Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

The embodiment of the application provides a multi-level supply chain based information sharing method. The execution subject of the multi-level supply chain information sharing method includes, but is not limited to, at least one of a server, a terminal, and the like, which can be configured to execute the method provided by the embodiment of the application. In other words, the multi-level supply chain based information sharing method may be performed by software or hardware installed at a terminal device or a server device. The service end includes but is not limited to: a single server, a server cluster, a cloud server or a cloud server cluster, and the like.

Example 1:

referring to fig. 1, a flow chart of a multi-level supply chain information sharing method according to an embodiment of the application is shown. In this embodiment, the multi-level supply chain based information sharing method includes:

S1, receiving an information sharing instruction of a multi-stage supply chain, wherein the multi-stage supply chain is composed of an agricultural product packing chain and an agricultural product storage chain, the agricultural product packing chain and the agricultural product storage chain are composed of a plurality of processing units, the agricultural product packing chain comprises an agricultural product collecting unit and a quality inspection packing unit, the agricultural product storage chain comprises a cold chain conveying unit, a discharging and checking unit and a warehousing storage unit, the number of the agricultural product packing chains is only 1, the number of the agricultural product storage chains is at least 2, and each agricultural product storage chain acquires agricultural products from a unique agricultural product packing chain.

It should be explained that the information sharing instruction is generally initiated by a manager of the multi-level supply chain. Illustratively, the sheetlet is a supply chain manager of an agricultural company currently planning to distribute 1000 mu of agricultural products from a planting point to a point of sale, in order to reasonably distribute the agricultural products to each point of sale, to improve the optimal distribution of the agricultural products at the planting point to each point of sale, and to prevent each point of sale from excessively high or excessively low storage of the agricultural products, so that the sheetlet initiates the information sharing instruction, and the main purpose of the sheetlet is to share processing information of each processing unit in real time when the processing of the agricultural products is performed, so that the agricultural products at the planting point are optimally scheduled.

It is emphasized that in embodiments of the present invention, the multi-level supply chain is comprised of a produce baling chain and a produce storage chain. And the agricultural product packing chain comprises an agricultural product collecting unit and a quality inspection packing unit, and the agricultural product storage chain comprises a cold chain conveying unit, a discharging and checking unit and a warehousing storage unit. For example, 1000 mu of agricultural products need to be delivered from a planting point to a point of sale, the quality of each agricultural product capable of being delivered needs to be confirmed, for example, 900KG of agricultural products are collected from the 1000 mu of planting point, 10KG which does not meet the sales condition is removed through quality inspection, and the remaining 890KG of agricultural products can be packaged, so that the agricultural product packaging chain can be formed by collection, quality inspection and packaging.

Further, after packaging is completed, the packaged 890KG agricultural products need to be distributed to different sales points, for example, the small sheets need to be distributed to A, B and C three sales points at this time, 3 sales points form 3 agricultural product storage chains, and each agricultural product storage chain consists of a cold chain conveying unit, a unloading checking unit and a warehousing storage unit.

It is important to note that, from the above description, there are only 1 agricultural product packing chain, and there are at least 2 agricultural product storage chains, that is, the agricultural products obtained by each agricultural product storage chain are all derived from the same agricultural product packing chain.

S2, accessing each processing unit of the multi-stage supply chain according to the information sharing instruction, and when the access is successful, acquiring processing data of the agricultural products processed by each processing unit, wherein the processing data consists of sensitive data and non-sensitive data, the non-sensitive data comprises structured data and monitoring video of the agricultural products, the sensitive data comprises residence time and quality loss of the agricultural products in the current processing unit, and characteristic data of the current processing unit, and the characteristic data comprises the number of staff, weather and throughput of the agricultural products processed per hour which can be dominated by the processing unit.

It should be explained that each processing unit has different processing tasks. For example, the processing task of the agricultural product collecting unit is to collect saleable agricultural products from a 1000 mu planting point, the processing task of the quality inspection packaging unit is to remove low-quality agricultural products collected by the agricultural product collecting unit, package the remaining agricultural products, and the like, and each processing unit generates corresponding processing data when processing the agricultural products.

In order to improve the intelligence of information sharing, the embodiment of the invention divides the processing data generated by the processing unit into sensitive data and non-sensitive data. The non-sensitive data comprises structural data of agricultural products and monitoring video. Further, the structured data of the agricultural product includes the kind of the agricultural product, the picking time when picking from the planting point, the planting time at the planting point, the seed model, the container model, the volume used by the processing unit when processing the agricultural product, and the like. Meanwhile, when each processing unit processes agricultural products, the system further comprises a monitoring video in order to improve processing standardization and safety.

Furthermore, the non-sensitive data can be shared by each processing unit at the same time, so that the main purpose of the non-sensitive data is to improve the breadth of information sharing, and therefore, each processing unit can conveniently achieve the purpose of information sharing, but the key point is that the sensitive data cannot be shared by each processing unit because the sensitive data relates to the actual condition of processing agricultural products by each processing unit, so as to improve the management capability of a multi-stage supply chain and strengthen the information security of the multi-stage supply chain.

