Technical Field

[0001] The present invention relates to the technical field of information sharing, and specifically to a digital information sharing method based on a heterogeneous platform. Background Art

[0002] In today's digital age, the effective sharing of digital information is crucial for the development of various fields. With the rapid development of information technology, a large number of heterogeneous platforms have emerged, and different operating systems, database management systems, application programs, etc. constitute a complex and diverse heterogeneous environment.

[0003] However, during the process of information storage and information sharing within a heterogeneous platform, there will be certain data security issues. How to achieve data security during information storage and information sharing within a heterogeneous platform is a problem that we need to solve. For this reason, a digital information sharing method based on a heterogeneous platform is provided herein. Summary of the Invention

[0004] The purpose of the present invention is to provide a digital information sharing method based on a heterogeneous platform.

[0005] The purpose of the present invention can be achieved through the following technical solutions: A digital information sharing method based on a heterogeneous platform includes:

[0006] Construct an access information link connected to the heterogeneous platform, and link the access information link with a user terminal that has obtained access permission;

[0007] Construct a database connected to each access information link, and import the digital information uploaded by the user terminal into the database for heterogeneous storage;

[0008] According to the information sharing request initiated by the user terminal, construct an information sharing space, and communicatively connect the constructed information sharing space with the corresponding database;

[0009] Through the information sharing space, protectively read the data information required for sharing in the database according to the information sharing request.

[0010] Further, the process of constructing an access information link connected to the heterogeneous platform and linking the access information link with a user terminal that has obtained access permission is as follows:

[0011] Set up an access application unit;

[0012] The user submits user basic information through the set access application unit, uploads the user basic information submitted by the user to the heterogeneous platform, and the heterogeneous platform reviews and approves the user basic information, and grants the user access permission;

[0013] Generate an access permission identifier corresponding to the user, and generate an account and password for entering the heterogeneous platform based on the access permission identifier;

[0014] Construct an access information link based on the generated access permission identifier, and link the heterogeneous platform with the user terminal through the constructed access information link;

[0015] Assign the access permission identifier to the corresponding user terminal through the access information link, send the account and password to the user, and back up the access permission identifier, account, and password in the heterogeneous platform.

[0016] Furthermore, the process of constructing a database connected to each access information link and importing the digital information uploaded by the user terminal into the database for heterogeneous storage is as follows:

[0017] Construct a corresponding database based on the user terminal that has obtained the access permission, and link the constructed database with the access information link connected to the user terminal;

[0018] The user logs in to the user terminal with the account and password held, and inputs the digital information to be uploaded into the user terminal;

[0019] The user terminal uploads the digital information input by the user to the database through the access information link;

[0020] Extract heterogeneous information from the digital information in the database to obtain corresponding heterogeneous features;

[0021] Construct corresponding data sub-libraries in the database according to the type features in the heterogeneous features, and set corresponding secure heterogeneous spaces in each data sub-library according to the security features;

[0022] First, classify the digital information according to the information type in the heterogeneous information to obtain a corresponding type information set, and import the type information set into the corresponding data sub-library;

[0023] Then, divide the digital information in each type information set according to information confidentiality to obtain corresponding confidential information and non-confidential information;

[0024] Import the confidential information into the secure heterogeneous space in the data sub-library;

[0025] Sort the digital information in each data sub-library and secure heterogeneous space according to the time feature;

[0026] Set corresponding access ports for each data sub-library and secure heterogeneous space;

[0027] Heterogeneously encrypt the confidentiality information in the secure heterogeneous space, generate the corresponding heterogeneous encryption key, and encrypt the access port of the secure heterogeneous space with the heterogeneous encryption key.

[0028] Further, the process of heterogeneously encrypting the confidentiality information in the secure heterogeneous space is specifically as follows:

[0029] Generate the corresponding time series according to the time when the confidentiality information is imported into the secure heterogeneous space;

[0030] Convert the imported confidentiality information and time series into the corresponding binary data streams;

[0031] Construct a header data block and set the data length of the header data block;

[0032] Perform a base conversion on the time series according to the data length of the header data block to obtain a base data stream consistent with the data length of the header data block;

[0033] Fill the obtained base data stream into the header data block;

[0034] Decompose the binary data stream corresponding to the confidentiality information into several data stream segments according to the data length of the header data block;

[0035] Perform a base conversion on each data stream segment according to the conversion base adopted by the time series to obtain the corresponding data segments;

[0036] Perform an exclusive OR operation on each data segment and the header data block bit by bit, and use the obtained exclusive OR operation result as the heterogeneous encryption key of the confidentiality information;

[0037] Encrypt the access port corresponding to the secure heterogeneous space with the heterogeneous encryption key and send the heterogeneous encryption key to the user side.

[0038] Further, when new confidentiality information is imported into the secure heterogeneous space, update the base data stream corresponding to the time series in the header data block, encrypt the newly imported confidentiality information with the updated base data stream to obtain a new heterogeneous encryption key, and iterate the original heterogeneous encryption key with the obtained new heterogeneous encryption key.

[0039] Further, according to the information sharing request initiated by the user side, the process of constructing an information sharing space and communicating the constructed information sharing space with the corresponding database is as follows:

[0040] The user initiates an information sharing request through the user side and enters the account of the shared target user;

[0041] According to the information sharing request initiated by the client, an information sharing space linked to the client is constructed within the heterogeneous platform;

[0042] According to the account of the shared target user input, a temporary sharing link corresponding to each shared target user is generated, and the information sharing space is linked to the database corresponding to the shared target user through the temporary sharing link.

[0043] Further, the process of the information sharing space protectively reading the data information required to be shared in the database according to the information sharing request is as follows:

[0044] According to the client linked to the information sharing space and the shared target user, a temporary information reading path linked to the access port in each database is constructed;

[0045] When the client or the shared target user needs to share the digital information in the database, the corresponding digital information is read through the corresponding access port through the temporary information reading path, and the read digital information is mapped to the client or the shared target user. After the corresponding user confirms the digital information to be shared, the corresponding digital information is imported into the information sharing space;

[0046] If the imported digital information is confidential information, the heterogeneous encryption key pair is used to perform permission encryption on the imported digital information;

[0047] If the imported digital information is not confidential information, other clients or shared target users linked to the information sharing space can directly operate on the imported digital information;

[0048] If the imported digital information is confidential information, several permission application items are generated for the imported confidential information, and each permission application item corresponds to a file operation permission;

[0049] Other clients or shared target users linked to the information sharing space apply for permissions from the user who imported the confidential information through the permission application items of the digital information. After the application is approved, the file operation permissions corresponding to the permission application items are obtained.

[0050] Compared with the prior art, the beneficial effects of the present invention are:

[0051] 1. According to the information confidentiality of the digital information uploaded by the user to the heterogeneous platform, the confidential information is classified and stored in the corresponding secure heterogeneous space, and according to the upload time of the latest confidential information, the heterogeneous encryption key used to encrypt the access port of the secure heterogeneous space is updated, so that each time the user's confidential information changes, the key can be updated, thereby improving the security of the confidential information;

[0052] 2. For the confidential information shared in the information sharing space, encrypt the shared confidential information with a heterogeneous encryption key pair, so that the security of the confidential information during the sharing process can be controlled by the user, and the leakage of the confidential information without the user's knowledge can be avoided.
