For one never typing for product back-tracing anti-fake user inquiring system database single product, upload
First enterprise of its information is often brand quotient (or brand proxy quotient) or manufacturer.Product is established in typing its information for it
Before resume (or later or simultaneously), need to assign it number.The number of single product is drafted can be by rule above-mentioned, this
Can be specifically following two situation in embodiment:
1, product is from provided with bar code, two dimensional code or digital number, at this point, what analysis and processing module was used by the enterprise
Code reader obtains the corresponding fixed value of digital number of the included bar code of the product or two dimensional code or enterprise's input, and from flowing water
Code pond obtains serial code at random, and fixed value adds serial code to be just used as in the number input system of the product;
2, product there is no bar code, which is the enterprise at bar code generation point, and the enterprise passes through its enterprise visitor at this time
Family end proposes bar code application to system, system can according to specified Rule bar code fixed value, and from serial code pond with
Machine obtains serial code, and the bar code that fixed value adds serial code that system is just used as to generate feeds back to the enterprise client, and enterprise can be with
It is invested on the product, and the fixed value adds serial code to be just used as in the number input system of the product.
Also, for the first case, in order to subsequent enterprise upload convenience, preferably, the enterprise should simultaneously to
It is proposed system proposes bar code application, and the corresponding bar code of the number of the product is fed back to its enterprise client by system, the enterprise
Industry can invest the bar code on the product.In this way, the enterprise of back upload information can be automatic by reading the bar code
Obtain the number of the product.Such processing mode is used in the present embodiment.
In addition, for having wrapped product, especially with multiple products and with the product of multi-layer packaging in packaging
The case where, the relationship for indicating above-mentioned packaging and product is fetched the present invention provides product/bale number chain.In particular, right
In there is the case where multiple products in a packaging, number is assigned to packaging and each product therein respectively, in each product
Number and its number for packing between establish the link respectively;The case where for multi-layer packaging, respectively to multiple packagings and wherein
Each product assign number, each product number and closest to its first layer pack number between establish chain respectively
It connects, is established the link between the number of multiple first layers packaging and the number for the overpack packed closest to first layer, with
This analogizes.It is illustrated below.
One case laughable, and packaging case number (CN) is KLC001, there is three bundles in one case, and every bundle has six tanks laughable.Product/bale number
Linking relationship be as follows:
Number KLC001, KLK001-003 and KL001-018 in table in first three column are all that bar code generates at point
To generating after system application, which is attached to each bar code in corresponding packaging and product for enterprise, specifically, number KLC001
It is attached on packing case, number KLK001-003 is attached to respectively on 3 bale packings, and number KL001-018 is attached on each laughable tank body.
Linking relationship between these numbers can be shown in systems by table as above.
The enterprise that bar code generates at point complete the number of the product to system typing after (before or while), in system
Product information relevant to the enterprise is passed, such as the enterprise is brand quotient, then uploads the brand message of the product, which is
Manufacturer then uploads the production information of the product.With the circulation of product, subsequent enterprise, such as common carrier, storage and sale
Quotient respectively uploads the transit information, storage information and sales information of the product.Finally this is formd in the database of system
The complete product resume of product.Product/packaging sales information is set forth in two columns after in table as above.
Any user inputs the number of product to be checked to analysis and processing module by user client as a result,, such as
By uploading the bar code on the product, analysis and processing module obtains from database associated with the number according to the number
Product resume, and showing, the i.e. product resume of the available product to be checked of user.Each user client can pacify
Mounted in the mobile terminal of each computer terminal or this mobile phone, PDA etc..Analysis and processing module can be installed on server, compared with
It is mounted on cloud server, can be serviced thereon from authentication module, database at same or different goodly.
For example, to the example of cola given above, by the number KL001 laughable to system input, this can be found
Laughable product resume, ginseng are seen the above table.Also, it is linked due to having between the number and the number KLC001 of packaging, passes through production
The number of product can obtain the resume with packaging simultaneously, as shown in the table:

2014/1/1 |
It sells |
In addition, analysis and processing module analyzes the product resume of acquisition, the true and false of product to be checked is judged, and will sentence
Disconnected result is sent to the user client.For example, product resume shows that the distribution state of the product is when not selling, this is to be checked
Product is judged as puppet.
In order to keep the judgement of analysis and processing module more accurate, analysis and processing module can obtain automatically inputs the number
Region where user client.For example, on computers if it is user client installation, its correspondence can be judged by IP
Physical location;If be mounted on mobile phone, thus article can be calculated by its current position of IP and GPS precise positioning
The physical distance a little with query point is sold, the foundation as identification.In addition, the user client being mounted on mobile phone may be used also
To obtain the longitude and latitude of mobile phone position by GPS, and retail shop's list at the longitude and latitude is provided accordingly, arranging for user
The retail shop of the commodity is bought in selection in table.
