Title: KERNEL-BASED DETECTION OF TARGET APPLICATION FUNCTIONALITY USING VIRTUAL ADDRESS MAPPING
Abstract:
Systems, methods, and computer programs are disclosed for detecting high-level functionality of an application executing on a computing device. One method comprises storing, in a secure memory on a computing device, a virtual address mapping table for an application. The virtual address mapping table comprises a plurality of virtual addresses in the application binary code mapped to corresponding target application functionalities. The application is registered with a high-level operating system (HLOS). During execution of the application binary code, the HLOS detects when one or more of the virtual addresses corresponding to the target application functionalities are executed based on the virtual address mapping table.
