Description
Technical field
The present invention relates to correlation techniques such as a kind of application mobile communication, printing, coding, Information hiding, the information that particularly relates to is imbedded the perfect adaptation of printing technology and mobile communication, makes that the user can really realize carrying out false proof Jianzhen to buying article whenever and wherever possible.
Background technology
In today that trade mark is on the increase, retaining a reputation is crucial thing.Yet, transaction issues about forgery best brand of product trade mark also is very serious, according to data, the dealing money of the annual fake products in the whole world can reach about 2,000 hundred million dollars, and at domestic 50,000,000,000 Renminbi that also reach of China, visible manufacturing and marketing the fake have become the second-biggest-in-the-world public hazards that are only second to traffic in drugs.
When producer from firing after the brand of researching and developing to that the marketing of going into operation works laboriously, it may will run into very pain in the neck feelings at once: this brand also not have just to become for oneself is commercial but very fast the prey that the counterfeiter chases.Hereafter, producer just have to a big chunk energy be placed on crack down on counterfeit goods on.But, manufacturer knows how many products he has produced himself, but be difficult to know, his product on earth by whom counterfeit and counterfeit what, so, cracked down on counterfeit goods into businessman's ten minutes pain in the neck feelings, if a solution can be arranged, cracking down on counterfeit goods of manufacturer's individual combat become the Jianzhen that all consumers participate in, so, thing has just become simply, and how many fake productss no matter who has made, and producer and businessman have been the genuine pieces of themselves production as long as help the consumer to identify which part product when buying commodity.
Replacing cracking down on counterfeit goods with Jianzhen is not new ideas, and the various solutions of similar thought also are that unrest is sewed in dim eyesight now, and are complete, but traditional Jianzhen's technology still exists many drawbacks in the circulation of commodities process, poor as technical monopoly and uniqueness; Easily forge and reveal core technology; Use inconvenient; The regular fee of anti-counterfeit recognition has been imputed to the consumer.Being embodied in of these problems:
(1) false proof, the fluorescence falsification preventing of the not high multiple laser anti-counterfeit of the technology content of anti-counterfeiting technology, a peacekeeping two-dimensional bar, anti-counterfeiting technology such as alternating temperature is false proof, visual watermark is false proof, really played better action in the early stage of development, but development afterwards is not fully up to expectations.Typical in laser anti-counterfeit, along with the development in market, counterfeit and shoddy goods have also adopted laser antifalsification technology.Other anti-counterfeiting technologies are as fluorescence falsification preventing, alternating temperature anti-false trademark.Visual watermark, concealed anti-false etc. because it is with low content of technology, very easily is decrypted and grasps, and are revealed easily and a large amount of fake products occur, even the imitated situation of anti-counterfeiting technology itself occurred.
(2) inquiry is inconvenient
Businessman often only emphasizes to have adopted any anti-counterfeiting technology in anti-counterfeit package, but how on earth discern or what effect different observational techniques has, most consumers are unknown, wherein some anti-counterfeiting technology is too loaded down with trivial details again, as import the bar code Help by Phone or by internet checking etc., this kind method for anti-counterfeit makes most consumers be difficult to identification and grasps, and is difficult to play anti-fake effect naturally.
3) can not buy before Jianzhen whenever and wherever possible
Traditional false proof service promptly allows to satisfy the function of true and false discriminating, as internet checking, SMS query etc., but because false proof plain code information must lean on visual identity after the strip of paper used for sealing of tearing, and all be to use once and cease to be in force automatically, so Jianzhen is and can only occurs in after the purchase, thing has been bought, and it is just pretty troublesome to return goods or handle relevant dispute.Such anti-counterfeiting technology is inequitable to the consumer.So those false proof producers are known as the preceding Jianzhen of the purchase that has realized now, in fact all are the deception consumer.
(4) technology innovation is slow, randomness is poor
In a single day many antiforge technology are used, and core technology is just unalterable.It can play anti-fake effect in a short time, but owing to not upgrading and improving, randomness is poor, is easy to be decoded by illegal molecule and utilize.Because the employed anti-counterfeiting mark of some anti-counterfeiting technologies does not change, no randomness, therefore, technology itself just is easy to be cracked and grasp.
(5) false proof market confusion
Present anti-counterfeiting technology produce market confusion, because most of anti-counterfeiting technologies need professional knowledge, common people are difficult for understanding in depth, and some anti-fake products that seem to be novel low performance are bait with the low price, and the people is had dust thrown into the eyes.This low-level anti-counterfeiting mark is easy to be palmed off at short notice.
Differentiate the method for genuine piece before the object of the present invention is to provide a kind of consumer of realization to buy whenever and wherever possible, the consumer uses according to service provided by the present invention, just can before buying, differentiate the true and false of commodity, this working of an invention, to play good fright effect to the fake producer, no matter make them have no exploits, be the goods producer, or businessman and consumer will therefrom benefit a great deal.

