Embodiment
Consult Fig. 1, the process flow diagram of the first embodiment of the detection method of printed matter of the present invention, the method comprises:
Step 101: at least two the security element information and at least two the use mark informations that obtain printed matter;
Security element can the mark such as fluorescent material, shading and/or safety line on printed matter, also can be the patterns such as anti-fake mark, numeral number, bar code or Quick Response Code;
Using vestige can be user by hand-written or that print word, mark, also can be the mark that other objects produce, such as seal, fingerprint etc.;
Wherein, acquisition be adopt take pictures, scan, the mode such as to copy obtains printed matter anti-counterfeiting element and use the image of vestige;
On printed matter, security element has dominant with stealth, and stealthy security element will by the method inspection identification such as optical, electrical, magnetic, radiation, chemistry.Some false proof point is compounded with multiple anti-fake element to improve anti-forgery security, increases and imitates difficulty.What printed matter also had just can will be shown by the irradiation of special light sources, the needs at least two kinds of special light sources mixed exposures also had just can show MULTIPLE COMPOSITE antifalse effect, and these security element before acquisition, need to adopt corresponding special light sources to irradiate and light source will note the angle of irradiating when irradiating.
Step 102: detect at least two security element information to judge the true and false of the first relativeness between the true and false of at least two security element, at least two security element;
The true and false key detecting security element detects the true and false of security element material; Such as fluorescent material can not resolved fluorometric material be true fiber or picture in prior art, and present embodiment adopts exciting light to irradiate fluorescent material from different perspectives to detect the true and false of fluorescent material, can the fibrous material of resolved fluorometric material; Security element is generally the material that can play True-false distinguish effect, effect or the pattern that add in printed matter production run, generally just exists in printed matter before use printed matter.
The first relativeness detected between security element refers to the spatial relationship between multiple security element, angular relationship, color relationship or other corresponding relations, whether the air line distance of such as two security element meets standard, the situation of the cross-coincidence of two security element, whether the image breach of two security element can overlap completely, the identical security element of two shapes same light according under show different color etc., such as two security element are designed to irregular zigzag, the zigzag of two security element at that time on same printed matter can be engaged, not that two security element on same printed matter then can not be engaged.
Step 103: detect at least two use mark informations with judge at least two use the true and false of vestiges, at least two use the second relativeness between vestiges or at least two to use in vestiges third phase in any one and at least two security element between any one to the true and false of relation;
Use vestige can be the signature, fingerprint etc. of user, also can be the seal of adding a cover; Identification method can be compare with my signature, fingerprint etc. of prestoring, and judges the true and false; Vestige is used to be generally after printed matter is produced, the information of adding on printed matter in use procedure.The article genuine-fake that prior art is general is differentiated not adopt the mode detecting and use vestige, because use vestige has randomness, changeableness to a certain extent.
Relation between use vestige the most directly detects the distance between vestige, a lot of bills such as, can add a cover several seals simultaneously, in order to save time, generally use fixing for multiple seal combination simultaneously, can form fixing distance between several like this seal, the anglec of rotation of each seal also can be determined mutually.
Use the relation between vestige and security element can be use the distance between vestige and security element, may also be the relations such as the image overlapped both being.
Step 104: if the result of all every judgements is very, then output printed matter is genuine piece and is unique result;
If the first relation between security element and security element, use vestige and use the second relation between vestige, use the 3rd relation between vestige and security element to be very, then judge that this printed matter is as true, and this result is unique.
Step 105: if the result of all every judgements has any one to be pseudo-, then output printed matter is adulterant and is unique result.
Be different from prior art, present embodiment is by detecting the characteristic information of each security element and use vestige, the first relation between each security element, the second relation between each use vestige and the 3rd relation between security element and use vestige judge the true and false of printed matter, not only determine the true or false of former printed matter itself, namely the relativeness between the true and false of security element itself and the security element of random alignment, also determine the uniqueness using rear printed matter, namely the true and false of vestige itself is used, use the relativeness between vestige and the relativeness using vestige and security element, because the judgement of single security element and used aloned vestige is comparatively easy, and the position of each security element and use vestige, angle, arrangement all has randomness, make only to judge single security element or use the true and false of vestige itself well can not identify the true and false of printed matter, be easy to the situation causing erroneous judgement, and present embodiment is by judging multiple random security element and judging multiple random security element while using each own true and false of vestige and use the position relationship between vestige to identify printed matter, the true and false of printed matter is detected more accurate, safety.
