Example one
Fig. 1 is a schematic flowchart of a method for querying product traceability information according to an embodiment of the present invention, which is applicable to a scenario where traceability information of a product is queried, and the method can be executed by a device for querying product traceability information, and the device can be implemented in a software and/or hardware manner and can be integrated on a server.
As shown in fig. 1, a method for querying product tracing information according to an embodiment of the present invention includes:
s110, receiving a tracing query instruction of a target product, wherein the tracing query instruction carries a graphic code corresponding to the target product.
The tracing query instruction is an instruction for querying the tracing information of the target product. The graphic code refers to a graphic or a pattern with identification. The graphic codes corresponding to different products are different, and the target product in the embodiment corresponds to the unique graphic code. Alternatively, the graphic code may be printed on a packaging box for packaging the target product, or may be printed in an entity of the target product, which is not limited herein. Preferably, the graphic code is printed in the entity of the target product. Optionally, the graphic code corresponding to the target product may be a barcode, a two-dimensional code, or a microscopic graphic unit image that is not physically copied, and the like, which is not limited herein. Specifically, the microscopic graphic element image is a non-open source technology, and only an authorized enterprise can print the microscopic graphic element image, so that the target product is a genuine product as long as the microscopic graphic element image exists on the target product and the tracing information is inquired from the microscopic graphic element image. It should be noted that the microscopic graphic unit image is generated by a special non-open source algorithm, has a huge database, can store and record information, meets the requirement of one object and one code in product tracing, and has strong anti-counterfeiting, anti-copying and anti-destruction capabilities. The microscopic graphic unit image is used as an informatization tracing carrier of a physical product, and the tracing safety and effectiveness are greatly guaranteed. Specifically, in the micro graphic unit image, a plurality of dot units are arranged, each dot unit is small and is between 30 and 60 micrometers, the plurality of dot units form the identification unit, and the area of the minimum identification unit is 3 x3 mm. Therefore, a plurality of identification cells are arranged in the generated micro graphic unit image, even if a large area is damaged, only 3 x 3mm of area is left to be effectively read, and the micro graphic unit image has stronger anti-destructive performance compared with the traditional two-dimensional code and the traditional bar code. Referring to fig. 2, fig. 2 is a partially enlarged view of a micro pattern unit image according to the present embodiment. As can be seen from fig. 2, the partially enlarged view 111 of the microscopic pattern unit has a plurality of dot units, and the plurality of dot units constitute one recognition unit.
In an optional embodiment, in this step, after the application APP of the mobile terminal scans the graphic code corresponding to the target product, the mobile terminal packs the graphic code into the trace-back query instruction, and the server may receive the trace-back query instruction carrying the graphic code corresponding to the target product. In this embodiment, the mobile terminal includes, but is not limited to, a mobile phone, a tablet, a dedicated recognition device, and other terminals that have a camera function and can recognize a graphic code.
And S120, acquiring one or more certificate storing numbers associated with the graphic codes.
The verification number refers to an identification number generated by the block chain system after the tracing information is stored in the block chain system, and is used for inquiring the tracing information. In this embodiment, the number of the certificate storing numbers may be one or more, and is not limited herein.
In this step, specifically, when the trace back information is stored and the certificate storing number is returned by the block chain system, the graphic code and the certificate storing number are stored in an associated manner, so that when the trace back information needs to be queried, one or more certificate storing numbers associated with the graphic code are obtained.
S130, inquiring the tracing information of the target product in a block chain system according to the certificate storing number.
In this step, specifically, after the certificate storing number is sent to the block chain system, the block chain system queries the trace back information in the corresponding storage block according to the certificate storing number, and returns the trace back information to the mobile terminal that queries the trace back information for display. Optionally, the tracing information may be stored in the block chain system in a manner of text, picture, video, or web page link. Optionally, the blockchain system may include a higher-level company, an industry association, and a government supervision department, and may also add a certain node in the blockchain to supervise and supervise the traceability information of the blockchain system product, thereby ensuring that the information security is supervised. Meanwhile, the safety of the online block chain technology also ensures the credibility of the code scanning result of the offline physical product. The traceability information includes, but is not limited to, basic information of the target product, source origin, production line, production team, production time, warehouse entry and exit time, distribution information of dealers at different levels, code scanning and query time and location of the consumer, and is not limited herein.
Specifically, when the graphic code is a microscopic graphic unit image, whether the target product is a genuine product can be judged according to the microscopic graphic unit image. Specifically, the determination can be made by the following method:
extracting image characteristics of the microscopic graphic unit image; calling the standard image corresponding to the microscopic graphic unit image from a database to extract the image characteristics of the standard image; comparing the image characteristics of the microscopic graphic unit image with the image characteristics of the standard image to obtain a comparison result, wherein the comparison result indicates the ink diffusion proportion of the printed microscopic graphic unit image; judging whether the ink diffusion proportion is larger than a preset proportion or not; when the ink diffusion proportion is larger than the preset proportion, prompting the user that the target product is forged; and when the ink diffusion proportion is less than or equal to the preset proportion, prompting the user that the target product is a genuine product.
