Access control method and access control device of user data

Abstract

The invention discloses an access control method and an access control device of user data. The method comprises the following steps of: providing applications for users by means of application share according to the permission of the user accessing to a shared virtual machine and the permission corresponding to the application, wherein the shared virtual machine uniformly accepts the access of the users; and running the applications provided for each user, and realizing the access of each user to respective data. Furthermore, if the shared virtual machine does not have the appointed application, the user can perform custom installation and running. According to the method and the device, the users can access the user data in the virtual machine, and can define the needed application program, so that the user has large freedom degree, and through authentication on the user, the safety of the user data can be guaranteed. Because the software sharing in the virtual machine can avoid multiple installation of the software, the system resources can be effectively used, and the management cost of the virtual machine is reduced.

Description

technical field [0001] The present invention relates to the computer field, and in particular, relates to a user data access control method and device. Background technique [0002] In the public cloud computing environment, users customize resources and services according to their own needs. Due to the different needs of each user, it is not easy to make each user feel as convenient as they are on a PC when customizing resources and services, but virtualization technology can meet such requirements. virtualization technology, such as figure 1 As shown, a virtual machine is established for each user, and the user can install software on the virtual machine according to his own needs and perform personalized settings. [0003] In a private cloud environment, users have similar requirements and even need the same working environment, for example, a team collaborates on a task in a virtual machine. Such as figure 2 As shown, in this case, multiple users can use the shared ...

AI Technical Summary

Problems solved by technology

[0006] However, the existing systems based on shared virtual machines lack effective management measures for user applications, which leads to confusion in the process of users loading and running applications, which not only occupies system storage space, but also affects the rational use of system resources.

[0007] For the system problems caused by the lack of effective management of application loading and running in related technologies, no effective solution has been proposed so far
