Embodiment Construction

[0019] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0020] The invention proposes a concept of performing pre-safety detection on Android software. Due to the open source characteristics of Android, in the embodiments of the present invention, the ROM (Read-Only Memory, read-only memory) of the Android system emulator is deeply customized, and some functions related to system security are set in the Android system emulator Insertion (Stub), so as to culture and observe the virus. Wherein, the so-called stub insertion refers to inserting additional code into the program to obtain behavior information of the program during execution. In the embodiment of the present invention, the code for executing malicious code monitoring is inserted into the Android system emulator as an example for description. . As a specific example, it is determined whether the software to be detected contains malicious cod...
