Currently, direct financial losses due to counterfeit banknotes, credit cards and securities make up a significant amount of that is due to the fact that the current level of computational, analytical and copying equipment allows you to play at a relatively low cost virtually any security in any quantity.

Especially this is a major problem in the case of bulk products, such as money when the cost of production and protection against forgery should be minimal. In addition, the label should quickly and easily be detected.

There are various methods of protection money and securities against forgery. A significant portion of them are methods of protection with the use of metal labels, and the label may be formed by direct deposition of material, usually in the form of paint, security, and application products, made of metal, for example, the strips on paper.

There is a method of protection of banknotes, in which the bill applied a special image with magnetic ink. The registration label is a magnetic detector (GB, N 2079506, CL G 07 D 7/00, 1982). However, this method acesse long-term operation of banknotes.

There is also known a method of protection securities fraud, which consists in pressing a paper strip of magnetic material. The definition of authenticity securities is also using a magnetic detector that registers the intensity of the magnetic field (ER, N 0057520, CL G 07 D 7/00, 1982). However, this method is not reliable, because it does not exclude the possibility of forgery, because the manufacturer (fake) band of magnetic material presents no technical difficulties.

You know the securing paper products in the form of a metallic filament (DE, N 2912712, CL G 07 D 7/00, 1979). However, the label in the form of strands from the available material may not provide enough protection.

An object of the invention is to increase the degree of protection against forgery of securities and documents while maintaining ease of fabrication tools for protection against forgery, used as a label in the manufacture of valuable papers and documents, in particular banknotes.

The problem is solved in that in the method of protection against forgery of securities and documents, including a connection with the material of the protected object labels in the form of strips or strands with the possibility of a counter is the control of the presence of the label is performed by the method of nuclear magnetic resonance.

Reliable protection in this case is provided by using as the label of the product from a unique material, mastering the production of which requires a level of work that is available only to the state or a major Bank. The cost labels directly on a separate bill insignificant due to the fact that in order to ensure error-free identification label requires very small amounts of material for application of the label.

The selection of isotopes of osmium-187 is a complex, expensive and lengthy process, as well as other isotopes of heavy elements, such as tungsten, platinum, iridium, etc. But it osmium isotope allows to realize quite fast, cheap and reliable method of registration authentication on specific nuclear magnetic properties of isotopes of osmium-187.

In the particular case of the process connection of the strips or strands of material of the protected object is realized by fixing on the surface of the material.

In another particular case, the connection strips or strands of material of the protected subject matter carried out by pressing it into the material.

In another particular case, the connection strips or strands of material protected the imposition of the strips or strands of material of the protected object is realized by bonding strips or threads between at least two layers of a multilayer material.

To increase the reliability of protection when connecting strips or strands of material of the protected object give her any configuration and establishes connection to any area and any area of the material.

The problem is solved also by the fact that the means of protection against forgery of securities and documents executed in the form of strips or strands containing osmium-187 whether its connection.

Most preferred is the presence of osmium-187 in the band or thread in an amount of 5 g or more in one valuable paper or document, as the number of < 5 µg becomes difficult to detect the presence of an isotope of osmium-187.

The most preferable from the viewpoint of the convenience of detection reliability of protection against forgery is an introduction to the material of the protected object or drawing on it strips or filaments, which is carried out in a chemical compound of osmium-187, providing a permanent magnetic orientation of the atoms.

In particular, chemical compound, providing a permanent magnetic orientation of the atoms of osmium-187 is FeOs when the content of osmium-187 is FeOs when the content of osmium in the number 1-9 mol. The content of osmium-187 is selected from plusem permanent magnetic orientation of the atoms of osmium-187, is FeBO3Os.

In the particular case of the product in the form of a strip made of two layers of polymeric material and located between the layer containing the osmium-187 or its connection.

In another particular case, the product is made in the form of strands of polymer material containing particles containing osmium-187 or its connection.

In another particular case, the product is made in the form of yarn consisting of a core made of a material containing osmium-187 or its compound, and a polymeric shell.

In particular, as a polymer material, in all cases, there may be used polyethylene, or other materials based on polyethylene, or polyester, or polyester.

In Fig. 1 shows the variants of the method of protection against forgery of securities and documents: a) a strip containing the osmium-187 or the connection is fixed on the surface of the securities; b) the strip is pressed into paper; paper stitched stripe.