Consult Fig. 2, the process flow diagram of the second embodiment of the detection method of printed matter of the present invention, the method comprises:
Step 201: obtain the image of bill under different preset light sources is irradiated respectively;
Different preset light sources comprises visible light source or invisible light source; Wherein, visible light source comprises: the composite light source that monochromatic source, at least two kinds of monochromatic sources are compounded to form; Invisible light source comprises: the composite light source that the infrared light supply of different wave length and ultraviolet source, at least two kinds of invisible light sources are compounded to form.
The making material adopted due to different security element is not identical, and the fluorescent material added is not identical yet, and therefore different security element can present different effects under different light source irradiation or under the complex light irradiation of Different Light, such as:
As shown in Figure 3, identical security element presents the image of different states under white light and infrared light supply:
Fig. 3 (a) is the image of security element under white light, and Fig. 3 (b) is the image of security element under infrared light, and Fig. 3 (c) is the image of security element under white light and infrared light complex light;
As shown in Figure 4, identical security element presents the image of different states under infrared light supply and ultraviolet source:
Fig. 4 (a) is the image of security element under infrared light, and Fig. 4 (b) is security element image under ultraviolet light, and Fig. 4 (c) is the image of security element under infrared light and ultraviolet light complex light.
Step 202: the coherent detection characteristic information of at least two security element in extraction image or at least two use vestiges;
One or more combination in the dynamic image that characteristic information comprises security element and uses the material of vestige, shape, size, angle, sharpness, line thickness, color, brightness, the position among bill, above-mentioned project to be formed under different preset light sources is sequentially irradiated;
Such as: adopt different fibrous materials to make security element, the width of safety line and color, use the draft bank of two different sharpness, each security element adopts different relative angle etc.
Wherein, concealed anti-false element presents different images under different light, when sequentially irradiating this concealed anti-false element with the light source of particular combination, just there will be dynamic effect; Such as under three kinds of Different Light are irradiated, present three kinds of different images.Control irradiation sequence and the time interval of three kinds of light sources, three kinds of images of change can be presented according to predefined procedure, and then the feature utilizing human eye vision to stop, in human eye, present predetermined dynamic image.
Wherein, use vestige as detection characteristic information is before printed matter is passed to the first counterparty; after the vestige that second counterparty is stayed on printed matter by artificial or use instrument or the marking; when being called that the article to be detected of printed matter are passed to the second counterparty or the 3rd counterparty by the first counterparty by the first counterparty, the corresponding use vestige on detected article to be detected.
Step 203: use the detection characteristic information of vestige to mate with corresponding pre-stored characteristics information at least two security element or at least two, if coupling, be judged as genuine piece, carry out step 204, otherwise be judged as adulterant, carry out step 206;
One or more combination in the dynamic image that the material of the use vestige of the acceptance bill that pre-stored characteristics information gathers when comprising the security element of blank printed matter and issue of bill that gather when printed matter dispatches from the factory, shape, size, angle, sharpness, line thickness, color, brightness, the position among bill, above-mentioned project are formed under different preset light sources is sequentially irradiated;
Such as: adopt different fibrous materials to make security element, the width of safety line and color, use the draft bank of two different sharpness, each security element adopts different relative angle etc.
Wherein, use vestige as detection characteristic information is before printed matter is passed to the first counterparty; after the vestige that second counterparty is stayed on printed matter by artificial or use instrument or the marking; when being called that the article to be detected of printed matter are passed to the second counterparty or the 3rd counterparty by the first counterparty by the first counterparty, the corresponding use vestige on detected article to be detected.
