Step S10: the identification two dimensional code of the factory information comprising product is generated.
Factory information described in this step includes at least the information such as the place of production, manufacturer, date of manufacture, ingredient, quality.Know
Unique identification of the other two dimensional code as product is the passage key for being connected to product and block platform chain.User can be somebody's turn to do by scanning
The factory information of two dimensional code acquisition product.The identification two dimensional code posts up in the outer packing of product, uses convenient for scanning.
Step S20: the logistics information of product typing in each logistics node is received, and is created corresponding with each logistics information
Website block.
Logistics information described in this step includes logistics odd numbers, address, arrival time, issues time etc., further
Including carrier vehicle information, sender's information etc..Creation website block will identify two dimensional code and website to store logistics information
Block associations, i.e., after product enters logistics chain, logistics node terminal passes through scanning recognition two dimensional code first and sets up logistics
Nodal terminal is linked with block platform chain, and the logistics information of logistics node where product is then corresponded to the corresponding website of typing
In block, also with website block associations, consignee can be obtained the identification two dimensional code when receiving by scanning recognition two dimensional code
Take the logistics information in website block.
Step S30: receiving the satellite short message that logistics node terminal is issued when network signal intensity is lower than preset value, and

In this step, logistics node terminal refers to the end PC with data acquisition and transfer function, mobile phone terminal, plate electricity
Whether brain etc. can be lower than preset value to determine whether having data according to the network signal intensity of itself before data upload
Transmittability, the preset value need to determine according to logistics node terminal's signal reception ability, optional -113dBm~-80dBm.
The remote transmission of data, logistics node can not be normally completed when its network signal then represents the logistics node terminal lower than preset value
Terminal, which will be sent using the satellite short message technology of Beidou satellite navigation and positioning system to block chain, has specific time stamp and ground
The satellite short message of coordinate is managed, block platform chain receives the satellite short message and corresponding creation verification information block is defended to store this
Star short message, satellite short message are not needed using network transmission, even if logistics node terminal fails to upload logistics immediately because of suspension

Reliable logistics information is obtained, and confirms that product have passed through the satellite short message of certain logistics node.
The present embodiment utilizes the satellite short message technology of Beidou satellite navigation and positioning system, believes in the logistics of certain logistics node
Supplementary enters the timestamp and geographic coordinate information of the logistics node when ceasing because of suspension missing, to enter the object as product
The evidence of node is flowed, so that the missing of logistics information be avoided to cause the imperfect of product traceability data, it is anti-fake to improve product traceability
As a result confidence level.Further, it is short to receive the satellite that each logistics node terminal is uploaded when product reaches the logistics node
Message can further increase the logistics information confidence level of logistics node terminal upload in this way.
Furthermore to prevent product from being exchanged during transportation, for the present invention in product turnout, outer packing is equipped with the
One three-dimensional tag and the second three-dimensional tag, the first three-dimensional tag and the second three-dimensional tag include the ink mixed and anti-fake
Particle, false proof particle quantity are to be randomly generated, and guarantee the uniqueness of three-dimensional tag, on this basis, in each three-dimensional tag also
A degree of deformation can occur at high temperature for the thermo-sensitive material comprising presetting content, thermo-sensitive material, such as generate raised font, figure
Sample etc., can be visible for naked eyes.First three-dimensional tag and the second three-dimensional tag are respectively arranged at the outer of product, inner packing, outsourcing
Filling to check and shoot at any time, and inner packing is then fixed with product always, and the present invention passes through is arranged inside and outside double solid on product
Label adds the thermo-sensitive material of preset ratio in two three-dimensional tags, passes through the first three-dimensional tag of monitoring and the second three-dimensional tag
Strain image compare and can determine that the true and false of product.
