For convenience of understanding, the block chain based multi-warehouse data management method in the embodiment of the present invention will be further described, please refer to fig. 2, and another embodiment of a block chain based multi-warehouse data management method in the embodiment of the present invention may include:
201. when the local inventory data of the warehouse nodes in the access block chain changes, the corresponding warehouse nodes update the local inventory data.
In the embodiment of the invention, management equipment can be configured for a plurality of storehouses in the same region or different regions, a point-to-point distributed data transmission and storage architecture is established through a block chain technology, the management equipment of each storehouse can be registered as a node of a block chain, each storehouse management equipment accessed into the block chain is used as a node of the block chain, and each node can independently upload and account data. When the local inventory data of the warehouse nodes in the access block chain changes, the corresponding warehouse nodes can update the local inventory data according to the operation of an administrator.
Optionally, as a possible implementation manner, in the embodiment of the present invention, a specific process of the repository node updating the local repository data may include:
receiving an updating request sent by a user through a client, wherein the updating request at least comprises a user ID;
and verifying whether the user ID is matched with a preset ID list, if so, receiving the operation information of the user, and updating the local inventory data according to the operation information.
The node device of each storehouse can be managed by one or more managers, can assign specific authority to each user, preset a corresponding ID list for each operation, and the user corresponding to the user ID in the ID list has corresponding operation authority. For example, each manager only has the management right of the warehouse data of one or more types of materials according to the different types of the materials of each warehouse, and the specific right distribution can be configured reasonably according to the actual needs, which is not limited herein.
After the authorities of different managers are configured, when the stock of actual materials in a warehouse changes, the corresponding manager can log in the node device according to the user ID and send an updating request to the node device, the node device can receive the updating request sent by a user through a client, the updating request at least comprises the user ID, the node device can verify whether the user ID is matched with a preset ID list, if the user ID is matched with the preset ID list, the user has a corresponding operation right item, and the node device can receive the operation information of the user and update local inventory data according to the operation information.
202. And writing the updated local inventory data into the block and synchronizing the data into the block chain.
After the node updates the local inventory data, the updated local inventory data may be written to the block for broadcasting, so that the node accessing the block chain synchronizes the latest block to the block chain and stores the latest block in the database of each node.
Further, optionally, as a possible implementation manner, in order to improve the data security, when each library node device sends out a broadcast message for block chain synchronization, a block in the broadcast message may be verified. Specifically, a corresponding ID and a corresponding key may be assigned to each repository node when the repository nodes are registered; the specific server can adopt a symmetric encryption algorithm to distribute keys and IDs for the storehouse nodes, or adopt an asymmetric algorithm to distribute a key pair and an ID for the storehouse nodes, if a symmetric encryption algorithm is adopted, in the symmetric encryption algorithm, a data sender can process a plaintext (original data) and an encryption key together through a special encryption algorithm, and then the plaintext and the encryption key are changed into a complex encrypted ciphertext to be sent out. After receiving the ciphertext, if the recipient wants to decode the original text, the recipient needs to decrypt the ciphertext using the Key used for encryption and the inverse algorithm of the same algorithm to recover the ciphertext into the readable plaintext, which is described in this embodiment by taking a Key pair distributed by an asymmetric algorithm as an example, where the Key pair includes a Public Key (Public Key) and a corresponding Private Key (Private Key), where the Public Key and the Private Key are obtained through an encryption algorithm, for example: the public key of the encryption Algorithm, namely the Levist-Samor-Adleman (RSA) or the Digital Signature Algorithm (DSA), is a public part of the key pair and is externally disclosed, and the private key is a non-public part and is not externally disclosed and needs to be stored by the storeroom node. The public key is typically used to encrypt session keys, verify digital signatures, or encrypt data that can be decrypted with a corresponding private key. The key pair derived by such an algorithm can be guaranteed to be unique worldwide. When using this key pair, if one of the keys is used to encrypt a piece of data, the other key must be used to decrypt the piece of data. For example, encrypting data with a public key necessitates decryption with the private key, and if encrypting with the private key, also must decrypt with the public key, otherwise decryption will not succeed. In the embodiment of the present invention, the length of the public key and the private key may be 256 bits (bit) or more in general. The public key can also be used for generating an identity ID, the ID can be generated by the public key through a certain operation, the ID and the public key correspond to each other one by one, and the ID can be the public key, a hash (hash) value of the public key, or a section of script containing the public key and an operation instruction, and the like. The ID is used to identify the storehouse node.
