In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upperTechnical solution is stated to be described in detail.
Referring to Figure 1, the embodiment of the present invention provides a kind of product traceability method, and this method can be applied to shown in Fig. 2Product traceability system, as shown in Fig. 2, the product traceability system may include the CA (certificate for providing product digital certificateProviding gear) and the corresponding manufacturer's terminal of product producer, circulation quotient terminal corresponding with product stream trading, disappear with productThe corresponding consumer end of expense person and cloud are traced to the source platform.The process of this method is described as follows.
Step 11: manufacturer's terminal wants original production by manufacturer's digital certificate, with the private key of manufacturer's digital certificatePrime information carries out in the original production factors information write-in NFC label of encryption of encryption acquisition, and will encrypt original production factors letterBreath and the NFC label identification information of NFC label are sent to cloud platform of tracing to the source and make cloud platform of tracing to the source that will encrypt original productionElement information and NFC label identification information associated storage；Wherein, NFC label is set at the packaging opening of product.
Each manufacturer can belong to the digital certificate of the manufacturer to CA application, such as by manufacturer to CA applicationDigital certificate is referred to as manufacturer's digital certificate, and manufacturer's digital certificate can be used to prove the legal identity of manufacturer.It is obtainingAfter manufacturer's digital certificate, manufacturer can be collected the private key of manufacturer's digital certificate to pass through private key to some specific lettersBreath carries out ciphering signature, in addition can be open to masses by the public key of manufacturer's digital certificate.
Product producer can obtain the original production factors information of the product during producing product, productOriginal production factors information may include the place of production of product, manufacturer, date of manufacture, production batch, filling position, bottle placerType number etc. all information relevant to the product is produced, can be known related to production by production factors informationThe case where.
Product producer can use the private of manufacturer's digital certificate after obtaining the original production factors information of productKey encrypts the original production factors information of product to obtain the original production factors information of encryption and (referred to as encrypt original lifeProduce element information), the original production factors information quilt of product can be prevented as far as possible by the private key encryption of manufacturer's digital certificateIt distorts, to ensure the safety of original production factors information, prevents from being stolen as far as possible usurping, and can also be true by private key encryptionGuarantor must be encrypted by the legal manufacturer of product, because only that the legal manufacturer of product just possesses the private key of product.?In specific implementation process, original production factors information can be added with scheduled Encryption Algorithm by manufacturer's digital certificateClose processing can use specific Encryption Algorithm the Encryption Algorithm in existing, just be not explained in detail herein.
Further, product producer can use manufacturer's terminal (such as NFC read-write equipment) and demonstrate,prove manufacturer's numberBook and the original production factors information of encryption are written in NFC label together, and manufacturer's digital certificate includes corresponding public key.It will give birth toBusiness men digital certificate is written in NFC label can be in order to which subsequent such as circulation quotient scans NFC label by terminal directly to obtainMust circulate manufacturer's digital certificate, and then can use the public key of manufacturer's digital certificate and encrypt to circulation information etc.Reason, that is to say, that raw manufacturer will be the equal of by manufacturer's digital certificate by the way that manufacturer's digital certificate to be written in NFC labelAnd its public key is disclosed to circulation quotient.
NFC label is arranged at the packaging opening of product in the embodiment of the present invention, by taking wine as an example, NFC label can be setThe sealing part in the external packing box of wine is set, just needs to tear to pieces NFC label when the external packing box of wine to be opened, the NFC mark torn to piecesLabel are just discarded to be reused, and can reapply counterfeit production on other packing boxes in this way to avoid the NFC label that will be tornProduct, or NFC label can also be arranged in the bottle cap of bottle and the joining place of bottleneck, elder generation is just needed when consumer is using wineIt tears to pieces NFC label and could open wine lid and pour out wine, in this way also for avoiding the NFC label that will be torn from reapplying other bottlesUpper progress is counterfeit.That is, NFC label can be regarded as disposably, the corresponding NFC label after product useIt just fails, the NFC label progress that can be avoided passing through as far as possible on used product in this way is counterfeit.In addition, NFC label can be withBe before product export by manufacturer by printing, the modes such as paste or inlay and be fixed at the packaging of product and seal offPlace, may insure that product has just posted NFC label before coming into the market in this way.
In the specific implementation process, dedicated reader, which can be used, in manufacturer will need to be stored in the letter in NFC labelIn breath write-in NFC label, or the terminal device with NFC function also can be used, relevant information, example is written to NFC labelAs manufacturer can configure the dedicated terminal device (such as mobile phone) for having NFC function that letter is written into NFC labelBreath reads information from NFC label.
