In addition, alleged in this manual " mark (marking) " except finger mark brush is handled, refers to that also mint-mark processing, relief sculpture treatment, etching and processing, laser labelling etc. are used for the various processing with state fix information content that can be visual.
Background technology
In recent years, be difficult to differentiate that the situation with the counterfeit listing of the exquisiteness of the difference of regular article increases day by day, in light of this situation, developed can differentiate the technology that counterfeit is a problem simply.Wherein, comprise following technology: will be encoded into optical information codes such as 2 d code or bar code at the information that each article is set respectively, and it is printed on (with reference to patent documentation 1,2) on the article with the character string corresponding to its code content.
Patent documentation 1: the publication communique 2003-44257 of Japan.
Patent documentation 2: the publication communique 2006-102364 of Japan.
But in patent documentation 1,2, the represented information of 2 d code is printed on the same target thing with the information that becomes its information source, therefore might understand encryption rule etc. according to the relation of two information.In addition, being printed with under the situation of dummy string or 2 d code, this forgery might can't be penetrated according to the encryption rule of being understood.
The present invention is conceived to the problems referred to above, and its problem is: make the relation between optical information code and the character string can't understood easily, thereby improve the reliability of each code, can judge exactly whether print content is correct.
Summary of the invention
The mark disposal system that the following describes, code judge that the invention of system, Articla management system, labeling method, code determination methods and information displaying forms in order to solve above-mentioned problem.
(1) the mark disposal system be for management article on article or its adjunct the system of mark optical information code and the code that constitutes by character string.This system has: storage unit, and its correspondence is stored the multiple information relevant with article relatedly, makes and can determine the one group information relevant with these article respectively to each article; The first code generation unit, it is at each article, utilize respectively in the described storage unit at the part in the confirmable one group of information of these article, generate and be used to represent these article first code of intrinsic content respectively; The second code generation unit, it generates second code respectively at each article, wherein, described second code comprises each article information of intrinsic content respectively in described one group of information, and the information that described second code comprised is not included in the first code; Optical information code generation unit, it is used to generate the optical information code of the described first code of expression; The string data generation unit, the conversion process that it is stipulated described second code, the data of the character string of generation tagged object; And indexing unit, it utilizes the optical information code of the described first code of expression and according to the string data that second code generates, carries out described mark and handle.
In technique scheme, preferably, comprise that with the corresponding message block of each article at least two kinds of contents are according to every kind of article and different information.Its reason is, the information of the content that in first code, second code, needs to comprise that respectively each article is intrinsic, and this information is information different between code.But, in message block, also can be included in information common between a plurality of article.First code, second code except above-mentioned intrinsic information, also can comprise the information common with other article too.
Sometimes storage unit is made of a plurality of storage arrangements physically.In addition, when the information that in first code, comprises according to article storage when individual other storage medium (for example, RFID label, IC chip etc.), these storage mediums are also included within the storage unit.
According to said system, first code that generates at identical items and second code as information source, and comprise the information of the intrinsic content of each article with common message block, so first code and second code have only one-to-one correspondence.Therefore, can make the optical information code of expression first code and the combination of the character string that generates from second code according to different article and difference.Therefore, identical or the optical information code is identical when the combination that has the reading of data that reads from the optical information code and character string, and during the different a plurality of article of character string, even in these article, have genuine article, also can be judged as and have only a genuine article, other are counterfeit.
In addition, string data is by second code being changed the data of generation, therefore, as long as do not know the rule of its conversion, just can't being deciphered second code.And, because contained information is the information of the intrinsic content of article in second code, and this information is not included in the first code, therefore, also can't utilize the code of its deciphering to forge the optical information code and the character string of the combination that is judged as regular article even decipher second code according to the character string that is marked on the regular article.
Like this, according to above-mentioned mark disposal system, the code that regular code is regarded in generating structure that can't come resolving code according to the optical information code and the character string of mark or forgery as.
