Abstract
The invention relates to the field of the protection of securities from counterfeit and is intended for determining, using equipment, the authenticity of printed articles being protected such as all types of securities. A security has a marking which comprises at least one inorganic compound with a crystalline structure, which inorganic compound is alloyed with ions of rare earth elements and has the property of selective reaction with radiation in the optical spectral range, wherein in the event that said inorganic compound is exposed to radiation in a set band of the optical spectrum, the radiation of the compound only in this band of the spectrum has an excess above thermal radiation with a finite length of 10-10 seconds or more. The proposed invention makes it possible to increase the degree of protection of a security.
Description
Technical field
The present invention relates to protection secure file (security document) to avoid forging; and the instrument checking of the authenticity for shielded print product (such as, banknote (banknote) and blank security list and tax label and stamp).
Background technology
For verifying that a kind of method the most effectively and in technically feasible method of the authenticity of the banknote with hiding security feature is the emission characteristics again of the compound that assessment comprises in safety notice composition or in the substrate of banknote and secure file.The ability of the higher level of security the method provides high-performance, causing due to the chance creating hiding security element and the checking by non-contact method.
Sort in the checking of (sorting) and its authenticity in the high speed of banknote, these advantages result in the widespread use of the security feature hidden of the use of the non-linear optical property based on various mineral compound.
The detectability that the reliability of scanning and people use the difficulty of conventional research method (being specially spectrum and luminesceence analysis method) for the major requirement only for the such machine-readable hiding feature of being undertaken verifying by note validating equipment.
Conventional secure file comprises mark, namely based on the authentication feature (WO 81/03507 A1 1981) of transparent (crystalline) structure of ion with rare earth metal.To launch and light activated absorption occurs in as seen and near infrared (IR) region of spectrum, and in described nearly IR region, there is the regional transmission that wherein compound only launches.Described document also discloses a kind of method of the authenticity for authenticating security documents, and wherein, excitation-emission and induction transmitting are divided into multiple passages with specific bandwidth; Measure described induction launch and the gained array of measured value is used as authenticity standard.Authenticity analysis only considers the intensity of spectral band (band) according to the whole set of response parameter.
Because the individual spectral of launching based on the induction of the dead matter of rare earth element is not its exclusive feature, so make problem in this way be its deficient powers of resistance to counterfeit (forgery); These spectrum are well studied and can be determined by the mode of the arrangement of the energy level in rare earth, activator.Therefore, there is similar activator, even there is the counterfeit of different chemical compositions can present similar or identical induced emission in specific spectral band.
WO 81/03510 A1 1981 describes a kind of safety paper with the authentication feature formed by luminescent substance, and (described luminescent substance has the luminescent spectrum only in the invisible part of spectrum, and to be provided by invisible light excite) and the method for invisible checking of authenticity of safety paper, wherein, described safety paper is exposed to by light source exciting with the invisible part of spectrum, and can analyzes by pick-up unit the light-emitting line launched in the invisible part of described spectrum based on wavelength or relaxation time.
This method, based on the use according to the luminophor launched from the Stokes' law (Stokes'law) that other technical field is known, therefore, can not solve the problem improving and make secure file avoid the level of protection of forging.
WO 2007/003531 A1,11.01.2007 describe the secure file with the security feature based on luminescent material treating to use in security document, this secure file comprises the host lattice (host lattice) be made up of the rare-earth oxide sulfate of the ion doping with at least two types.This luminescent material presents anti-Stokes luminescence and the luminescence according to Stokes' law.This luminescent material comprises two kinds of compositions (constituent): with different ratios doped with the yttrium oxysulfide of ytterbium/holmium and the yttrium oxysulfide doped with ytterbium/erbium.
On the one hand, the shortcoming of this method comprises the known luminescent substance of use as security feature.Adulterator may can obtain described known luminescent substance, and in addition, fully knows and have studied the combination of the characteristic of these luminescent substances, so easily can find and select Counterfeit Item (simulator).The characteristics of luminescence due to the security feature described in the publication only depends on the kind (ion of rare earth elements RE E) of alloy, therefore after the kind of the REE tentatively determining to use in safety notice, potential adulterator can be easy to select imitation Counterfeit Item, and as mentioned above, described Counterfeit Item can be substantially different in chemical composition from true material.
On the other hand, can utilize the Current developments of analytical technology come research and analysis easily in Stokes or anti-Stokes spectrum region with exciting light about the use of luminophor of launching.
WO 81/03509 A1,1981 is maximally related prior aries, which depict the secure file with luminous authentication feature, wherein, provide luminous exciting, and luminescence occurs in identical areas adjacent in the narrow region of wavelength.The document discloses a kind of for by optical excitation and to excite or the observation of the characteristics of luminescence comes the method (wherein, provide with spectroscopy mode near fluorescence radiation is launched excite) of the authenticity of authenticating security paper and a kind of method of wherein observing the decay of luminescence emissions in the SPECTRAL REGION of close excitation area.
This method comprises the detection of the decay of luminescence characteristic itself and other analytical approach significantly distinguished.But, due to following three main causes, compared with this method, the task of the security improving valuable document can not be solved completely:
1, the method uses known luminescent substance, which considerably simplifies the decoding of feature, and secondly simplifies search and the selection of Counterfeit Item.
Although 2 the method define emission band/excite wave band to be closely separated by, described emission band and excite wave band not overlap.Meanwhile, we can suppose that the spectral width (that is, according to the spectral range used, Δ λ is from 5 to 30nm) of the semiconductor laser by being used as emissive source determines the spectral resolution of the method.
3, in the emission spectrum of compound, the method is not open by the additional Stokes of available analytical approach record or the shortage of anti-Stokes wave band, by described available analytical approach, described compound can be detected and be present in the fact in safety notice; And in the excitation spectrum of described compound, the method openly shortage be positioned at the extra wave band beyond main registration (registration) region, under the exposure of described main registration region, can by can analytical approach carry out detection material, and the existence of this material in safety notice can be detected according to the Stokes of induction and/or the existence of Anti-Stokes emissions.