NFC technique is the non-contact radio-frequency identification and interconnection technique between being derived from wireless device, not only have it is non-contact,The characteristics such as unique identification, read-write, have been developed the wireless communication protocol of oneself, completely compatible RFID label tag, meanwhile, NFC is notThe read-write equipment dedicated, expensive using such as RFID is needed, buying and use cost can be greatly reduced, allows for big modelThe promotion and popularization enclosed, and all there is in most of mobile phone terminals NFC function at present, consumer can directly utilize useMobile phone scan NFC label directly under the premise of any software additionally not being installed to obtain the information being written in NFC label, thisIt can also be in favor of the popularization and realization of scheme.
Meanwhile product producer can also will encrypt original production factors information and NFC label identification information (such as NFCThe ID of label) it is uploaded to cloud together traces to the source platform, platform is traced to the source in cloud can be by both after receiving these informationInformation is associated storage.The side of transimission and storage after being encrypted by manufacturer's digital certificate to original production factors informationFormula can ensure that original production factors information is not distorted during transimission and storage by criminal as far as possible and steal, to protect as far as possibleThe safety of production information is demonstrate,proved, reduces product from the root by counterfeit possibility
Also, original production factors information will be encrypted and NFC label identification information is associated storage, then making subsequentWith in the process, as long as finding the corresponding original production factors information of encryption by NFC label identification information.Because logicalIt is more to cross the cloud information that platform is stored of tracing to the source, in order to ensure the accuracy of each product corresponding informance, it is possible to pass throughThe mode that NFC label identification information is associated storage encrypts original production factors information to the product and is associated storage.NoOnly in this way, as long as all relevant informations of the subsequently received product, can use such and NFC label identification informationThe mode of associated storage is stored, so facilitate it is subsequent relevant information directly found by NFC label identification information,That is, it is possible to regard NFC label identification information as the lookup of relevant information index, the standard of information searching may insure in this wayTrue property and quick search.
In addition, cloud is traced to the source, platform directly can find production quotient corresponding with NFC label identification information from cloudWord certificate, and manufacturer's digital certificate can be manufacturer and just be uploaded to cloud after obtaining to CA application and traces to the source platform, or be also possible to cloud trace to the source platform directly from CA management organization inquiry obtain, etc..Further, it is needing to adjustWhen with original production factors information, platform is traced to the source in cloud can be with the private key of manufacturer's digital certificate to the original life of the encryption of storageIt produces element information to be decrypted to obtain original production factors information, and then completes subsequent operation.
Step 12: circulation quotient's terminal reading NFC label, will to obtain manufacturer's digital certificate and NFC label identification informationIt is write with the original circulation element information of encryption that the public key of manufacturer's digital certificate carries out encryption acquisition to original circulation element informationEnter in NFC label, and will encrypt original circulation element information and NFC label identification information is sent to cloud platform of tracing to the source and makesCloud platform of tracing to the source will encrypt original circulation element information and NFC label identification information associated storage.
After factory, product may just reach at consumer by certain circulation, when products in circulation to the quotient that circulatesWhen place, circulation quotient can obtain products in circulation to the factor of circulation information at this, and the quotient that circulates can be used terminal device and (such as claimMake circulation quotient's terminal) the factor of circulation information of automatic collection product, such as current date and locating can be detected by mobile phonePosition, etc., or these information, etc. can also be manually entered by the quotient that circulates.Wherein, the original circulation element information of productMay include circulation information acquisition the date, the picker of circulation information, circulation information acquisition position, product storage positionIt sets, environmental information, the current circulation quotient's rank etc. of product storage, that is to say, that the factor of circulation information of product is and productionThe relevant information of product current intelligence.It for ease of description, will be by the stream of legal circulation the acquired acquisition of quotient in the embodiment of the present inventionLogical element information is referred to as original circulation element information.
Due to may can be used for every level-one circulation quotient by one or more levels circulation in actual circulationAbove-mentioned mode, which acquires, obtains products in circulation to current factor of circulation information, by all circulation quotient to every grade of current intelligenceBulk registration can then obtain product from factory to the complete current intelligence eventually arrived at from consumer.
In addition, the current quotient that circulates can be by by reading at product packaging opening when products in circulation to current somewhereNFC label to obtain manufacturer's digital certificate and NFC label identification information, and then again with the public affairs of manufacturer's digital certificateKey encrypts to obtain and encrypt original circulation element information original circulation element information obtained, further again will encryptionIn original circulation element information write-in NFC label, and will encrypt original circulation element information and NFC label identification information together onCloud is reached to trace to the source platform, cloud trace to the source platform receive the original circulation element information of encryption that circulation quotient's terminal uploads withAfter NFC label identification information, both information can be associated to storage.By manufacturer's digital certificate to original circulationThe mode of transimission and storage can ensure original circulation element information in transimission and storage mistake as far as possible after element information is encryptedIt is not distorted and steals by criminal in journey, to guarantee the safety of circulation information as far as possible, reduce product from the root by counterfeitIt may.
