8. with the coding (4) on the shooting mobile phone of resolution of lens >=8,000,000 pixels scanning stock (2) or/and picture and text (5), (4) information of encoding is uploaded to computing machine anti-fake network inquiry system, recalls corresponding anti-counterfeiting characteristic record information and it to be compared with the feature of personalized toothed edge (6) by shooting mobile phone and identify.
9. described coding (4) is or/and the upper regional area of picture and text (5) has personalized toothed edge (6); Or, described coding (4) is or/and the personalized toothed edge (6) of the upper regional area of picture and text (5) is exaggerated shooting, the toothed edge feature photo (8) of this regional area is taken as anti-counterfeiting characteristic record information, in other words, in order to alleviate database purchase pressure, in order to save data traffic, in order to improve inquiry velocity, the partial enlargement that shooting stores personalized toothed edge (6) is taken pictures, and just seeming is highly profitable.
10. described enlargement ratio n, can also see coding (4) clearly from photographed toothed edge feature photo (8) with naked eyes or/and the shape of printing net-point in picture and text (5) or single ink dot (21) is for established standards; Or described (on average) size (S) is 1mm 2sawtooth at least take by the resolution of 225 or 529 or 900 or 2025 or 4900 pixels and present (bust shot).
The present inventor finds in applied research, the personalized toothed edge (6) of ink that curtain coating or diffusion Light deformation are formed, its ink colors presents excessive formula and shoals, easily cause personalized toothed edge (6) soft edge unclear, then cause not easy to identify, especially not easily identified by Antiforge inquiry APP.For solving this difficult problem, ensure personalized toothed edge (6) clear-cut, preferably: after spray printing before drying, first cold stamping film (10) is covered and form coding (4) or/and the e-inks (3) of picture and text (5) is gone up and used pressure roller (9) to compress, cold stamping film (10) is peeled off again after drying lamp (19) drying, thus the part transfer layer (7) on cold stamping film (10) is transferred to coding (4) or/and on picture and text (5), make coding (4) or/and picture and text (5) have clear-cut, the personalized toothed edge (6) that teeth sizes (S) is larger.So, the personalized toothed edge (6) of ambiguous ink is just converted to apparent, the personalized toothed edge of teeth sizes (S) is larger transfer layer (7) (6).In other words, encode (4) or/and the transfer of picture and text (5) top has corresponding transfer layer (7).Here, e-inks (3) act as the effect of cold wave glue, this is the pioneering application of the present inventor, therefore, also electronics glue can be referred to as, it is for clinging transfer layer (7) and transferring to coding (4) or/and picture and text (5) top, simultaneously because e-inks (3) is transferred layer (7) and pressure roller (9) has rolled, so transfer layer (7) teeth sizes (S) of producing comparatively greatly, obviously easily distinguish.
Certainly, with golden blanching film (10), golden picture and text (5) thermoprint is transferred on scraggly stock (2), thus make picture and text (5) have the personalized toothed edge (6) of metallic luster, be also a kind of feasible method.
In order to improve imitated threshold, coding (4) can be improved or/and the individualized feature of picture and text (5) top transfer layer (7), such as: upper some laser patterns of mold pressing of the transfer layer (7) in cold stamping film (10) or lines; Or the upper print in advance of the transfer layer (7) in cold stamping film (10) establishes some colorful lines or patterns.So, coding (4) is or/and the individualized feature information of picture and text (5) top transfer layer (7)---i.e. one section of laser pattern of random intercepting or lines or colorful lines or colourful pattern, also can take pictures in the lump collect to be stored in computing machine anti-fake network inquiry system database as anti-counterfeiting characteristic record information, alternatively individualized security feature record information, check further in order to the public and tell truth from falsehood.
In other words, to encode (4) or/and on picture and text (5) top transfer layer (7), random one section of laser pattern intercepting or one section of lines or one section of colorful lines or one section of colourful pattern, take pictures to collect to be stored in computing machine anti-fake network inquiry system database, as another kind of individualized security feature record information and put on record, check further for the public and tell truth from falsehood.
In sum, described handset identity coding sawtooth method for anti-counterfeit, is characterized in that, at least comprise 1. following ~ 6. in one (preferably several techniques scheme Combination application).
