Background technology
General anti-counterfeiting technology has false proof antiforge, chemical material, physical security, digital technology and information anti-both at home and abroad
Pseudo-, packaging destructive structure is false proof and biological characteristic is false proof etc., and the purpose of these technologies is all to create a kind of business that can be false proof
Product are identified, but so far, all these technologies be all part solve antifraud marker in the uniqueness, readable that requires
Property, verifiability and with by protection commodity can bind sex chromosome mosaicism, in addition, all these technologies mostly do text on commodity counterfeit prevention
Chapter, cannot realize that low cost is cracked down on counterfeit goods.
The shortcoming of these anti-counterfeiting technologies is described as follows with deficiency：
The uniqueness of anti-counterfeiting mark：Most of commodity false proof marks are all because that processing technique is complicated, manufacturing technology is advanced,
Secrecy, causes anti-counterfeiting cost high and allows fake producer to hope and halt, if contrary technology is once divulged a secret or processing technology progress,
The level that fake producer copys is also higher than genuine piece, allows false proof manufacturer oneself all without distinguishable.In addition, complex manufacturing technology causes to prevent
Puppet can only be made by professional false proof company, due to the possibility of internal crime, objectively do not ensure that the uniqueness of anti-counterfeiting mark
Problem.
The readable and verifiability of anti-counterfeiting mark：Some anti-counterfeit commodities utilize the Nature texture and physical characteristics of materials come
Unique mark is manufactured, but cannot read or read complexity, cause to read equipment manufacturing cost costliness, it is impossible to which popularization is pushed away
Extensively.
Secondly, after false proof mark data reads, a kind of verification mode is exactly to compare with manufacturer commodity data database data,
Once can the validation database divulge a secret or privately prevent usurp (based on manufacturer be it is false proof ecology in shareholder), the result of checking
Can not fully prove the verity of commodity, thus this verification mode lose it is just.Another way is by setting in checking
In standby, the threshold value of preset false proof business men setting is judged, this method can only be done general because being not related to the characteristic of particular commodity
Adaptive verifies that threshold value is too high, can filter out genuine commodity, and the too low possibility for just having fraud is worse to be, it is impossible to prevent false proof
Manufacturer internal is committed a crime.
Anti-counterfeiting mark and the binding property by protection commodity：At present, anti-counterfeiting mark is if it were not for being pasted onto commodity interior packing
Upper (or integral with commodity packaging), otherwise be exactly to be physically held on commodity, as a part for commodity；Therefore, it is all of
Anti-counterfeiting mark, unless disposable anti-counterfeiting mark, can be separated with commodity violence itself, cannot solve repeatability makes
Problem.
Crack down on counterfeit goods with high costs：As anti-counterfeiting mark cannot ensure uniquely, checking data cannot be just, and anti-counterfeiting mark repeats profit
With etc. reason, above-mentioned anti-counterfeiting technology only makes an issue of on false proof, but cannot crack down on counterfeit goods, reason be evidence obtaining high cost,
Phenomenon of disputing over trifles is serious, and in actual life, anti-counterfeiting mark has become the magic weapon that fake products responsibility is escaped by manufacturer in fact, it is all of after
Fruit can only be undertaken by consumer.
Anti-counterfeiting cost is high：Anti-counterfeiting technology is higher, and internal control requirement is tighter, in addition to anti-counterfeiting technology cost itself, interior
Portion's management cost into geometric growth, therefore, the higher anti-counterfeit commodities of technology are more unsuitable for large-scale promotion.
False proof main body unicity：The strength of the single dependence manufacturer of false proof mode, is whole with enterprise's one's own antagonism at present
Individual unordered, exclusive concern with money, lacks sincere society, often unable to do what one wishes.

Read private key).
Second aspect, as shown in figure 8, consumer is during preservation or commodity in use, can be according to second-hand goods
Form transfers other consumers, and concrete transference has：
A, the information that can be transferred the possession of with typing, or for important commodity, maintenance can be recorded or according to the repair and maintenance stage
Use information etc. is recorded respectively.
B, the transfer of second-hand things of commodity be meant that and the digital properties rights and interests (commodity private key) of commodity transferred second-hand consumer,
Take the form of and recipient is transferred by the form of digital envelope, encryption.
A3, commodity counterfeit prevention and checking principle of tracing to the source
1. the anti-fake venting code of salesman verifies key element
Whether a, the anti-fake venting code outward appearance are damaged
B, the anti-fake venting code whether there is, if useWhether use time is correct
Whether the commodity that c, the anti-fake venting code are represented are sold by the distributor that production firm authorizes, and whether salesman
Authorize via distributor
Whether the commodity circulation chain that d, the anti-fake venting code are represented is unique
2. consumer's goods fake certification key element
Whether a, the fake certification code outward appearance are damaged
B, with the presence or absence of public key information corresponding with the fake certification code-phase
Whether the commodity that c, the fake certification code are represented had carried out fake certification, if it did not, write has verified that letter
Breath, if it has been experienced that showing proving time and relevant information.
3. fake certification code verifies principle
A, scanned by mobile phone app and read commodity manufacturer's information, serial number and the private key information.
B, mobile phone produce checking random number, and use private key signature.