Further, the content ratio of thermo-sensitive material is unequal in the first three-dimensional tag and the second three-dimensional tag, therefore
The two has different deformation quantities, and especially when variation of ambient temperature is larger, deformation difference between the two is at any time increasingly
Greatly.Such as when the logistics information of product shows that the product have passed through high temperature area, theoretically the first three-dimensional tag and second three-dimensional
Deformation quantity difference between label should be relatively large, and consignee is enabled directly visually to identify its difference enough, if both practical
Between deformation quantity difference it is smaller, then illustrate that the product is practical and without high temperature area, the product very maximum probability be by
The adulterant stealthily substituted.
On the basis of the said goods Anti-false packing structure, the present invention is based on the antifake method for products of block chain is also further
Ground includes the following steps, as shown in Figures 2 and 3:
Step S50: receive the first initial pictures of the first three-dimensional tag that product is arranged in its outer packing in shipment and
Second initial pictures of the second three-dimensional tag being arranged in inner packing, and create and the first initial pictures and the second initial pictures phase
Corresponding original block.
In this step, product is equipped with the first three-dimensional tag in shipment in its outer packing, and setting second is vertical in inner packing
Because of the parameter change of local environment macroscopic deformation can occur for body label, the first three-dimensional tag and the second three-dimensional tag.
Such as: in the circulation of the product, it will be influenced by external environments such as such as temperature, first on product external packaging
The second three-dimensional tag on three-dimensional tag and inner packing can then generate corresponding physical deformation.Especially note that the inner packing of product
It is generally all attached on product, can only be shifted with the transfer of product, if fruit product is exchanged, then corresponding second three-dimensional tag
Also it can be exchanged together.Block platform chain obtains the first three-dimensional tag and the second three-dimensional mark that manufacturer's terminal uploads in this step
The initial pictures in shipment are signed, and are stored in the original data wherein by creation original block.
Step S60: the first strain image of product first three-dimensional tag in acceptance is received, and is created and the first deformation map
As corresponding first acceptance block.
In this step, product shoots the one of the first three-dimensional tag by consigning to consignee, consignee after logistics transportation
Strain image, the first strain image obtained at this time are the final strain image of the first three-dimensional tag.First strain image is deposited
It is stored in block chain in corresponding first acceptance block.
Step S70: the first initial pictures, the second initial pictures and the first shape are read from original block and the first acceptance block
Become the corresponding image data of image, generates reference picture corresponding with the second three-dimensional tag according to image data and be sent to and receive
People's terminal.
In this step, after consignee opens outer packing, the practical shape of the second three-dimensional tag in inner packing can be observed directly
Become image.And the second three-dimensional tag theoretically have passed through same path and same environmental condition with the first three-dimensional tag, because
This, the deformation of the two should have common point, and block platform chain can be according to the first initial pictures, the second initial pictures and the first shape
Become the corresponding image data (such as deformation quantity) of image, the final strain image that obtains the second three-dimensional tag theoretically and should present,
Using the anti-fake reference picture as the practical strain image with the second stereo-picture.Citing: the first three-dimensional tag and the second solid
With the anti-fake material of same amount in label, such as thermo-sensitive material, the two is in its deformation degree after same environmental condition
Should be identical, thus as the final strain image of the second three-dimensional tag compared with its second initial pictures obtained from physical deformation
Amount, should the physical deformation amount phase obtained from the first strain image of the first three-dimensional tag is compared with its first initial pictures
Deng, therefore calculate and simulate the reference picture of the second three-dimensional tag.Alternatively, in the first three-dimensional tag and the second three-dimensional tag
Anti-fake material component ratio is unequal, and the two is proportional, then similarly, can be according to the first initial pictures, the second initial pictures
The second solid is calculated in the ratio of anti-fake material in image data corresponding with the first strain image and two three-dimensional tags
The theoretical deformation quantity of label simultaneously generates reference picture, for example, the thermo-sensitive material ratio in the first three-dimensional tag and the second three-dimensional tag
Example is 1:2, and the first three-dimensional tag and the second three-dimensional tag its surface in product turnout all have a round protrusion (or for light
Sliding surface), which is 1mm；After logistics transportation, for the first three-dimensional tag in acceptance, the circle on surface is prominent
It plays radius and becomes 3mm, theoretically its surface should form the round protrusion that radius is 1+ (3-1) * 2=5mm to the second three-dimensional tag.