1. described transfer layer (7) patrix is pressed with some laser patterns or lines.
2. the upper print of described transfer layer (7) is provided with colorful lines or pattern.
3. inner the mixing of described transfer layer (7) has some fine-powders, fine-powder is transferred at coding (4) or/and on picture and text (5), the random distribution characteristic of fine-powder as another kind of anti-counterfeiting characteristic record information, be collectedly stored in computing machine anti-fake network inquiry system database; It is in kind that fine-powder described here had both comprised real fine-powder, also comprises the same flaw in printing of virtual fine-powder, prints color point, gold-plated spot, silver-plated spot etc.
4. described coding (4) is or/and transfer layer (7) top of picture and text (5), is also coated with a transparent delustring protective seam; Or described e-inks (3) is inner has participated in (3-5%'s) matting agent; Like this, e-inks (3) affects clapped toothed edge feature photo (8) quality because of reflective can just be eliminated; Such as white reflection point is the spitting image of being breach, and this breach both sides because of reflective generation are protruding, and look the same is sawtooth, in other words, in order to ensure photo and consistance in kind, just must eliminate this reflective.
5. described pressure roller (9) surface relief is uneven.
6. by described coding (4) or/and on picture and text (5) top transfer layer (7), random one section of laser pattern intercepting or one section of laser lines or one section of colorful lines or one section of colourful pattern, taking pictures to collect is stored in the computing machine anti-fake network inquiry system database of accessing Internet, as another kind of anti-counterfeiting characteristic record information, checks further tell truth from falsehood in order to the public.
In order to personalized toothed edge (6) accidental injury of the transfer layer (7) after gathering that prevents from taking pictures; thus cause archives and material object not to be inconsistent; cause erroneous judgement: described coding (4), or/and transfer layer (7) top of picture and text (5), is also coated with a protective clear layer.So, first go up protective clear layer and to take pictures again collection, archives and material object just can be avoided not to be inconsistent.
In order to improve imitated threshold, for the ease of identifying, the individualized feature of the personalized toothed edge (6) of transfer layer (7) can be strengthened, such as: make pressure roller (9) surface relief of cold stamping film (10) uneven.So, the pressure roller (9) of surface relief injustice applies uneven pressure just can to the not dry e-inks (3) in transfer layer (7) below, thus cause e-inks (3) to produce significantly random Light deformation, then strengthen the individualized feature of the personalized toothed edge (6) of transfer layer (7).
In order to ensure the quality of coding (4), the method of secondary spray printing can be taked, to encode (4) the leading spray printing in a part of region out, make this region without toothed edge, then, to encode again (4) another part region spray printing out, make this region produce personalized toothed edge (6).
In other words, described coding (4) is or/and the upper regional area of picture and text (5) has personalized toothed edge (6); Preferably encode (4) without personalized toothed edge (6), picture and text (5) corresponding with it have personalized toothed edge (6).
In order to improve forgery difficulty, the sawtooth on described personalized toothed edge (6) is by encode, and the toothed edge characteristic information of its personalized toothed edge (6) is by the character string of encode.Such as: have sawtooth to represent with 1, represent with 0 without sawtooth, in a stroke, serrate the putting in order of institute is arranged in character string to represent with 1 and 0.
In order to improve forgery difficulty, described picture and text (5) are preferably the point of some sizes (S)≤0.3mm (H) × 0.3mm (W), so, this point will be spliced by multiple printing net-point (21), and the personal characteristics of the personalized toothed edge (6) that it is formed will more obviously, easily be distinguished.Experiment display: this point is silk-screen point preferably.
Time delay drying of the present invention impels not dry e-inks (3) diffusion deformation to produce the method for personalized toothed edge (6), runs counter to existing ink-jet printing process technical standard.Existing ink-jet printing process technical standard is dry at once after requiring ink-jet, to prevent not dry e-inks (3) diffusion deformation.Therefore, existing ink-jet printing process technical standard requires the distance as far as possible shortened between shower nozzle to drying lamp, requires this distance≤150mm.Research display: distance >=170mm or 500mm between shower nozzle to drying lamp (19) or 800mm, the personalized toothed edge (6) that generic pixel mobile lens can photograph could be produced.Or, finish-drying solidification is played when ink (3) prints off, period dry duration >=0.1 used second or 1 second or 60 seconds or 3 hours or 8 hours, like this, wait for that e-inks (3) is slowly dry, just can fully make it spread flushing, thus produce satisfactory personalized toothed edge (6).