In order to keep the judgement of analysis and processing module more accurate, user can also be to be checked in inputting by user client
Ask purchase information of product, such as purchase ground, time buying, price and retailer etc.;User can also pass through user client
The product information subsidiary in input product to be checked is held, such as is printed on model, the batch, production of its product external or in packaging
Amount, grown place and/or production time etc..In this way, analysis and processing module is by these information and according to the product resume of number acquisition
It compares and analyzes, can more accurately judge the true and false of product to be checked, and send the user client for judging result
End.
Preferably, analysis and processing module determines the production from product resume associated with the number of the product to be checked first
The classification of product uses different analytical judgment methods for different classes of product, in particular:
1, for the exclusive mode of exclusive article.According to the photo in kind in its product resume, article identification manufacturer or a
It people's relevant information, assay certificate, items sold and resells information and analyzes and determines, such as:
Article identifies quotient: XX article evaluating center, is found in XX, scale XXX, links network address:www.XXXXXX.com
Items sold and resell relevant information:
The Beijing 2013-03-21 10:10- evaluating center XX is accredited as rare suet topaz
2013-03-28 14:07-XX express delivery order, transports Dali to
The Dali 2013-03-30 17:22- XX jade marketing center receives
The Dali 2013-04-01 08:50- XX stone marketing center's restocking sale
The Dali 2014-05-21 20:11- XX jade marketing center is sold
Article is resell and gives user B by 2014-06-22 07:13- user A
For meeting with photo, authentication information is reliable, sells and resell the complete reasonable product of record, it can be determined that it is
Very.In addition, historical query record can also be used as one of foundation of judgement.Analysis and processing module by the primary of identical product and
Repeatedly inquiry save in the database, as the product historical query record, generally include query time, inquirer,
The user client used and inquiry place.In addition, inquiry is inquired before shopping around and inquired after sale, analysis and processing module can be by them
Record is distinguished, wherein inquiry records the foundation judged as the true and false after sale.Such as the historical query record in upper example are as follows:
2014-05-22 07:13- user A logs in cell phone system inquiry, inquires place Dali
2014-06-12 09:33- user B logs in cell phone system inquiry, inquires place Beijing six directions
As can be seen that query time, inquirer and inquiry place are consistent with the product resume of the product, it is further true
The product of accepting is true.
2, for best brand of product or the franchise store schema of luxury goods.It is raw according to the product essential information in its product resume
Production, logistics, storage, sales information and historical query are recorded and are analyzed and determined, such as:
Product resume:
XX brand mobile phone, using the healthy and free from worry gorilla screen of the third generation, wear-resisting scratch resistance, true eight caryogamy set faster processing speed,
32G memory massive store ...
The Beijing 2013-03-21 10:10- XX foundries produce shipment
2013-03-28 14:07-XX express delivery order, it is chain to transport Shanghai XX mobile phone to
The Shanghai 2013-03-30 17:22- XX mobile phone is chain to receive
The chain restocking sale of the Shanghai 2013-04-01 08:50- XX mobile phone
XX mobile phone chain mobile phone in the Shanghai 2014-05-21 20:11- is sold
Historical query information:
2014-05-21 21:13- user A logs in cell phone system inquiry, inquires place Shanghai ever bright city
It is complete for product resume and be consistent, the product that historical query information is consistent with product resume judges that it is true.
3, for the non-designated retail store schema of chemical product and daily necessity.Believed substantially according to the product in its product resume
Breath, production, logistics, storage, sales information and historical query are recorded and are analyzed and determined, such as:
Product resume:
XX milk is brand under XX group, and the place of production region China X X, the luxuriant milk supply in temperate climate grassland is pure in prairie
Just, it is your trustworthy quality product ...
Date of manufacture 2013-03-21 10:10
Shelf-life 1 month
The Inner Mongol 2013-03-21 10:10- XX milk production base produces shipment
2013-03-22 14:07-XX express delivery order, transports Tianjin XX supermarket to
The Tianjin 2013-03-23 17:22- XX supermarket receives
The Tianjin 2013-03-01 08:50- XX supermarket restocking sale
Historical query information:
2014-05-21 21:13- user A logs in cell phone system inquiry, inquires place Pudong International Airport in Shanghai
It can be compared, be calculated according to the time of inquiry and the date of manufacture of product and shelf-life in such judgment method
Whether product is in good buying phase, and the foundation as true and false judgement.Thus it can determine whether that the product in this example is false, and its
Historical query information is not consistent with product resume also supports to judge that it is false.
4, for the batch commodity model of chemical product and daily necessity.According to the product information in its product resume, each area
The distribution situation in domain and historical query, which record, to be analyzed and determined, such as:
Product resume:
XX cigarette is that China X X cigar mill represents brand, under to possess nine kinds of different cultivars available ...
