Abstract
A method for verifying a user of a mobile device is provided. The method includes selecting a numerical value and generating a direction image based on the numerical value. The direction image may indicate a first position on the direction image and a second position on the mobile device when the direction image is initially displayed on the mobile device. The direction image may have a center point and the numerical value may correspond a central angle between the first position and the second position. The method may further include sending, to the mobile device, the direction image and a command to rotate the mobile device according to the direction image and receiving a magnetometric numerical value detected by the mobile device using a magnetometer. The method may further include determining whether to allow access of a server by the user based on the magnetometric numerical value.
