[specific embodiment]
Below in conjunction with accompanying drawing the present invention is described in further details, described professional equipment manufacturing technology and foods processing technique also are very clearly concerning these professional personnel.
Shown in accompanying drawing, there are five steps in system of the present invention:
1.Tag the manufacturer produces Tag and writes anti-counterfeiting mark, sells then and gives product producer.
2. product producer is implanted to Tag in the product at the streamline of oneself, sells then and gives dealer's (comprising wholesale dealer and retailer).
3.Reader the manufacturer produces false proof Reader, sells and gives the dealer, is used to differentiate the true and false of the product of product producer.
4. the dealer sells product (comprising the Tag that plants on product) and gives the ultimate consumer.
5.Reader the manufacturer Reader by Reader dealer or directly sell and give the consumer.The consumer can differentiate the true and false of the product that is implanted with RFID Tag with this Reader.
False proof flow process is as follows:
1. this step is finished when producing Tag.Anti-counterfeit server generates anti-counterfeiting mark for each Tag, writes in the designated user district of Tag, and produces a unique Tag record at database.
2. this step is finished when producing Reader.Anti-counterfeit server generates unique anti-counterfeiting mark for each Reader, writes in the inside designated storage area of Reader, and produces a unique Reader record at database.
3.Reader read the anti-counterfeiting mark of Tag.
4.Reader import the anti-counterfeiting mark of Tag into PC by USB.
5.PC the Driver program import the Tag anti-counterfeiting mark into anti-counterfeit server.Anti-counterfeit server is discerned the false from the genuine by analyzing anti-counterfeiting mark.
Above step is basic false proof flow process.Actual data transmission details can be narrated in anti-fraud system, mainly also comprises:
1.Reader before reading the anti-counterfeiting mark of Tag, also need to verify oneself by PC and anti-counterfeit server.
2. anti-counterfeit server be must be with the inside anti-counterfeiting mark renewal of Reader after very at checking Reader.
Anti-counterfeit server covers the anti-counterfeiting mark of Tag by Reader for the anti-counterfeiting mark after must returning renewal after very at checking Tag.
The detailed process of Antiforge system mainly comprises two parts:
1. generate the anti-counterfeiting mark of label and read write line, mainly on the production line of label and read write line, realize;
2. the communication process between read write line, label, PC and the anti-counterfeit server.
Native system is mainly considered the complicacy that reduction system as far as possible installs on communication construction, avoid too much system combination, makes the installation of system and debugging easier, more efficient, and the cycle shortens.
From above-mentioned communication construction, have only the production line of label and read write line and dealer and terminal user need be connected to anti-counterfeit server, and need false proof product producer to need not to be connected with anti-counterfeit server.Label and read write line factory entrust relative fixed in principle; Dealer and terminal user only need directly to be connected to anti-counterfeit server by Internet by PC, do not need extra integration, and the driving that only needs read write line is installed at PC gets final product.Like this, the communication construction of total system is just very simple: anti-fake product manufacturer of every increase, need not to carry out the system combination of manufacturer aspect, and only need to locate to dispose read write line and get final product with installing to drive its dealer.
Needing to install special-purpose read-write equipment on the production line of label and read write line to write anti-counterfeiting mark to the internal memory of label and read write line.Anti-counterfeiting mark is obtained to the center anti-counterfeit server by special-purpose read-write equipment.Can directly visit anti-counterfeit server on its specific implementation, also can be by pc access.It below is the flow process of obtaining anti-counterfeiting mark.
Online anti-fraud system mainly comprises two partly:
1. implant one section enciphered data (Tag anti-counterfeiting mark) in user data area (User Bank) lining of EPC standard Tag, connect PC and anti-counterfeit server by Reader then and exchange this segment data and realize real and fake discrimination.This section enciphered data can dynamically update when each and false proof service area is mutual.
2. one section anti-counterfeiting mark of Reader storage inside that uses the terminal user.Reader verifies self by PC and mutual this section anti-counterfeiting mark of anti-counterfeit server earlier when discerning Tag.In case passed through the checking of anti-counterfeit server, just can carry out identification to Tag.
Anti-fraud system is mainly faced three parts: Tag, Reader, and the Driver of Reader on PC.When these three parts all are forged, then can't handle naturally.As long as there are parts not to be forged, Antiforge system just has the ability to discern the false from the genuine.