This example is only how to give expression to according to the first initial pictures, the second initial pictures and the corresponding image data life of the first strain image
At the theoretical procedure of reference picture corresponding with second three-dimensional tag.In practice, specific deformation direction (height side
To, along planar diffusion direction etc.) and deformation function etc., need to be determined by the physical characteristic of anti-fake material, as generating with reference to figure
The reference data of picture.
After block platform chain simulates the reference picture of the second three-dimensional tag according to above-mentioned image data, by the reference picture
It is sent to consignee's terminal, it is real so that consignee's terminal compares the reference picture and whether actual third strain image is consistent
Consistent preliminary judgement when now to product whether with shipment.The common intelligence of the consignees such as consignee's terminal, that is, mobile phone, computer is eventually
End.
The second three-dimensional tag and the first three-dimensional tag is respectively set in the present embodiment in the exterior and interior packing of product, by appearance
The tracking of the first three-dimensional tag on the product external packaging easily obtained and deformation analysis simulate inside outer packing and adhere to
In the deformation reference picture of the second three-dimensional tag in product inner packing, and it is sent to consignee's terminal, to help consignee
Terminal judges whether the practical deformation results of second three-dimensional tag consistent with analog result, if according to consignee visually observe less than
Inner packing where difference between the two then represents second three-dimensional tag is not replaced during Product transport, that is, is produced
Product are not replaced during transportation, consistent when product when receiving is with shipment, and on the contrary then product was replaced, to judge
The true and false of product out.This method fundamentally solves the problems, such as that product is stealthily substituted during transportation.
In a preferred embodiment, as shown in figure 3, the antifake method for products based on block chain further include:
Step S80: the second strain image of product second three-dimensional tag in acceptance is received, and is created and the second deformation map
As corresponding second acceptance block.
The second strain image i.e. practical strain image of the second three-dimensional tag, the practical strain image are shot simultaneously by consignee
It is stored in the second acceptance block of block chain.
Step S90: the image similarity of reference picture and the second strain image is calculated.
Step S100: if image similarity is less than preset threshold, product when determining acceptance and product when shipment are not
Together.
In this step, the similarity degree that image similarity calculating is mainly useful for content between two images is beaten
Point, the close degree of picture material is judged according to the height of score.In the prior art for the similarity between two images
There is more mature algorithm, e.g., calculate separately the histogram of two images, then HistA, HistB calculate two histograms
Normalizated correlation coefficient (Pasteur's distance, histogram intersection distance)；Or further, the fritter of transverse and longitudinal is divided into image, then
For each partitioned searching most matched histogram therewith.It calculates the similarity of two images, it is corresponding to have incorporated histogram
The information of position.For another example the image similarity based on characteristic point calculates, specifically: every piece image has the characteristic point of oneself,
These characteristic points characterize some positions important in image, and usually more commonly used has Harris angle point and Sift feature
Point.So obtained image angle point is compared, if similar angle point number is more, it is considered that this two images
Similarity degree it is higher.The similarity algorithm of image is the prior art, therefore is seldom repeated.
If image similarity is less than preset threshold, product when determining acceptance is different from product when shipment；If image
Similarity is greater than or equal to preset threshold, then product when determining acceptance is identical as product when shipment.
In the present embodiment, the preferred 0.8-1.0 of preset threshold, wherein " 1.0 " represent the practical deformation map of the second three-dimensional tag
Picture, i.e. the second strain image, with the reference picture simulated according to the deformation quantity of the first three-dimensional tag, the two is completely the same,
" 1.0 " are peak.The similarity of two images represents second three-dimensional tag more than or equal to 0.8 and is transporting with the first three-dimensional tag
It experienced identical environmental condition in defeated engineering, that is to say, that product does not leave outer packing during transportation, eliminates product
A possibility that stealthily substituting shows that the product is genuine piece；Conversely, then illustrate that product has left outer packing during from shipment to harvest,
The second three-dimensional tag when the second three-dimensional tag puted up in product inner packing is not former shipment.Block chain is directly by second
Strain image and reference picture carry out similarity calculation and obtain the judgement of authenticity of products as a result, the judgement result can be sent directly to
Consignee's terminal exempts the fake certification process of consignee's terminal, relatively more convenient and efficient.
