Further, the file sharing unit 301 includes therein a temporary folder and a shared folder.
The temporary folder refers to a folder in which the information node temporarily stores files, wherein the files do not meet the requirement of sharing or belong to unfinished versions. The folder exists in the file sharing unit 301, but the folder and the file thereof are only visible, and if the information node wants to share the file in the folder, the information node sends the file to the shared folder.
The shared folder is a folder allowing permission sharing, and in the shared folder, the information node has all operation permissions of the files uploaded by the information nodes directly below the shared folder. The information node can share the operation authority of a certain file owned by the information node to other information nodes. It is emphasized that the information nodes have hierarchical properties, and can perform bidirectional rights sharing with directly connected information nodes, and the rights sharing with information nodes not directly connected needs to be confirmed or approved by related information nodes.
The access control unit 302 specifies the type of rights of the file and the operations that each right can perform, and also records the operation rights of the information nodes in each file.
Further, the authority type of the file comprises reading, uploading, downloading, modifying, renaming and deleting of the file.
The function of the rights handling unit 303 is that when one information node changes the rights of other information nodes to a file in the file sharing area, the rights handling unit 303 updates the rights of the corresponding information node to the file and pushes a message to the relevant information node.
Further, when the rights processing unit 303 receives a request for changing rights, it may determine whether the flow of the request conforms to the hierarchy, and then determine whether to change the rights.
The embodiment of the invention specifically illustrates a file sharing area schematic diagram of a file sharing method based on hierarchical nodes, and defines each component and function thereof in the file sharing area. The file sharing area stores files which are authorized to be operated by the information nodes in the file storage unit, and the information nodes do not need to find the files shared by different information nodes in different places, so that the file sharing method is convenient, quick and clear at a glance. The file sharing area opens the file to the information unit with the operation authority through the access authority unit, and meanwhile, the information node cannot contact the file without the operation authority, so that the safety of the information is ensured through the authority control. The information processing unit examines the permission change, so that the validity of file sharing is ensured, and information leakage caused by random file flow is limited to the maximum extent.

The information nodes in the hierarchical structure have hierarchical properties, can perform bidirectional interaction with the information nodes which are directly connected, and need to be confirmed or approved by related information nodes when interacting with the information nodes which are not directly connected. In particular, the hierarchy is a tree structure of connected information nodes according to an enterprise organization architecture.
The information node 401, the information node 402, the information node 403 and the information node 404 together form a simple tree-like hierarchical file sharing structure; in particular, the information node 401 and the information node 402 form a tree-like association, and the information node 402, the information node 403 and the information node 404 form a tree-like association; further, the information node 401 is a parent node of the information node 402, the information node 402 is a child node of the information node 401, the information node 402 is a parent node of the information node 403 and the information node 404, and the information node 403 and the information node 404 are child nodes of the information node 402; a transmission channel 405 exists between the information node 401 and the information node 402, a transmission channel 406 exists between the information node 402 and the information node 403, and a transmission channel 407 exists between the information node 402 and the information node 404.
Further, the hierarchical structure is formed by connecting information nodes according to an enterprise organization architecture, wherein the information nodes are abstract mapping models of enterprise staff in computers and correspond to the enterprise staff one by one.
Further, the transmission channel refers to a channel for transmitting rights change information of a file between information nodes.
Taking fig. 4 as an example, the information node 403 has a reading authority for a document, and the application shares the reading authority to the information node 404. Since the information node 403 and the information node 404 are not directly related information nodes, the information node 403 must first propose a sharing application to the information node 402 according to the limitation of the hierarchical structure, and after the information node 402 receives the push message and checks, the information node 404 receives the push message and has the reading authority for the file.
The embodiment of the invention specifically illustrates the hierarchical structure of a node type file sharing system, mainly comprises information nodes and transmission channels, and is used for connecting the information nodes into a tree node architecture so as to ensure the specification and safety of enterprise file sharing; in addition, the information nodes in the tree node architecture are in one-to-one correspondence with enterprise staff, so that the enterprise cooperation efficiency and the production efficiency are improved.
Fig. 5 is a schematic diagram of a configuration module of a file sharing system based on hierarchical nodes according to an embodiment of the present invention, which includes a data structure configuration unit 501, a node hierarchy configuration unit 502, and an access authority configuration unit 503.
The data structure configuration unit 501 is configured to configure information of staff in the real enterprise mapped by the information node, including data such as name, job number, identity, work skill, and history operation performed on the file.
The node level configuration unit 502 configures the relationship between the parent node and the child node of the information node according to the node association table.
The access right configuration unit 503 is configured to configure file operation rights for the information node.
Further, the configuration module can update the node association table of the information node by using the node hierarchy configuration unit 502, and reestablish the transmission channel. For example, an information node needs to add a lower information node, the configuration module needs to modify child node information of a node association table in the information node by using the node level configuration unit 502, and meanwhile, needs to modify parent node information in a node association table in the lower information node by using the node level configuration unit 502.
The configuration module schematic diagram of the file sharing system based on the hierarchical nodes provides node configuration, data configuration and authority configuration for the system, enhances the flexibility of file sharing, and improves the cooperation efficiency and production efficiency of enterprises.
The foregoing is merely illustrative of the present invention, and the present invention is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present invention should be included in the present invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
