Detailed Description
In order to make the present application solution better understood by those skilled in the art, the following description will clearly and completely describe the technical solution in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
The terms first, second and the like in the description and in the claims of the present application and in the above-described figures, are used for distinguishing between different objects and not for describing a particular sequential order. Furthermore, the terms "comprise" and "have," as well as any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.
Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. The appearances of such phrases in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. Those of skill in the art will explicitly and implicitly appreciate that the embodiments described herein may be combined with other embodiments.
When in production, manufacturers can attach two-dimension codes on the packages, record the information such as production time, production place, raw material sources, detection reports and the like, and upload the information to the server. In addition, parameters such as temperature, humidity and the like of the fresh food monitored in the transportation process can also be updated to the database. When the consumer purchases, the consumer can acquire the relevant information of the fresh food, such as production time, production place, quality guarantee period, detection report and the like, through scanning the two-dimensional code, so that the consumer can know the real situation of the food and can avoid purchasing unqualified food.
The existing method for tracing the product based on the two-dimension code realizes tracing and anti-counterfeiting of the product by improving an encryption algorithm. However, the method does not consider the characteristic of the short-period perishable product on time sensitivity, and does not fuse the time sensitivity into the process of generating the two-dimensional code and acquiring the information based on the two-dimensional code, so that the traceability and the information sharing system for the short-period perishable product are poor in adaptability to the product.
In view of the above, the present invention provides a method and apparatus for generating a two-dimensional code, and a method and apparatus for acquiring information based on the two-dimensional code.
Fig. 1 is a flow chart of a two-dimensional code generating method according to an embodiment of the present invention.
Referring to fig. 1, the two-dimensional code generating method includes:
s101 obtains first information characterizing a product feature, the first information including numbers and letters.
The first information characterizing the product features at least comprises batch information of the product, wherein the batch information at least comprises production time in a digital form and batch features in an alphabetical form. Typically, the production time is at least accurate to the production date, i.e. the production time comprises eight digits consisting of four digits production year, two digits production month, two digits production date. An example is 20230330M for a yogurt product based on the batch information formed in the format described above. For shorter cycle products, the production time is further accurate to the moment, i.e. on the basis of the above eight digits, it is also possible to include two digits production hours, two digits production minutes and two digits production seconds.
S102, respectively extracting numbers and letters in the first information, reordering the numbers in the first information to be used as first parameter values, and reordering the letters in the first information to be used as second parameter values.
Because the uniform resource locator is explicit address data, the digits and letters in the first information are reordered for improved security. In some further embodiments, the reordered numeric strings and alphabetic strings are processed for feature values, respectively, and the processed information is used as the first parameter value and the second parameter value.
In some embodiments, the reordering rule for reordering the numbers and letters in the first information may be changed with time, and the reordering rule adopted by the reordering rule may be written in the two-dimensional code in combination with other information. In the analysis process, a reordering rule is determined by analyzing the reordering identifier obtained by the other information in the two-dimensional code, and the reordering rule is used for processing the first parameter value to obtain a character string which represents the production time in the first information so as to be used for calculating the time interval in the subsequent step.
S103, forming a uniform resource locator of a corresponding address of the product based on at least the first parameter value, the second parameter value and the third parameter value; the third parameter value includes a time at which the uniform resource locator of the address was formed.
It will be appreciated that the first parameter value, the second parameter value and the third parameter value form key value pairs in the query parameter of the uniform resource locator. In addition, the first parameter value, the second parameter value and the third parameter value do not restrict the path part in the uniform resource location, and do not restrict the segment specified by the anchor point if necessary. After the three parameters are determined, the three parameters are added into the query parameters as key value pairs, and are converted into character string formats to be spliced into uniform resource locations corresponding to the products.
The third parameter value includes a data structure of a time at which the address uniform resource locator is formed in correspondence with a data structure of a production time of the product. Continuing with the above example of a yogurt product, the lot information of the product is 20230330M and the production time is 20230330, and the data structure of the time of forming the address uniform resource locator included in the third parameter value of the yogurt product is also an eight-digit number consisting of four-digit year of production, two-digit month of production, and two-digit day of production. For shorter period products, such as tens digits with production time accurate to production hours, twelve digits with production time accurate to production minutes, or fourteen digits with production time accurate to seconds, the data structure of the time of the corresponding uniform resource locator is consistent with the data structure, which is the corresponding tens digits, twelve digits, or fourteen digits.
And displaying the corresponding data of the product on the address corresponding to the uniform resource locator so as to be checked after the consumer or supervision scans the two-dimensional code and verifies. The corresponding data of the product comprises information of a production stage before the generated two-dimensional code is printed and information of a transportation and sales stage after the generated two-dimensional code is printed. The information in the production stage is directly updated to the address after the address corresponding to the uniform resource locator is generated, and the information in the transportation and sales stage is uploaded to a database in real time in each subsequent environment and updated to the address.