It is appreciated that stock of the present invention (2) is the packing materials such as aluminum-plastic blister, described anti-counterfeiting characteristic record information is aluminum-plastic blister is encoded (4) or/and micro-damage vestige (16) information of picture and text (5).
In order to make up the mass defect of that occur in production run, a small amount of personalized toothed edge (6) feature not obvious (such as without sawtooth).There is the printing of the ink of fine-powder to form it is appreciated that picture and text of the present invention (5) adopt to mix, the wherein size >=0.01mm of fine-powder, or described stock (2) has the fine-powder of some stochastic distribution; The random distribution characteristic of described fine-powder, be also exaggerated shooting, its distribution characteristics information is stored in computing machine anti-fake network inquiry system database as another kind of anti-counterfeiting characteristic record information.Fine-powder described here comprises various shape, the circle of such as shades of colour, square, triangle, hexagon, strip, staple fibre etc.So, even without personalized toothed edge (6), also can verify the distribution characteristics of fine-powder, thus discern the false from the genuine.
Preferably, transfer layer of the present invention (7) is inner mixes some fine-powders, fine-powder is transferred to coding (4) or/and on picture and text (5), and the random distribution characteristic of fine-powder is put on record in computing machine anti-fake network inquiry system database as another kind of anti-counterfeiting characteristic record information, collection.
Research display: adopt the coding (4) of the ink jet printing mode institute spray printings such as UV ink, aqueous ink, oil solvent ink or/and picture and text (5), its personalized toothed edge (6) is the most obvious, is specially adapted to the present invention and uses.This is because: current the sprayed ink volume of ink-jet printer is 3 ~ 30 picoliters---i.e. a single ink dot (21), any coding (4) of institute's spray printing and picture and text (5) are all arranged in a combination by single ink dot (21) one by one, and single ink dot (21) rushes at stock (2) with very high speed, therefore, each single ink dot (21) is inevitable to be splashed on stock (2), thus is deformed into the personalized toothed edge (6) of different single ink dot (21).In other words, described in there is the coding (4) of personalized toothed edge (6) or/and picture and text (5), preferably use ink-jet printer (1) spray printing.Research also shows: on the paper that wetting property is good and in the strong coating of diffusivity, spray printing coding (4) is or/and picture and text (5), and its personalized toothed edge (6) also clearly.Such as: exempting from sized paper, slack sized paper, hydrophilic coating spray printing coding (4) or/and picture and text (5), without the need to taking the ancillary methods such as extruding, blowing, its personalized toothed edge (6) is with regard to clearly.
The shooting mobile phone had due to the public varies, shooting level height is different, shooting environmental light is different, therefore, the scene photograph in kind (18) about personalized toothed edge (6) captured during qualification commodity true and false, quality also can vary, some scene photographs in kind (18) are always had not meet quality requirements, computing machine anti-fake network inquiry system is difficult to it automatically to identify, for solving this difficult problem, the present invention devises following technical solution.
Computing machine anti-fake network inquiry system receives scene photograph (18) that (public) shooting mobile phone transmits and coding (4) thereof afterwards (if system software can not complete automatic identification), recall according to coding (4) the toothed edge feature photo (8) that in database, (storage) is corresponding, this photo is file photo; Scene photograph (18) and file photo are shown on the work computer display screen of assistant identification personnel in the lump; Then, whether the personalized toothed edge (6) identified on scene photograph in kind (18) by assistant identification personal observations is identical with the personalized toothed edge (6) on file photo, thus manually make true and false conclusion, and expert's conclusion information is fed back on (public) shooting mobile phone by computing machine anti-fake network inquiry system.