Concrete enforcement is as follows:
Method one: obtain to bury image such as Fig. 1 of computer data, convert this image color segmentation to C, M, Y, K four width of cloth color separated image such as Fig. 2, to Y image block such as Fig. 3 I (is enlarged drawing as the Y image of Fig. 2 as Fig. 3 I).Obtain average yellow value (full yellow is 0, and whole white is 255) as each piecemeal of Fig. 3 I.Set the benchmark piecemeal,, imbed computer data with 8 piecemeals around each benchmark piecemeal as A, B, the C... of Fig. 3 I.The method of imbedding computer data is to realize by the average yellow value that benchmark piecemeal 8 piecemeals on every side are set, the rule of imbedding computer data by the average yellow value of 8 piecemeals around the setting benchmark piecemeal is the average yellow value of piecemeal setting big certain setting value (yellow deviate) of average yellow value than benchmark piecemeal, this piecemeal is represented binary one, the average yellow value that certain piecemeal is set is than little certain setting value of average yellow value of benchmark piecemeal, this piecemeal is represented binary zero, perhaps the average yellow value of piecemeal setting is than average yellow certain setting value greatly that is worth of benchmark piecemeal, this piecemeal is represented binary zero, the average yellow value that certain piecemeal is set is than little certain setting value of average yellow value of benchmark piecemeal, this piecemeal is represented binary one, here might as well select the former with setting average yellow value representation computer data " 0 " " 1 " method, so just set up the corresponding relation of the average yellow value of binary computations machine data and benchmark piecemeal 8 piecemeals on every side.Average yellow value as the benchmark piecemeal can remain unchanged, and also can adjust.Now with as the benchmark piecemeal A of the I of Fig. 3 and around 8 piecemeals be that example describes the method for imbedding computer data in detail, for simplicity, 8 piecemeals around will reaching as the benchmark piecemeal A of Fig. 3 I are illustrated in the II place as Fig. 3 separately, No. 4 pieces (being benchmark piecemeal A piecemeal) are 0 for 9 piece piece numbers at center, 1,2,3,4,5,6,7,8, might as well establish the average yellow value of each piece and be respectively 100,120,140,130,160,180,105,125,190, the average yellow value of hence one can see that the center is No. 4 pieces is 160, set a yellow deviate and might as well be made as 40, average yellow value and yellow deviate that No. 4 pieces of benchmark piecemeal have been arranged just can have been buried computer data with 8 piecemeals around No. 4 pieces of benchmark piecemeal.The average yellow value setting of certain piecemeal in No. 4 pieces 8 piecemeals on every side is not less than 200 (the average yellow value 160 and yellow deviate 40 sums of benchmark piecemeal 4) and is set at binary one, is not more than 120 (the average yellow value 160 of benchmark piecemeal 4 is poor with yellow deviate 40) and is set at binary zero.Such as being the benchmark piecemeal with No. 4 pieces as Fig. 3 II now, it is 01010001 " Q " character that 8 piecemeals are on every side imbedded binary representation.Imbedding 01010001 order might as well be made as from left to right.Imbed so and be: first of 01010001 is " 0 ", the average yellow value of No. 0 piece is 100 to remain unchanged, because 100 less than 120, second of 01010001 is " 1 ", with the average yellow value of No. 1 piece is set is 200 to represent, the 3rd of 01010001 is " 0 ", with the average yellow value of No. 2 pieces is set is 120 to represent, the 4th of 01010001 is " 1 ", with the average yellow value of No. 3 pieces is set is 200 to represent, the 5th of 01010001 is " 0 ", with the average yellow value of No. 5 pieces is set is 120 to represent, the 6th of 01010001 is " 0 ", No. 6 the average yellow value of piece remains unchanged, because 105 less than 120, the 7th of 01010001 is " 0 ", with the average yellow value of No. 7 pieces is set is 120 to represent, the 8th of 01010001 is " 1 ", with the average yellow value of No. 8 pieces is set is 200 to represent, so just the binary number 01010001 of expression " Q " be embedded to the A piece be the center around in 8, as a same reason also can be with B, C... piece be the center around imbed computer data in 8, can imbed computer data in the whole Y image like this, the computer data that is embedded with can be encrypt or unencrypted, as above-mentioned " Q " just can be through cryptographic calculation and data.The Y image that is embedded with computer data with C, M, the K image is through screening, plate-making or directly make a plate, be printed as the printed matter that is embedded with computer data or convert the RGB image to is printed as the printed matter that is embedded with computer data through printer.
