Description
Technical field
The present invention relates to protection secure files (security document) from forging, and is used for shielded print
The instrument of the authenticity of brush product (for example, banknote (banknote) and blank security list and tax label and stamp) is verified.
Background technology
In the most effective and technically feasible method of authenticity for verifying the banknote with hiding security feature
A kind of method be to assess in safety sign composition or include in the substrate of banknote and secure file compound again
Radiation characteristic.Higher safety caused by chance the method provides high-performance, due to creating hiding security element
Rank and the ability of verification by non-contact method.
In terms of the high speed of banknote sorts (sorting) and the verification of its authenticity, these advantages have resulted in base
In the extensive use for the hiding security feature of the non-linear optical property of various inorganic compounds used.
For being only used for the such machine readable hiding feature verified by note validating equipment
Major requirement be that the reliability of scanning and people use conventional research method (being specially spectrum and luminesceence analysis method)
Difficult detectability.
Conventional secure file includes mark, i.e., transparent (crystalline) knot based on the ion with rare earth metal
The authentication feature (81/03507 A1 1981 of WO) of structure.Radiation and light activated absorption are happened at the visible of spectrum and close red
Outside in the region (IR), and there is the regional transmission that wherein compound only emits in the near-IR region.The document is also public
A kind of method of the authenticity for authenticating security documents is opened, wherein exciting radiation and induction radiation are divided into spy
Determine multiple channels of bandwidth；The gained array for measuring the induction radiation and measured value is used as authenticity standard.Authenticity
Analyze the intensity of the entire set only specific band (band) of consideration spectrum of parameter according to response.
Because the individual spectral of the induction radiation of the inorganic substances based on rare earth element is not its exclusive feature,
In this way the problem of, is its deficient powers of resistance to counterfeit (forgery)；These spectrum are well studied
And it can be determined by way of the arrangement of the energy level in rare earth, activator.Therefore, have similar sharp
Work agent, the even counterfeit with different chemical constituents can show similar or identical in specific spectral band
Induction radiation spectrum.
81/03510 A1 1981 of WO describe a kind of safety paper with the authentication feature formed by luminescent substance
(luminescent substance has the luminescent spectrum only in the invisible part of spectrum, and is also provided by black light sharp
Hair) and safety paper authenticity invisible verification method, wherein the safety paper is exposed to by light source with spectrum not
The excitation of visible part, and can be analyzed in the invisible of the spectrum based on wavelength or relaxation time by detection device
The light-emitting line emitted in part.
What this method was based on emitting according to the Stokes' law (Stokes'law) known to other technical fields
The use of luminophor, it is thus impossible to solve the problems, such as to improve the level of protection for making secure file from forgery.
2007/003531 A1,11.01.2007 of WO describe with stay in used in security document based on luminous material
The secure file of the security feature of material, the secure file include by the rare-earth oxide sulfate of the ion doping at least two types
Manufactured host lattice (host lattice).The luminescent material shows anti-Stokes luminescence and according to Stokes' law
It shines.The luminescent material includes two kinds of ingredients (constituent)：In different proportions doped with the yttrium oxysulfide of ytterbium/holmium and
Doped with the yttrium oxysulfide of ytterbium/erbium.
On the one hand, include using known luminescent substance as security feature the shortcomings that this method.Adulterator is possible can
Obtain the known luminescent substance, and in addition, fully know and have studied the combination of the characteristic of these luminescent substances, so
It can be easily found and select Counterfeit Item (simulator).Due to the security feature described in the publication the characteristics of luminescence only
Dependent on the type (ion of rare earth elements RE E) of dopant, therefore in the kind for primarily determining the REE used in safety sign
After class, potential adulterator can be easy to selection imitation Counterfeit Item, and as mentioned above, and the Counterfeit Item can be with
It is generally different in terms of chemical constituent with true material.
On the other hand, can using the Current developments of analytical technology come easily research and analysis in Stokes or anti-
In stokes spectrum region with exciting light in relation to the use of luminophor that emits.
81/03509 A1 of WO, 1981 be the maximally related prior art, and which depict with luminous authentication feature
Secure file, wherein provide luminous excitation in the narrow region of wavelength, and be happened at identical areas adjacent.
The document discloses a kind of authenticities observed to verify safety paper for by light excitation and excitation or the characteristics of luminescence
Method (wherein, nearby providing excitation with spectroscopy mode in fluorescence radiation radiation) and a kind of wherein in the light of close excitation area
The method for composing the decaying of observation luminous radiation in region.
This method includes the detection for the decay of luminescence characteristic for significantly distinguishing it with other analysis methods.However, by
In following three main causes, compared with this method, the task for the safety for improving valuable document cannot be fully solved：
1, this method uses known luminescent substance, and which considerably simplifies the decodings of feature, and secondly simplify imitated
The search and selection of product.
Although 2, this method defines radiation wave band/excitation wave band and is closely separated by, the radiation wave band and excitation wave
Section is misaligned.Meanwhile we can assume that by the spectral width of the semiconductor laser as radiation source (that is, according to using
Spectral region, Δ λ is from 5 to 30nm) determine the spectral resolution of this method.
3, in the radiation spectrum of compound, it is additional that this method does not have disclosure that can be recorded by available analysis method
The shortage of Stokes or anti-Stokes wave band can be detected the compound and be existed by the available analysis method
The fact in safety sign；And in the excitation spectrum of the compound, this method, which does not disclose to lack to be located at, mainly matches
Additional wave band other than accurate region (registration) can be by available under the exposure of the main registration region
Analysis method detect substance, and can be examined according to the presence of the Stokes of induction and/or anti-Stokes radiation
Survey presence of the substance in safety sign.
