Referring to fig. 1, fig. 1 schematically shows a flowchart of a data transmission method based on a block chain according to an embodiment of the present invention, where the data transmission method may be implemented by a server or a terminal device.
As shown in fig. 1, the data transmission method according to the first embodiment of the present invention includes the following steps S101, S102, and S103, which are described in detail below:
in step S101, a first interface file is acquired from the file system according to the first data information in the block chain.
In this embodiment of the present invention, the first data information may include at least one of a sending mechanism code, a receiving mechanism code, a service serial number, a service state, an AES (advanced Encryption standard) key corresponding to the first data information, and an interface file address, where the AES key includes an Encryption key and a decryption key; the service state may be any one of a state to be fed back, a state to be assembled, a state to be returned, and the like, and the embodiment of the present invention is not limited; AES is an advanced encryption standard, which may also be referred to as Rijndael encryption method, and the encryption process is to convert plaintext (e.g., my is mingmen) sent by a sender into ciphertext (e.g., tnyrrx + SNjZwEK + ZXFEcDw ═) according to a key (e.g., 123) of the sender, and further send the ciphertext to a receiver, so that the receiver can convert the ciphertext into plaintext through the key (e.g., 123). In addition, the AES algorithm can also be understood as a symmetric encryption algorithm, which is reversible, and compared with the conventional irreversible digest algorithm for checking the consistency and integrity of information, the AES algorithm can ensure that private information is not leaked, and improve the security of data transmission.
In an embodiment of the present invention, the File System may be a distributed File System (IPFS); the IPFS may also be referred to as an interplanetary file system or a point-to-point hypermedia protocol, and the use of the IPFS can improve the speed, security and openness of the internet. In the embodiment of the present invention, the IPFS serves as a file system for storing files.
In the embodiment of the present invention, the first interface file may be an interface file generated by the management party and corresponding to a service (e.g., an annuity service).
As an optional implementation manner, in the data transmission method based on the block chain. Before the first interface file is acquired from the file system according to the first data information in the blockchain, the method may further include the following steps: reading first data information from a block chain; and decrypting the target information in the first data information.
Further, the decryption method of the target information in the first data information may specifically be: determining a private key corresponding to a local node; and decrypting the target information in the first data information by using the private key.
In the embodiment of the invention, a manager can read first data information from the local blockchain node through a server/terminal device; the first data information may further include at least one of sender information, receiver information, intermediate data (i.e., matadata), and sending time.
In this embodiment of the present invention, if the first data information includes a sending mechanism code, a receiving mechanism code, a service serial number, a service status, an AES key, and an interface file address, the target information may include at least one of the service serial number, the service status, the AES key, and the interface file address. Since the target information is important information in the first data information, before the first data information is uploaded by the manager a (e.g., the hosting party), the target information in the first data information is encrypted by the public key of the manager B (e.g., the billing party), for example, the target information is encrypted by the RSA algorithm; the RSA algorithm is an asymmetric encryption algorithm, a pair of RSA secret keys can be generated through the RSA algorithm, and a private key stored by a manager and a public key which can be disclosed to the outside are included; further, the administrator B may decrypt the target information through the private key corresponding to the public key (i.e., the private key corresponding to the local node), and finally obtain the unencrypted information and the decrypted target information in the first data information, i.e., the complete first data information.
Therefore, by implementing the optional implementation manner, important information (e.g., an AES key) in the first data information can be encrypted by the public key of the receiving party (i.e., the above-mentioned administrator B), so that the receiving party decrypts the first data information by the private key corresponding to the public key, which not only can realize confidentiality of the important information, but also can synchronize data to other blockchain nodes in time by using a blockchain technology, thereby improving the transaction efficiency of a service (e.g., an annuity service).
As an optional implementation manner, in the data transmission method based on the blockchain, the target information includes a file address corresponding to the first interface file. The obtaining of the first interface file from the file system according to the first data information in the block chain may specifically include the following steps: determining a file address corresponding to the first interface file from the decrypted first data information; and acquiring the first interface file from the file system according to the file address corresponding to the first interface file.
In the embodiment of the present invention, according to the foregoing embodiment, the decrypted first data information may also be understood as decrypted target information, and a file address in the target information is used to indicate a storage location of the first interface file in the file system. After the management party acquires the file address through the server/terminal device, the management party can request the file system through the file address to obtain the first interface file corresponding to the file address.
Therefore, by implementing the optional implementation manner, the file address included in the target information can be obtained by decrypting the first data information, and then the first interface file is obtained by the file address request, so that the operation related to the current service is executed according to the first interface file.