Size >=0.05mm (the H) × 0.05mm (W) of single sawtooth of the present invention, the setting of this technical characteristic, be not easy to expect very much, be hard-won.Research display: that the public commonly uses, that popularity rate is the highest existing shooting mobile phone, the resolution of its pick-up lens is 800 ~ 1,300 ten thousand pixels, adopt these mobile phone lens to the upper printed coding (4) of stock (2) or/and picture and text (5) are taken pictures, then taken a picture amplification is checked, the public therefrom can see printed, coding (4) clearly or/and on picture and text (5), the minimum dimension of single sawtooth is 0.05mm (H) × 0.05mm (W).In order to ensure personalized toothed edge (6) of the present invention, can be identified by after public's mobile phone photograph, meet the second key element of anti-counterfeiting technology three elements---be easy to identify, the present invention just selectes size (S) >=0.05mm (H) × 0.05mm (W) this technical parameter of single sawtooth.The setting of this parameter, make coding (4) or/and when picture and text (5) are with the naked eye normally watched, edge is neat, do not affect the appearance, without quality complain, and with shooting mobile phone take pictures, amplify check time, personalized toothed edge (6) can be seen clearly, thus be convenient to the public and tell truth from falsehood.
Naked eyes of the present invention seem that edge is neat, and general reference naked eyes see that substantially meeting printing quality national standard or company standard or user's specification or user accepts standard, such as: bar code, Quick Response Code, reaches C level printing standard.In other words, described edge is neat, and people's naked eyes of general reference normal vision directly go to see coding (4) or/and the edge of picture and text (5), cannot see or see the sawtooth on not too clear edge.In practice; some user may like the deckle-edged printed matter of word edge tool on the contrary; as long as so user receives the deckle-edged printed matter of tool, its application (namely becoming bad application) also belongs to the rights protection scope of " naked eyes seem that edge is neat " of the present invention.
The toothed edge characteristic information of personalized toothed edge (6) of the present invention, preferably toothed edge feature photo (8); Can certainly be the positional information of several selective examination points from personalized toothed edge (6) extraction, chart or coordinate data etc.; Can also be the coordinate curve, polar plot etc. that can reflect personalized toothed edge (6) feature.
Interference stripes of the present invention (14), make a general reference various figure, word, symbol, lines, assorted point and the foreground picture formed thereof or Background (such as simulating the Background in face of undertaking the printing of) etc., often open the interference stripes (14) in simulation photo (15), preferably not identical.So, just can increase fake producer will simulate photo (15) and be reduced into original electronic file (13), the difficulty using digital printer (1) secondary printing to fake again and cost.In other words, after printing, the coding (4) with personalized toothed edge (6) generated with software (automatically) is or/and the e-file (13) of picture and text (5) has been modified to the simulation photo (15) with interference stripes (14), simulation photo (15) is upper because having had more interference stripes (14), and directly cannot print use, fraud must could be printed after artificial removal's interference stripes (14), so, just significantly improve fraud cost thus improve imitated threshold.
Diffusant coating of the present invention is a kind of printing coatings printing being added with diffusant that the present inventor initiates, Existing commercial chemical products diffusant (product such as electric iron need) is added in the coating such as ink, required diffusant printing coatings can be configured, this diffusant coating, can come along coating surface diffusion rapidly by drippage water droplet thereon or ink droplet.
The scraggly stock in face of undertaking the printing of of the present invention (2), the printable fabric that the faces of undertaking the printing of such as its printable fabric used can be cambric paper, embossed paper, establishment cloth (being commonly called as snakeskin bagging), the medicine aluminum-plastic composite panel with salient point pit, crepe printing ink printing surface, foam ink printing surface, crackle ink printing face, frost flower ink printing face, multicolor finish spray-coating surface are coarse.
The present invention has done following analysis and research with regard to personalized toothed edge (6): 1, the Crack cause of personalized toothed edge (6): ink (3) natural diffuseness, compressive deformation or damage, shock splashing, inertia hangover etc.2, the formation period of personalized toothed edge (6): ink (3) is printed to one period after stock (2) is gone up before dry solidification.3, the influence factor of personalized toothed edge (6) shape: the morning and evening that the surface tension size in face of undertaking the printing of, wellability height, the diffusivity size of ink (3), the size of ink (3) pressurized external force, ink (3) stroke speed size, printing speed of a motor vehicle height, ambient humidity, ink (3) are dry.4, personalized toothed edge (6) distortion size is by the influence degree of typography: the deformation extent of the personalized toothed edge (6) that aqueous jet is formed is maximum, and influence degree is successively descending: aqueous jet printing, oiliness ink jet printing, cold wave transfer printing, UV ink jet printing, carbon ribbon printing, thermal printing, serigraphy, bat printing, gravure, flexo, offset printing etc.This result of study, specifically implements the present invention to user, should have certain directive significance.