Step 204: the true and false detecting the first relativeness between at least two security element;
Because the judgement of single well-known security element is comparatively easy, therefore the security element detected is carried out in embodiment of the present invention, except can using single well-known security element such as watermark as except security element of the present invention, can also using the two or more security element be not known or usually can not be undertaken detecting by existing inspection machine as security element of the present invention, the decorative pattern on such as bank note or bill, texture.Cash inspecting machine can not check these decorative patterns or texture usually, and therefore the security element of these decorative patterns or texture and so on possesses hiding, is namely adopted by embodiment of the present invention.And the position of these security element such as decorative pattern or texture, angle, arrangement all have randomness, namely without any two identical printed matters; Such as, the shading on the different Renminbi of identical face amount, frame decorative pattern are all not identical.Embodiment of the present invention is ingenious to utilize on printed matter itself with these hidings, randomness security element, and this type of security element is defined as random anti-counterfeit element, using the relativeness between this type of random anti-counterfeit element two or more as detection characteristic information.Such as detect and judge the position relationship between two random anti-counterfeit elements, this position relationship can be distance, angle or other relativenesses between any two random anti-counterfeit elements.Like this, these random anti-counterfeit elements are natively difficult to the person of being imitated to be realized and finds exactly, even if imitated person knows detection is this type of random anti-counterfeit element, but random anti-counterfeit element on printed matter is very various, accurately which cannot navigate to; Even if be positioned to the random anti-counterfeit element carrying out detecting by chance, but the random anti-counterfeit element of another one or more is still had to find and cannot copy; Further again, even if obtain all random anti-counterfeit elements that will detect by modes such as theft trade secrets, because embodiment of the present invention is not detection random anti-counterfeit element, but the relativeness detected between two or more random anti-counterfeit element, this relativeness is random further on random basis, and possibility is innumerable.If therefore there is no answer, cannot determine at all.
Moreover, the region of often opening random anti-counterfeit element that printed matter carries out detecting or security element can be random, therefore the random anti-counterfeit element that printed matter carries out checking often is opened all not identical, therefore imitated person cannot batch duplicating, also the random anti-counterfeit element that will detect cannot accurately be navigated to, and then can guarantee, after enforcement embodiment of the present invention, can except determining the true and false of printed matter itself, can also determine that whether this printed matter is unique, namely that printed matter circulated away before being whether, and can not be held and to change or imitated and do not know.
As shown in Figure 5, bill 500 comprises draft bank 501, first security element 502, second security element 503 and safety line 504, can be judged the true and false of this bill by the distance between confirmation security element or angle;
Angle 506 between the horizontal line that vertical range 505, second security element 503 such as between the first security element 502 and safety line 504 is vertical with safety line.
Step 205: detect at least two and use the second relativeness between vestige or at least two to use in vestiges third phase in any one and at least two security element between any one to the true and false of relation;
Step 206: if the result of all every judgements is very, then output printed matter is genuine piece and is unique result;
Step 207: if the result of all every judgements has any one to be pseudo-, then output printed matter is adulterant and is unique result.
Be different from prior art, present embodiment adopts various light sources to irradiate security element, multiple monochromatic source and composite light source is particularly adopted to irradiate with characteristic information extraction respectively, compared by various features information and the characteristic information prestored, judge the true and false, in addition, because the judgement of single security element or used aloned vestige is comparatively easy, and the position of each security element and use vestige, angle, arrangement all has randomness, between each security element, the relation between vestige and between security element and use vestige is used to have uncertainty, by detecting the relation between security element, the relation between vestige and the relation between security element and use vestige is used to judge the true and false of printed matter, determine the uniqueness of printed matter, make testing process more rigorous, effectively prevent personation, the behaviors such as forgery, make printed matter more accurate, safer.
Consult Fig. 6, the process flow diagram of the 3rd embodiment of the detection method of printed matter of the present invention, the method comprises:
Step 601: at least two the security element information and at least two the use mark informations that obtain printed matter;
Step 602: detect at least two security element information to judge the true and false of the first relativeness between the true and false of at least two security element, at least two security element;
Step 603: the central point determining seal;
Step 604: determine the angle between the line of a certain unique point of seal and central point and horizontal line or perpendicular line;
As shown in Figure 7, determine the central point 702 of seal 701, then determine the size of the angle 706 between the line 704 of seal unique point 703 and central point 702 and horizontal line 705, thus judge the position of certain unique point in seal, be i.e. the anglec of rotation of seal.
Step 605: detect at least two and use the second relativeness between vestige or at least two to use in vestiges third phase in any one and at least two security element between any one to the true and false of relation;
As shown in Figure 8, although the anglec of rotation of seal a1, b1, c1 and seal a2, b2, c2 size, shape, unique point and unique point is separately all the same, be identical seal when namely once or repeatedly adding a cover multiple seal, but wherein seal b1 and b2 is different from the relative position of other seals, this has just run counter to the uniqueness using vestige, is therefore then judged to be puppet;
As shown in Figure 9, although seal a1, b1, c1 and seal a2, b2, c2 separately size, shape, unique point are all identical, be identical seal when namely once or repeatedly adding a cover multiple seal, but the anglec of rotation of seal b1, c1 and b2, c2 is different, this has just run counter to the uniqueness using vestige, is therefore then judged to be puppet;
Certainly, also using using position and the angle of vestige simultaneously as the standard judging the true and false, by Fig. 8 and Fig. 9 combination, no longer may illustrate here.
