Description

A kind of commodity counterfeit prevention and tax-supervise system system ensemble

Technical field

The present invention is mainly concerned with field of anti-counterfeit technology, refers in particular to a kind of commodity counterfeit prevention and tax-supervise system system ensemble.

Background technology

At present, the commodity counterfeit prevention based on technology barriers mainly contains: laser anti-counterfeit, false proof, the special paper China ink of watermark is false proof, lead sealing is false proof, fluorescence falsification preventing, magnetic anti-counterfeit, temperature become false proof, specific information is false proof and special plate-making is false proof or the like.But the high evil spirit in road is high, and nearly all best brand of product is still by forgery and illegal imitation of brand-name products.This is because there are three problems in these anti-counterfeiting technologies: the one, and the easy anti-counterfeiting technology of being discerned by masses, because of textural association easily is decrypted, technology easily spreads, anti-counterfeiting mark is stereotyped easily by counterfeit, antifalse effect is often undesirable; The 2nd, be difficult for or can't be by counterfeit anti-counterfeiting technology, because of losing, the professional instrument of specific information needs that adds and specialized knowledge discriminating discern the crowd that link presets in the anti-counterfeiting mark production run, and make the antifalse effect of this technology have a greatly reduced quality; The 3rd, these are had based on anti-counterfeiting technologies of technology barriers in case by the counterfeiter or after counterfeit cost reduces, will lose anti-fake effect, become manufacturing and marketing the fake person's umbrella on the contrary.Owing to these reasons make them occupy after the false proof mainstream technology.

In the prior art, " systems engineering of national code telephone service " Chinese patent----cipher counterfeit-proof marker of being promoted by Chinese false proof employer's organization tissue (application number: 95203425.5) open the new situation of commodity counterfeit prevention.This anti-counterfeiting mark that adopts number to encode than false proof means such as laser tag, watermarks, has had essential progress, and querying method is also very easy, rapid.But there is following shortcoming in this method: 1. reclaim the phenomenon that old coding fakes, the fakement phenomena that " printing a yard " arranged more; 2. once (can not inquire about and the dealer also can't inquire about) for final user inquiry only at before sales; 3. in addition the fake producer can also forge false proof center; 4. future, contingent exhaustive attack was with a large amount of codes that cancel; 5. because false proof center is to be in charge of by special anti-sham campany, this can cause commodity production producer inquiry cost to increase, and producer's anti-counterfeiting phone data problem such as may divulge a secret; 6. used private mark (being covered) and can't finish automatic input by certain overlayer; 7. 800 freephone popularity rates not high and surpass the then anti-sham campany of certain inquiry rate with the corresponding telephone expenses of unable burden, be difficult to get through and shortcoming such as message search cost height; 8. do not combine with other equipment (as cashing machine) or software (as selling software), we think that code anti-fake is a systems engineering rather than only relies on the problem of a software with regard to solving; 9. each anti-sham campany or false proof center often separately the battle array; the neither one national standard; the dedicated query terminal that is aimed at own Antiforge system that different anti-sham campanies uses; and can not be applicable to other false proof centers; this will limit the further developing of technology of Antiforge inquiry greatly; for example the product that is subjected to a false proof center protection can not be only sold in a market; and when selling the product of other false proof center protections; then need buy different inquiry terminals, this is the thing that is difficult to accept for the market.Wherein Zui Da shortcoming was low inquiry rate.For example, because the best inquiry rate of present false proof code is approximately 10% low person less than 1%.For 6188889.3388 of a certain false proof codes this code being repeated 10 then has 80% probability can not be found, and this makes the fake producer can utilize this principle to print in a large number false proof code, and very big may still not being found arranged.

Simultaneously, as another important step----tax control link in the production marketing, current taxation control system function has bigger limitation, comprises following aspect specifically:

1., mainly be by control the cash gathering of sale enterprise in cashing machine built-in encryption module.Why the tax control machine of this characteristics can control the tax affairs of retailer well, is because these enterprises must rely on the cashing machine sell goods.But not exclusively rely on the enterprise of cashing machine sell goods for other: as manufacturing enterprise and wholesale dealer when the sell goods, may not use cashing machine, also do not draw a bill simultaneously (this according to statistics commercial activity may account for some all sales behaviors of enterprise 50%), the tax revenue of country will be subjected to very big loss this moment;