A4, commodity are faked and false proof ecological analysis
1. production firm
Manufacturer itself fakes and correlation analysiss：
A, enterprises' production capacity are not enough, approve that by certain mode the commodity of other manufacturers can be with the goods markss pin
Sell, such case is not substantially to fake, and is a kind of commercial activity, and enterprise there are interests scheme, also risky, once consumer's sense
Feel commodity problem, or go wrong to marking business administration, cause commercial quality to glide, the lighter's brand names are damaged, and severe one is related to
And arrive legal responsibility.
B, enterprise because raw material supply it is not enough, or production management is improper, makes a false report raw material supply, false item authentication etc.
Deng, substantially nor enterprise fakes, but a kind of Enterprise Credit, commercial quality problem, if commodity raw material information record exists
In block chain, then by inquiring about block chain, by raw material, manufacturer reports, the mode of government offices' supervision is solved.
C, enterprise are for capital operation, or form is played tricks, and need to fabricate the sales volume of commodity, enterprise need simultaneously with
Logistics, distributor forge related data together, the most it is difficult to, in the handheld terminal of terminal consumer, generation, must be fabricated by enterprise
Valency cost is huge.
2. logistics provider
The mode of fraud：In transit, sudden huge profits destruction anti-counterfeiting mark, records anti-counterfeiting mark number, makes the false proof of vacation
Mark, because needing individual processing one by one, is limited by haulage time, route, and the possibility played tricks on a large scale is little, but
Can not exclude and play tricks individually.
The method of process：Loglstics enterprise is strict with according to this rule related logistics information write area block chain, while also
Further control measures can be taken, the method for enterprise's official seal strip of paper used for sealing is such as added a cover on van, big packing cratess.Because
Logistics data evidence obtaining is related to the responsible partys such as individual, once there is fraud situation, logistics company can prove one's own innocence.
3. distributor
Fraud mode：As logistics provider, need sudden huge profits to disassemble anti-counterfeiting mark, obtain commodity false proof mark number, make
In storehouse, large-scale fraud must be internal staff's crime in case place, or till trade intentionally, but because true commodity number
Amount is certain, and distributor itself can be obtained without interests, but can not exclude the imitation behavior of depositary management personnel smallest number privately.
Processing method：It is required that distributor gives block chain depositary management data is activation according to this requirement, furthermore it is possible to strengthen warehouse
Management, installs video monitoring, and warehouse personnel's discrepancy resignation system.Because the evidence obtaining of depositary management data is related to the responsibility master such as individual
Body, once there is fraud situation, distributor, depositary management personnel can prove one's own innocence.
4. profitability fake producer
Profitability fake producer is the personal or group that faked for the purpose of profit, from the point of view of the anti-fraud system described in method, this
Planting fraud needs to meet two conditions：One is before merchandise sales, or before the false product copied are sold.And commodity pin
Need to verify the legitimacy of distributor when selling, so fake producer cannot make a profit by selling.
The method sale, Validation Mode have prevented the possibility of profitability fraud, and false proof root is solved from interests motivation
This problem.
5. malice fake producer
So-called malice fake producer is referred to not for the purpose of profit, otherwise is exactly that rival disregards cost malice for it,
Otherwise be exactly personal resentment malice for it, both of these case belongs to non-commercial crime category；In addition, crime time, place are also only
Can be on logistics road or distributor's storehouse, Jing is analyzed above, and this probability is also substantially absent from.
Even if having, fake producer is also to be paid, the true business for obtaining with certain cost (the false commodity of manufacture replace genuine commodity)
Product oneself can not can only be used or collect in commercial type.
In sum, the method can be called to account from the production uniqueness of anti-counterfeiting mark, commodity circulation trackability, fake producer
Property, fake producer is profitless etc., and several aspects ensure that false proof effectiveness.
Subject identity during A5, commodity circulation is proved and management rule
Subject identity during commodity circulation, method have following requirement：
A, production firm adopt real-name authentication (issuing digital certificate by the e-commerce certification authority of authorized by state)；
B, logistics provider and distributor are network anonymous, manufacturer is responsible for reviewing
C, salesman, depositary management personnel are network anonymous, distributor is responsible for reviewing；
D, consumer's anonymity (real name is optional).
6th, low cost crack down on counterfeit goods according to and principle
In the method for anti-counterfeit, each main body responsibility is detailed perfectly clear, open, fair, reliable, and can review, concrete manifestation
：
Clearly, anti-counterfeiting mark involves anti-counterfeiting mark production firm to being responsible for by production firm, not for a, false proof main body responsibility.
B, cryptographic algorithm are simple, reliable, and the fake certification code self-generating based on asymmetric arithmetic rises, and anyone does not know
Road, has no way of copying.
C, commodity circulation phase data can be traced to the source, can be collected evidence.With PKI technologies, block chain technology guarantees that currency data can not be usurped
Change, non-repudiation.
Although d, logistics, distributor, salesman, depositary management personnel are network anonymous, by responsible party (production firm
And distributor) can review, otherwise, undertaken by responsible party.
Once e, have commodity fake, can be looked into by block chain and take commodity production and currency data, find problem source
Point.
By above description, no matter when, what stage there is commodity imitation behavior, consumer can determine in time
Responsible party, and counterindemnity is obtained, again without undertaking the loss that fake products brings, production firm can also pass through the party for consumer
Method safeguards the just rights of oneself.