(2) in a mode of above-mentioned mark disposal system, the information of the content that storage unit is intrinsic with each article difference is read and a message block that article are corresponding as keyword.In addition, the first code generation unit generate comprise the information that becomes described keyword (below, be referred to as " key word information ") code as described first code.
According to aforesaid way, when the judge mark content is whether correct, after reading first code, come the retrieve stored unit based on key word information contained in this code from the optical information code, can determine to constitute the information of second code thus.
(3) in the system of preferred mode, in storage unit, store the secret information that the supvr of article sets each article.In addition, the second code generation unit generates and comprises the code of the secret information corresponding with the article of process object as second code; The string data generation unit is carried out computing, by this computing second code is converted to the code that does not expose secret information, and generates string data according to the code that obtains by this computing.
According to aforesaid way, in second code, comprise the information that the supvr that has only article just can know, so the people beyond the supvr to obtain its information extremely difficult.Therefore, safety that can further strong second code.
(4) code judgement system is following system: will be on article or its adjunct the character string of the optical information code of mark and regulation as object, whether the content of judging this mark is correct, it comprises: storage unit, itself and the corresponding second code of storing of first code relatedly, wherein, first code is represented intrinsic content, second code is respectively at a plurality of regular article that are marked with the optical information code of representing first code, utilize the one group information relevant to generate with these article, and this second code comprises each article information of intrinsic content respectively in this group of information, the information that second code comprised is not included in the first code, and second code is converted to character string with optical information code mark by the conversion process of regulation; Input block, it is at any article, receives the input of string data of the content of the reading of data imported and expression character string, and wherein, reading of data is that the optical information code to mark on these article reads and handles resulting data; The code determining unit, it comes the retrieve stored unit with the reading of data that input block received as first code, determines the second code corresponding with this code; Judging unit, it judges whether to access the identical string data of string data that is received with input block when having generated the string data of tagged object by the conversion process of utilizing the determined second code of code determining unit to carry out; And the judged result output unit, whether correct the judged result of its output judging unit as the content of expressive notation information.
In the storage unit in above-mentioned code judgement system, can store all " one group of information " of each article, but be not limited to this, (content in the first code is according to each article and different parts also can to store each information that constitutes second code and the information that second code and first code are associated at least, for example, described key word information).
System according to said structure, when judging that regulation article or its appendicular tag content be whether correct, the user reads processing to the optical information code, thereby will input to system as its result's the reading of data and the string data of expression character string content.Thus, the work of code determining unit, thus come the retrieve stored unit based on the reading of data of being imported, determine second code thus.And then, carry out the judgment processing of judging unit and the output of judged result output unit and handle.
For example, the code that the judging unit utilization is determined by the code determining unit, carry out the same conversion process of processing that the string data generation unit with the mark disposal system carries out, and compare with the string data that generated with the string data that reading of data is imported.Because first code and second code have only one-to-one correspondence, can think that therefore the string data of coming according to determined second code conversion is regular string data.Therefore, if the string data that is transfused to is consistent with regular string data, then being judged as tag content is regular content, if two string datas are inconsistent, then being judged as tag content is the content of forging.
The processing that judging unit carries out is not limited to above-mentioned processing.For example, also can carry out following processing: when in the mark disposal system, preserving over the second code that generates and string data accordingly, the determined second code of code determining unit is sent to the mark disposal system, thereby request sends the corresponding characters string data, and checks string data that is sent out and the string data that is transfused to.
According to said system, the relatively regular string data that derives from the represented first code of optical information code and the string data of mark, accurately whether the judge mark content is correct thus.
Judge in the preferred mode of system at above-mentioned code that (5) input block constitutes the reading of data that reception sends from external device (ED) and the unit of string data.In addition, whether correct the judged result output unit constitute the unit that the external device (ED) that has sent described reading of data and string data is returned the content of expressive notation information.For example, this mode is applicable to by the system of communication networks such as the Internet reception from the access modes of external device (ED).
