Abstract

The present invention proposes a terminal peripheral control method and device based on Android local layer hooking. The method is that all processes load the security framework and peripheral control execution module through the modified linker; the peripheral control execution module implements specific peripheral control behaviors according to the peripheral control security policy, and submits security audit logs; in the device, the core The security service module is used to provide the security framework with loading configuration for terminal peripheral control in the background, and provides a security policy access interface in the form of a local slot for the peripheral control execution module; the peripheral control policy module is used for persistent storage of peripherals Control security policy; the peripheral control execution module is used to implement specific peripheral control behaviors according to the peripheral control security policy, and submit security audit logs. The invention can prevent privacy and sensitive information from being leaked due to uncontrolled use of terminal peripherals by malicious programs, and has the characteristics of high transplantation and adaptation efficiency and high self-security.

Description

technical field [0001] The invention belongs to the technical field of mobile intelligent terminal security management, and in particular relates to a terminal peripheral control method and device based on an Android local layer hook. Background technique [0002] Smart mobile terminals of the Android system usually include peripherals such as cameras, 3G / 4G radio frequency modules, recording modules, and positioning modules. The terminals use these peripherals through various applications such as cameras, telephones, information, tape recorders, and maps. In the Android system, the application program is mainly developed in the Java language, and uses various system services through the API provided by the Android system operating framework (Framework). At the same time, the application program can also embed the JNI library, directly access the local layer system service through the JNI library, or access the terminal peripherals by operating the device file. With the pop...