Duplicate if Tag is stolen, anti-counterfeiting mark also is replicated so.Following two kinds of situations are arranged:
1. true Tag has at first carried out false proof discriminating by Reader, and then its anti-counterfeiting mark will be updated, and server end also can corresponding more new database.Certain pseudo-Tag also attempts to carry out anti-counterfeit recognition by Reader then, but because the serviced already device of its anti-counterfeiting mark upgraded, invalid, and the anti-counterfeiting mark generating algorithm can guarantee not repeat to generate used value, is to forge so Reader can identify.
2. pseudo-tag at first carries out anti-counterfeit recognition by Reader, and then its anti-counterfeiting mark will be updated, and the database of server end also is updated.The true Tag of the product of certain user's purchase also attempts to carry out anti-counterfeit recognition by Reader then, owing to anti-counterfeiting mark is updated, so can be judged to forgery.At this moment, the user can contact directly the true and false by the artificial cognition commodity with the product producer customer service, if be true really, then product producer must and the brightness contact, this Tag is deleted from server end, remain valid in order to avoid forge Tag.
Because each Tag has only a unique ID, even if adopt the method for duplicating to forge, also can only forge one, can't forge large batch of Tag.And the randomness of Tag anti-counterfeiting mark generating algorithm and immeasurability can prevent that the adulterator from guessing the Tag anti-counterfeiting mark.
Product producer has a responsibility for avoiding Tag to be repeated to use.Manage to accomplish to be difficult to dismounting when being installed to Tag on the commodity such as product producer, in case pull down, Tag just is damaged.But if the manufacturer does not have very good way to accomplish this point, the existing mechanism of then false proof algorithm prevents from or reduces Tag to be repeated to use.Scheme is as follows:
1. limit the valid period of Tag ID
Each unique Tag ID can only be in the time limit that limits effectively.In case surmount this time limit, it is invalid then to be considered as.Such as valid period with the valid period definition of T ag ID of commodity itself.Consumed before valid period in case shortcoming is commodity, then this Tag ID might be diverted to other purpose.
2. limit the access times of Tag ID
Such as limiting 100 times.It is invalid then to be considered as above number of times.
3.Tag set producer or model in the record
In false proof database, the name of definition corresponding commodity producer maybe may be used for marque during every Tag write down.In false proof label managing web, the information that provides interface to set each batch label buyer comprises the product producer name, with TID (because TID has defined the exclusive information of product producer) of using or the like.The data that anti-counterfeit server will adopt the TID information that reads from Tag to search for factory return to PC and are shown on the screen.Advantage is to limit the attempt that Tag is used for different product.
We combine use with three schemes, set a multiselect item in the Tag record, define which qualification scheme of use.
The purpose of forging Reader mainly is for pseudo-Tag is judged to very.So in case there is pseudo-Reader to flood market, then the front provided, and to prevent that Tag is replicated with reusable method just invalid.Solution is as follows:
1.Reader middle configuration certain chip prevents the Engineer by Reverse.
This mechanism prevents that the internal logic of Reader is replicated, and prevents that also the anti-counterfeiting mark of Reader is stolen.
Be used for self-authentication 2.Reader set unique anti-counterfeiting mark.
Reader must carry out self-authentication by server earlier before Tag is carried out false proof evaluation.Here the Driver that supposes PC remains genuine.
The PC interface should show that product producer etc. and product are for information about.
Owing to preserve manufacturer's information of Tag ID correspondence in the record of Tag, if the PC interface can prevent then that showing product related information by false proof evaluation back Tag is repeated to use in the different product.And,, and obtain Tag information smoothly if use genuine PC Driver for counterfeit Reader, then this information also is the information of the original used product of Tag; If the PCDriver with forging then can't show the Tag product information, because these information are stored in server; Also might forge the merchant and construct a series of Antiforge system and serve fake product, the cost of then doing so almost be exactly and genuine Antiforge system similar, be difficult for realization.
The Driver of Reader on PC attacked or the purpose of counterfeit this attack is in order to cooperate counterfeit Reader by reading the checking of pseudo-Tag.Two kinds of situations are arranged:
1.Reader be true, Tag is by counterfeit or repeated use.
If the Driver of non-brightness exploitation and genuine Driver are identical, then meaningless, do not consider (Driver itself is free, as long as function meets the standard of brightness, no matter who exploitation all is fine).Because Reader be true, Reader can be mutual according to agreement and Driver that anti-fraud system defines, and Driver should be shown on the interface with the merchandise news that Tag is obtained in the server communication.Because Driver is false, not and the brightness server get in touch, just do not have the information of possibility demonstration Tag yet.
2.Tag be true, Reader is counterfeit.
This situation needn't be considered in fact, because Reader is false proof main object of action, even if Tag is true, does not also have the meaning of differentiating.
