Embodiment Construction
[0061] In related technologies, when determining whether a mobile device is a virtual mobile device simulated by an emulator, it is usually possible to use some unique processes running on the virtual device that are different from normal mobile devices according to the characteristics of the processes running on the virtual device. The process is added to the blacklist.
[0062] When it is necessary to determine whether the target mobile device is a virtual device, the process running on the target mobile device can be scanned to determine whether the process running on the target mobile device hits the above blacklist; if it hits the above blacklist, the target can be The mobile device is determined as a virtual device.
[0063] However, through the method of process blacklist, although it can be determined to some extent whether the target mobile device is a virtual device, the information in the blacklist will have a certain lag, and in some security protection scenarios w...

The invention provides a method and device for judging whether a mobile device is a virtual device or not. The method comprises the steps of collecting an APP list of each mobile device in a target device library and coding the APP list based on whether various appointed state changes occur in APPs within a preset time period or not; carrying out statistics on occurrence probabilities of various appointed state changes corresponding to the APPs in the APP list; calculating an APP state change probability of each mobile device in the target device library based on the occurrence probabilities; and when whether any target mobile device in the target device library is the virtual mobile device or not is judged, comparing the APP state change probability of the target mobile device with an average value of the APP state change probabilities of the mobile devices in a pre-marked normal mobile device library and the virtual mobile device library, thereby judging whether the target mobile device is the virtual mobile device or not. According to the method and the device, the accuracy of judging whether the mobile device is the virtual device or not can be improved.
Description
technical field [0001] The present application relates to the communication field, and in particular to a method and device for determining whether a mobile device is a virtual device. Background technique [0002] With the rapid development of the mobile Internet, the application of the Internet is becoming larger and larger, so security protection is becoming more and more important, especially in the field of e-commerce, where financial losses due to hacker fraud account for a large proportion. Malicious users simulate virtual mobile devices through simulators to bypass risk control rules, thereby achieving the purpose of selling stolen goods, defrauding marketing resources, and distributing spam, causing huge losses to the e-commerce industry. Therefore, how to more accurately identify the virtual mobile device simulated by the simulator will be of great significance for security protection work. Contents of the invention [0003] This application proposes a method fo...