Do not need to deduct when 2., some unit buys product with VAT invoice, also do not carry out the Antiforge inquiry of invoice, if this unit has used the invoice of writing out falsely or has used false invoice, owing to the limited supervisory ability of state tax authority, then the found chance of these problem invoices of this enterprise is seldom in addition;

3., because the current VAT invoice that has produced of all using national revenue department to provide, the enterprise that receives VAT invoice on the one hand worries that invoice is stolen, and on the other hand, when a certain invoice is cancelled, when the purchaser has accepted anti-fake taxation control invoices that the supplier leaves with the VAT invoice of cancelling, may stand unnecessary loss;

4., can only control the VAT invoice part, and for other tax revenue invoice, as common invoice, country then is difficult to supervision;

5., present taxation control system can not be taken precautions against following situation: if revenue department's operator and stranger collude with, then palm off invoice and can surf the Net inquiry and become true invoice;

6., at present, the inquiry of invoice and deduct cumbersome: could inquire about after when the inquiry invoice, will manually numeral being imported one by one; And when declaring dutiable goods deduction during VAT invoice, then more trouble need be through a poor efficiency step that manually with scanner whole invoice is scanned computer into and identification.Like this inquiry mode of poor efficiency is in case when very low inquiry rate occurring, the total collapse of Antiforge system then may occur;

7., can not the unit of stopping the false invoice of utilization make account, or make the problem of false account;

8., because the tax-supervise system machine mainly relies on technology barriers, if in a single day black box wherein is cracked, then state tax revenue loss is difficult to the appraisal;

After if tax-controlling card is lost, the unit that picks up just may utilize this card to play tricks, cancel even lose unit statement, also is difficult to avoid this behavior, because present taxation control system is not surfed the Net often.If the purchaser carries out value-added tax deduction and also do not carry out under the situation of Antiforge inquiry not needing, country will lose relevant tax revenue.

10), finish the sale of current customer, and change step 2) prepare to new client's sell goods.

False proof center groundwork program circuit synoptic diagram as shown in Figure 6, two functions are mainly finished at false proof center: the one, finish false proof preliminary work (this comprises: generate product batches anti-counterfeiting information and product unit anti-counterfeiting information, generate security code, generate and put up work such as anti-counterfeit bar code); Another function is to finish anti-fake certificate work; Also have other additional functions: as the generation and the renewal work of local certificate repository.

From these three aspects false proof central task program circuit shown in Figure 6 is described below:

(1), false proof preliminary work

A), 600-5 generates batch anti-counterfeiting information and is kept in the false proof database.These information comprise: the country of production firm number, factory trading company, product sales area number, product type number, commodity sign code, product batches, retail guide price, wholesale guide price, batch key, production date, term of validity etc., wherein batch key is for generating the key of this false proof ciphertext in batch products unit, random number generator by the information security module generates, and then registration gets final product other information according to production information;

B), 600-9 generates each product unit anti-counterfeiting information and is kept in the false proof database.Product unit (referring to product consumption unit and storage unit) anti-counterfeiting information comprises: unit rank, commodity sign code, serial number, product batches number, retail sign, retail date, integrity flag, higher level's unit number, the initial serial number in subordinate unit, subordinate unit stop serial number, middle quotient, current agent, agents at different levels code etc.; Wherein, " unit rank " represents the residing rank in this unit (seeing Figure 11 and explanation thereof), " retail sign " is that this product of true respresentation is by retail, " integrity flag " can wholesale or retail for true time, " current agent " shows whom product just sold by, " higher level's unit number " shows the storage unit serial number of depositing this product unit, " the initial serial number in subordinate unit; the subordinate unit stops serial number " shows respectively then that the product unit of being deposited by this unit is initial and stops serial number that (consumer unit (as a cigarette package) is not deposited subordinate's product unit certainly, and a cigarette (storage unit) can be deposited 10 continuous cigarette packages of serial number (as from 0021 to 0030);

C), the symmetric cryptography function in the 600-12 recalls information security module is encrypted the false proof ciphertext (see Figure 10 and explanation thereof) that can obtain product unit to the identity code (seeing Figure 10 and explanation thereof) of product unit with result and this random number of the functional value XOR of certain random number with batch key.At last, can obtain security code by false proof center domain name, level code, commodity sign code, batch number and false proof ciphertext;

D), 600-14 bar code processing module encodes to security code by the coding rule of two-dimensional bar code and obtains anti-counterfeit bar code and it is printed on the antifalsification label, at last antifalsification label is sticked on the product external packaging.The antifalsification label that requirement is puted up must keep the corresponding relation between the product unit identity code in the false proof database (specifically with reference to Figure 11 and explanation thereof).