The setting of the length of anti-counterfeiting mark can be with reference to following 3 points:
1. security.Long more in theory, it is high more to crack difficulty, also just safe more.
2. uniqueness.Because each and anti-counterfeit server all can be upgraded the anti-counterfeiting mark in the Tag alternately.Optimal situation is that each new anti-counterfeiting mark that produces is unique, never two identical anti-counterfeiting marks generations.Obviously, the longer the better for anti-counterfeiting mark.Certainly, most situation is that different time can may produce identical anti-counterfeiting mark, should avoid too many repetition so produce the algorithm (in fact being exactly a kind of random number generation method) of anti-counterfeiting mark.Technically can consider that Query Database avoids the generation of identical anti-counterfeiting mark.
3. do not take the too many position of User Bank of Tag.User Bank might be used (such as non-brightness EPC Reader) by other and use), if take too many place, can limit the function of other application.From this angle, short more good more.
Brilliant accurate NXP Tag G2XM User Memory is decided to be 512bits at present, so can use 64-128bits.If adopt 128bits, and anti-counterfeiting mark plants in User Bank bottom, and the specification of Tag should illustrate that 0-383bits can use, and 384-511bits is unavailable district.
The Tag anti-counterfeiting mark is write the bottom of User Bank, and doing like this is to use the User Bank that uses Tag in order not influence other.The start address computing method of anti-counterfeiting mark are as follows:
Anti-counterfeiting mark start address=User Bank bit number-anti-counterfeiting mark length
How to obtain the size of User Bank? because the structure of the TID of the Tag of different size has unique rule, below is the description of EPCglobal to TID:
TID?memory?shall?contain?an?8-bit?ISO/IEC?15963?allocation?classidentifier(111000102?for?EPCglobal)at?memory?locations?00h?to07h.TID?memory?shall?contain?sufficient?identifying?informationabove?07h?for?an?Interrogator?to?uniquely?identify?the?customcommands?and/or?optional?features?that?a?Tag?supports.For?Tagswhose?ISO/IEC?15963?allocation?class?identifier?is?111000102，this?identifying?information?shall?comprise?a?12-bit?Tag?mask-designer?identifier(free?to?members?of?EPCglobal)at?memorylocations?08h?to?13h?and?a?12-bit?Tag?model?number?at?memorylocations?14h?to?1Fh.Tags?may?contain?Tag-and?vendorspecificdata(for?example，a?Tag?serial?number)in?TID?memory?above?1Fh.
So, can obtain the specification of Tag by the value that reads TID layered front portion bit, and then know the length of User Bank.Technical, can set up the TID sign of the Tag that all brightnesses of a form stores produce at server end.According to the sign that Reader obtains from Tag, server can be told this Tag of Reader the whether size of the false proof Tag of brightness and User Bank.Reader just can do respective handling like this: perhaps be considered as non-false proof Tag, perhaps calculate the position of anti-counterfeiting mark and read the Tag anti-counterfeiting mark.
The generation of anti-counterfeiting mark has two kinds of situations:
1. the one of the main divisions of the male role in traditional opera produces initial anti-counterfeiting mark when producing Tag.
2.Reader during checking Tag, anti-counterfeit server produces new dynamic anti-fake sign.
Anti-counterfeiting mark comprises three kinds of information:
1. unique constant ID of each Tag, i.e. Tag ID.The quantity of Tag can be very huge, and Tag ID must be unique, and then Tag ID answers long enough.
2. dynamic random sign indicating number.The dynamic random sign indicating number is used for dynamically changing the false proof data of Tag, should long enough to guarantee in very long one time, not having repetition.
3. identifying code.The identifying code that anti-counterfeiting mark also needs to comprise a location number is used for the validity of the false proof data of preliminary identification.
Consider the size restriction of the Memory of Tag own, if with the length of 128bits as false proof data, suggestion Tag ID is shorter slightly than dynamic random sign indicating number:
Tag ID length
Tag?ID：56bits＝2
56≈7×10
16
Should be enough.But algorithm must have the ability to be extended to longer length.
Dynamic random code length: 64bits=2
64≈ 1.8 * 10
19
If per second has 1000 visits and changes, then in theory 5.8 * 10
8Can produce unique random code in year.Certainly, because the limitation of algorithm design does not reach this theoretical value, but also enough.
Identifying code: 8bits
Identifying code is that (result of hash is got in mixing, places last usually to the combination of Tag ID and the dynamic random sign indicating number of the 120bits of front.
