and the second positioning terminal acquires the first positioning signal in the server in real time, and shields the second positioning signal of the second positioning terminal or transmits at least one false positioning signal to the server.
7. The method of claim 6, wherein after the steps of the second positioning terminal acquiring the position of the first positioning signal in the server in real time and masking the second positioning signal of the second positioning terminal or transmitting at least one dummy positioning signal to the server, the method comprises:
and the second positioning terminal stores the position of the first positioning signal acquired in real time so as to reproduce the moving track of the first positioning terminal.
8. The method of position tracking according to claim 6, wherein the first positioning signal and the second positioning signal are both GPS signals.
9. An anti-tracking system, comprising:
the second positioning terminal is used for acquiring a first positioning signal of the first positioning terminal from the server;
the first positioning terminal is used for acquiring the following time length of a second positioning signal of the second positioning terminal in a preset distance range, and when the following time length is greater than a time length threshold value, a countertracking measure is taken, wherein the countertracking measure comprises at least one of shielding the first positioning signal and transmitting at least one false positioning signal to the server.
10. A system for location tracking, comprising:
the first positioning terminal is used for sending a first positioning signal to the server;
and the second positioning terminal is used for acquiring the first positioning signal in the server in real time, shielding the second positioning signal of the second positioning terminal or transmitting at least one false positioning signal to the server.
