Abstract
The present invention relates to a document anti-counterfeiting method, which aims at the counterfeiting of documents. The following anti-counterfeiting characteristic objects are added on the documents, such as optical variable devices (such as holograms), a character string (such as magnetic reading characters (MICR), OCR characters or bar codes), a random pattern mark, etc. The optical variable devices can be used as devices which can rapidly check the counterfeiting (without very high reliability); the character string and the random pattern can be together used as marks of high reliability which are used for distinguishing the counterfeiting and recognizing the identity of a single document. A read out device can read vectors of a recognition mark from the random pattern mark, the character string is used for searching a record in a data bank, and the vectors and corresponding vectors recorded in the data bank are compared. If the vectors of the recognition mark read out from the documents are not matched with the vectors of the recognition mark corresponding to the character string on the documents in the data bank, the documents are counterfeited, or changed or destroyed. If the recognition vectors read out from the documents are matched with the recognition vectors stored in the data bank, the documents can be reliably recognized as true documents.

Embodiment
Hologram 1 or other optically variable devices in Fig. 1, as a kind of pressure-sensitive sign or compound, hot pressing, casting, directly the mold pressing sign or by any in anti-counterfeit printing industry other known application process or technology be produced on the file 3.Optically variable device 1 is used as the preliminary Application in Anti-counterfeiting of first pass, because incomplete adulterator makes the hologram of the qualified optically variable device that do not come out.
Except optically variable device, character string 7 also is applied on the file.This character string can be a kind of continuous programming code (a serial number), a kind of name or a kind of random number code, and for example as checking other file or a batch file at checking respective files place or certain contents at respective files place.This character can be the character that bar code, alpha-numerical sign indicating number, magnetic (MICR) character or other can be read with human eye or machine.This mark can be visible or sightless, and for example, they can be printed as with common ink, perhaps, is printed as with the Yin Mo outside ultraviolet, Infrared fluorescence or those visible light absorbings spectrum.This character string by this index, can be found out the title or the number of file as name or Numerical Index in database.
At last, except optically variable device and character string, the present invention also is applied to a kind of random labelling 5 in the file.This random labelling can be that the specific region of a kind of magnetic oil ink dot, a kind of specific region of containing fluorescent grain, a kind of feature that contains light scattering or any other comprise that micropodia that machinery can be surveyed, enough is enough to have abundant distinctive characteristics, an extremely difficult microcosmic mark that repeats to copy.These attribute tags should be machine-readable.For example, a kind of magnetic oil ink dot that has comprised the microscopic particles of tremendous amount, its particulate has position and direction at random, and any MICR is like this.The high resolving power magnetic reading head that uses in detecting reader and magnetic stripe detection reader detects the mean change of the regional area character of magnetic ink particle usually, is got rid of and usually incoherent noise is used as in the variation of high frequency.But, this so-called noise but be one unique, distinctive mark at random, it all is the same when reading at every turn, so if distinctive mark and continuous programming code are together to be stored in the database at random for these, perhaps distinctive tab character string is can be with a kind of safe cryptographic technique by distinctive mark derivation at random at random, and the above-mentioned like this mark of distinctive at random just can be used to identify the validity of file.
Make random labeled another kind of method and be and use a kind of fluorescent particles that comprises, lead the printing ink of particle as quantum dot array or fluorescent dye coating polystyrene spheres or dyestuff coating nanometer size electricity.In these cases, available low-light spectrophotometer is read the stochastic distribution of particle, and this low-light spectrophotometer only illuminates a minimum zone (at several microns the order of magnitude), and analyzes the fluorescence that particle sends in this zone.For example, this readout device can use wave filter to filter some part of electromagnetic wave spectrum, and perhaps it can separately analyze spectrum its entire portion or wherein a part of.Can go to analyze the time response of the fluorescent particles of random pattern mark with time-resolved spectroscopy.
Making random labeled another method is oneself can form heterogeneity with a kind of, as difference refraction axial ratio, and different-thickness, different birefringences, different birefringence axis is to, different absorption spectrums, or the material of other different optical characteristics prints.For example, a kind of aqueous solution of being dissolved in by salt and sugar can spontaneously be formed small pure salt crystallization and the sugared crystallization with different refractivity.Some pigment or coating can form the mesh-shape surface structure after becoming dry.The soft gelatin of one deck immerses earlier to immerse in the alcohol in the water again and can form reticulate texture.Formed zone typically has the random orientations distribution in these situations, can be as the mark of random character.