At this point, being arranged on product external packaging, there are two marks: identification two dimensional code and the first three-dimensional tag, in product inner packing
Equipped with the second three-dimensional tag, the present embodiment has triple antiforge functions: 1) consignee can be obtained by scanning recognition two dimensional code and be produced
The factory information and logistics information of product are realized preliminary anti-fake；2) consignee or harvest terminal are according to the first strain image and finally
The first strain image that one logistics node (usually nearest from a consignee express delivery point) uploads compared to pair as a result, sentencing
It is consistent when whether stopping pregnancy product and its outer packing are with shipment；3) block platform chain compares the second strain image and reference picture, according to
Similarity between the two is consistent when whether judging product and its inner packing with shipment.This three kinds anti-fake, especially third step, energy
Enough effectively playing prevents product during transportation by the case where being changed to fake products of stealthily substituting, to play effective antifalse effect.
In a preferred embodiment, the antifake method for products based on block chain further include: it is first vertical in each logistics node to receive product
The third strain image of body label, and process block corresponding with each third strain image is created, third strain image includes
Shooting time stamp and geographical location information.
It in this step, needs during product stream by multiple logistics nodes, when by each logistics node, first is three-dimensional
Label generates corresponding physical deformation, this step be to acquire the first three-dimensional tag in the third strain image of each logistics node,
And each third strain image is corresponding in turn to each logistics node and is stored, the same anti-counterfeiting information as product.
In the present embodiment, third strain image includes when shooting timestamp and geographical location information, third deformation
Image can be stored in simultaneously in corresponding website block with logistics information, can also create new mistake when in logistics website suspension
Journey block, and upload is delayed in corresponding process block.Even if therefore in the logistics node logistics information can not instant typing,
It is delayed after network link with specific timestamp and geographical location information in the third strain image of upload, block chain can root
The authenticity of the third strain image is judged according to the information, to guarantee the information authenticity and entire block of the logistics node
The integrality of data in chain reduces block chain technology to the dependence of internet.
In a preferred embodiment, the antifake method for products based on block chain further include:
Identification two dimensional code is associated with process block.
Identify that two dimensional code is associated with the first strain image and logistics information simultaneously, consignee or other users can be somebody's turn to do by scanning
The third strain image and logistics information that two dimensional code obtains the factory information of product, each logistics node generates are identified, thus entirely
The every terms of information of the bought product of the understanding of aspect.
The present invention also proposes a kind of product false proof device based on block chain, as shown in figure 4, the device includes:
Two-dimensional code generation module 10, for generating the identification two dimensional code of the factory information comprising product；
Website block creation module 20, for receiving the logistics information of product typing in each logistics node, and create with

The satellite short message of upload, and create verification information block corresponding with the satellite short message, the satellite short message packet
Include current time stamp and geographical coordinate；
Relating module 40 is used for the identification two dimensional code and the website block and verification information block associations.
In the present embodiment, two-dimensional code generation module 10 generates the identification two dimensional code comprising product export information as product
" identity card ", user can establish linking between product and block platform chain by scanning the identification two dimensional code.Website block wound
It models block 20 and creates corresponding website block, the corresponding logistics node of each website block, for storing up for each logistics node
Deposit logistics node terminal (the i.e. mobile phone.The smart machines such as computer) upload product stream information, verification information block create mould
Block 30 is used to receive the satellite short message of logistics node terminal upload when the network signal intensity of logistics node terminal is too low,
Using the supplement as the logistics information lacked under offline condition, the integrality and confidence level of product traceability data are improved.Association