Illustratively, the information of the production stage before the generated two-dimensional code is printed, such as basic information, lot information, supervision spot check, sunshine factory, brand propaganda, and the like. Taking a certain yogurt product as an example, the basic information includes: product name, business name, shelf life, specified unit, commodity bar code, etc.; the batch information includes: business name, unified social credit code, inspection report, etc.; the supervision spot check comprises: current batch spot check report, other batch spot check report, etc.; the solar plant includes real-time video of the production line that produced the product; the brand promotion then includes a corresponding graphic or food description of the business of the product.
Illustratively, the information of the transportation sales stage after the generated two-dimensional code is printed, such as transportation information, sales information, and the like. Typical shipping information includes: real-time transportation conditions such as transportation temperature, humidity and the like, and logistics information such as starting point position and time, end point position and time, passing transit position and time and the like. The sales information includes sales channels, time, and the like.
It should be noted that, the data related to the product includes time data of multiple stages, and the time data of the multiple stages is used as an auxiliary verification mode in the process of scanning the two-dimensional code for inquiring, so as to timely identify and avoid website tampering or other information vulnerabilities. Of course, the data dimensions related to the above products are merely examples, and are not limited to uploading and displaying of the data dimensions of other necessary products.
In addition, the third parameter value also represents a characteristic value of a reordering rule for reordering the digits and letters in the first information, and in order to improve confidentiality, the characteristic value and the time of forming the uniform resource locator of the address are subjected to encryption calculation to obtain the third parameter value. The method can not determine the production time through the reverse ordering of the re-ordering rule under the condition that the re-ordering rule is not obtained, and the step which is introduced in the comparison process of the time period threshold value and is in the production time is combined, so that the situation that a consumer or a supervisor obtains tampered information in the process of obtaining product information through code scanning is effectively avoided. The characteristic value of the reordering rule is that the cross association between the uniform resource locator of the address and the two-dimensional code is established, the reordering rule can be changed periodically along with time, and the production time, the address time, the two-dimensional code generation time and the like of a product can be further checked by combining the selection of the reordering rule on a time node and the characteristic value of the corresponding time.
S104, if the time interval between the first time information contained in the first parameter value and the second time information contained in the third parameter value is smaller than a first threshold value, and the time interval between the third time information for generating the two-dimensional code and the second time information contained in the third parameter value is smaller than a second threshold value, generating the two-dimensional code at the time corresponding to the third time information at least based on the uniform resource locator of the address, wherein the first information and the third parameter value are the same as each other; otherwise, stopping generating the two-dimensional code.
In some embodiments, the first time information, e.g., the production time, contained by the first parameter value is defined to be less than a first threshold value with the second time information, e.g., the time to generate the uniform resource locator of the address, contained by the third parameter value; and limiting the third time information for generating the two-dimensional code and the second time information contained in the third parameter value, namely, the time for generating the uniform resource locator of the address, to be smaller than a second threshold value, and excluding products which are not suitable for being sold towards the market for a certain period of time. The first time threshold and the second time threshold are selected according to the expiration period of the product.
According to the embodiment, the time sensitive characteristic of the short-period product is combined with the uniform resource locator of the address of the public product information and the two-dimensional code of the address of the associated product and the address of the public product information, and the time difference between the three is used as the judging basis for forming the two-dimensional code, so that the temporary product is stopped from flowing to the market from the source. In addition, the two-dimensional code generation method provided by the embodiment writes the time characteristics into the uniform resource locator and the two-dimensional code at the same time, and writes the uniform resource locator and the two-dimensional code which are established by re-ordering as the cross relation of the association into the two-dimensional code, thereby providing a security foundation for the subsequent information query based on the two-dimensional code.

It should be noted that, for convenience and brevity of description, specific working processes of the above-described apparatus and each module and unit may refer to corresponding processes in the foregoing two-dimensional code generating method embodiment, and will not be described herein again.
Fig. 3 is a flow chart of an information obtaining method based on a two-dimensional code according to an embodiment of the present invention.

the first parameter value is a number in first information representing a product characteristic, the second parameter value is a letter in the first information representing the product, and the third parameter value is a time for forming a uniform resource locator of an address.
It will be appreciated that the address also includes the necessary paths, anchors, etc. Wherein the first parameter value, the second parameter value, and the third parameter value form key value pairs in a query parameter of the uniform resource locator.
The address is used for displaying corresponding data of the product so as to be checked after a consumer or supervision scans the two-dimensional code and verifies the two-dimensional code. The corresponding data of the product comprises information of a production stage before the generated two-dimensional code is printed and information of a transportation and sales stage after the generated two-dimensional code is printed. The information in the production stage is directly updated to the address after the address corresponding to the uniform resource locator is generated, and the information in the transportation and sales stage is uploaded to a database in real time in each subsequent environment and updated to the address.