(2), anti-fake certificate work

The groundwork of anti-fake certificate is to sell authentication query.Here, we are that example illustrates with POS sale authentication query only.Mainly comprise two parts in the inquiry request message: anti-counterfeiting information and marketing information, wherein anti-counterfeiting information comprises commodity sign code, product batches and false proof ciphertext.

In general, for any information of receiving and sending, all suppose the recalls information security module sign/encrypt and decipher/verify.Below work and promptly suppose and under the errorless situation of requestor identity checking, carry out.

A), 600-6,7,10 finishes anti-counterfeiting information and tentatively authenticates.600-7 obtains key according to commodity sign code in the anti-counterfeiting information and product batches from database, and according to the false proof ciphertext in Figure 10 and the explanation deciphering anti-counterfeiting information thereof and can obtain identity code ', then, 600-10 judge the data among the 600-6 be commodity sign code, product batches with identity code ' in corresponding information whether identical, be then to change next step to continue authentication, otherwise, show that this anti-counterfeiting information forges, change issue handling e);

B), 600-11,13,15, the false proof database of 16 contrasts are finished authentication query.If it is complete (the subordinate unit that promptly this unit comprised is not separated sale) and not by retail that and the inquiry merchant's consistent (being used to control falsifying and accident treatment) and commodity of this commercial product identification sign indicating number and current agent is arranged in the false proof storehouse, show that then these commodity can be sold, otherwise change issue handling e);

C), two kinds of registration process of selling inquiry of wholesale and retail.At first be that the registration work that this commodity unit and subordinate unit (if the subordinate unit is arranged) thereof are finished: 600-17,19 finishes wholesale inquiry registration process, i.e. this purchases of registration merchant in the record at these commodity unit and subordinate unit thereof (if the subordinate unit is arranged) place in false proof storehouse, and to put it be current agent; 600-18,20 then in false proof storehouse the mid-retail of record at these commodity unit and subordinate unit thereof (if the subordinate unit is arranged) place be masked as very, promptly finish the retail registration process.Then, 600-22 puts the integrity flag of all higher level unit (if the higher level unit is arranged) of this unit for false.

D), the reason that Reports a Problem of 600-21, problem is handled;

E), send the authentication query result.600-23 sends Query Result by network communication module to inquiry end (tax is false proof if desired also will be to tax center, trusted third party's (if important inquiry));

(3), the local certificate repository of additional work-upgrade

Local certificate repository is preserved the up-to-date effective public key certificate and the relevant information of contact unit, to improve the efficient of authentication.Can upgrade certificate repository or before every day work, upgrade the up-to-date public key certificate and the relevant information of contact unit in morning every day., also can be saved after authentication effectively for the public key certificate of strange unit.

As shown in Figure 7, workflow synoptic diagram for trusted third party of the present invention, trusted third party is as the public key certificate bulletin and the certification authority at the related enterprises and institutions of this Antiforge system, the false proof center of enterprise and tax center, also be the notary organization of the important tax invoice in tax center (as VAT invoice) simultaneously, the checking of unit and false proof center public key certificate and the authentication query at daily management mission and the unit of providing and false proof center, the notarization of important invoice and certificate repository update service are provided in groundwork.Preserve the public key certificate (its form according to X.509 V3 standard) at registered juristic person unit and false proof center in the certificate repository, certificate repository is also preserved other data at registered juristic person unit and false proof center.

From four aspects trusted third party shown in Figure 7 workflow is described below.

(1), trusted third party's fill order 700-3 registration, change, cancellation unit or false proof center

1), legal entity's this Antiforge system of applying for the registration of

The legal entity that application adds this Antiforge system (comprises industrial and commercial enterprises, revenue department (tax center), anti-sham campany etc. possesses the unit of legal personality) must carry relevant data and apply for registration of to the trusted third party of locality, these data comprise its legal person's certificate (industrial and commercial operation license), tax registration certificate, manage the trade mark of product, digital certificate (is respectively applied for and encrypts and signature verification for 2 parts, can not generate for it by trusted third party if having) and other certificates that need, checking is errorless through trusted third party, then important content and the relevant information that these data comprised can be kept at the line number word signature approval of going forward side by side in the certificate repository, announce its information in the suitable time then, finish registration work.

