Step 2: and performing user identity authentication according to the user information and user information prestored in a preset user information database, and sending the access directory information and the file information to a distributed file storage system for storage after the user identity authentication is passed, so that the file distribution system acquires the file information from the distributed file storage system and distributes the file information to a corresponding service system according to the access directory information.
Optionally, the executing subject of the distributed file secure transmission method may be a dedicated server node newly added in the distributed file transmission system, for example, an identity authentication server.
Referring to fig. 1, it is understood that the distributed file transfer system including the authentication server 20 may generally further include: client 10, distributed file storage system 30, file distribution system 40, and business system 50.
The client 10 is connected to the authentication server 20, and the client 10 is configured to collect user information, access directory information, and file information input by a user, and send the user information, the access directory information, and the file information to the authentication server 20.
Alternatively, the authentication server 20 may implement the reception of user information, access directory information, and file information for user input based on Apache sshd (Java-written open source software that is open source for Apache foundation).
Optionally, the user information may include a user login name, a user login password, the access directory information is an address that the user wants to access in the distributed server cluster and/or a file directory that the user wants to access in the distributed file storage system 30, and the file information is a source file that the user wants to send to a target service system 50 in the distributed server cluster and/or wants to write to a target file directory in the distributed file storage system 30.

Optionally, the user information database 21 may also control, in real time, information such as authority and directory of the access user (for example, blacklist control) in a form of adding a foreground page, so as to achieve a higher level of monitoring requirement. In addition, distributed storage may be used instead of a database.
Optionally, the authentication server 20 performs user authentication, for example, matching between a user login name and a user login password, according to the received user information and user information pre-stored in the preset user information database 21, and sends the access directory information and the file information to the distributed file storage system 30 for storage after the user authentication is passed.
It can be understood that, by separately providing an authentication server 20 in the distributed architecture, the authentication operations of the unified entries of the different clients 10 are respectively implemented, and thus, the decoupling of the authentication operations of the clients 10 and the server operating system is also implemented (in the prior art, the user information is bound to the server operating system, and the decoupling is strong).
The file distribution system 40 is configured to obtain the file information from the distributed file storage system 30 and distribute the file information to the corresponding service system 50 according to the access directory information.
Optionally, the distributed file storage system 30 ensures that the same service can be obtained when the user accesses any server node in a file sharing manner, thereby completely solving the problem of coupling with the operating system in the conventional mode and realizing a distributed architecture of file services.
It can be understood that, since the authentication server 20 has completed the authentication operation on each client 10, the file information uploaded by the user through the client 10 may not need to perform the authentication operation separately on the corresponding service system 50, but the file distribution system 40 may distribute the file information to the corresponding service system 50 directly according to the access directory information, so as to perform the subsequent operation quickly and accurately.

In order to ensure that complete file information is obtained before performing file security verification on the file information, in an embodiment of the distributed file security transmission method of the present application, referring to fig. 4, the file security verification server 60 performs file security verification on the file information, and specifically includes the following steps:
step S101: the current file data size of the file information obtained from the distributed file storage system 30 is determined.
Step S102: and performing integrity verification according to the current file data volume and the verification file in the file information, if the integrity verification passes, judging that the file security verification passes, and otherwise, judging that the file security verification fails.
It can be understood that the file information may include a source file that a user wants to upload, a signature file for the source file, and a check file obtained based on the source file (for example, a check file including file data amounts of the source file and the signature file), where the check file may specifically be a json file in a ". check" format, which records file data amounts of the source file and the signature file, and after the file verification server 60 obtains the file information from the distributed file storage system 30, first calculate current file data amounts, for example, 10M, of the source file and the signature file in the file information, then perform numerical comparison with an actual file data amount included in the check file, and if the current file data amounts are equal, it indicates that complete file information has been obtained, that integrity verification is passed.
In order to accurately verify the integrity of the acquired file information, in an embodiment of the distributed file secure transmission method of the present application, the step S102 specifically further includes:
and judging whether the data volume of the current file is equal to the actual data volume of the file contained in the check file in the file information or not.