Compared with prior art, the present invention can produce following beneficial effect.
One, do not need special printing, without quality complain: the coding (4) of some technique printing or/and picture and text (5) personalized toothed edge (6) in, single teeth sizes (S) natively meets application claims, be coding (4) or/and the feature that self has of picture and text (5), additional without the need to printing in addition.Compared with " rocking printing anti-counterfeit method (CN103358741B) " with background technology, its useful effect is: anti-counterfeiting characteristic does not need printing in addition to add, additionally can not increase printing cost, can not be thought by mistake be printing quality defect by the public yet.
Two, extremely difficulty copies: coding (4) or/and the personalized toothed edge (6) of picture and text (5) is ink (3) be printed onto stock (2) upper after, there is the individualized feature that random Light deformation formed again.The present inventor studies discovery: the coding (4) of many typography institutes such as ink jet printing spray printing is or/and picture and text (5), observe with magnifier, its edge is not smooth straight, and its edge always produces some random sawtooth caused because of reasons such as ink diffusion.In other words, described personalized toothed edge (6) prints rear ink incompleteness or diffusion or curtain coating to be out of shape generation, personalized toothed edge (6) is non-existent on forme (comprising printing original text), is individualized feature newly-increased after print.Even if " thief in the family " copy replicates real security code, has also copied anti-counterfeiting characteristic record information, even if copied the high definition photo of personalized toothed edge (6), when printing is faked again, its fake products coding (4) or/and picture and text (5) edge also inevitable random deformation again, thus must be different from the anti-counterfeiting characteristic record information in database.The present inventor did following experiment: the simplest numeral " 1 ", with No. 3 Song typefaces, use ink-jet printer, exempting from applying glue invoice paper prints 100 times, then with shooting mobile phone as magnifier, take pictures after enlarged photograph observe, find that this 100 " 1 " all can produce irregular personalized toothed edge (6) because of ink diffusion, the personalized toothed edge (6) not having two " 1 " is the same, in other words, see with magnifier, anyone cannot copy second " 1 " equally by spray printing again.In sum, the present invention initiatively using be randomly formed personalized toothed edge (6) bust shot record, as the foundation of discerning the false from the genuine, there is the characteristic of extremely difficult copying and forging, blocked the anti-counterfeiting technology leak of the existing digital false-proof technologies " a thief within a house is hard to guard against " such as code anti-fake with another more simple method.This beneficial effect, meets the first element of false proof three elements completely---is difficult to forge.In other words, compare code anti-fake technology, the present invention only have the number when code anti-fake to conform to and on its character limit, micro serrations that some are formed because of ink diffusion also conforms to, and just determines it is genuine piece.
Three, be easy to identify: the Quick Response Code scanning software in existing shooting mobile phone, such as micro-letter sweep sweep, QQ sweep sweep, I see sweep sweep, Baidu sweep sweep, Taobao sweeps and sweeps, all can recall coding (4) or/and the toothed edge feature photo (8) of picture and text (5), broad masses of the people by the magnifying function of shooting mobile phone, can check whether the toothed edge that micro serrations arranges conforms to, discerns the false from the genuine.This beneficial effect, meets the second key element of false proof three elements completely---is easy to identify.
After four, the public downloads special anti-counterfeiting inquiry APP, available shooting mobile phone scanning encoding (4) is or/and picture and text (5), and whether the personalized toothed edge (6) of automatic Verification conforms to, and distinguish true from false when the time comes by more convenient.
Five, enforcement is extremely easy: such as existing medicine electronic supervision code (4) is according to anti-counterfeiting technology of the present invention, then only need articles for use pick up machine product pick up time, preserve amplification (high definition) photo of medicine electronic supervision code (4) and personalized toothed edge (6) thereof in passing, then by photo storage in computing machine anti-fake network inquiry system database.In other words, compared to the background technology multiple prior art such as " rock printing anti-counterfeit method (notification number CN103358741B) ", the present invention is without the need to increasing equipment investment (without the need to rocking device), not increasing operation, do not increase cost, not reducing coding and picture and text printing quality, but impart the antiforge function adopting the products such as medicine electronic supervision code, block the leak of the digital false-proof technologies such as code anti-fake " a thief within a house is hard to guard against ".
