Embodiment approach

[0041] According to an embodiment of the present invention, the step S112 includes: when the application data transfer system performs data transfer, it first checks whether the check codes provided by the applications A and B are consistent with the valid check codes stored by themselves. If they are consistent, perform data processing operations. Otherwise, no data transfer is performed, and the processing ends.

[0042] figure 2 Shows a flow chart of another embodiment of the data transfer method according to the present invention, the method of this embodiment includes figure 1 In addition to the steps of the shown method, after step S112, it also includes:

[0043] In step S202, the application data transfer system sets the unique check code as invalid after completing the data transfer operation. Alternatively, after the data transfer operation is completed by the application data transfer system, the unique check code may also be deleted.

[0044] In step S204, the...

Abstract

The present application discloses a data transfer method and device, wherein the method includes: in response to receiving a data request sent by a requesting application, checking whether the requesting application and the target application that will process the data request are credible; in response to the Both the requesting application and the target application are trusted, sending the data request to the target application; in response to the target application returning to allow a session, generating a unique check code and using it together with the requesting application information and the target application information Send to the application authorization center and the application data transfer system; the application authorization center adds the application data transfer system to the request application and the target application respectively according to the received request application information, target application information and unique verification code within the sandbox; the application data transfer system performs data transfer according to the unique check code it saves. The invention can solve the transfer of data between processes, and at the same time protect the security of application private data.

Description

technical field [0001] The present application relates to the field of electrical digital data processing, in particular to a data transmission method and device. Background technique [0002] Currently, the system provides a sandbox for each application in order to secure the application data, and stores the private data of the application in the exclusive sandbox to achieve the purpose of protecting application data security. In this way, data transfer between processes will be very difficult, but data interaction between applications is necessary in actual development. At present, a common way in the market is to provide a process (application with super authority) that can globally access each application sandbox to break through the private data of application data to solve the problem of data exchange between processes. However, once the super-authorized application is broken, the data of all applications in the entire system can be read, which greatly damages the sec...