Making random labeled another kind of method is a certain zonule record or a kind of hologram of hot pressing on file, and a kind of interference figure of hologram is at random basically.The ablation technology that for example can use high power pulsed laser relates to figure at file upslide blackberry lily, thereby can write down a kind of hologram pattern to form random labelling; In all practical applications, by STOCHASTIC DIFFUSION body in the application conoscope image generation device and the different relevant position that diffuser is moved to the mark of respectively noting, but this interference figure of randomly changing.
Also having a kind of method of making random pattern is to specify that a specific zone serves as a mark on (border that for example prints out this piece zonule) on the file, and the random character that utilizes the random character of file base material inherence to serve as a mark.For example paper has readable fibre array at random, can use a pencil illumination this zonule to the paper, detects by the pattern of the light of the scattering of paper fiber to discern.
Implement method of the present invention
Implementing a method of the present invention can illustrate with Fig. 1 b, application be magnetic ink, as at MICR (identification of magnetic ink mark, the Magnetic InkCharacter Recognition) material that is being widely used in cashier's check coding.A kind of continuous programming code 17 usefulness MICR marks are imprinted on the file 13.19 of one of wherein a kind of predetermined MICR mark is designated as random labelling, simultaneously hologram with easy recognition image by hot padding on file, so that hologram has covered the MICR mark.After the printed and hologram of file is covered the MICR mark by hot pressing, use common MICR reading head (Fig. 2,210) read the MICR mark, come from that the MICR mark magnetic noise signal of above-mentioned appointment is then analyzed respectively comes out and be transformed into a vector, shown in Fig. 3 a and 3b, continuous programming code of being represented by the MICR mark and above-mentioned vector are sent to database server jointly and store with the form of data.All repeat identical process for each protected file.Afterwards, after file uses, can be for any one file by reading its MICR continuous programming code and vector with a readout device roughly the same once more, and and corresponding continuous programming code and vector in continuous programming code and the vector sum storehouse compared, discern the false from the genuine, shown in the diagram among Fig. 4 a and the 4b.If coding and vector the two can both with database in laid in be complementary and meet, just this file is judged as genuine piece.
Implementing second method of the present invention also can illustrate with Fig. 2, it utilizes a random pattern mark 226, be made on a kind of file that has a hologram, read this random pattern mark then, draw a distinctive label vector, for example by the magnetic signal distinctive mark of reading some sample points in the magnetic ink.The distinctive vector is encoded in the coding method that accesses to your password, and this password 222 is imprinted on the file as character string.Subsequent available a kind of reading/identification device by reading the random pattern mark and using identical step, derived a kind of password of representing mark, then password and character string compared, and this step explains through diagrams in Fig. 4 a.In this situation, must in readout device, insert this cryptographic algorithm.Its advantage provides and prevents that anyone from dismantling or analyzing the device that reader is found out its cryptographic algorithm.For example, if its box body is opened, perhaps some circuit is disconnected or power supply is interrupted, and provides the electronic interlocking device that cryptographic algorithm or its digital cipher are wiped from memory body etc.
Another implements method of the present invention is the laser of using through the random motion particle scattering, write down a kind of diffraction pattern of stochastic distribution, a kind of random pattern is provided, and this random pattern can be made among the hologram on the file, or be made in outside the hologram file partly on.This at random diffraction pattern can be made among the photosensitive medium, can fire method with laser, or be controlled by the physical step of diffraction pattern with other any one.If diffraction pattern is not made in the hologram, the predetermined place that can be made in file is for example on the hologram next door.After diffraction pattern writes down, and then with little close analysis diffraction pattern, become the file of a kind of bmp (bitmap) form with family planning, use a kind of key coding system will represent the number string of bitmap file to encode, the number string that will pass through coding then is imprinted on the file with bar code form, thereafter, this file can obtain the bmp file since reading its diffraction pattern once more, and verifies thus.Use same key that this bmp file is encoded,, then former and later two codings are compared to give file encoded number string.Before and after importantly will guaranteeing twice use accurately identical step read diffraction pattern, forming identical bmp file, or the bmp file is handled in normalization before the coding, has identical number string to guarantee identical diffraction pattern.