Six, amplify identify extremely easily, very practical: the public can utilize mobile phone camera function, macro mode is adopted to take coding (4) on a sheet of printing stock (2) or/and picture and text (5) photo, and then photo is amplified, observe its personalized toothed edge (6) and whether conform to the toothed edge feature photo (8) transferring (browsing) and discern the false from the genuine, without the need to being equipped with magnifier special.In other words, the magnifier needed for personalized toothed edge (6) of the present invention can be seen clearly, just have ready-made software in existing shooting mobile phone, purchase magnifier material object specially without the need to the public.In other words, adopt product of the present invention, the public identifies easily, technology is very practical.
Seven, the present invention is especially creative, and the technical parameter of size (S) >=0.05mm (the H) × 0.05mm (W) of single sawtooth is selected.The sawtooth of this size (S), be world today's main flow mobile phone (resolution of lens >=8,000,000 pixels) can microshot, amplify minimum (object) size of watching clearly, this size selected, as the sawtooth standard of personalized toothed edge (6), meets the active demand that domestic broad masses of the people more than 1,000,000,000 distinguish true from false.In other words, size (S) >=0.05mm (the H) × 0.05mm (W) of selected single sawtooth ensures that broad masses of the people can use shooting mobile phone to distinguish the technical guarantee of authenticity of products.Otherwise if the size of single sawtooth (S) < 0.05mm (H) × 0.05mm (W), broad masses of the people are just difficult to use shooting mobile phone to distinguish authenticity of products, just can not realize object of the present invention.Just because of present invention accomplishes the condition that broad masses of the people tell truth from falsehood, so, the invention belongs to popular false proof (false proof also known as the public), instead of expert is false proof.
Eight, permanently effective: in sum, the personalized toothed edge (6) of the present invention is copied (almost cannot copy), is easy to identify due to extremely difficulty, and therefore, it is a permanently effective anti-counterfeiting technology necessarily.This beneficial effect, meets the three elements of false proof three elements completely---and permanently effective.

Embodiment one: adopt the present invention to make a kind of medicine electronic supervision code---coding (4).
As shown in Fig. 1, Fig. 5, Fig. 9, on a production line, the printing machines (1) such as UV ink jet numbering machine are adopted to carry out coding to stocks (2) such as the medicine boxs that conveying is come, thus produce the medicine electronic supervision code with personalized toothed edge (6)---coding (4), this coding (4) naked eyes seem that edge is substantially neat, reach C level printing standard.
In order to impel bar thick stick and the character generation Light deformation of medicine electronic supervision code, thus produce the personalized toothed edge (6) of size (S) >=0.05mm (the H) × 0.05mm (W) of more significant, single sawtooth.Can position between ink-jet printer (1) and UV drying lamp (19), air pressure gun in erection, the high pressure draughts such as high wind (11) are blowed to the not dry e-inks (3) of institute's spray printing, impelled bar thick stick and the character generation curtain coating Light deformation of medicine electronic supervision code by blast.Certainly, during concrete enforcement, also non-sticky roller (9) can be adopted to roll (printed by various typography) not dry e-inks (3), force printing net-point, ink dot and character edge generation Light deformation, thus produce meet designing requirement of the present invention, the sawtooth of some (not being whole) size (S) >=0.05mm (H) × 0.05mm (W).Here it should be noted that, existing typography forbids rolling or swiping not dry ink (3) after printing, in order to avoid the fuzzy distortion of printing word.The personalized toothed edge (6) of the medicine electronic supervision code of such making, its deficiency is: have gradient color, soft edge unclear, see Fig. 9.
Prepare technical grade optic micro distance lens digital camera (12) again, medicine electronic supervision code that is dried, that create personalized toothed edge (6) is carried out amplification take pictures, enlargement factor n with naked eyes can from take toothed edge feature photo (8) see personalized toothed edge (6) clearly for established standards; Wherein 50 >=n >=4 or 8 or 16 or 32 or 49 better; Preferably certain the character edge in medicine electronic supervision code is carried out the bust shot (microscopic photography) being greater than 150 times, the toothed edge characteristic information of personalized toothed edge (6), combination coding (4) information are stored in computing machine anti-fake network inquiry system database together, as anti-counterfeiting characteristic record information (foundation of namely discerning the false from the genuine), check the true and false in order to the public.