Specifically, the image feature of the micro graphic element image may be the thickness of each dot element in the micro graphic element image. Similarly, the image characteristic of the standard image is the thickness of each dot unit in the standard image. And comparing the image characteristics of the microscopic graphic unit image with the image characteristics of the standard image to obtain the ink diffusion ratio. Illustratively, the thickness of the dot cell of the image feature of the microscopic graphic cell image is a1, and the thickness of each dot cell in the standard image is a2, the ink spreading ratio may be (a1-a2)/a 2. When the ink diffusion proportion is larger than the preset proportion, the user is prompted that the target product is forged, and when the ink diffusion proportion is smaller than or equal to the preset proportion, the user is prompted that the target product is a genuine product. Alternatively, the preset ratio may be 10%. Alternatively, there may be a point where the ink spreading ratio is greater than a preset ratio, and the target product is considered counterfeit.
Specifically, when printing a microscopic pattern unit image, a phenomenon of ink spreading inevitably occurs, but a certain degree of ink spreading is acceptable. If someone wants to forge the micro graphic unit image by copying, because the micro graphic unit image has been diffused to a certain extent when printed for the first time, if someone copies the micro graphic unit image to forge the micro graphic unit image, the micro graphic unit image is further diffused on the basis of the first diffusion when printed, whether the target product is a genuine product can be determined by judging the ink diffusion ratio, so that whether the target product is the genuine product is identified by using the micro graphic unit image, and a good anti-counterfeiting effect is realized.
Specifically, when the authenticity of the target product is judged according to the microscopic graphic unit image, the following method can be used:
the microscopic graphic element image is acquired and attempts are made to resolve the coding information it contains.
When the coding information contained in the micro graphic unit image can be correctly analyzed, the sizes of all code points in the micro graphic unit image are respectively calculated. Illustratively, when n code points are included in the micro graphic unit, the size of the n code points is calculated as X1, X2, and X3 … Xn, respectively, where the size of a code point refers to its area.
According to the formula of average value calculation
Calculate the average size of these n code points:
M＝(X1+X2+X3+…+Xn)/n。
comparing the average value M with a predetermined code corresponding to the coding informationThe average value range of the point size, when M is in the preset average value range of the code point size, the formula is calculated according to the variance
The variance of the n codepoint size values is calculated:
s2＝((M-X1)2+(M-X2)2+(M-X3)2+…+(M-Xn)2)/n。
comparing the calculated variances s2A predetermined threshold, variance s, corresponding to the coding information2If the value is less than or equal to the threshold value, the target product is true, otherwise, the target product is counterfeit.
Wherein, the coded information can be understood as the product serial number corresponding to the microscopic graphic unit image. Optionally, whether the coding information corresponding to the microscopic graphic unit image exists or not can be searched in the database through the microscopic graphic unit image, and if the coding information exists, the coding information can be analyzed. The encoded information can be analyzed, and the encoded information is correct and exists, but the microscopic graphic unit image is not represented, namely, the microscopic graphic unit image is genuine, and possibly, the microscopic graphic unit image is printed by a bad merchant through other methods. The method comprises the steps of inquiring a preset code point size average value range corresponding to coding information and a preset threshold value corresponding to the coding information through the coding information, combining the code point size of an actual microscopic graphic unit image, calculating an average value of n code points through the steps, comparing the average value of the n code points with the preset code point size average value, calculating the variance of the n code point size values when the average value of the n code points is within the preset code point size average value range, and calculating the obtained variance s2Comparing with a preset threshold value when the variance s is2When the average value of the n code points exceeds the preset code point size average value range or the variance s, the target product is judged to be true, and when one of the steps is not met, the target product is judged to be forged, namely the coded information cannot be analyzed, and the average value of the n code points exceeds the preset code point size average value range or the variance s2And if the microscopic graphic unit image is larger than the preset threshold value, the target product is counterfeit, so that whether the microscopic graphic unit image is counterfeit or not is determined.
In this embodiment, since the trace-back information is stored in the block chain system, the queried trace-back information is real and has no tampering. In addition, the microscopic graphic unit image is printed on the entity of the target product, so that the target product cannot be copied in a real object manner, and when the tracing information of the target product can be inquired, the target product is indicated to be a genuine product. And the safety of the online and offline full chain tracing of the product is ensured by combining the printed microscopic graphic unit image of the entity of the target product below the line and the storage of the online block chain system.
According to the technical scheme of the embodiment of the invention, a tracing query instruction of a target product is received, wherein the tracing query instruction carries a graphic code corresponding to the target product; acquiring one or more certificate storing numbers associated with the graphic codes; and inquiring the tracing information of the target product in the block chain system according to the certificate storing number, wherein the inquired tracing information is real and has no tampering as the tracing information is stored in the block chain system, so that the technical effect of improving the authenticity of the inquired tracing information is achieved.