(6) then, Articla management system has following function: for management article, and the function of mark optical information code and the code that constitutes by character string on article or its adjunct; Whether correct judge content the function of the mark of each code, described Articla management system comprises: with same storage unit, first code generation unit, second code generation unit, optical information code generation unit, string data generation unit, the indexing unit of described mark disposal system, judge same input block, code determining unit, judging unit and the judged result output unit of system with code.
According to this Articla management system, the storage unit that can use in mark is handled is judged the data source of usefulness as code, so the memory resource of can avoiding waste.In addition, owing in same system, carry out the judgment processing of mark processing and code, therefore can further improve the reliability of judgement.
(7) in labeling method, carry out following each step: to each article, utilize the part in one group of information relevant respectively with these article, generate these article of expression the first code of intrinsic content, and generate the step of second code, wherein, second code comprises each article information of intrinsic content respectively in the message block, and the information that second code comprised is not included in the first code; Generate the step of the optical information code of expression first code; To the conversion process that second code is stipulated, generate the step of the string data of tagged object; At each article, mark is represented the optical information code of first code and the step of the character string that is made of string data respectively on these article or its adjunct, and wherein, string data is the data that generate according to second code.

Embodiment
Fig. 1 represents a structure example of Articla management system 1 of the present invention.
This Articla management system 1 by article (below, with products such as electronic units is that example describes) manufacturer manage, this Articla management system 1 is carried out following processing: annotation management code on the product of manufacturer's shipment, and accept visit by the user of internet purchases product, and judge product that this user has mark whether correct.In addition, the connector that is connected to the Internet in system is provided with fire wall 6.
In system, be provided with manufacturing intrinsic information management server 2 and judgement a plurality of printing stations 4 (for convenience, illustrating) with an example of server 3, the usefulness that serves as a mark device.Printing station 4 comprises based on the printing treatment of computing machine with end device 40 and the printing machine 41 that is connected to this end device 40.With in the end device 40, enroll program in each server 2,3 and printing treatment respectively in not shown CPU, wherein, this program is used to set Fig. 5 described later, various functions shown in Figure 7.
Fig. 2 represents the body surfaces of product 100 (in this example for microswitch) and sticks on the example that the label 101 on the packing 102 of this product 100 has carried out printing.Below, printed information is defined as 2 d code and character string describes.
2 d code is represented according to each product 100 and the information of different contents.Character string also with each product 100 the information of intrinsic content as information source.Particularly, generate character string, that is, information is encrypted, the information after encrypting is replaced into numeral or letter by following processing.This character string is brought into play the function of the sign that is used to discern regular product with 2 d code, therefore below this character string is called " cognizance code ".
In the example of Fig. 2, mark under 2 d code (below describe to be printed as example) has cognizance code (as an example, mark " 86Gy9hY2 ").Like this, by near printing cognizance code 2 d code, can prevent that the user is judged as cognizance code mistakenly with other character strings.But,, then also can leave the position printing cognizance code of 2 d code if can allow each user know the printing position of cognizance code fully.
Return Fig. 1, judge that whether correct receive expression via fire wall 6 from the employed equipment 7 of user (below be called " user terminal 7 ") with server 3 judges code requests for content (below be called " judgement is asked "), and carry out judgment processing according to its request.
In judging request, comprise the string data of reading of data and expression cognizance code, wherein, described reading of data is to handle the data that obtain by carrying out at the 2 d code on body surfaces that is printed on product 100 or the label 101 to read.Therefore, user terminal 7 except have with function that the Internet is connected, also need to possess the function that reads 2 d code.For example, the personal computer that is connected with code reader (not shown) that 2 d code is used or the mobile phone with shoot function etc. can be used as user terminal.About string data, utilize keyboard to wait to import and both can.