2), registered unit is at this Antiforge system false proof center of applying for the registration of

Have only after trusted third party applies for the registration of, false proof central party can obtain the false proof qualification of approval in native system.False proof center can not add this Antiforge system with status of a legal person (being that false proof center does not possess legal personality); can only add as the affiliated institutions of unit or anti-sham campany; therefore; only after native system was finished registration, product was protected at the false proof center of could apply for the registration of false proof center or the anti-sham campany of trust in legal entity.The registrable a plurality of false proof centers of certain legal entity; but the false proof center of manufacturing enterprise can only protect our unit's registered trademark (in native system; the protection registered trademark is meant that the product to using this registered trademark carries out anti-fake certificate), and the false proof center of anti-sham campany is in the registered trademark that can protect agent authorized after entrusting the unit mandate.

False proof center must be provided the data of protected registered trademark, false proof center domain name, 2 parts of false proof center digital certificates, be reached other data when applying for the registration of.Errorless through trusted third party checking, in certificate repository, preserve this application for information about and through the digital signature approval, announce its information in the suitable time then, finish this false proof center registration work.

3), change, cancellation unit or false proof center

When registered legal entity or false proof center need be changed, during operation such as cancellation, can carry out as long as supply relevant data.

When the false proof center of anti-sham campany increases protected trade mark, the contract of authorization, registered trademark data, and other data that need of clientage (clientage must in the native system registration) signature must be provided, but clientage's registered trademark can only be protected.

When the false proof center of manufacturing enterprise increases new protected registered trademark, as long as provide the data of this registered trademark.

Errorless through trusted third party checking, preserve this and operate in the certificate repository and and carry out the digital signature approval update, announce its information in the suitable time then, finish this work.

Above data generally formally effective at second day (this is because each registered units generally only carries out the certificate repository down loading updating in every day before the work) is if urgent the renewal then receives urgent the renewal by each registered units of responsible proactive notification as soon as possible of trusted third party.

(2), 700-4 certificate repository update service

According to the update request of update request end, trusted third party after compression and digital signature, sends to the requesting party with nearest renewal or the needed unit of requesting party and false proof central information (comprising public key certificate and relevant information).

Can be any lastest imformation that tax center is not provided in the unit of this center registration.

(3), the authentication query processing of request at 700-5,8,11 pairs of units or false proof center

For the authentication query of legal entity, trusted third party need check following condition: whether certified legal entity is in validity of the public key certificate of native system registration, the character of unit, the registered trademark that has, this unit etc.

For the authentication query at false proof center, trusted third party need check following condition: the authority of this registered trademark of this enterprise of protection, the validity of its public key certificate etc. are registered, whether had in certified false proof center whether.

If above condition is all out of question, then returns essential information and the public key certificate and the legal sign at certified legal entity or false proof center, otherwise return the details and the illegal sign of problem to the request end.

(4), 700-6,7,9, the 13 pairs of important invoice notarization in tax center processing of request processes

1. number be foundation with same legal entity the same request of making out an invoice, the anti-fake certificate result who sends according to each false proof center examines the tax data in the invoice notarization request; If 2. audit meets the requirements, then the call format according to tax center carries out issuing tax center after the digital signature to data; 3. otherwise change issue handling;

As shown in Figure 8, workflow synoptic diagram for tax center among the present invention, tax center is the affiliated institutions of the tax bureaus at various levels, can be divided into according to China revenue department hierarchical structure: national general bureau tax center, province office tax center, districts and cities office tax center, county telephone central office tax center.The taxes at different levels center at first obtains public and private key and digital certificate by certain way, and after digital certificate is announced separately in mechanism of trusted third party registration, can normally carry out the work, this comprises: taxpayer's qualification authentication, the service of drawing a bill in real time is provided, tax tax control work such as invoice authentication query service are provided.

Tax central task flow process shown in Figure 8 is described from three aspects below:

(1), 800-3 finishes taxpayer's qualification authentication

To the legal person who possesses the qualification of paying taxes register, change of registration, cancellation registration and other registrations.As long as legal person's certificate (industrial and commercial operation license), pertinent certificate and digital certificate are provided, through examining requirement up to specification, can grant registration, relevant information is kept at the tax information database.

(2), 800-4 etc. finishes the service of drawing a bill

Suppose that the information security module has been verified the legitimacy of sender's identity and the validity of data when receiving request of drawing a bill or commodity counterfeit prevention authentication message.