As shown in Figure 10, because security element 1003 may be positioned at any position of printed matter, therefore seal 1001 probably has different position relationships from security element 1003, determine that the position relationship of security element 1003 and seal 1001 also can adopt the mode of similar step 604, determine certain unique point 1004 of security element 1003, the Distance geometry then determining between unique point 1004 and the central point 1002 of seal 1001 is connected the angle between horizontal line.
Step 606: if the result of all every judgements is very, then output printed matter is genuine piece and is unique result;
Step 607: if the result of all every judgements has any one to be pseudo-, then output printed matter is adulterant and is unique result.
For bill, financial institution to before client's bill rendered without any use vestige, referred to herein as blank bill, but this blank bill has draft bank, the dispatch from the factory form, word and other the multiple security element that print, such as watermark, safety line, shading, hidden pattern etc., gather the relation information between multiple characteristic information and each security element such as the draft bank on this blank bill, security element and preserve individual features information; Financial institution to carry out to client's bill rendered signing or after the operation such as fingerprint with an official seal affixed to the signature on this acceptance bill, to affix one's seal or fingerprint etc. uses mark information and uses the relation information between mark information and security element carry out acquisition process and preserve individual features information; When detecting acceptance bill, the characteristic information of preservation is compared with acceptance bill successively, namely the first relation successively between the true and false of the security element of decides bill, security element, use the second relation between vestige and use the true and false of the 3rd relation between vestige and security element, only have is true time simultaneously, then judge that this acceptance bill is true.
Particularly, the first counterparty refers to client, and the second counterparty refers to the financial institution of bill rendered, and the 3rd counterparty refers to the financial institution receiving bill.Consult Figure 11 (a), when bank clerk need to client's first output 100,000 yuan indicate the bill A of draft bank a time, before filling in bill, bank clerk can first gather the relation information between the characteristic information of multiple security element on bill A and each security element and preserve individual features information as the first information, bill has been filled at bank clerk, after both sides sign and seal, bank clerk can gather the characteristic information of ticket A according to upper multiple use vestige again, relation information between each use vestige and use the relation information between vestige and security element and preserve individual features information as the second information, client takes away bill A, consult Figure 11 (b), when client's second with the bill B indicating draft bank b to banker's acceptance time, bank clerk is given by bill B, and claim that this bill B is bill A, first bank clerk checks that whether the draft bank b of bill B is identical with the draft bank first of bill A, detects under identical prerequisite to the security element on bill and use vestige again, bank clerk can first gather the relation information between the characteristic information of corresponding security element on bill B and each security element and preserve individual features information as the 3rd information, bank clerk can gather the characteristic information of corresponding use vestige on bill B again, relation information between each use vestige and use the relation information between vestige and security element and preserve individual features information as the 4th information, then by the 3rd information and first information comparison, 4th information and the second information comparison, only have all characteristic informations whole identical time, just exporting this bill is true and unique consequence, such as, although the 3rd information of bill B is identical with the first information, illustrate that bill B itself is genuine, but the amount of money on bill B is 1,000,000 yuan, yuan different from 100,000 in the second information, illustrate to be held by people and correct one's mistakes, want to gain 900,000 yuan that have more by cheating, then exporting this bill is false result.
Be different from prior art, present embodiment adopts various light sources to irradiate security element, multiple monochromatic source and composite light source is particularly adopted to irradiate with characteristic information extraction respectively, compared by various features information and the characteristic information prestored, judge the true and false, in addition, because the judgement of single security element or used aloned vestige is comparatively easy, and the position of each security element and use vestige, angle, arrangement all has randomness, between each security element, the relation between vestige and between security element and use vestige is used to have uncertainty, by detecting the relation between security element, the relation between vestige and the relation between security element and use vestige is used to judge the true and false of printed matter, determine the uniqueness of printed matter, make testing process more rigorous, effectively prevent personation, the behaviors such as forgery, make printed matter more accurate, safer.