Judge with server 3 utilizations and be included in from reading of data and cognizance code in the judgement request of user terminal 7, judge whether they represent correct code, and its judged result (be the code of expression " OK " when being judged as correct code, be the code of expression " NG " when being judged as false code) is returned to user terminal 7.Utilization by with the information of making between the intrinsic information management server 2 of communicating by letter and obtaining, carry out this judgment processing.
Be provided with database in making intrinsic information management server 2 (below, slightly be called " management server 2 "), wherein, this database is used to accumulate the various information that generate when each product is made in storage.In accumulating canned data, except model for example, make lot number, product export numbering etc. and can determine inherently one group of information of each product (information that each product is given respectively inherently), the information of people's relevant manufacturing management such as identification number is taken in the identification number, the identification number of production line, the manufacturing that also comprise manufacturing day, factory, each information is stored in the database explicitly, wherein, the information of described relevant manufacturing management is not that each product is intrinsic, but a plurality of products are set jointly.Then, a series of information that is associated can be extracted or retrieve to the information (for example, the combination of model, manufacturing lot number, factory number) that can determine product inherently as key word information, from management server 2.Thus, can obtain in case of necessity and the manufacturing of each product or one group of relevant information of management.In addition, the information of the intrinsic content that each product is given the respectively combination that is not limited to model, makes lot number, factory number.As other examples, the information that each product is given inherently also is the product consecutive number sometimes, also sometimes also for making mark.In addition, when not carrying out bulk management, the combination of model and factory number can be used to make intrinsic information.
That is, the database in the management server 2 is equivalent to " storage unit " of first technical scheme, wherein, in this storage unit, stores the multiple information relevant with article relatedly, thereby can determine the one group information relevant with these article for each article.Below, should be called " manufacturing intrinsic information " for the determined one group of information of each product, the database of making in the intrinsic information management server 2 also correspondingly is called " making intrinsic information database (DB) ".
In this embodiment, for each product, extract the code in the source that becomes 2 d code or cognizance code based on the manufacturing intrinsic information corresponding with this product.Fig. 3 illustrates the example that this code extracts.
Fig. 3 is that the manufacturing intrinsic information with a product is schematically illustrated as rectangular figure.Wherein, at this product, the part suitable with the information of intrinsic content (below be referred to as " individual information ") marked with filling pattern.Especially, the individual information represented with oblique line of front end is above-mentioned key word information.This means,, this all that product had are made intrinsic information associate by a key word information.
In the example of Fig. 3, utilize the information of making the specified quantity that comprises key word information in the intrinsic information, generation becomes the code (below be referred to as " first code ") in the source of 2 d code, and utilize the information that is not included in this first code, generation becomes the code (below, be referred to as " second code ") in the source of cognizance code.In first code, when comprising key word information, also comprise the common information that is chosen as individual information X in advance.The part that does not mark with filling pattern in first code for example also can comprise and the information of making relevant trackability (traceability), and this can the information of reviewing be that manufacturer wants to outside information transmitted.In second code, comprise another common information that is chosen as individual information Y in advance.The part that does not mark with filling pattern in second code for example comprises the information that the identification number of making day, factory, the identification number of production line, the identification number that the people is taken in manufacturing etc. have only manufacturer to know.In addition, in other information of the object that is not selected as first code and second code, be included in the information (the processing moment in each step, the instrumentation value in when inspection, check result etc.) that produces in the manufacture process, this information that produces in manufacture process is that manufacturer forbids the secret information to external leaks.
For first code, utilize common coding method to be converted into 2 d code.On the other hand,, implement the conversion process of regulation, make it become the content that does not expose individual information Y for second code.For example encrypt, the code conversion after will encrypting then is a string data, and with this string data as cognizance code.For cognizance code in this generation, the few code of figure place of preference data row.For example, if the data of second code are handled the data rows that is converted into 62 systems by implementing ciphered compressed, then can reduce the figure place of data rows.