The sensitive data includes residence time of the agricultural product in the current processing unit, quality loss, and characteristic data of the current processing unit, wherein the characteristic data includes the number of available employees of the processing unit, weather, and throughput of processed agricultural product per hour. For example, when the quality inspection packaging unit is used for processing tomatoes with total weight of 300KG, but the quality loss is 50KG when the tomatoes with the weight of 50KG are broken due to improper packaging operation, and in addition, the main reason for breaking the tomatoes is that the quality inspection packaging unit and the characteristic data of the processing unit do not meet the actual requirements, the number of staff can be controlled by the quality inspection packaging unit to be only 2, and the weather is storm.

And S3, summarizing and eliminating repeated structured data to obtain structured summarized data, after generating a tree-shaped hash value of the structured summarized data, sending the tree-shaped hash value to each processing unit, simultaneously storing the structured summarized data into a first database, and setting the tree-shaped hash value as an access password for accessing the structured summarized data.

It can be understood that the structured data collected by each processing unit may have the same data and different data, so in order to prevent the waste of storage resources, the embodiment of the invention needs to reject repeated structured data. Illustratively, the above-mentioned structured data of the agricultural product collecting unit includes the kind of agricultural product, picking time when picking from the planting point, etc., and the quality inspection packing unit includes the kind of agricultural product, picking time, and also includes the container model number, volume used for packing the agricultural product, so that the structured summarized data is obtained after eliminating the repeated data of the kind of agricultural product, picking time, etc.

Further, the generating a tree hash value of the structured summary data includes:

It should be explained that the hash algorithm is a function that can take as input data of arbitrary length and then map it to a string of fixed length. For example, the corresponding hash value may be generated according to the structured data of the cold chain transport unit, that is, the structured hash value of the cold chain transport unit.

In detail, the acquiring the supply number of each processing unit in the multi-stage supply chain includes:

sequentially numbering an agricultural product packing chain or an agricultural product storage chain to obtain a chain number, wherein the numbering mode is as follows: the packing chain of the agricultural products is numbered 1, the 1 st agricultural product storage chain is numbered 2, the 2 nd agricultural product storage chain is numbered 3, …nThe number of the agricultural product storage chain isn+1Wherein, the method comprises the steps of, wherein,nindicating the number of agricultural product storage chains;

In addition, each processing unit has a unique supply number in the multi-stage supply chain, and if the unloading checking unit belongs to the agricultural product storage chain of the multi-stage supply chain, the supply number may be: KT927-3-2, wherein KT927 represents a multi-stage supply chain, 3 represents a 2 nd agricultural product packing chain in the multi-stage supply chain, 2 represents that in the 2 nd agricultural product packing chain, the unloading inspection unit belongs to the 2 nd step according to the operation flow, namely the operation sequence number is 2, and the like, and the supply number of the quality inspection packing unit can be: KT927-1-2, the intermediate numeral 1 is denoted as the chain number of the agricultural product packing chain. As can be seen from the above description, in the embodiment of the present invention, the supply numbers KT927-3-2, KT927-1-2 and the structured hash values corresponding to the supply numbers are used as the input of the hash algorithm again, and the hash operation is performed again, so as to obtain the hash value of the supply number.

In detail, the arranging the supply number hash value of each processing unit according to the tree structure to obtain a tree hash value includes:

It should be noted that, the identifiers of the root node identifier, the first non-leaf identifier, and the second non-leaf identifier may be a hash algorithm, an elliptic encryption algorithm, or a simple function mapping, which are not described herein.

In particular, when the structured data of each processing unit is shared, the embodiment of the invention adopts a tree coding mode, and compared with the traditional encryption mode under shared data, the tree hash value generated by tree coding has more outstanding advantages, and in the traditional method, if the data is shared, all the structured data are firstly packed uniformly, then the packed structured data are encrypted to obtain encrypted structured data and an access password, and each processing unit accesses the encrypted structured data through the access password. Although structured data sharing can be realized, a great amount of resource waste is caused, for example, the warehouse-in storage unit temporarily dispatches the foam boxes firstly because of insufficient number of containers for storing agricultural products, so that the structured data of the warehouse-in storage unit needs to be updated, and according to the traditional data sharing method, all structured data needs to be packed again, so that resource waste is caused. In contrast, if the tree structure arrangement is adopted, when the structured data of the warehousing storage unit needs to be updated, only the structured data changed by the warehousing storage unit needs to be updated in the structured summary data, the supply number hash value corresponding to the warehousing storage unit is updated at the same time, and the updated supply number hash value is used for replacing the supply number hash value in the original tree hash value, so that a new tree hash value is generated for continuously accessing the structured summary data.

S4, constructing a first storage space for storing monitoring videos in a first database, wherein the first storage space consists of a central storage space and associated storage spaces, the central storage space is used for storing the monitoring videos of the agricultural product packing chains, the associated storage spaces are used for storing the monitoring videos of the agricultural product storage chains, the number of the central storage spaces is only 1, and the number of the associated storage spaces is the same as that of the agricultural product storage chains.

