Description
Technical field
The present invention relates to commerce and trade, electronics, communication, software and encode false-proof technical field.
Background technology
Manufacturing and marketing the fake are rampant, and fake and forged commodity is spread unchecked, and the economic order of seriously disrupting the market had both been encroached on the manufacturer's interests of abiding by the law, and also damaged mass consumption person's rights and interests.Why the cigarette of personation, drinks, tealeaves, medicine, seed, chemical fertilizer etc. remain incessant after repeated prohibition, and except supervising vacant reason, key still lacks effective anti-counterfeiting technology means.At present anti-counterfeiting technology commonly used mainly contains: material is false proof, package anti-counterfeiting, antiforge, laser anti-counterfeit, electronic anti-fogery, texture anti-fake, safety line is false proof, mobile phone short message is false proof etc.They are owing to the restriction effect of technology or cost is limited, and the personation phenomenon still emerges in an endless stream.In fact, mobile phone short message Anti-fake digital label just is easy to cheapness and has bought on market.Bar codes technique develops into two-dimension code from simple one dimension code, and has formed multiple two-dimensional bar code standard, such as code systems such as QR code (Quick Response Code), DM codes (Data Matrix).Recently two-dimensional bar code is gradually as the anti-counterfeiting mark of the ticket such as invoice, ticket and article, but it generates with authentication scheme and have defective, also depends on the sealing algorithm, and the bar code capacity is little and be not enough to contain necessary authentication information." digital bar code watermark and method for anti-counterfeit " (Chinese invention patent application number 02110959.1, announced and recalled), proposition embeds two-dimensional bar code with bulk information as watermark, in bar code, note down digital signature or the enciphered data of its corresponding informance by public key algorithm, encrypt or the signature private key, deciphering or checking PKI are to realize the bar code digital anti-counterfeiting." based on the two-dimensional bar code automatically identifying and reading method of general office equipment " (Chinese invention patent 03114568.X, stopped right), solve the bar code image automatic recognition problem by Wiener filtering, minute block correction and Threshold segmentation, and the large information capacity data compression such as comparison film is proposed in two-dimensional bar code, undertaken false proof and encrypt by digital signature." a kind of false proof bill, bill anti-counterfeit method and system " (Chinese invention patent number 03137393.3), proposition is extracted the unique identification characteristics of image to the original document image and is carried out digital signature, digital signature information is encoded to two-dimensional bar code, and the original document image consists of false proof bill together." based on article antifake true information and the signature verification device of digital signature " (Chinese invention patent application number 200510021702.9), also propose signer and with private key the Item Information coding is carried out digital signature, the verifier uses public-key proves the digital signature that embeds the article information coding whether sign by signer.The problem that art methods also need solve comprises, the one, and the differentiation of the similar a large amount of individualities of object (product, commodity, certificate, bill etc.) is differentiated; The 2nd, signature is acted as fraudulent substitute for a person in prevention during general discriminating; The 3rd, differentiate the convenient practical of service.
Summary of the invention
The present invention proposes a kind of two-dimensional bar code method for anti-counterfeit, is used for making false proof two-dimensional bar code label, appends on object or the wrappage, to reach false proof purpose.The general objectives thing has specific attribute information, and for example, product has the information such as its title, brand, trade mark, the place of production, date of manufacture, the term of validity, manufacturer.With the attribute information of object one-tenth text-string arranged sequentially, private key with signer is made the numeral signature to text character string, obtain the byte sequence data of digital signature, again these byte sequence data are made visual coding (for example adopting the BASE64 algorithm), namely obtained the text character string data of digital signature.The Digital Signature Algorithm here is actual to comprise two steps, first with object attribute information text-string, the hashing algorithm by standard (hash algorithm, such as MD5, SHA-1 etc.), calculate hashed value (summary); Then use the private key of signer, by asymmetric cryptographic algorithm (such as RSA, DSA etc.) the keyed hash value of standard, the gained encrypt data is digital signature; Same algorithm is also adopted in checking, but comes certifying digital signature with the PKI of signer.With the attribute information text-string of object, together with to one of the digital signature text-string of this attribute information, coding becomes patterned two-dimensional bar code, prints or prints and namely make the two-dimensional bar code antifalsification label.The digital signature text-string is formatd, for example added special delimiter at head and the tail, in order to distinguish isolation with object attribute information text-string.In order to make the process universalization of certifying digital signature, digital certificate (public key certificate) numbering is also placed in the two-dimensional bar