As mentioned above, in first code, second code, comprise the information of intrinsic content respectively for each product, therefore all represent the content that this product is intrinsic, each code has only one-to-one correspondence.Therefore, the combination of cognizance code that generates according to second code and the 2 d code that generates according to first code is also for each product and unique decision.In other words, the 2 d code of each product mark and the combination of cognizance code are only applicable to this product respectively, so the code of like combinations can not be applicable to other products.
According to aforesaid code structure, can be simply and determine the code forged exactly.For example, when having set the content of 2 d code carelessly, the first code reality that reads from this 2 d code does not exist, and makes the intrinsic information database even therefore retrieve by this first code, can't find the manufacturing intrinsic information corresponding with this code yet.Therefore, retrieve manufacturing intrinsic information database, can judge that by this processing this code is a counterfeit according to the reading of data of 2 d code.
In addition, when the 2 d code that duplicates regular product, and change or when having set cognizance code carelessly, though there be the manufacturing intrinsic information corresponding with the first code that reads from 2 d code, the cognizance code of being derived by the second code that generates according to this information can be not identical with the cognizance code of printing.Therefore, determine to make intrinsic information according to the reading of data of this 2 d code, and generate second code, afterwards according to this information, whether judgement is identical with the cognizance code of printing according to the cognizance code that this second code generates, and can judge thus whether the cognizance code of printing is counterfeit.
On the other hand, when directly having duplicated the combination of 2 d code and cognizance code, it itself is correct being judged as its combination.But the product with this combination is unique, and several users can not have the product of like combinations.Therefore, when combination, when having a plurality of judgement request simultaneously, can think that the counterfeit that is printed with its combined code goes on the market at same code.In addition, in order to prevent from directly to duplicate the regular combination of 2 d code and cognizance code, also consider to carry out following countermeasure in addition: the hologram sealing label (hologram seal) of pasting the expression certified products on certain in product 100, packing or label 101, or on label, print, or constitute label 101 with special material with special seal China ink (ink).
Then, in the example of Fig. 3, generate first code and second code according to different information respectively, but be not limited to this, shown in Fig. 4 (1), also can be between each code common sparing information.But,, need only be set at and be included in the second code about individual information Y.
In addition, shown in Fig. 4 (2), when having cut apart the manufacturing intrinsic information corresponding with physics mode, also can extract the information that is included in the first code and be included in information in the second code from different information sources with product.At this moment, if each information source is associated, then can determine the second code corresponding simply with first code by common key word information.
Fig. 5 illustrates function relevant with the printing treatment of code in the Articla management system 1 of Fig. 1.In management server 2, except being provided with above-mentioned manufacturing intrinsic information database 20, also be provided with receiving and transmitting part 21, make intrinsic information and read portion 22, Data Management Department 23 etc.Receiving and transmitting part 21 is used for carrying out message exchange with printing treatment with end device 40, makes intrinsic information and reads portion's 22 execution from making the processing that intrinsic information database 20 is read specific manufacturing intrinsic information.Data Management Department 23 from the management data of printing treatment with end device 40 receptions, upgrades pairing manufacturing intrinsic information according to receiving and transmitting part 21.
Printing treatment end device 40 (below, slightly be designated as " printing terminal 40 ") in, be provided with and make intrinsic information obtaining section 42, first code generating unit 43, second code generating unit 44,2 d code generating unit 45, cognizance code generating unit 46, printing control unit 47, management data sending part 48 etc.
Fig. 6 is illustrated in the flow process of run time version printing treatment in printing terminal 40 and the management server 2.Among the figure, with the step (ST) of the processing of the numeric representation of No. 100 sections printing terminal 40 sides, with the step of the processing of numeric representation management server 2 sides of No. 10 sections.In addition, the relation of the processing between the with dashed lines arrow indication device.
Below, according to the flow process of Fig. 6, the printing treatment of carrying out by various functions shown in Figure 5 is described.