Production time
The Nanjing 2013-03-21 10:10- XX cigar mill produces shipment
2013-03-22 14:07-XX express delivery order, transports Jiangsu Yangzhou XX dealer to
The Jiangsu 2013-03-23 17:22- Yangzhou XX dealer distributes toward Yangzhou, Xuzhou, three ground of Suzhou
The distribution situation in each region: 200, Yangzhou, 900, Xuzhou, 100, Suzhou
Historical query record:
Each site polling situation: Yangzhou 100 times, Xuzhou 300 times, 50 times, Suzhou
It is complete for product resume and be consistent, the product that historical query information is consistent with product resume judges that it is true.
In addition, can not determine the true and false since system is possibly under partial picture, analysis and processing module is at this time with the side of question and answer
Formula inquires inquiry, the foundation that the answer that inquiry is provided judges as the true and false by user client, and question and answer may is that
Does is may I ask you to inquire for the first time?
Does is may I ask you the second-hand product bought?
Does is the bar code that may I ask in the product packaging of your purchase XXXXXX? Deng.
The bulk article that above-mentioned batch commodity model is related to carries lot number, larger per a batch of bulk article number,
And its purchase volume is larger, to each single product assign its unique number be it is unpractical, it is included that its is usually taken at this time
Lot number has the characteristics that number is not unique as number;Also, the same batch products of this kind of product may be distributed to not
Same area.These problems are all that the analytical judgment work of analysis and processing module brings adverse effect.Below to this quasi-mode
A kind of quantitative analytical judgment method is further provided, this method is based on historical query record and product resume, judges to mark
Standard is that a possibility that product is counterfeit or inferior quality goods is bigger if the site polling number of a certain number is more.In particular:
The weighted sum of the first value compared and the second value from outside relatively will be internally sourced as described in judgement
Product whether be counterfeit or inferior quality goods standard;Wherein, the first value is equal to site polling number/region commodity number × regulation coefficient, the
Two-value is equal to the total inquiry times of site polling number/region commodity number -/total commodity number;When the weighted sum of the first value and second value
Greater than 1, judge the product for counterfeit or inferior quality goods.
Use the user inquiring system and method for being previously described for back-tracing anti-fake, in particular, the number of product to be checked
Be input to analysis and processing module by user client, the time that analysis and processing module inputs the number as query time,
Using the geographical location where the user client as inquiry region;Analysis and processing module is by above-mentioned query time and inquiry
Domain is saved in database to generate the query history record to the number, and the number is associated with query history record.
Also be stored with product resume associated with the number in database, include in product resume the corresponding multiple products of the number and
Geographical location where these products difference.As previously mentioned, the geographical location where user client can by IP (for
Be mounted on the user client of the mobile terminal of such as mobile phone, can also be according to its GPS positioning) obtain geographical position where it
It sets, in the present embodiment, the dividing unit in geographical location is city, such as Suzhou City, Yangzhou etc..
Analysis and processing module is by calculating the inquiry time occurred in inquiry region with the number associated query historical record
Number, and as site polling number;Analysis and processing module with the number associated query historical record by being calculated
To total inquiry times of the number;Region commodity are calculated by product resume associated with the number in analysis and processing module
Several and total commodity number, wherein commodity number in region is that geographical location is the number for inquiring the product of region, total commodity in multiple products
Number is the total number of multiple products.
Preferably, being used for user same in the short time same when obtaining site polling number from historical query record
Multiple inquiry of the same area to same number the case where, site polling number is designated as 1 time one user client;For
In short time same user using different user clients multiple inquiry of the same area to same number the case where, region
Inquiry times are designated as 1 time.It the use of the user that user client is inquired should not be anonymous i.e. in the present embodiment, and should
Username and password is obtained by registration, and by that could use user client after verifying, the record used is just saved
For historical query record.Wherein, the short time is 1 day.In addition, the weight of regulation coefficient, the weight of the first value and second value should
It is set according to the type set of product, and after being investigated preferably by actual market.Generally, regulation coefficient is taken as 1, first
The weight of value is 30%, and the weight of second value is 70%.
Above-mentioned this analytical judgment method is illustrated below by way of one.
XX board cigarette, one case includes 20, and every includes 12 cigarette packages, so including for one case 240 cigarette packages.240 packets are fragrant

First value=100/40*1=250%
Second value=100/40-102/240=207.5%
Weighted sum=250%*30%+207.5%*70%=220.25% of first value and second value,
The probability for having 220.25% is fake products, so being finally determined as vacation.
Situation 2:
Shanghai inquiry times 2, Beijing inquiry times 100 inquire user in Shanghai
First value=2/40*1=5%
Second value=2/40-102/240=-37.5%
The weighted sum of first value and second value=5%*30%+ (- 37.5%*70%)=- 24.75%
The probability for having -24.75% is fake products, so being finally determined as true.
Situation 3:
Shanghai inquiry times 21, Beijing inquiry times 100 inquire user in Shanghai
First value=21/40*1=52.5%
Second value=21/40-121/240=2.1%
Weighted sum=52.5%*30%+2.1%*70%=17.22% of first value and second value
The probability for having 17.22% is fake products, so being finally determined as true.