code as key word, specifically can be positioned over ad-hoc location in the object attribute information, but be placed on more convenient nature in the digital signature formatted message text-string.Extract this key word and can be used for certifying digital signature by the key numbers certificate.Because the attribute information of object all is common for all individualities of class object of the same race usually, the digital signature that therefore generates is all identical, and the label of making is also the same.In order to distinguish each individuality, accomplish one yard of a thing, introduce especially barcode number that a standard increases progressively as tag number, to guarantee that the two-dimensional bar code label has unicity and namely do not repeat.Such tag number is standard why, and just being to work out has the Unified coding form, is totally independent of the attribute information of object, and automatically increases progressively numbering.Even the object of some kind itself also has certain numbering of oneself, also to add unified barcode number.This means, allow different types of object two-dimension code label, all use the tag number of unified standard.Can't avoid the two-dimensional bar code label to be forged in view of only increasing tag number, the barcode number that just standard is increased progressively is also included the information content scope that digital signature covers in the two-dimensional bar code in, namely with barcode number together with one of object attribute information, calculate digital signature.Like this, the true and false of barcode number also becomes identifiable.Just because of barcode number is included into the digital signature scope, as long as the private key of signer is not revealed, others will fabricate a new numbering two-dimensional bar code label that belongs to signer is fully infeasible.So the two-dimensional bar code label information namely is comprised of three parts: the attribute information of the barcode number that a standard increases progressively (being tag number), object, and the digital signature that covers front two parts information.
Encode management and examination service for the ease of the two-dimensional bar code label in the barcode number form that standard increases progressively, comprise for the digital composition of distinguishing the object kind it.For example, manufacturer may produce multiple product, just can tell one section in the barcode number form and identify product category, and another section is then as the serial number under this kind.In the two-dimensional bar code label information, it is more appropriate that the barcode number setting is positioned at first trip, and convenient the parsing identified.When making the two-dimensional bar code label, barcode number can be printed near the outside, edge of two-dimensional bar code figure, so that the two-dimensional bar code label is distinguished and quoted to vision.
The present invention also proposes a kind of two-dimensional bar code label checking method.The digital certificate numbering is placed in the two-dimensional bar code, when bringing examination two-dimensional bar code label universalization benefit, also stays the risk that counterfeit digital signature occurs.For example, the Product labelling of first has the digital signature of first, and second can be removed the digital signature of first and change by oneself signature replacement.In this case, just extract wherein digital certificate numbering retrieval PKI and verify that the result will pass through, and can not find that digital signature is stolen the beams and changed the pillars.Solution is in proof procedure, and possessor's title of digital certificate that will the retrieval gained compares with signer title in the object attribute information, just can draw correct judgement.For this reason, the object attribute information is made such layout: the front standard that connects increases progressively barcode number, after connect digital signature; And in the object attribute information, the setting of signer title is positioned at last column, and visually also representing attribute information before is responsible for, the while is delegation before the formatted message of digital signature again.The comparison of described title namely automatically performs according to this location.On the other hand, although new two-dimensional bar code label can't be forged, ready-made label may be replicated and falsely use.This needs systematized restriction solution, exactly in checking correct (being that digital signature is effective and the signer title is consistent) afterwards, preservation is to the examination record of look into numbering two-dimensional bar code label, and each examination all will check with numbering two-dimensional bar code label whether once checked before this, repeat examination thereby repel.If authentication error, namely label is invalid, then need not keep the examination record.Duplicate examination and mean that discovery has vacation, only same examination person heavily detects feelings.Consider in the reality, may need repeatedly rationally to check to the two-dimensional bar code label.For example, commodity may need through sole distributor, retail trader, retailer, consumer in the circulation sale link, and every one-level is all differentiated commodity true and false by the examination label possibly.Solution, be with examination person by Role Classification (such as classification), examination record then contrasts examination person's the corresponding book of final entry of role; For similar examination person (such as being all the consumer), the examination of repetition is repelled mutually, and for non-similar examination person (such as retailer and consumer), the examination of repetition is allowed mutually.