At first, the manufacturing intrinsic information obtaining section 42 of printing terminal 40 receives the printing indication from not shown production control system, and request management server 2 sends the manufacturing intrinsic information (ST101) of the product of printing object.This transmission request for example utilizes Fig. 3, key word information shown in Figure 4 to determine to send the information of object.
In management server 2, receive the request of sending (ST11) by receiving and transmitting part 21, and read portion 22 by the manufacturing intrinsic information and read the manufacturing intrinsic information (ST12) of being asked.And then, by receiving and transmitting part 21 the manufacturing intrinsic information of being read is back to printing terminal 40.
The manufacturing intrinsic information (ST102) that the manufacturing intrinsic information obtaining section 42 of printing terminal 40 receives from management server 2, and provide it to first code generating unit 43 and second code generating unit 44.First code generating unit 43 is extracted the information of the specified quantity that comprises key word information and individual information X from make intrinsic information, and to these information according to the rules order arrange etc., thereby generate first code (ST103).Second code generating unit 44 is also extracted the information of the specified quantity that comprises individual information Y from make intrinsic information, and to these information according to the rules order arrange etc., thereby generate second code (ST104).
The first code that first code generating unit 43 is generated is provided for 2 d code generating unit 45.45 pairs of these first codes of 2 d code generating unit are encoded, thereby generate 2 d code (ST105).
The second code that second code generating unit 44 is generated is provided for cognizance code generating unit 46.Cognizance code generating unit 46 encryption rule is according to the rules changed this second code, thereby generates the cognizance code (ST106) that is made of string data.
Ensuing ST107 is the processing of being carried out by printing control unit 47 and printing machine 41 shown in Figure 1.Printing control unit 47 reads in 2 d code and the cognizance code that generates among ST105, the ST106, and they are offered printing machine 41.At this moment, the product 100 or the label 101 of printing object are sent to printing machine 41, and printing machine 41 will provide each code that comes to be printed on the printing object thing from printing control unit 47.
The first code that first code generating unit 43 is generated also is provided for management data sending part 48.When the code of printing object was output to printing machine 41, management data sending part 48 correspondingly sent to first code management server 2, as the management data (ST108) of the product that is used to determine finish printing.According to this ST108, at the processing end in printing terminal 40 sides of a product.
The receiving and transmitting part 21 of management server 2 is handed to Data Management Department 23 with its management data when receiving from management data that management data sending part 48 sends (ST13 is a "Yes").Intrinsic information database 20 is made in Data Management Department 23 retrievals, thereby determines the manufacturing intrinsic information (ST14) corresponding with management data.And then Data Management Department 13 carries out following processing: with the manufacturing intrinsic information of this this product of determining explicitly storage representation printed code information (for example, sticking the sign (flag) etc. of expression " printing treatment finishes ") (ST15).According to this ST15, also finish at the processing in management server 2 sides of a product.
In addition, the processing of printing in the terminal 40 is not limited to above-mentioned processing, also can be such flow process, that is, after the printing treatment of carrying out ST107, omit ST108 and get back to ST101.At this moment, printing terminal 40 can not send to management server 2 when every pair of product carries out printing treatment, and can be accumulated storage a plurality of management datas (information that printing treatment finishes) in advance and be sent to management server 2 in the lump at the management data of stipulating that will accumulate storage opportunity (timing) by management data sending part 48.In addition, in management server 2, a plurality of management datas are carried out the processing of ST14, ST15.
Fig. 7 illustrate with Articla management system 1 in code judge relevant function.In judging, be provided with server 3 reception from the judgement request acceptance division 31 of the judgement request of user terminal 7, be used for returning the judged result sending part 36 of judged result to user terminal 7.And then, also be provided with reading of data sending part 32, result acceptance division 33, cognizance code generating unit 34, judgment processing portion 35 etc.
In management server 2, be provided with first code obtaining section 24, second code generating unit 25, result sending part 26 etc.And then, participate in the Data Management Department 23 of printing treatment and make intrinsic information database 20 also being used for the code judgment processing.