It should be explained that, compared with the structured data, the data volume of the monitoring video is more huge, and because the update speed of the monitoring video is far higher than that of the structured data, the monitoring video needs to have an efficient storage structure while ensuring real-time sharing, so that each processing unit can access the required monitoring video in time.

In detail, the constructing a first storage space for storing the monitoring video in the first database includes:

It can be understood that, compared with the traditional storage space, the first storage space constructed by the embodiment of the invention has more complete structure, and fully utilizes the characteristic of the tree hash value to construct the storage space conforming to the multi-level supply chain structure, namely the first storage space.

The embodiment of the invention constructs the first storage space according to the structural characteristics of the attribute hash value, conceivably, the central storage space is directly used for storing the monitoring video of the agricultural product packing chain, and each storage unit of the central storage space is used for storing the monitoring video generated by the corresponding processing unit in a refined manner. Similarly, the number of associated storage spaces is the same as the number of agricultural product storage chains, and the associated storage spaces are used to store the monitoring video of the corresponding agricultural product storage chains in the same manner as the central storage space.

S5, according to whether the monitoring video belongs to a storage agricultural product packing chain or an agricultural product storage chain, correspondingly storing the monitoring video in a central storage space or an associated storage space, and setting a corresponding access password according to the tree hash value.

In detail, the storing the monitoring video to the central storage space or the associated storage space according to whether the monitoring video belongs to the storage agricultural product packing chain or the agricultural product storage chain comprises the following steps:

From the above, the monitoring video generated by the processing unit belonging to the agricultural product packing chain is directly stored in the storage unit in the central storage space, the storage unit and the processing unit have the same supply number, the monitoring video generated by the processing unit belonging to the agricultural product storage chain is directly stored in the storage unit in the associated storage space, and each storage unit directly does not affect each other to be independently stored, namely, the independence of the monitoring video during storage is ensured, and the integrity is formed based on the structure of the first storage space.

In detail, the setting the corresponding access password according to the tree hash value includes:

For example, when the quality inspection packaging unit needs to access the monitoring video, the qualification of accessing the first storage space is obtained through the received first access password, and then the quality inspection packaging unit stores the supply number hash value in itself, so that the corresponding monitoring video can be accessed by using the supply number hash value of itself.

In addition, when the processing units want to share the monitoring video with each other, an exchange operation of the hash value of the provisioning number needs to be performed, and in detail, the setting of the corresponding access password according to the tree-shaped hash value further includes:

The method and the device have the advantages that the monitoring video belongs to non-sensitive data, so that when the processing units want to mutually access the monitoring video, the supply number hash values are required to be exchanged, and according to the steps, the supply number hash values are known to have dynamic variability, so that if the supply number hash values of the quality inspection packaging unit are changed, the last exchange of the supply number hash values is judged to be invalid, and the exchange is required to be executed again.

For example, if the cold chain transport unit wants to access the surveillance video of the warehousing storage unit, the shared video command is initiated, and obviously, the shared video command includes a hash value of the supply number of the cold chain transport unit, if the warehousing storage unit feels that the confidentiality of the cold chain transport unit on the software level is poor, the shared video command can be refused to be received, after waiting for the warehousing storage unit to improve the confidentiality, the shared video command is received again, and the hash value of the supply number of the warehousing storage unit is automatically sent to the warehousing storage unit, so that the sharing of the surveillance video of the warehousing storage unit and the cold chain transport unit is realized.

And S6, storing the sensitive data into a second storage space, wherein the second storage space is managed by a pre-built sensitive data management system, and the sensitive data management system further comprises an authorized access node, a re-encryption node and a data correction node.

In detail, the storing the sensitive data in the second storage space includes:

It should be explained that, the hash algorithm is an irreversible encryption algorithm, and the sensitive hash value generated by the hash algorithm can be used to determine the integrity of the original sensitive data, so as to achieve the effect of data proofreading. In addition, the embodiment of the invention performs encryption on the sensitive data based on the re-encryption means, so as to generate a re-encrypted ciphertext, wherein the re-encryption means is a currently disclosed technology and is not described herein.

And S7, when the processing unit needs to access the sensitive data, judging the legitimacy of the processing unit by using the authorized access node, and when the legitimacy passes, acquiring the sensitive data by using the re-encryption node and the data checking node and sending the sensitive data to the processing unit to finish information sharing of the multi-stage supply chain.

It should be explained that in the embodiment of the present invention, there are many means for judging the validity of the processing unit, such as according to the IP address of the processing unit, the operation information of the operator logging in the processing unit, the history violation record of the processing unit, and so on. Further, after confirming that the processing unit has validity, the obtaining sensitive data by using the re-encryption node and the data checking node and sending the sensitive data to the processing unit includes:

It should be explained that, the hash algorithm adopted in the embodiment of the present invention has operation consistency, that is, after the same sensitive data is operated by the same hash function each time, the generated hash values are the same, so that the embodiment of the present invention can execute the above-mentioned judgment.