The present invention also proposes the method for servicing of a kind of two-dimensional bar code label examination, so that the discriminating of two-dimensional bar code label is served is convenient practical.Set up service center in the market, come to read the two-dimensional bar code label information for client provides the service of checking commodity true and false with barcode scanner identification with the examination terminal, be committed to a believable service system and differentiate and obtain the examination result.Scale and form are regardless of in said market, and be little of retail shop, in to shops, arrive greatly supermarket, logistic storage, wholesale distribution centre etc.Each time examination, all need to be initiated a message to service system with mobile phone by client and could obtain the examination result, service system is then obtained client's phone number by receiving mobile phone information, identify examination person with this phone number, and preserve one the two-dimensional bar code tag number of the looking into examination record of phone number association therewith.
Require client with mobile phone to the basic purpose that service system initiates a message, be to identify examination person in order to allow service system obtain client's phone number, with preservation the two-dimensional bar code tag number of the being looked into examination record related with phone number.In addition, also lay a good foundation for service charge, for example SMS receiving information service expense.Client initiates a message to service system with mobile phone, divides again following several situation:
The first situation, the two-dimensional bar code label information is read in barcode scanner identification, sent on client's mobile phone by the Bluetooth communication mode by the examination terminal, client sets up first with the bluetooth of checking terminal with mobile phone and is connected reception, then just label information is sent as message and submits to service system to differentiate.This shows as a kind of self-help service, may cause when avoiding many people to operate to send and obscure, a kind of way, be first mobile phone with check set up between the terminal bluetooth be connected after scanning two-dimension bar code label again; Another kind of way, to input the two-dimensional bar code tag number and send to the examination terminal at mobile phone in advance by client, then check terminal and determine corresponding source address mobile phone according to receiving the two-dimensional bar code tag number, the destination address that is re-used as sends the two-dimensional bar code label information to this mobile phone.
Second case is client with mobile phone send two-dimensional bar code tag number and examination terminal code the two one of or send simultaneously the two.If what send is the two-dimensional bar code tag number, then service system after receiving the two-dimensional bar code label information that the examination terminal is submitted to, namely directly set up related between the tag number of looking into and the phone number; If what send is examination terminal code, the examination terminal code that connects by receiving the two-dimensional bar code label information of service system then, and indirectly set up related between the tag number of looking into and the phone number.The association of setting up thus, the message of service system feedback both can directly be exactly to check result's (namely sending the examination result to corresponding mobile phone), also can be the notice that the examination result sends to the examination terminal.
The third situation is that the client sends a reservation message with mobile phone, and service system is fed back an identifying code (perhaps being other title), by with this identifying code input examination terminal, submits in the lump service system to differentiate by the examination terminal together with the two-dimensional bar code label information.Service system again with this identifying code as key word, ask for the phone number of this identifying code before retrieving, thus set up the therewith association between the phone number of the two-dimensional bar code tag number of looking into.Can also comprise subscription information in the reservation message that mobile phone sends, obtain examination result's context and/or receive the destination from service system with agreement.For example, the option of subscription content scope is only asked for identifying code, is wanted identifying code also will check the result, examination comprises object attribute information etc. among the result.And for example subscribing the examination result and receive the destination, is mobile phone or examination terminal.
Rear two kinds of situations all need to submit to service system to differentiate the two-dimensional bar code label information by the examination terminal, so be considered as the service of assistance formula.
Under various situations, service system can both be known client's phone number, and it is sent the examination result to corresponding mobile phone as destination address.So the two-dimensional bar code label information is after service system is differentiated, gained examination result can have three kinds of obtain manners: the one, and send to the examination terminal and show, the 2nd, directly send to client's mobile phone, the 3rd, both send to the examination terminal and also sent to client's mobile phone.
Good effect of the present invention, the one, propose standard and increase progressively barcode number, both be widely used in making the two-dimensional bar code antifalsification label into various object, also efficiently solve a large amount of individual differentiations of similar object and differentiate; The 2nd, signer title automatic comparison mechanism is proposed, can effectively prevent the signature of acting as fraudulent substitute for a person under the general discrimination condition, also satisfy and press the rationally needs of examination of examination person's different role classification; The 3rd, the method for servicing of the two-dimensional bar code label examination of the convenient practicality of proposition bases oneself upon the market provides the examination commodity true and false at any time for client service.The invention provides effective method for anti-counterfeit and service mode, it puts into practice, is expected effectively to check the manufacturing and marketing the fake lawbreaking activities, safeguards numerous manufacturers and consumers in general's rights and interests.