Fig. 8 illustrates at the code judgment processing, the flow process of the processing of carrying out in judging with server 3 and management server 2.In this Fig. 8, judge step with the numeral of No. 200 sections, with the step of the processing of numeral management server 2 sides of No. 20 sections with the processing of server 3 sides.In addition, same with Fig. 6, the relation of the processing between with dashed lines arrow indication device.
Below, according to the flow process of Fig. 8, the judgment processing by various function executing shown in Figure 7 is described.
Judge that request correspondingly begins to judge the processing with server 3 sides with receiving from user terminal 7, wherein, described judgement request comprises the reading of data of representing 2 d code and the string data of cognizance code.Judge that request acceptance division 31 when receiving this request, individually extracts reading of data and cognizance code (ST201,202) respectively.In addition, below for convenience, the cognizance code that will extract from judge request is called " cognizance code (A) ".
The reading of data of 2 d code is handed to reading of data sending part 32, and is sent to management service 2 (ST203).The first code obtaining section 24 of management server 2 receive these reading of data and with it as first code, it is handed to Data Management Department 23 (ST21).
In Data Management Department 23, key word information contained in the first code that is provided is discerned, and retrieved manufacturing intrinsic information database 20 (ST22) according to this key word information.In the time can extracting the manufacturing intrinsic information corresponding by this retrieval with key word information, the further manufacturing intrinsic information that is relatively extracted and the one-piece construction of first code.Its result when first code and the counterpart in the manufacturing intrinsic information are in full accord (when ST23 is "Yes"), checks the information (ST24) that whether writes " printing treatment finishes " in the manufacturing intrinsic information that is extracted.
When failing to extract the manufacturing intrinsic information corresponding (when ST23 is "No") with first code, though perhaps extracted corresponding information, but when it makes the information that does not write " printing treatment finishes " in the intrinsic information (when ST24 is "No"), Data Management Department 23 gets in touch with result sending part 26, makes result sending part 26 will represent that the code of " NG " sends to judgement server 3 (ST27).
On the other hand, when extraction comprises the manufacturing intrinsic information of the content identical with first code and write the information of " printing treatment finishes " in this information (as ST23, when ST24 is "Yes"), Data Management Department 23 should make intrinsic information and offer second code generating unit 25.Second code generating unit 25 generates second code (ST25) based on the rule same with the second code generating unit 44 of printing terminal 40 sides according to the manufacturing intrinsic information that is provided.Result sending part 26 sends to this second code to be judged with server 3 (ST26).
Finish to above-mentioned ST26 or ST27 at the processing that sends reading of data from judgement with server 3 in management server 2 sides.The data that sent are read into the result acceptance division of judging with server 3 33.
When result acceptance division 33 receives from second code that management server 2 sends (when ST204 is "Yes"), this second code is provided for cognizance code generating unit 34.Cognizance code generating unit 34 is encrypted second code, thereby is generated cognizance code (ST205) based on the encryption rule identical with the cognizance code generating unit 46 of printing terminal 40 sides.Below, the cognizance code that the second code that is used to from this management server 2 is generated is called " cognizance code (B) ".
Cognizance code (A) that is extracted by judgement request acceptance division 31 and the cognizance code (B) that is generated by cognizance code generating unit 34 are read in judgment processing portion 35, and both (ST206) are checked.Check by this, when two codes are consistent (when ST207 is "Yes"), judgment processing portion 35 provides the code of " OK " to judged result sending part 36, and makes judged result sending part 36 send it to user terminal 7 (ST208).On the other hand, when two codes are inconsistent (when ST207 is "No"), judgment processing portion 35 provides the code of " NG " to judged result sending part 36, and makes judged result sending part 36 send it to user terminal 7 (ST209).
