the user accesses the data storage module, inputs the logical name of the pesticide product data information to be accessed and the original owner identity information of the pesticide product, the data storage module triggers the transmission module to return a physical storage address of the file, then a control channel of the FTP Server where the data storage module and the file are located is established in the transmission module, and a control instruction is transmitted in the two channels and controls the FTP servers at the two ends to perform various operations.
4. A data query and sharing system as claimed in claim 1, wherein:
the data storage module is used for receiving and storing the original owner identity information of pesticide product and sending the original owner identity information of pesticide product sent by the plurality of data acquisition modules that the transmission module conveys, and send the original owner identity information of pesticide product and pesticide product to the block chain sharing module, specifically includes:
the pesticide product data information and the original pesticide product owner identity information sent by the data acquisition modules comprise, but are not limited to, pesticide product data information and original pesticide product owner identity information of manufacturers, processors, regulatory agencies, carriers, retailers and consumers of pesticide products;
the data storage module adopts a block chain storage mechanism, a data analysis interface is called to analyze the uploaded pesticide product data information and the original pesticide product owner identity information data according to the table field of the data storage module, then the data storage module is inquired according to the analyzed field, and if the current data exists in the data storage module, the original pesticide product data information and the original pesticide product owner identity information data are spliced with the data storage module to form new data and packaged into a transaction; if the data does not exist in the data storage module, the data is directly packaged into the transaction, the data storage module sends the transaction to the block chain and obtains the hash value of the transaction, a FP-Growth method is adopted to carry out association rule analysis on the data after the hash value of the transaction is obtained, and finally the hash value is written into a corresponding field of the data corresponding to the transaction of the data storage module and returned to the user.
5. A data query and sharing system as claimed in claim 1, wherein:
the key management distribution module is used for distributing a security key to data information of each part in the system, and specifically comprises:
the user inquiry end randomly generates a pair of asymmetric encryption keys: the user inquiry end acquires the public key B of the key management distribution module, encrypts user information and the public key A by using the public key B of the key management distribution module, and then distributes the user information and the public key A to the key management distribution module;
the key management distribution module encrypts the quality data and distributes the quality data to corresponding blocks of the main block chain, the encrypted quality data are distributed to the corresponding blocks of the main block chain, each node has a public key and a private key, the public key is published to all members in the block chain, and the private key is used as a key for verifying identity and information in a transaction process;
after the key management distribution module receives the data, the private key B of the key management distribution module is used for decrypting the data to obtain user information, user hardware information and a public key A;
the pesticide product data information and the pesticide product original owner identity information data in the data storage module are updated or inquired through calling of the keys, one key can call another key to access the state of the pesticide product data information and the pesticide product original owner identity information data under the permission of legal authority, and the calling is irrelevant to a channel where the key is located;
the key management distribution module verifies the user information, and if the user information is illegal, the key management distribution module distributes information to the user inquiry terminal to prompt the user; if the user information is legal, the key management and distribution module searches and confirms the user hardware information in the database;
the method comprises the following steps that a user compiles functions intended to be realized to form an application program and deploys the application program to a Fabric network, a secret key runs in a Docker container, and a mirror image is automatically generated when the secret key is deployed to the network;
and the key management distribution module encrypts a private key by using the mirror image and distributes the private key to the user inquiry end, and the user inquiry end decrypts the data by using the private key A after receiving the data to obtain a private key C, and distributes the private key C to each data source to be stored in the data storage module.
6. A data query and sharing system as claimed in claim 1, wherein:
the block chain sharing module is used for receiving the pesticide product data information and the original owner identity information of the pesticide product sent by the data storage module and sharing the pesticide product data information, and specifically comprises the following steps:
the pesticide product data information and the original owner identity information of the pesticide product are shared to form a data storage record in a file format;
designing the data storage record to generate a new data storage record in one hour for recording transmission records in one hour, and generating a new data storage record every other hour by taking the integral point of each hour as a starting point, wherein the new data storage record is named by the character string of the integral point of the hour when the new data storage record is generated;
recording a Merck tree root of the data storage record and a timestamp character string when the file is generated at the beginning of the file of the new data storage record, then starting to record user uploading information which is verified by a system within the hour after the new data storage record is generated, and recording data transmission messages which are verified one by one into the file according to a format designed by a recording text; and selecting file uploading sharing, adding description information to the file, verifying the received signed information, and updating the data passing the verification into the data storage record by the whole network, thereby realizing data sharing.