1. 800-4 receives request of drawing a bill and related data; 2. the sales data in the true and false and data audit: the 800-10 request of will making out an invoice compares with the authentication message of sending from relevant false proof center, if be verified as true and consumption sum no problem by sell goods, then continues next step, otherwise changes issue handling; 3. generate common or important invoice: if request generates common invoice, after then the amount of tax to be paid is answered in calculating according to the tax rate by 800-15, generate the common invoice data and be kept in the tax information storehouse, change 800-27 simultaneously.If request generates important invoice (as VAT invoice), then calculate tax liability according to the commodity tax rate and generate the invoice tax data by 800-16,800-20 issues trusted third party's notarization with the tax data of invoice then, receiving that third party's data that 800-24 and 800-16 as a result generate of will notarizing of 800-21 after the message of notarizing compare, if no problem then be attached to and change next step after generating important invoice data behind the invoice tax data and being kept at the tax information storehouse, otherwise change issue handling by the 800-25 signature of will notarizing; 4. 800-27 tax center is carried out digital signature to invoice data and is obtained electronic invoice (also may need sometimes data such as invoice, digital signature are carried out barcode encoding); 5. 800-29 sends to the requesting party that makes out an invoice with electronic invoice.

(3), 800-5 etc. finishes the service of various invoice authentication query

1. 800-5 receipt of invoice authentication query request; 2. digital signature validity and data consistency authentication: 800-8 at first verifies the digital signature of invoice, inquire about then in the invoice data preserved in the tax information storehouse and the request invoice data whether once, if signature effectively and data consistent then continue next step, otherwise change issue handling; 3. various authentication query is handled (for the sake of simplicity, we temporarily only consider three kinds of authentication challenges): the common authentication query of A. (only inquiring about the true and false and the invoice reimbursement deduction situation of invoice), 800-19 changes next step read reimbursement deduction information from the tax information database after; B. submit an expense account authentication query (being the query requests that certain treasurer's department of unit sends to tax center the invoice of being rendered an account), 800-18 checks that the requesting party has no problem and this invoice whether to be submitted an expense account, if two aspects are no problem all, then 800-23 writes down this inquiry unit in the reimbursement field in this invoice (in the tax information storehouse), continues next step then; C. authentication query: the 800-17,22 that deducts checks that requesting parties have no problem, this invoice whether to be submitted an expense account and deducted and whether other aspects have problem (for example: deduction inquiry unit and purchasing unit are to denying whether purposes consistent, goods satisfies deduction condition etc.), if tax deduction is carried out for the inquiry unit in these aspects all no problem then 800-26, and 800-28 this inquiry unit of registration in the reimbursement field of this invoice (in the tax information storehouse) and deduction unit field; 4. 800-31 sends Query Result to the inquiry end, and this authentication query service finishes.

As shown in Figure 9, workflow synoptic diagram for tax inquiry end among the present invention, the 900-1 groundwork comprises: system initialization, operator import the user name and password and upgrade local certificate repository, the renewal of the taxes especially at different levels center digital certificate to confirm identity and recalls information security module.

The process of an invoice of tax inquiry end inquiry is as follows:

1. the bar code on invoice of 900-2 scanning can obtain corresponding electronic invoice (comprising information such as invoice code, invoice number, the date of making out an invoice, the side's of purchasing number of paying taxes, the number of paying taxes of pin side, commodity sign code, the amount of money, the amount of tax to be paid and digital signature); 2. whether the digital signature on the 900-3 recalls information security module checking invoice is effective, invalidly then changes issue handling, otherwise continues next step; 3. dissimilar query processings: the common authentication challenge of A. invoice: 900-5 sends information such as " query type, invoice data, invoice signatures " to tax center; After receiving the authentication result of returning at tax center, 900-8 (validity that needs recalls information security module authentication verification result) judges according to authentication result content (comprising situations such as the true and false, reimbursement and deduction): if false invoice or submitted an expense account/deducted and then changeed issue handling, otherwise 900-11,13 preserve (electronics) original certificates and fill and present accounting voucher (this invoice must by reimbursement or deduction authentication query could as effective original certificate examined by and record keeping); B. the processing procedure of reimbursement inquiry and deduction inquiry: 900-6 or 7 sends information such as " query type, invoice data, invoice signatures " to tax center; After receiving the authentication result of returning the Help Center, 900-9 (validity that needs recalls information security module authentication verification result) judges according to authentication result content (comprising situations such as the true and false, reimbursement and deduction), if false invoice or submitted an expense account/deducted and then changeed issue handling, otherwise 900-12,14,15 add the authentication signature at tax centers and preserve (electronics) original certificate or on the electronics original certificate of having preserved, add tax center authentication signature, fill and present/revise accounting voucher and examine accounting voucher.

