Description
Technical field
The present invention relates to a kind of product identification mark, Antiforge system and method, introduce more precisely intermediateness, database identification handheld device is read and write before electronic tag success beyond the clouds, in database, preserve beyond the clouds new and old product identification dynamic code and new and old authentication random code, four yards of intermediatenesses that coexist, overcome the communication disruption causing due to accidentalia in Product Validation process, the high in the clouds database causing and the inconsistent risk of electronic tag data, and by the monitoring to this intermediateness, process, the illegal operations such as label forgery clone are effectively prevented.
Background technology
Recently,, along with the continuous progress of science and technology, the NFC function of handheld device is also applied to false proof field gradually.Wherein, in the application process of Chinese invention patent CN103530785, find, due to the problem of communication disruption, have the inconsistent risk of electronic tag data of high in the clouds data and product.For example, in proof procedure, handheld device has completed label data read-write, but because electric weight deficiency causes handheld device power-off or people for closing the accidentalia such as network, cause handheld device now to stop verifying operation, communication disruption, the data of read-write cannot be uploaded to high in the clouds database, make the data in high in the clouds data and electronic tag inconsistent, cause this product in the upper serious consequence that is once verified as fakement.Although analogue occurrence probability is very little, because becoming ten thousand more than one hundred million ranks and genuine piece, product radix becomes the baneful influence of fakement, and this problem has still seriously hindered the popularization of NFC anti-counterfeiting technology.
Summary of the invention
For overcoming above-mentioned defect, technical matters to be solved by this invention is for existing patent (Chinese invention patent CN103530785), taking handheld device if mobile phone etc. is as carrier, utilize NFC and the network function of handheld device, in proof procedure, database is introduced intermediateness beyond the clouds, reaches improvement identification, realizes the false proof object that can not clone.
In order to realize foregoing invention object, the technology path that the present invention takes is as described below.
Antiforge system of the present invention comprises: electronic tag, handheld device with NFC function are as mobile phone etc., and the application software with random code systematic function and high in the clouds database four parts that are placed in high in the clouds database form.The difference of system of the present invention and Chinese invention patent CN103530785 is that random code production software is placed in high in the clouds database, and handheld device is only responsible for electronic label read-write and the communication interaction operation with high in the clouds database.
Above-mentioned electronic tag and Chinese invention patent CN103530785 are similar, comprise 3 partial datas: product identification coding fixed code, product identification coding dynamic code, Product Validation random cipher.Product identification coding fixed code can be a succession of sequence code of dispatching from the factory, and the identity coding fixed code of each product is unique, can be in some specific digits, carry out as required one or more logic codings, can comprise province, city, region sequence, circulation commission merchant sequence, type of merchandize code etc.; Product identification coding dynamic code refreshes at every turn after being proved to be successful, and complete product information is made up of fixed code and dynamic code, indispensable.
Without using auxiliary read-write authentication module, CN103530785 is similar with Chinese invention patent.Because the electronic tag carrier adopting is NFC commercial chip, as the MIFARE family chip of Dutch NXP company, F family chip of Shanghai Fei Ju Microtronic A/S etc., this class chip has a cryptographic function, when the NFC chip door password of door password and the electronic tag only obtaining from high in the clouds database is consistent, electronic tag just allows to be correlated with and reads and writes operation.
For the product of the state that do not mediate (steps A is shown in description), verification method comprises the following steps:
A. handheld device is by the product identification coding fixed code in NFC function reading electronic labels and product identification coding dynamic code, be sent to high in the clouds database, the checking of comparing, this is the first heavy false proof operation: as passed through checking, high in the clouds data base querying goes out the door password that this product is corresponding, simultaneously, utilize the random code in the database of high in the clouds to produce software, generate new product identification coding dynamic code and new Product Validation random cipher, and retain former product identification old in the database of high in the clouds coding dynamic code and the old Product Validation random cipher of being stored in, new and old two cover passwords are not identical, these four yards of states that coexist are intermediateness, subsequently, high in the clouds database is sent to handheld device end by internet by door password, new product identity coding dynamic code and new product checking random cipher, if not by checking, fakement the result is sent to handheld device end,
B. the door password that handheld device is utilized NFC function and obtained from high in the clouds database, the Product Validation random cipher in reading electronic labels, and in electronic tag, write the new product checking random cipher and the new product identity coding dynamic code that obtain from high in the clouds database;
C. handheld device is after electronic tag writes successfully, the Product Validation random cipher reading is uploaded to high in the clouds database by internet, high in the clouds database compares, verifies the Product Validation random cipher reading and old Product Validation random cipher, and this is the second heavy fake certification.As by checking, only retain beyond the clouds new product identification coding dynamic code and new Product Validation random cipher, cancel the intermediateness in the database of high in the clouds, and genuine piece the result and product related information are sent to handheld device end; If not by checking, in database, only retain old product identification coding dynamic code and old Product Validation random cipher beyond the clouds, cancel the intermediateness in high in the clouds, and send fakement the result to handheld device end.
CN103530785 is different from Chinese invention patent, and the product identification coding dynamic code, the Product Validation random cipher that in fake certification process, produce all produce in database beyond the clouds, are convenient to data storage, management and analyze.
Do not pass through the product of the second heavy fake certification for while verifying first to pass through the first heavy false proof operation; because the product identification coding dynamic code of electronic tag changes in the time verifying first; when each checking later; cannot be again by the first heavy fake certification; therefore shutter password and product related information effectively, CN103530785 is similar with Chinese invention patent.
For occurrent communication disruption, due to the existence of this patent high in the clouds intermediateness, be new product identification coding dynamic code and new Product Validation random cipher, old product identification coding dynamic code and old Product Validation random cipher, new and old two cover passwords are also deposited, this product is before checking next time, and high in the clouds database cannot confirm whether label is read and write successfully, and state therefore mediates.
For the product in high in the clouds database intermediateness, in electronic tag, identity data only need meet any a set of genuine piece that is judged to be in new and old two cover passwords, whole proof procedure and above-mentioned A, B, C step are similar, difference is only after being verified as genuine piece for the second time, just to upgrade associated cryptographic, cancel intermediateness, as be verified as fakement and continue to retain intermediateness.Compared with Chinese invention patent CN103530785, the method has solved the high in the clouds data and the inconsistent problem of electronic tag data that cause due to the communication disruption accidentally occurring effectively, has avoided product genuine piece in upper once checking to become the situation of fakement.
Database identification handheld device completes before electronic label read-write operation beyond the clouds, due to the introducing of intermediateness, there is the transitional period of the corresponding two cover identification ciphers of commodity, but it is still the corresponding a set of identification ciphers of commodity that product completes the end-state of checking, has effectively stopped the illegal operations such as a large amount of clones; Simultaneously because whole data are stored in high in the clouds database; in addition in identity fixed code, there is one or more logic codings; can pass through the monitoring to database; effectively protect the legitimate rights and interests of product: once in database at one time section or same handheld device produce a large amount of intermediatenesses; manufacturer starts relevant product exception management measure, as the related personnel of this local product supervises operation etc. in real time.
Practical function of the present invention is: first only need in the situation that network is unobstructed, can realize false proof operation with the handheld device of NFC function, checking necessary condition is simple, and CN103530785 is similar with Chinese invention patent; Secondly, due to the existence of intermediateness, compared with Chinese invention patent CN103530785, effectively overcome the communication disruption occurring due to accidentally, make high in the clouds data and electronic tag data inconsistent, cause this product once to verify that upper genuine piece becomes the problem of fakement; Again, by the monitoring to intermediateness, effectively prevent from forging the illegal operations such as clone's label, reach real false proof object.