On the other hand, when result acceptance division 33 be not to receive 2 d code but when receiving the code of " NG " (when ST204 is "No"), this code is handed to judgment processing portion 35.The judgment processing portion 35 of this moment does not carry out collation process, and provides the code of " NG " to judged result sending part 36, and makes judged result sending part 36 send this code (ST209).
When the transmission processing of ST208 or ST209 finished, the judged result that judgment processing portion 35 will send and various information relevant with this judgement (reading of data, cognizance code (A) (B) etc.) were saved in (ST210) in the not shown storer together.Handle according to this, finish at judgement processing of request from user terminal 7.
In addition; in the example of above-mentioned Fig. 7, Fig. 8; at the transmission of using the reading of data of server 3 from judgement; send second code from management server 2; but for the safeguard protection that makes second code becomes perfectly safe; also can set the systematic function of cognizance code in management server 2 sides, and correspondingly return cognizance code (B) with the processing that sends reading of data.
According to a series of processing shown in Figure 8, if judge that the product of object is regular product, then the cognizance code (A) that extracts from judge request must be consistent with the cognizance code that generates according to the second code from management server 2 (B), at judging request, send the judged result of " OK ".
On the other hand, when the product of judging object is a counterfeit, when a certain product duplicated 2 d code and rewritten cognizance code carelessly, cognizance code (A) and cognizance code (B) were inconsistent, to the judged result of user terminal 7 transmissions " NG ".
In addition, though the situation that exists 2 d code to be forged under general situation, can think that the manufacturing intrinsic information corresponding with the 2 d code of forging do not exist.Therefore,, can't extract corresponding information, return the code of " NG ", user terminal 7 also be sent the judged result of " NG " in management server 2 sides at from judging the reading of data of sending with server 3.In addition, even exist once in a while and the corresponding manufacturing intrinsic information of forging of 2 d code, be kept at and make in the intrinsic management server 2 owing to make in the second code in intrinsic information contained individual information Y, can think that therefore the possibility that the third party obtains this individual information Y and derive correct cognizance code exists hardly at it.Therefore, same with the situation that cognizance code is forged, be in cognizance code (A) and the inconsistent state of cognizance code (B), therefore user terminal 7 is still sent " NG ".
Like this, according to the judgment processing of said system, can be simply and judge exactly whether code is correct.
In addition, be provided with two servers 2,3 in above-mentioned Articla management system 1, management server 2 participates in the processing of two kinds of codes of printing and judges these two kinds of processing of processing that printed code is whether correct, but also server 2,3 can be made of one.
In addition, also can be substituted in and carry out two kinds of processing in the same system, and come piece-rate system according to contents processing.At this moment,, then also can send first, second code of each product that finishes printing to the system of judging side, and they are accumulated be stored in the system of judging side from the system of printing treatment side if can guarantee the safety of second code.At this moment, the system of judging side has " storage unit; in this storage unit; respectively at a plurality of regular article that are marked with the optical information code of representing first code; store second code accordingly with first code; wherein; described first code is represented intrinsic content, described second code is to utilize the one group information relevant with these article to generate, and described second code comprises each article information of intrinsic content respectively in this group of information, the information that described second code comprised is not included in the first code, and described second code is to be converted to the character string that is labeled with the optical information code by the conversion process of stipulating ".
In addition, above-mentioned Articla management system 1 with electronic unit as object, but also can construct system to the article (brand-name goods, credit card etc.) beyond the electronic unit with spline structure.At this moment, according to different article, also can there be the situation that as the situation of electronic unit, does not produce various individual information, but, for example, by generating a plurality of random numbers and making up their method, can generate the information of intrinsic content to each article respectively, and use their individual information Y as second code.
In addition, in the above-described embodiments,, all in management server 2, manage, but, also can duplicate and preserve in the position beyond the management server 2 for the information that constitutes first code for making intrinsic information.For example, if the printing object thing is large item, then also can in storage mediums such as RFID label and with it, be attached on the printing object thing, thereby in the way of printing machine derivation, reading first code for the information stores that each article will constitute first code.