In step S102, a second interface file is generated according to the first interface file and uploaded to the file system.
In the embodiment of the invention, after the manager obtains the first interface file through the server/terminal device, the manager can execute the payment related operation according to the first interface file (such as payment notification) and generate the feedback file (such as payment completion notification) after the payment related operation is executed, namely the second interface file, and then upload the second interface file to the file system so that other managers can obtain the second interface file from the file system.
As an optional implementation manner, in the data transmission method based on the blockchain, generating the second interface file according to the first interface file may specifically include the following steps:
executing data processing operation on the first interface file; the data processing operation comprises at least one of data analysis, data verification and data feedback; and generating a second interface file according to the first interface file subjected to the data processing operation.
In the embodiment of the present invention, optionally, the manner of generating the second interface file according to the first interface file after the data processing operation may specifically be: and taking the first interface file subjected to the data processing operation as a second interface file.
Further, uploading the second interface file to the file system may include the steps of: encrypting the second interface file; and uploading the encrypted second interface file to a file system.
Still further, encrypting the second interface file may include the steps of: randomly generating key information; wherein, the key information comprises an encryption key; the second interface file is encrypted by the encryption key.
In the embodiment of the invention, the key information can be an AES key; the AES key comprises an encryption key and a decryption key.
Still further, performing the data processing operation on the first interface file may include the steps of: decrypting the first interface file according to the key information corresponding to the first interface file; and executing data processing operation on the decrypted first interface file.
Therefore, by implementing the embodiment of the invention, the security of data transmission can be improved by adopting the AES encryption method and the RSA encryption method.
As an optional implementation manner, in the data transmission method based on the blockchain, the key information further includes a decryption key, and after the encrypted second interface file is uploaded to the file system, the method may further include the following steps: acquiring a file address which is returned by the file system and corresponds to the second interface file; and generating second data information according to at least one of the file address, the decryption key and the second interface file.
In this embodiment of the present invention, the second data information may include at least one of a sending mechanism code, a receiving mechanism code, a service serial number, a service status, an AES key corresponding to the second data information, and an interface file address. In addition, the file address corresponding to the second interface file is used to indicate the storage location of the second interface file in the file system.
In step S103, second data information corresponding to the second interface file is uploaded to the block chain.
In this embodiment of the present invention, optionally, the manner of uploading the second data information corresponding to the second interface file to the block chain may specifically be: and uploading second data information corresponding to the second interface file to the current blockchain node (namely, the local blockchain node).
As an optional implementation manner, in the data transmission method based on the blockchain, uploading the second data information corresponding to the second interface file to the blockchain may include the following steps: encrypting the second data information; and uploading the encrypted second data information to the block chain.
Therefore, by implementing the optional implementation mode, the encrypted second data information can be uploaded to the block chain, so that the receiver can timely acquire the second data information at the block chain link point where the receiver is located, and the service handling efficiency is further improved.
It can be seen that, when the block chain-based data transmission method shown in fig. 1 is implemented, each manager only needs to interact with the block chain link point where each manager is located, and the data interfaces of each manager are unified, so that the operation efficiency is improved to a certain extent compared with the conventional mesh-type data transmission method; in addition, because the file system adopted by the invention is a distributed file system, the file data can not be lost by individual management parties to cause great loss, and each management party can acquire the latest and most complete file information after the file is uploaded to the file system, the problem of data backup is not required to be considered, and the operation cost is reduced; in addition, due to the application of the block chain technology, the data uploaded by each management party can be synchronized to other block chain nodes in time, so that other management parties can acquire the data in time, and the service handling efficiency is improved; in addition, the invention also improves the safety of data transmission by adopting an AES encryption method and an RSA encryption method.
Referring to fig. 2, fig. 2 schematically illustrates a flow chart of data transmission by a trustee and an account based on a blockchain according to an embodiment of the present invention. As shown in fig. 2, the data transmission by the trustee and the account based on the blockchain includes a data file sending phase and a data file responding phase.
Wherein, the data file sending stage comprises the following steps:

Step S205: and assembling the sending mechanism code, the receiving mechanism code, the encrypted service serial number, the encrypted service state, the encrypted AES key and the encrypted interface file address to obtain first data information.
