Abstract: A technique detects mobile device emulation. The technique involves identifying, by processing circuitry, a user apparatus for mobile device emulation detection. The technique further involves collecting, by the processing circuitry, motion sensor data from the identified user apparatus (e.g., samples of accelerometer attributes, gyroscopic attributes, gravity attributes, etc. over multiple time periods). The technique further involves performing, by the processing circuitry, a motion sensor data analysis operation based on the collected motion sensor data. A result of the motion sensor data analysis operation indicates whether the identified user apparatus is a physical mobile device or an emulated mobile device.