It is understood that every level-one circulation commercial city can be by the original of commodity circulation to this place if there is multilevel flow is had trade relationsBeginning factor of circulation information, which is associated with after encryption with NFC label identification information, to be uploaded to cloud and traces to the source platform, by different levelsIt circulates the accumulative upload of quotient, cloud platform of tracing to the source can obtain complete circulation path situation of the product in the entire process of circulation.
Step 13: consumer end read NFC label with obtain NFC label identification information, encryption production factors information andFactor of circulation information is encrypted, and production factors information and encryption factor of circulation information will be encrypted together with NFC label identification informationCloud is sent to trace to the source platform.
After factory, the product for being provided with NFC label above-mentioned can circulate product on the market, consume when being circulated toWhen at person, whether consumer may be that certified products carries out verifying of tracing to the source to the product, and consumer's end can be used in consumer at this timeThe NFC label being arranged on the directly scanning product of end (such as mobile phone with NFC function) is to read NFC label identification information, addDense production element information and encryption factor of circulation information, and these information associations that scanning obtains are uploaded to by cloud by mobile phoneEnd is traced to the source platform, and then to carry out identification of tracing to the source by cloud platform of tracing to the source come the true and false to product.
Because the product is likely to be counterfeit, if counterfeit, the encryption information stored in NFC label mayIt is not just that the original production factors information of encryption that legal manufacturer is written when product export and legal circulation quotient pass through in streamThe original circulation element information of the encryption being written in journey, but palm off the encryption that quotient copies legal manufacturer and legal circulation quotient write-inInformation, then what consumer read by consumer end's scanning is not naturally also just really to encrypt original production factors to believeIt ceases and encrypts original circulation element information, so with " encryption production factors information " and " adding in order to distinguish in the embodiment of the present inventionClose original production factors information " distinguishes come the information for scanning manufacturer's write-in read and legal to consumer end, withAnd to scan consumer end with " encryption factor of circulation information " and " encrypting original circulation element information " reading and legalThe information of circulation quotient's write-in distinguishes.
Step 14: cloud trace to the source platform manufacturer's digital certificate public key respectively to encryption production factors information and encryptionThe decryption of original production factors information is to obtain production factors information and original production factors information, and with manufacturer's digital certificatePrivate key to encryption factor of circulation information and encrypt the decryption of original circulation element information respectively to obtain factor of circulation information and originalBeginning factor of circulation information, and by production factors information and factor of circulation information respectively with corresponding original production factors information and originalBeginning factor of circulation information carries out matching and compares the true and false to determine product according to matching result and produce current intelligence.
Cloud trace to the source platform receive consumer upload NFC label identification information, encryption production factors information and addAfter close factor of circulation information, corresponding manufacturer's digital certificate can be found first with NFC label identification information, then with lifeThe encryption production factors information to consumer end's upload and the encryption stored before are original respectively for the public key of business men digital certificateProduction factors information is decrypted to obtain production factors information and original production factors information, and the private with manufacturer's digital certificateKey respectively decrypt by the encryption factor of circulation information to consumer end's upload and the original circulation element information of encryption stored beforeTo obtain factor of circulation information and original circulation element information, that is to say, that the production factors information of encryption with public key decryptions,And the factor of circulation information of encryption is decrypted with private key.
Further, then by the production factors information of decryption acquisition and original production factors information matching comparison is carried out, withAnd the factor of circulation information of decryption acquisition and original circulation element information are subjected to matching comparison, further according to final matching resultDetermine the true and false and production current intelligence of product.
When two kinds of production factors information are compared with two kinds of factor of circulation information respectively, it is understood that there may be different ratiosCompared with as a result, in order to facilitate the understanding of those skilled in the art, explanation is introduced to some possible situations below.
If it is certified products, platform is traced to the source in cloud can be using the public key of manufacturer's digital certificate successfully to consumer's endThe encryption production factors information that end uploads is decrypted, then the production factors information and original production factors of decryption obtainedInformation is just consistent.
If it is fake products, since personation quotient is unaware of and cloud is traced to the source the cipher mode arranged between platform, soPlatform is traced to the source in cloud also just can not be to the encryption production factors letter that consumer end uploads by the public key of manufacturer's digital certificateBreath is decrypted, then final decrypted result obtained may be exactly messy code or can not decrypt, so finally obtaining at allDecryption production factors information and original production factors information naturally also just mismatch.
