Claims (5)

1. Способ контроля подлинности ценных бумаг, заключающийся в нанесении защитного кода, сканировании микроструктуры поверхности ценной бумаги, определении значения цифрового вектора-идентификатора, отличающийся тем, что микроструктуру или рисунок наносят на поверхность ценной бумаги по меньшей мере в двух местах с использованием заранее заданных значений векторов-идентификаторов, связанных числовым соотношением, которое сохраняют в тайне для дальнейшего статистического определения во время сканирования при определении истинности.1. A method of controlling the authenticity of securities, which consists in applying a security code, scanning the microstructure of the surface of a security, determining the value of a digital identifier vector, characterized in that the microstructure or pattern is applied to the surface of the security in at least two places using predetermined values identifier vectors associated with a numerical ratio, which is kept secret for further statistical determination during scanning when determining truth. 2. Способ по п. 1, отличающийся тем, что числовое соотношение между векторами-идентификаторами выбирают из диапазона 0,8 - 1,0. 2. The method according to p. 1, characterized in that the numerical ratio between the identifier vectors is selected from the range of 0.8 - 1.0. 3. Способ по пп.1 и 2, отличающийся тем, что микроструктуру или рисунок выполняют в виде прямых наклонных линий, а в качестве вектора-идентификатора используют угол наклона, и/или длину линий, и/или шаг линий. 3. The method according to claims 1 and 2, characterized in that the microstructure or pattern is made in the form of straight inclined lines, and as the identifier vector, the angle of inclination, and / or the length of the lines, and / or the pitch of the lines are used. 4. Способ по пп. 1 и 2, отличающийся тем, что микроструктуру или рисунок выполняют в виде окружностей, эллипсов или кругового узора. 4. The method according to PP. 1 and 2, characterized in that the microstructure or pattern is made in the form of circles, ellipses or a circular pattern. 5. Способ по пп.1 и 2, отличающийся тем, что в качестве микрорельефа используют искусственно исполненные, например, выдавливанием или тиснением лунки, а в качестве вектора-идентификатора используют любой из параметров лунок. 5. The method according to PP.1 and 2, characterized in that as a microrelief use artificially executed, for example, extruding or embossing holes, and as a vector identifier use any of the parameters of the holes.