Illustratively, the information of the production stage before the generated two-dimensional code is printed, such as basic information, lot information, supervision spot check, sunshine factory, brand propaganda, and the like. Taking a certain yogurt product as an example, the basic information includes: product name, business name, shelf life, specified unit, commodity bar code, etc.; the batch information includes: business name, unified social credit code, inspection report, etc.; the supervision spot check comprises: current batch spot check report, other batch spot check report, etc.; the solar plant includes real-time video of the production line that produced the product; the brand promotion then includes a corresponding graphic or food description of the business of the product.
Illustratively, the information of the transportation sales stage after the generated two-dimensional code is printed, such as transportation information, sales information, and the like. Typical shipping information includes: real-time transportation conditions such as transportation temperature, humidity and the like, and logistics information such as starting point position and time, end point position and time, passing transit position and time and the like. The sales information includes sales channels, time, and the like.
It should be noted that, the data related to the product includes time data of multiple stages, and the time data of the multiple stages is used as an auxiliary verification mode in the process of scanning the two-dimensional code for inquiring, so as to timely identify and avoid website tampering or other information vulnerabilities. Of course, the data dimensions related to the above products are merely examples, and are not limited to uploading and displaying of the data dimensions of other necessary products.
S302, after the second information is acquired at the first layer of the interface of the address and is verified to be consistent with the first information in the two-dimensional code, displaying the information of the second layer of the interface of the address.
When a first layer of the interface of the address does not obtain second information consistent with the first information in the two-dimensional code, the second layer is a fuzzy layer with unreadable information; when a first layer of an interface of the address obtains second information inconsistent with first information in the two-dimensional code, a third layer appears on the address, the second layer is kept as a fuzzy layer, and the third layer is used for prompting the first layer to obtain the second information inconsistent with the first information in the two-dimensional code and/or prompting to acquire the second information again.
In some exemplary embodiments, the first layer and the third layer are dialog boxes suspended over the second layer that are interactable by input. Continuing with the example of a yogurt product described above, batch information, such as 20230330M, is entered as indicated in a first layer containing an importable dialog box. Multiple verifications can be performed based on the entered batch information prior to jumping to the web site, with typical verification procedures as follows:
verification batch: verify 20230330M is 20230330M consistent with the content related to the product lot in the web site.
And (3) time verification: time information in the batch information is extracted, for example, 20230330 in this example. And verifying the uniform resource locator of the address and the time in the two-dimensional code. Specifically, extracting a characteristic value representing a reordering rule stored in the two-dimensional code in an encrypted manner, determining the ordering rule based on the characteristic value, and judging whether the time in a first parameter value obtained after analysis of the ordering rule is 20230330 or not.
The method can not determine the production time through the reverse ordering of the re-ordering rule under the condition that the re-ordering rule is not obtained, and the step which is introduced in the subsequent comparison process of the time period threshold and is in the production time is combined, so that the situation that a consumer or a supervisor obtains tampered information in the process of obtaining the product information by scanning the code is effectively avoided. The characteristic value of the reordering rule is that the cross association between the uniform resource locator of the address and the two-dimensional code is established, the reordering rule can be changed periodically along with time, and the production time, the address time, the two-dimensional code generation time and the like of a product can be further checked by combining the selection of the reordering rule on a time node and the characteristic value of the corresponding time.
In some embodiments, the verification means further comprises time-dependent verification. The second layer comprises a plurality of time information, and the time judgment is carried out before the second layer changes from the fuzzy layer to the display information: and if the time information falls into the association range with the first time information, the second time information and the third time information, displaying the information of the second layer, otherwise, keeping the second layer as a fuzzy layer and sending alarm information.
The plurality of time information are exemplified as: production time, packaging time, multiple node time during the logistics process, time in the inspection report, etc. According to the embodiment, through the attribute of the product with the shorter shelf life and time sensitivity, the possible error of the time relation in any link process is judged, and then the possible tampering or uploading error of part of data is timely identified. Therefore, the embodiment can effectively stop the falsified unreal data provided to the consumer or the supervision department and timely feed back the abnormal situation.
In some embodiments, the authentication means further comprises certificate authentication. The second layer comprises certificate information, and certificate judgment is carried out before the second layer changes from a fuzzy layer to display information: and if the certificate information passes verification, displaying the information of the second layer, otherwise, keeping the second layer as a fuzzy layer and sending alarm information.
According to the information acquisition method of the two-dimensional code, the relationship between the uniform resource locator and the address of the public product information and the two-dimensional code of the address of the associated product and the address of the public product information is established by combining the characteristic of the short-period product on time sensitivity, when verification based on the time information of the short-period product passes, the corresponding product information is disclosed, the disclosure and the provision of websites on tampered or wrong data are effectively avoided, and the tracing safety of the product and the credibility of data disclosure are improved.
