The embodiment of the invention provides a data processing method and a related device. The method comprises the steps of obtaining a configuration file corresponding to a target mobile application; the configuration file comprising a log, an SO library and a dex file, then according to the configuration file, obtaining loading information of the target mobile application running in the Android system, the loading information comprising application layer information, native layer information and interaction information between an application layer and a native layer, and then based on the record information, determining a stain leakage point and a stain propagation path of the target mobile application through a filter sieve. According to the stain propagation method, privacy data flow interaction between the application layer and the native layer is considered, and by adding the native layer data flow and the control flow, detection and monitoring of interaction of privacy data between the native layer and the application layer and between the native layer and the application layer are achieved when the mobile application runs in the Android system; and the problem of privacy data leakage related to the native layer is solved, and the security of the system is improved.
Description
technical field [0001] The present application relates to the technical field of data processing, and in particular to a data processing method and related devices. Background technique [0002] There are serious privacy leakage problems in the interaction process of mobile applications in the Android system. For example, malicious mobile applications obtain illegal benefits by stealing user privacy data such as text messages and bank card account passwords. Non-malicious mobile applications provide certain services such as map navigation. Privacy data such as location, etc. In recent years, developers tend to put the core functions of Android applications, such as encryption and T9 search functions, in the native layer to improve the execution efficiency of the application. Therefore, how to detect and monitor data flow in mobile applications that involve interaction with the native layer to prevent The issue of privacy data leakage has become a more important issue. Con...
