With continued reference to FIG. 2, a flow 200 of one embodiment of a method for storing data in accordance with the present application is shown. The method for storing data comprises the following steps:
In the present embodiment, an electronic device (e.g., a destination server (data acquirer) shown in fig. 1) on which the method for storing data operates may acquire at least one piece of original information from a data source server (data provider) that provides the original information by a wired connection manner or a wireless connection manner. The electronic device may also be a server separate from the target server. Wherein each piece of original information in the at least one piece of original information comprises an item code and item information. The item code may be a bar code identification specified by the international association for item codes for codes representing retail goods, non-retail goods, logistics units, participant positions, and the like. The article information may be traceability data of the article, such as information of the production place and production date of the article. Different nodes belonging to the same regional chain may be deployed on the target server and on the data source server, respectively.

In some optional implementations of the present embodiment, the at least one piece of raw information is obtained from the data source server in an electronic data exchange. EDI (Electronic Data Interchange) is an international standard introduced by the international organization for standardization, and refers to a method for Electronic transmission from a computer to a computer, which forms a structured transaction or message format for business or administrative transactions according to a recognized standard, and is also a business language recognizable to the computer. For example, data such as purchase orders, packing lists, and bills of lading in international trade are exchanged. Data standard docking can be carried out according to an EPCIS (EPCIS is an EPCglobal network service, through which service business partners can exchange Internet of things product electronic code related data through a network) interface standard and an AS2 (availability status 2) protocol, data provided by a data provider is completely synchronized to an EDI data processing system of a data acquirer, newly added, modified and deleted data are pushed to the EDI data processing system of the data acquirer by the data provider in batches every day, and then the EDI data processing system analyzes an EPCIS message and pushes the EPCIS message to a tracing system.
In the present embodiment, the hash table is a table that maps a group of keywords onto a limited address interval according to a set hash function and a collision processing method, and takes the "image" of the keyword in the address interval as a storage location recorded in the table, such table is called a hash table or hash, and the resulting storage location is called a hash address or hash address. As a linear data structure, the hash table is undoubtedly a faster one than tables, queues, and the like.
And 203, encrypting the at least one hash code obtained by conversion according to a preset secret key to obtain at least one encrypted hash code.
In this embodiment, each hash code is encrypted to obtain an encrypted hash code. The key may be the blockchain account number of the data source server. The blockchain account number can be used for digital signature to ensure the integrity of information transmission, the identity authentication of a sender and prevent repudiation in transactions. The receiver can decrypt the encrypted digest information only by using the public key of the sender, and then generates a digest information for the received original text by using the hash function, and compares the digest information with the decrypted digest information. If the two information are the same, the received information is complete and is not modified in the transmission process, otherwise, the information is modified, and therefore the digital signature can verify the integrity of the information.
And 204, encrypting each item information in the at least one piece of original information according to the secret key to obtain at least one piece of encrypted item information.
In this embodiment, each piece of item information is encrypted to obtain encrypted item information. The key used for encrypting the article information is the same as the key used for encrypting the hash code.
In this embodiment, the blockchain includes a first node and a second node, the first node of the blockchain is a node of the blockchain deployed at the target server, and the second node of the blockchain is a node of the blockchain deployed at the data source server. After the at least one encrypted hash code and the at least one piece of encrypted article information are stored in the blockchain, the blockchain returns a main key identifier (for example, an article code) of the transaction, stores the main key identifier of the transaction and associates the main key identifier with original data, and records the corresponding relation between the at least one encrypted hash code and each piece of encrypted article information in the at least one piece of encrypted article information and the storage position of each piece of encrypted article information.
In some optional implementations of this embodiment, the method further includes: in response to receiving a query request which comprises a target article code and is sent by a terminal, converting the target article code into a target hash code according to a hash table; encrypting the target hash code according to the secret key to obtain an encrypted target hash code; determining the storage position of the encrypted article information corresponding to the target article code according to the encrypted target hash code; acquiring the information of the encrypted target object from the determined storage position and decrypting the information according to the key; and sending the decrypted target article information to the terminal. The target item code is an item code to be queried, such as an item barcode on the packaging of the item. When the terminal queries the article information corresponding to the article code, the terminal does not need to directly access the official website server, and only needs to query through the target server. When the terminal sends the query request, the scanned commodity bar code can be sent to the target server in a code scanning mode. And the target server performs hash processing and encryption processing on the commodity bar code to obtain a target encrypted hash code. According to the corresponding relation and the storage position between the encrypted hash code and the encrypted article information which are stored before, the encrypted target article information corresponding to the target encrypted hash code can be found. And decrypting the encrypted target object information and then sending the decrypted target object information to the terminal. And the terminal can display the article information corresponding to the target article code. For example, a user scans a bar code on a milk box by using a terminal, the bar code is sent to a target server, and the target server performs a series of conversion on the bar code and then finds the information of articles such as production date, milk source origin, milk cow variety and the like corresponding to the bar code.
In some optional implementations of this embodiment, the method further includes: synchronizing at least one encrypted hash code and at least one piece of encrypted article information stored in a first node of a block chain into a second node of the block chain, wherein the second node is located in a data source server; and sending the hash table and the key to the data source server so that the data source server can verify at least one piece of original information through the second node based on the hash table and the key. And the blockchain node synchronizes the blockchain data to other nodes of the alliance chain through a data synchronization function so as to endorse each other. In addition to synchronizing the data, the hash table and key are also disclosed so that the data source server can verify that the original data has been tampered with.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for storing data according to the present embodiment. In the application scenario of fig. 3, first, the blockchain trace back system 303 opens a trace back system account and a blockchain account for the data provider 301, and maps and binds the trace back system account and the blockchain account. Secondly, original data including article codes and article information of the data provider 301 are subjected to data transmission through an AS2 protocol, the original data are stored in a database of the block chain tracing system 303, then the block chain tracing system 303 performs hash processing on each piece of original data, then a block chain account (secret key) is used for signing the data, then the signed data are stored in a block chain link point (first node) of a data acquirer 304 in the block chain, the block chain returns a main key identifier of the transaction to the block chain tracing system 303, the block chain tracing system 303 stores and associates the original data, and a hash table and the block chain account are disclosed. And the block chain node synchronizes the block chain data to other nodes of the alliance chain through a data synchronization function.

This step corresponds to step 201, where the data source server sends at least one piece of original information to the target server, and the target server executes step 201 and step 205 after receiving the at least one piece of original information.
In this embodiment, the first node is located at the destination server, the second node is located at the data source server, the at least one encrypted hash code is obtained by converting an item code into a hash code by the destination server based on a preset hash table and encrypting the converted hash code according to a preset key, and the at least one piece of encrypted item information is obtained by encrypting the at least one piece of item information by the destination server. The target server stores the at least one encrypted hash code and the at least one encrypted item information to a first node of the regional chain deployed on the target server, via step 201 and 205. The data origin server then synchronizes the at least one cryptographic hash code and the at least one cryptographic commodity information stored in the first node to a second node of the blockchain deployed on the data origin server.