The public is with screen >=4 inch, after the shooting mobile phone of resolution of lens >=8,000,000 pixels pays close attention to micro-letter public account number or after the Antiforge inquiry APP downloading special exploitation for this reason, with regard to the coding (4) on available shooting mobile phone (as macrophotography machine) bust shot one sheet of printing stock (2) that closely (is such as less than 65mm) or/and the enlarged photograph of picture and text (5)---toothed edge feature photo (8), the characteristic information of toothed edge feature photo (8) etc. and coding (4) information thereof are uploaded together (comprise and use note or multimedia message to send) to computing machine anti-fake network inquiry system database, by computing machine Antiforge inquiry system by it (feature of the new toothed edge clapped) and anti-counterfeiting characteristic record information (feature of the toothed edge originally clapped) comparison, if coupling, then feed back conclusion be genuine information on shooting mobile phone, if do not mate, then feeding back conclusion is that false information is on shooting mobile phone.
According to above method spray printing, be out of shape, take pictures, the medicine electronic supervision code put on record or Quick Response Code, when consumer use be equipped with micro-letter, Baidu, Taobao, I see, pat the shooting mobile phone scanning of softwares such as seeing time, just can recall toothed edge feature photo (8) by (also can with PC computer machine) log into thr computer anti-fake network inquiry system database---file photo; Again with personalized toothed edge (6) photo---the scene photograph (18) of the shooting mobile phone (as macrophotography machine) of another portion (or same portion) screen >=4 inch, the resolution of lens >=8,000,000 pixels bust shot medicine electronic supervision code that closely (is such as less than 65mm), on Mobile phone screen amplify this scene photograph (18), the personalized toothed edge (6) examined on two photos feature, whether conform to completely, just can from evident.In order to discern the false from the genuine more easily, consumer can download to pat in the future and see Antiforge inquiry APP, realizes automatic comparison, automatically discerns the false from the genuine.
The coding such as the Quick Response Codes on the shooting mobile phone scanning shoot stock (2) of the public's also available resolution of lens >=8,000,000 pixels (4) or/and picture and text (5), thus obtain the scene photograph (18) of coding (4) information and personalized toothed edge (6); Coding (4) information obtained according to scanning again from computing machine anti-fake network inquiry system database, recall the toothed edge feature photo (8) of personalized toothed edge (6), this photo is file photo; Use the scene photograph (18) of the shooting mobile phone of resolution of lens >=8,000,000 pixels (as macrophotography machine) the bust shot personalized toothed edge (6) that closely (is such as less than 65mm) again, by scene photograph (18) and file photo in the lump (with shielding) be shown on mobile phone screen; Then, whether the personalized toothed edge (6) on the scene photograph that detects by an unaided eye (18) is identical with the personalized toothed edge (6) on file photo, thus makes true and false judgement.
After the public downloads the Antiforge inquiry APP of special exploitation for this reason with the shooting mobile phone of screen >=4 inch, resolution of lens >=8,000,000 pixels, coding (4) also on available camera lens scanning stock (2) is or/and picture and text (5), (4) information of encoding is uploaded to computing machine anti-fake network inquiry system database, transfers corresponding anti-counterfeiting characteristic record information by shooting mobile phone by it (anti-counterfeiting characteristic record information) the toothed edge characteristic information comparison with personalized toothed edge (6); If coupling, then on shooting mobile phone, show conclusion is genuine information, if do not mate, then on shooting mobile phone, show conclusion is false information.
The public go back available onscreen >=4 inch, resolution of lens >=8,000,000 pixels the coding (4) of shooting mobile phone closely on (such as 55mm) bust shot one sheet of printing stock (2) or/and the photo of picture and text (5)---toothed edge feature photo (8), again photo is passed through note or the mode such as multimedia message or micro-letter public account, be sent in computing machine anti-fake network inquiry system database, thus wait for that computing machine anti-fake network inquiry system veritifies sawtooth features, make true and false conclusion.
