The invention relates to the protection against the forging of credit cards, passports, identity certificates and other documents of strict accountability. The invention allows to resolve the problem of the state of protection against forgery of payment cards and documents while maintaining simplicity in the production of means of protection against forgery applied as protection of physical objects, particularly payment cards, passports, identity certificates and other types of proprietary information. The method of protection against the forging of physical objects consists in the inclusion in the matrix of the object to be protected or putting on its surface substances capable of, under the influence of electromagnetic radiation of from 0.1 to 10 nm wavelength (x-ray range) or of a from 10 to 400 nm wavelength (ultraviolet range), or a wavelength of from 400 nm to 780 nm (visible range), or a wavelength of from 780 nm to 59 um (infrared range), or under the influence of an electric field to luminesce (radiate) in the visible of infrared range; and the determination of the presence of coordinates, dimension, vending angle of radiating points is brought about with the aid of scanners, semiconductor matrices, etc. Furthermore, the digital graphic representation of the distribution of luminescing points (forming a pattern) is compared with a local or distant data base of patterns of protected objects established beforehand with the aim of consequent identification of protected objects. |
