Privacy disclosure monitoring method of android application file

Abstract

The invention discloses a privacy disclosure monitoring method of an android application file. The privacy disclosure monitoring method includes: 1, converting a Dalvik byte code file in the android application file to generate a Jimple-format file; 2, parsing the Jimple-format file to generate control flow of a program, and performing privacy disclosure detection in components; 3, detecting Intent in the android file, and performing privacy disclosure detection among the components; 4, embedding a strategy implementation code module together with privacy disclosure detection results into the application program; 5, installing and running embedded application, and dynamically monitoring the application. By the privacy disclosure monitoring method, accuracy of user's privacy disclosure detection is improved, security defense of a system is enhanced, and risk of user's privacy disclosure is reduced to certain extend; the privacy disclosure monitoring method can be used for detection and protection of the android application file.

Description

technical field [0001] The present invention relates to the field of computer technology, and further relates to a method for monitoring privacy leakage of Android application files in the field of mobile device security technology. The invention effectively controls and reduces the leakage of private information existing in the application program by performing static analysis, detection and dynamic interception on the application program on the Android platform. Background technique [0002] The Android system is currently the most popular mobile smart operating system. The security mechanism of the Android system runs through the Linux operating system kernel, runtime, application program framework and other architectures, and involves the realization of functional modules such as application program components, and strives to protect user information, mobile Device and wireless network security. The Android security model inherits the secure Linux kernel, isolates proce...

AI Technical Summary

Problems solved by technology

The disadvantage of this method is that the way to detect privacy leakage is too single, and it is only limited to the privacy leakage detection of log files.

The disadvantage of this method is that the type of privacy data detected is limited, and the method of sending detected data only involves the traditional and most commonly used methods

The disadvantage of this method is that it cannot detect implicit inter-component communication behavior
