Embodiment 1

[0052] A business application file management system free of artificial modification, see figure 2 , the business application file management system is obtained by adding interception SDK to the original OA application;

[0053] The business application file management system adopts the method of intercepting the system file interface to automatically encrypt and decrypt the read and write operations of the business application file; adopts the method of intercepting the system response action to automatically encapsulate the original OA application program to realize the original OA application program. View preview of business application files.

[0054] The business application file management system free from artificial modification overcomes the problem of business application file leakage in the prior art, and greatly improves the SDK integration efficiency and the security of file reading through the modification-free program.

[0055] see image 3 , the business app...

Embodiment 2

[0081] A method of reading and writing based on the above-mentioned business application file management system, see Figure 4 , including the following steps:

[0082] After the business application file management system is started, add the SDK to intercept the initialization logic, and dynamically proxy the function;

[0083] Monitor the business application file management system to call the file IO read and write interface;

[0084] File stream encryption is performed on file IO write operations through the proxy interface class, and redirected to the sandbox file system;

[0085] The file IO read operation is redirected to the specified location of the sandbox file system through the proxy interface class and decrypted.

[0086] Specifically, the reading and writing method realizes interface function interception in the system through dynamic proxy technology, and performs file flow interception, encryption, decryption and redirection for operations involving file IO r...

Embodiment 3

[0089] A method for opening based on the above-mentioned business application file management system, see Figure 5 , 6 , including the following steps:

[0090] After the business application file management system is started, add the SDK to intercept the initialization logic, and dynamically proxy the function;

[0091] Monitor the business application file management system to call the system to open the file viewing interface action, and analyze to obtain the file type to be viewed;

[0092] Redirect to the interception SDK according to different file types through the proxy interface class to call different file reading components for parsing and display;

[0093] Check completion to monitor the closing action of the current page, close the display of the current file, and destroy the cached data.

[0094] Specifically, the opening implements the interface function interception through the dynamic proxy technology, and redirects the viewing response action of the busin...

Abstract

The invention provides a business application file management system free of manual transformation. The business application file management system is obtained by adding an interception SDK into an original OA application program; the business application file management system adopts a mode of intercepting a system file interface to automatically encrypt and decrypt read-write operation of a business application file, and automatically packages the original OA application program by adopting a mode of intercepting a system response action so as to realize viewing and previewing of the service application file in the original OA application program. According to the system, the problem of service application file leakage in the prior art is solved, and the SDK integration efficiency and the file reading safety are greatly improved through a transformation-free program.

Description

technical field [0001] The invention belongs to the technical field of network information security, and in particular relates to a business application file management system free from artificial modification, and a method for reading, writing and opening. Background technique [0002] The data encryption and decryption of business application files in existing original OA applications (such as Zhiyuan OA, collaborative office OA, etc.) requires development engineers to manually add encryption and decryption codes and carry out manual transformation before the encryption and decryption of business application files can be realized. Moreover, the existing original OA application itself does not have the file reading and preview function. To view business application files in the original OA application, a special file reading application (such as WPS) needs to be installed to view files. See figure 1 , which may have the risk of business application files being leaked. Con...