In the embodiment of the present invention, when a manager a (e.g., a trusted party) accepts a service (e.g., annuity service) through a server/terminal device, the manager a generates a data interface file (i.e., a first interface file) by notifying a payment corresponding to the annuity service through the server/terminal device; furthermore, the manager a may randomly generate an AES key through the server/terminal device, encrypt the first interface file through an encryption key in the AES key, and upload the first interface file to a file block of the IPFS, so as to obtain a file address corresponding to the first interface file returned by the IPFS, where the file address is used to indicate a storage location of the first interface file in the IPFS, and the file address may be represented by a hash value; further, the manager a may encrypt the service serial number (i.e., serial number corresponding to the annuity service), the service status (i.e., status of the annuity service, such as the status of payment), the AES key, and the interface file address (i.e., file address corresponding to the first interface file) through the server/terminal device via the public key of the receiving mechanism (e.g., the manager B); furthermore, the manager a can assemble the sending mechanism code (i.e., the mechanism code of the manager a), the receiving mechanism code (e.g., the mechanism code of the manager B), the encrypted service serial number, the service state, the AES key, and the interface file address into the first data information through the server/terminal device, and upload the blockchain through the current node (i.e., the node where the manager a is located); the assembling into the first data information may also be understood as packaging a sending mechanism code, a receiving mechanism code, a service serial number, a service state, an AES key, and an interface file address to obtain a file packet, that is, the first data information.
The data file response phase comprises the following steps:

Step S207: and decrypting the service serial number, the service state, the AES encryption key and the interface file address in the first data information.
Step S208: and acquiring the decrypted service serial number, the service state, the AES encryption key and the interface file address.

Step S213: and assembling the sending mechanism code, the receiving mechanism code, the encrypted service serial number, the encrypted service state, the encrypted new AES key and the encrypted interface file address to obtain second data information.
In the embodiment of the present invention, a management party B (e.g., an account management party) may periodically obtain first data information (e.g., once every two hours) from a block link point where the management party B is located through a server/terminal device, and obtain a first interface file from a file system according to the first data information in a block chain; furthermore, the manager B can decrypt the encrypted service serial number, the encrypted service state, the encrypted AES key and the encrypted interface file address in the first data information through the server/terminal equipment through the private key of the manager B; furthermore, the management party B can request data downloading from the IPFS through the decrypted interface file address through the server/terminal equipment so as to download the first interface file from the file block of the IPFS; further, the first interface file is decrypted by using a decryption key in the AES key, data in the first interface file is read and checked, a feedback file (i.e., a second interface file) corresponding to the first interface file is generated, a new AES key is randomly generated, the second interface file is encrypted by using an encryption key in the new AES key, and the second interface file is uploaded to a file block of the IPFS, so as to obtain a file address corresponding to the second interface file returned by the IPFS, wherein the file address is used for indicating a storage location of the second interface file in the IPFS and can be represented by a hash value; further, the manager B may encrypt the service serial number (i.e., serial number corresponding to the annuity service), the service status (i.e., status of the annuity service, such as paid-up completion status), the new AES key, and the interface file address (i.e., file address corresponding to the second interface file) through the server/terminal device through the public key of the receiving mechanism (e.g., manager C); further, the manager B may assemble the sending organization code (i.e., the organization code of the manager B), the receiving organization code (e.g., the organization code of the manager C), and the encrypted service serial number, the service status, the new AES key, and the interface file address into the second data information through the terminal device/server and upload the blockchain through the node where the manager B is currently located (i.e., the node where the manager B is located).
It can be seen that, by implementing the data transmission flow shown in fig. 2, each management party only needs to interact with the block link point where each management party is located, and the data interfaces of each management party are unified, so that the operation efficiency is improved to a certain extent compared with the conventional mesh-type data transmission mode; in addition, because the file system adopted by the invention is a distributed file system, the file data can not be lost by individual management parties to cause great loss, and each management party can acquire the latest and most complete file information after the file is uploaded to the file system, the problem of data backup is not required to be considered, and the operation cost is reduced; in addition, due to the application of the block chain technology, the data uploaded by each management party can be synchronized to other block chain nodes in time, so that other management parties can acquire the data in time, and the service handling efficiency is improved; in addition, the invention also improves the safety of data transmission by adopting an AES encryption method and an RSA encryption method.

Specifically, each node can handle the annuity service generated by the local annuity system module by using the mechanism front-end service module, and can transmit data related to the annuity service to the block chain service module in an encrypted manner, namely, encrypt and upload a block chain, so that the data related to the annuity service can be broadcast to other nodes and uploaded to an annuity block chain platform in time, and the block accounting module is triggered to record the data related to the annuity service; wherein, each node can also inquire the data related to the annuity service on the block chain through the network connection node module.
