part of the spectrum observed with instruments. In order to have different response in the said spectrum parts, in each of the two designs colors are separated in two different ways. In order to achieve unique results, complex algorithms and random numbers are used for color separation. Unique graphic designs have been obtained by merging design and security against counterfeiting.