As shown in figure 10, be the structural representation of anti-counterfeit bar code among the present invention, the anti-counterfeit bar code content comprises three parts: false proof center domain name 1000-1 (must with false proof center being consistent in trusted third party registration), commodity rank batch sign indicating number 1000-2, false proof ciphertext 1000-3.Wherein: 1. commodity rank batch sign indicating number 1000-2 is made up of level code 1000-5 (level of representative products unit sees the explanation of Figure 11 for details), commodity sign code 1000-6 (with reference to GB12904-2003), batch number 1000-7; 2. 1000-8 is the generative process of false proof ciphertext 1000-3: false proof ciphertext=E Key(identity code Integer 1, integer 2), to be symmetric cryptography function E with batch key (can with increasing key safety than complicated approach) encrypt the result of identity code 1000-4 (abbreviation identity code) Yu integer 1 XOR of product unit (promptly expressly part 1) and integer 2 (i.e. plaintext part 2) obtains false proof ciphertext, wherein, identity code 1000-4 is by level code 1000-5, commodity sign code 1000-6, batch number 1000-7 and serial number 1000-9 form, integer 1=L (integer 2) is that certain stuffing function L acts on integer 2 (being a random number) and the number isometric with identity code that obtain It is xor operation.

On the contrary, can from false proof ciphertext 1000-3, obtain product unit identity code 1000-4 according to the following procedure:

1. false proof plaintext=decryption function Key(false proof ciphertext), decryption function is identical with encryption function E, and key is an encryption key; 2. part 1 in product unit identity code=false proof plaintext L (part 2 expressly).

As shown in figure 11, among the present invention product unit deposit the hierarchical relationship synoptic diagram, false proof center product unit promptly leaves in the high rank unit with a kind of product low level product unit according to the order of depositing from rudimentary to senior.Use " D-C-B-*? " among the figure or the identity code PID of " D-C-B-* " expression product unit, the implication of forming is: the rank of digital D representative products unit is D, C represents the commodity sign code, B representative products batch number, * represent the some bit digital in front or the whole serial number of serial number,? represent a tens digit.Here product unit refers to the storage unit of consumer unit and different stage.

Be exemplified below:

A kind of cigarette, commodity sign code be 1234567890123,071101 batches 10000 cigarette packages (genus consumer unit) and storage unit to deposit relationship description as follows:

1. the identity code PID that establishes this ten thousand cigarette package (belonging to 0 grade of unit) is: 0-1234567890123-071101-00001,0-1234567890123-071101-00002, ..., 0-1234567890123-071101-10000, wherein '-' can remove for separator; 2. this ten thousand cigarette package is assembled into 1000 cigarettes (belonging to 1 grade of unit), and their identity code PID are: 1-1234567890123-071101-0001, and 1-1234567890123-071101-0002 ..., 1-1234567890123-071101-1000; 3. then these thousand group, of cigarettes are dressed up 20 casees cigarettes (belonging to 2 grades of unit), identity code PID is: 2-1234567890123-071101-001, and 2-1234567890123-071101-002 ..., 2-1234567890123-071101-020; 4. corresponding relation: suppose that this 10 cigarette package of 0-1234567890123-071101-00001~0-1234567890123-071101-00010 leaves in this cigarette of 1-1234567890123-071101-0001, same these 50 cigarettes of hypothesis 1-1234567890123-071101-0001~1-1234567890123-071101-0050 are left in again in the 2-1234567890123-071101-001 case, and the relation of depositing of this product unit must correspondingly be reflected in the false proof database.

This corresponding relation can significantly improve the efficient of Antiforge inquiry.If look into the true and false of a FCL cigarette,, and do not need each bag in this case or each bar cigarette are carried out Antiforge inquiry then as long as inquire about the security code of this case.

As shown in figure 12, workflow synoptic diagram for information security module among the present invention, the information security module is mainly finished three functions: to the message that sends is carried out digital signature and encryption, the message that receives is decrypted and verifies the signature of transmit leg, upgrade local certificate repository, wherein preceding two functions show at needs and use when confirming correspondent's identity, the purpose of design of local certificate repository is to improve verification efficiency in order to reduce Internet traffic, a part that belongs to trusted third party's distributed certificate storehouse content is upgraded local certificate repository and is in order to guarantee local certificate repository consistent with the trusted third party certificate repository.