The shooting mobile phone had due to the public varies, shooting level height is different, shooting environmental light is different, therefore, the scene photograph about personalized toothed edge (6) (18) captured during qualification commodity true and false, quality also can vary, some scene photographs (18) are always had not meet quality requirements, computing machine anti-fake network inquiry system is difficult to it automatically to identify, for solving this difficult problem, computing machine anti-fake network inquiry system can be received scene photograph (18) that (public) shooting mobile phone transmits and coding (4) thereof afterwards (if system software can not complete automatic identification), the toothed edge feature photo (8) that in database, (storage) is corresponding is recalled according to coding (4), this photo is file photo, scene photograph (18) and file photo are shown on the work computer display screen of assistant identification personnel in the lump, then, whether the personalized toothed edge (6) identified on scene photograph (18) by assistant identification personal observations is identical with the personalized toothed edge (6) on file photo, thus manually make true and false conclusion, and expert's conclusion information is fed back on (public) shooting mobile phone by computing machine anti-fake network inquiry system.
In order to strengthen copying and forging difficulty, prevent thief in the family from copying anti-counterfeiting characteristic record information and for faking, preferably adding a grenadine in camera lens front, thus photo up one-tenth interference stripes (14).So, even if photo stolen by internal work personnel copy, personation coding (4) out of foundation photo spray printing will have more a grenadine, so, will find that Counterfeit Item and genuine piece are not obviously inconsistent.Certainly, also can not add grenadine in camera lens front, and when photograph taking is formed, be added the interference stripes (14) of a similar grenadine by software simulation.
Embodiment two: adopt the present invention to make a kind of medicine electronic supervision code---coding (4).
As Fig. 1, Fig. 2, Fig. 4, shown in Figure 10, on track, the ink-jet printers (1) such as UV ink jet numbering machine are adopted to carry out coding to carrying certain stock (2) of coming, the e-inks (3) of institute's spray printing is served as cold wave glue, silver color laser cold stamping film (10) is posted up, peel off again after pressure roller (9) rolls, thus silver color transfer layer (7) is transferred to e-inks (3) get on, produce (without gradient color) of clear-cut, the medicine electronic supervision code of the personalized toothed edge (6) of size (S) >=0.05mm (the H) × 0.05mm (W) of some (not necessarily whole) single sawtooth.The medicine electronic supervision code of such making, advantage is: personalized toothed edge (6) clear-cut, without gradient color, be easy to Antiforge inquiry APP and automatically identify, and coding (4) surface has the laser picture and text of metallic luster or even personalization.The laser picture and text of this personalization are owing to intercepting from cold stamping film (10) at random, therefore extremely difficult secondary (intercepting) alignment, extremely difficulty copy fraud, and can be photographed together in company with personalized toothed edge (6) and be stored in computing machine anti-fake network inquiry system database, check for public's inquiry, tell truth from falsehood.
In order to false proof better, can by described coding (4) or/and on picture and text (5) top transfer layer (7), random one section of laser pattern intercepting or one section of laser lines or one section of colorful lines or one section of colourful pattern, taking pictures together to collect is stored in the computing machine anti-fake network inquiry system database of accessing Internet, as another kind of anti-counterfeiting characteristic record information, checks further tell truth from falsehood in order to the public.
The inner fine-powder that also can mix some stochastic distribution of described transfer layer (7), fine-powder is also shifted at coding (4) or/and on picture and text (5), and alternatively anti-counterfeiting characteristic record information, collection are put on record in computing machine anti-fake network inquiry system database by the random distribution characteristic of fine-powder.
For impelling bar thick stick and the character generation curtain coating Light deformation of medicine electronic supervision code, thus produce random personalized toothed edge (6).Pressure roller (9) can be set between ink-jet printer (1) and UV drying lamp (19), preferably roll surface is designed to scraggly roll surface, to extrude bar thick stick and the character of medicine electronic supervision code, make it that random curtain coating Light deformation, even scumming occur.
Prepare a digital camera (12) again, by after dry solidification, the medicine electronic supervision code that creates personalized toothed edge (6) takes pictures, and photo storage put on record in computing machine anti-fake network inquiry system database.