In Fig. 2 shows a means for protection against forgery, made in the form of strips: (a) containing osmium-187 or connection (solid); (b) containing osmium-187 or its connection (made in the form of plots).

On FD osmium-187 or its connection; b) the thread with a core material containing osmium-187 or its connection.

You can use different technological processes for the implementation of the connection strips or filaments containing an isotope of osmium-187 or its connection with the material of the protected object. The most simple is the fastening strip (thread) 1 on the surface of the material 2, for example, by gluing or securing strip (thread) 1 2 material of the protected object. Option connection with the material of the protected object, for example, securities, is the firmware stripe (thread) 1 2 material (paper). When using laminated paper possible bonding strip (thread) 1 between two or more layers of paper.

To improve the reliability of the security strip or thread connected to the material of the protected object may have a complex geometric shape, thereby creating the predetermined pattern of the label while the label may occupy a large area on the protected material until the entire area of the protected paper in case of its special value. When a smaller value of securities is recommended to simplify the illustration of the label, thereby adesivi the cost of manufacturing securities. For example, when isgur CLASS="ptx2">

For detection is used are known from the prior art NMR spectrometer, in which the orientation of the magnetic fields of the nuclei investigated material used superconducting magnets that create magnetic fields up to 20 Tesla. Superconducting magnets are the main part of the cost of the spectrometer.

The introduction of isotopes of osmium-187 in the form of compounds of osmium-187 with a ferromagnetic substance allows to use the internal magnetic fields of the atoms of up to 500 T and more, because the interaction with the magnetic fields of the ferromagnetic magnetic fields of the atoms follow. This allows you to receive the signal of NMR (nuclear magnetic resonance), i.e., the effect of selective absorption of radiation of a certain radio frequency, without the application of strong external magnetic fields. Also favorable characteristic of osmium-187 is the fact that the nucleus has spin 1/2, and hence no electric quadrupole moment that allows you to get rid of electrical disturbances.

The simplest connection, allowing you to Orient the magnetic field of the nuclei of osmium-187 is FeOs with the contents of the OS from 1 to 9 mol Connection keeps ferromagnetic properties.

Special material that allows veleterzni isotope label, is FeBO3Os. High gain signal in this case is associated with extremely low field magnetic anisotropy connection FeBO3Os.

Detection in the case of use as the label of osmium compounds with ferromagnetic substance is also known methods. When the overlay generated by the instrument (detector) radio-frequency pulse /2 (out of phase with the magnetic moments of the nuclei) the spins of the nuclei "crumble". When the next pulse (in-phase) the spins of the nuclei are returned simultaneously to the main oriented state, which allows you to register so-called spin echo.

Detection is performed at the operation of the device only on the kernel of osmium-187 with the resonant frequency of 107.5 MHz.

Means for protection against forgery used in this method for forming a label of a given configuration, made in the form of device that represents a narrow long strip or thread, later on, during the implementation of the protection of securities or instruments, cut into pieces of a given length.

In one of the possible ways the band is made from a layer 3 containing osmium-187 or its connection placed between layers 4 of th 3 represents a pre-rolled with a roller to a thickness of approximately 10-30 μm strip of material of a width of from 0.4 to 1.2 mm, which then hot glued method between the two layers 4 of the polymer. Between layers of polymer can be pasted and some parts of the material containing osmium-187 or its compound, i.e., the strip of material may be intermittent.

In another embodiment, the thread contains a polymer base 5, which is divided particles of 6 material containing an isotope of osmium-187 or its connection. This thread can be made using the extruder with the introduction of the molten polyethylene metered quantity of powder material containing osmium-187 or its connection. A thread may also be enclosed in a polymer shell 7 of the 8 core material. Making such threads are also known methods.

Industrial applicability. Modern technologies allow to obtain the osmium-187 in required to implement the process quantities, for example, from registergui poor and ultrametric ores, or from the poor and ultrametric waste process solutions. A small number of isotope required for the manufacture of strips or threads, used as a label directly into one bill or security, and ease of manufacturing technology stand large scale, for example, in the production of banknotes.

NMR is a method of detecting the authenticity of the label ensures high accuracy and reliability of the method, it does not require complex and expensive equipment. Authentication can be carried out by the unit weight not exceeding 10 kg.