Method two: image such as Fig. 1 of obtaining to bury computer data, this image transitions is become C, M, Y, K four width of cloth image such as Fig. 2, to C, M, Y, the K image is made screening and is handled the C that obtains through screening, M, Y, the K image, for before the difference screening and afterwards C, M, Y, the K image, we might as well establish the C after the screening, M, Y, the K image is C1, M1, Y1, K1 image such as Fig. 4, to Y1 image block (I as Fig. 5 is the site partial enlarged drawing of Fig. 4 Y1), selected piecemeal as benchmark is such as A, B... piece and calculate each piecemeal yellow pixel quantity (pixel is the least unit of this image, yellow pixel is meant the black site as Fig. 5 I, because should print Yellow ink in the place during printing, so might as well be called yellow pixel), yellow pixel quantity as the benchmark piecemeal can remain unchanged, and also can adjust.Determine benchmark piecemeal average yellow pixel quantity and set a yellow pixel deviate, so just can imbed computer data by the yellow pixel quantity of 8 piecemeals around the setting benchmark piecemeal, it is the mean pixel quantity of piecemeal setting big certain setting value (yellow pixel deviate) of average yellow pixel quantity than benchmark piecemeal that the rule of imbedding computer data with the average yellow pixel quantity of 8 piecemeals is set, this piecemeal is represented binary one, the average yellow pixel quantity that certain piecemeal is set is than little certain setting value of average yellow pixel quantity of benchmark piecemeal, this piecemeal is represented binary zero, perhaps the average yellow pixel quantity of piecemeal setting is than big certain setting value of average yellow pixel quantity of benchmark piecemeal, this piecemeal is represented binary zero, the average yellow pixel quantity that certain piecemeal is set is than little certain setting value of average yellow pixel quantity of benchmark piecemeal, this piecemeal is represented binary one, here might as well select the former method, so just set up the one-to-one relationship of the average yellow pixel quantity of binary computations machine data and benchmark piecemeal 8 piecemeals on every side with average yellow pixel quantitaes binary zero " 1 ".Now with as the benchmark piecemeal A of the I of Fig. 5 and around 8 piecemeals be that example describes the method for imbedding computer data in detail, for simplicity, 8 piecemeals around will reaching as the benchmark piecemeal A of Fig. 5 I are illustrated in the II place as Fig. 5 separately, No. 4 pieces (being benchmark piecemeal A piecemeal) are 0 for 9 piece piece numbers at center, 1,2,3,4,5,6,7,8, might as well establish the average yellow pixel quantity of each piece and be respectively 170,170,170,170,150,125,170,95,170, the center is that the average yellow pixel quantity of No. 4 pieces is 150, set a yellow pixel volume deviation value and might as well be made as 40, average yellow pixel quantity and yellow pixel volume deviation value that No. 4 pieces of benchmark piecemeal have been arranged just can have been buried computer data with 8 piecemeals around No. 4 pieces of benchmark piecemeal.The average yellow pixel quantity of the piecemeal in No. 4 pieces 8 piecemeals on every side is set to be not less than 190 (the average yellow pixel quantity 150 and yellow pixel volume deviation value 40 sums of benchmark piecemeal 4) and is set at binary one, is not more than 110 (the average yellow pixel quantity 150 of benchmark piecemeal 4 is poor with yellow pixel volume deviation value 40) and is set at binary zero.Such as being the benchmark piecemeal with No. 4 pieces as Fig. 5 II now, it is 01010001 " Q " character that 8 piecemeals are on every side imbedded binary representation.Imbedding 01010001 order might as well be made as from left to right.01010001 first is " 0 " so, No. 0 average yellow pixel quantity of piece is 170 to change into 110 expression binary zeroes, second of 01010001 is " 1 ", No. 1 average yellow pixel quantity of piece is 170 to change into 190 expression binary ones, the 3rd of 01010001 is " 0 ", No. 2 average yellow pixel quantity of piece is 170 to change into 110 expression binary zeroes, the 4th of 01010001 is " 1 ", No. 3 average yellow pixel quantity of piece is 170 to change into 190 expression binary ones, the 5th of 01010001 is " 0 ", No. 5 average yellow pixel quantity of piece is 125 to change into 110 expression binary zeroes, the 6th of 01010001 is " 0 ", No. 6 average yellow pixel quantity of piece is 170 to change into 110 expression binary zeroes, the 7th of 01010001 is " 0 ", No. 7 average site of piece pixel quantities are the 95 expression binary zeroes that remain unchanged, the 8th of 01010001 is " 1 ", No. 8 piece mean pixel quantity is 170 to change into 190 expression binary ones, so just " Q " of Binary Zero 1010001 expression be embedded to the A piece be the center around in 8, as a same reason also can with the B... piece be the center around imbed computer data in 8, can imbed computer data in the whole Y image like this, the computer data that is embedded with can be encrypt or unencrypted, as above-mentioned " Q " just can be through cryptographic calculation and data.The Y Screening Image that is embedded with computer data with C, M, K Screening Image through going out the film, plate-making or directly making a plate, be printed as printed matter.