If it is fake products, palm off quotient may also be obtained by certain approach manufacturer's digital certificate private key andProduction information is encrypted also by the private key of manufacturer's digital certificate, but since it is personation, then what it was obtainedPalm off production factors information and legal manufacturer original production factors information be also certainly it is different, so cloud trace to the source it is flatEven if after the encryption production factors information successful decryption that the private key that platform passes through manufacturer's digital certificate uploads consumer end,The production factors information of decryption obtained and original production factors information are also unmatched.
As described above, if fruit product is certified products, then the production factors information and original production factors information decrypted are exactlyThe same, it naturally also just matches, matching result at this time shows that product is certified products.If fruit product is counterfeit merchandise, then decryptingProduction factors information otherwise due to decoding error obtain messy code or due to decoding failure or script encryption production factorsInformation or even if the production factors information for the decryption that successful decryption is obtained and original production factors information have differences, totalFor, the production factors information of decryption and original production factors information be it is unmatched, identification result at this time shows that product isNon- certified products.
Matching explanation has been carried out just for production factors information above, has been also according to identical for factor of circulation informationMode understands, i.e., if matching result unanimously if show circulation information be it is true, the stream of product can be truly reflected outUnderstanding and considerate condition, such as circulation quotient's title and specific circulation path etc. show that circulation exists if matching result is inconsistent and askTopic.
No matter identification result why, which can be fed back to consumer end by cloud platform of tracing to the source, so as toIn consumer can by check mobile phone directly know authenticity of products verifying trace to the source result and production current intelligence.If it is determined thatProduct is certified products, can make consumer's product safe to use, if it is determined that product is non-certified products, can by mobile phone directly toRelative alarm platform is reported, such as directly sends report message to 12315 platforms.Such as, if it is determined that factor of circulation letterBreath be it is non-true, then can then determine that the product is obtained by informal channel even illegal channels, at this time thenThe product can be not enough bought, and at the same time can also be reported to relevant departments.In the embodiment of the present invention, by producing quotientThe mode that word certificate carries out encrypting and decrypting to the production of product and factor of circulation information not only can know product in order to consumerTrue current intelligence to ensure the production of product and the safety of factor of circulation information, can also be in customer consumption productUser increases certain interest, the purchased probability of larger production.
Also, if fruit product is certified products, platform is traced to the source in cloud can also be by production factors information (the i.e. original production of decryptionElement information) and decryption factor of circulation information (i.e. original circulation element information) be sent to consumer end, in order to consumePerson can view the product original production factors information and original circulation element information, to the condition of production and circulation of productThere is a rough understanding, enables consumers to the entire process of circulation for intuitively understanding product, and can also knowComplete circulation element information of the product at every grade of circulation quotient, can make the process of circulation of product transparent in this wayChange, can also be supervised to a certain extent convenient for consumer, and the brand recognition of product can be promoted.It simultaneously can also benefitIt is promoted in consumer in product, the brand image of erect product in the minds of consumer.
If fruit product is non-certified products, platform is traced to the source in cloud can also be by the production factors information and original production factors of decryptionInformation is sent to consumer end after being identified respectively, such as by original production factors information is with green or " certified products producesThe word markings such as information ", by the production factors information (i.e. personation production information) of decryption with red or " personation production information "Equal word markings similarly can also carry out identical processing to true and false factor of circulation information, and in there is multilevel flow to have trade relationsSituation, cloud trace to the source platform can also by the circulation information of personation and true circulation information correspondence be sent to consumer, so as toWherein intermediate links of problems are directly determined from numerous circulation quotient in consumer, it in this way can be intuitive in order to consumerThe difference between certified products and the production current intelligence of fake products is recognized on ground, increases the subsequent prevention to similar fake products and anticipatesKnow, while knowing simultaneously convenient for user counterfeit with true factor of circulation information, certain suggesting effect is being played to userUnder the premise of, user can also be warned in order to which user reports relevant departments.
In a kind of possible embodiment, consumer end receive cloud trace to the source platform feedback the true and false and circulationAfter the feedback result of situation, it can will show according to product according to the successive carry out level of currency with the circulation to productPath is visualized, such as is shown with tree form, such as is shown in the form of text according to time order and function, orPerson can mark each circulating positions on map with time order and function or different colours, to facilitate user can be to the stream of productPath, which has, to be got information about, and allows user that can more intuitively know the complete circulation path of product, and then promote consumptionEntertaining, while preliminary true and false judgement can also can be carried out to the current intelligence of product convenient for consumer.
