Embodiment Construction

[0028] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the implementation methods and accompanying drawings.

[0029] The present invention remakes the data storage structure of the Android mobile terminal, transforms the original system's single storage structure into multiple, and avoids changes to the core characteristics of the Android mobile terminal framework while ensuring user data environment isolation. Different from the traditional data structure with only one user data partition and the corresponding external storage area, the modified Android system framework takes over the original service in charge of user data mounting and removal. In the multi-user and data isolation technology In this case, the system will have an unlimited number of user data partitions, which are not visible to each other. Such as figure 1 As shown in the de...

Abstract

The invention discloses a data isolation method for an Android mobile terminal, which belongs to the technical field of Android system information security. The present invention remakes the data storage structure of the Android mobile terminal, transforms the original system's single storage structure into multiple, and avoids changes to the core characteristics of the Android mobile terminal framework while ensuring user data environment isolation. Different from the traditional data structure with only one user data partition and the corresponding external storage area, the modified Android system framework takes over the original service in charge of user data mounting and removal. In the multi-user and data isolation technology In this case, the system will have an unlimited number of user data partitions, which are not visible to each other.

Description

technical field [0001] The invention relates to the technical field of Android system information security, in particular to a data isolation method for an Android mobile terminal. Background technique [0002] The Android system has relatively complete functional interfaces and powerful network interconnection capabilities, and is currently the mainstream mobile terminal operating system. Compared with traditional mobile terminals, Android mobile terminals have higher performance processors, larger storage space, and stronger mobile network data transmission capabilities. While carrying out a large amount of business with the help of Android mobile terminals, more personal privacy data must be processed, so the issue of information security has become extremely urgent. The security mechanism of Android is mainly guaranteed by security technology. The existing security technology mainly includes traditional access control, permission-based security model, isolation and appl...