Tag ID can generate in proper order.Tag of every manufacturing just produces the sequence number of a 56bits as Tag ID in order.Simultaneously, set up a filtrator and avoid usurping special number.The generation of dynamic random sign indicating number
The dynamic random sign indicating number generates with randomizer, and step is as follows:
1. produce initial code with randomizer;
2. search database Tag form confirms that this generation sign indicating number is unique;
3. if there has been this numeral in database, illustrated that Tag is using this numeral, then must get back to for the 1st step and continue to produce random code.
Coding TagID becomes the many covers of anti-counterfeiting mark (Anti-C Mixing) design array modes this two numerals of encoding with the dynamic random sign indicating number, finally constitute false proof data.The mode of coding and parameter deposit in the database so that Ke Yi Xie Code during the next time visit.
The algorithm of coding is with reversible cryptographic algorithm; Also available simple combination algorithm.Each time during Reader visit anti-counterfeit server, a kind of combined method of server program picked at random and the parameter new anti-counterfeiting mark of encoding returns to Reader then.As previously mentioned, the hash that mixed 120bits coding is fixed is calculated and is stored at last.If with array byte[16] represent whole coding, then byte[0..14] be hybrid code, byte[15] be identifying code.
In case behind TagID and the dynamic random code combination coding, also need once to encode.Current coding should keep length constant and reversible, and coding result will be final anti-counterfeiting mark (Anti-C ID).Introducing this step is in order to prevent that DoS (Denial-of-Service) from attacking.General DoS attack can be dealt with by IP is filtered, and promptly same IP sends frequent requests can be stopped at the Web Server of fire wall or head end router or front end (such as Apache HTTPD).The DoS attack of more complicated may be not limited to an IP, need stop from the level of application program: the proof of algorithm that promptly the Anti-C ID that imports into is not needed database search, if can't pass through proof of algorithm, then explanation is invalid Anti-C ID, directly returns authentication failed.Otherwise, directly carrying out database search if skip this step, can pose a big pressure to database, system performance can sharply descend.
In order to reach this purpose, need a design reversible encryption algorithm (paragraph as follows), when generating Anti-C ID, encoded, after the request of receiving, can adopt reduction to calculate to see whether can effectively reduce like this.If can't effectively reduce, explanation is the Anti-C ID that forges, and should return failure, otherwise continues.
Encryption algorithm adopts the aes algorithm of fixed key, the perhaps aes algorithm of limited dynamic key.The shortcoming of fixed key is to be broken easily.Another method is the aes algorithm of the dynamic key in the certain limit, promptly preestablishes some keys, then to each key trial and error decoding, after the decoding, preceding 120bits is done hash, compares with last 8bits then, if coupling shows it is efficient coding.
A kind of situation in the false proof analysis is that Tag is stolen and duplicates use (certainly according to present mechanism, each Tag can only be once stolen), and the user who has real Tag may seek help from brightness and repair this Tag.Owing to revised the false proof data of Tag in the database, and coded system also has change, directly can't obtain this Tag information from existing database.In order to keep the information of the each change of the false proof data of Tag, should be saved in the History form each variation, so just can have an opportunity to search out old Tag and encode.
This History form is certain to big doubly more a lot than original Tag form, depends on the average time that Tag is scanned by Reader.For fear of the too huge performance that influences of database, should often file disk to this form.
Managing web must be set up user interface and manage Tag, comprises the classification of Tag, inquiry, state.
The Reader anti-counterfeiting mark is stored among the Memory of Reader.Must be at the streamline of producing Reader to the initial sign of anti-counterfeit server acquisition request.
The principle of Reader anti-counterfeiting mark and Tag's is similar, handles with identical mechanism.Its length can be set identical with Tag for, and its composition is also similar: comprise Reader ID and dynamic random sign indicating number two partly.
Below adopt the mode identical to define the anti-counterfeiting mark of Reader with Tag:
The definition of Reader anti-counterfeiting mark
1. length: 128bits
2.Reader?ID：56bits
3. dynamic random sign indicating number: 64bits
4. identifying code: 8bits
Similar with the Tag anti-counterfeiting mark, the anti-counterfeiting mark of Reader also needs periodically to file for use in the query history record.
Because the anti-counterfeiting mark of Reader and Tag with the cryptographic algorithm coding, so the communication between Reader and the PC Driver need not to use encrypted tunnel, does not just need to realize the cryptographic handshake agreement yet.Reader can directly add anti-counterfeiting mark and send PC Driver to, and the latter transfers to anti-counterfeit server and realizes decoding and discriminating.
