Embodiment, belongs to the scope of disclosure protection.
A kind of as shown in Figure 1, flow signal of the detection method of gps coordinate cheating provided for one embodiment of the disclosure
Figure, this method comprises the following steps：
S1：Obtain global position system GPS coordinate information of the terminal in preset time period；
Specifically, the GPS coordinate information includes：Longitude, latitude and timestamp information.Wherein, the terminal is offer
Service side, such as the driver in vehicles dial-a-cab, used mobile terminal or personal computer for order
Equipment such as (Personal Computer, abbreviation PC).Such as smart mobile phone, personal digital assistant (PDA), tablet computer, notes
This computer, vehicle-mounted computer (carputer), handheld device, intelligent glasses, intelligent watch, wearable device, virtual display are set
Standby or display enhancing equipment (such as Google Glass, Oculus Rift, Hololens, Gear VR).
S2：The terminal obtained using base station location technology or WiFi location technologies is obtained in the preset time period
The first coordinate information；
Specifically, first coordinate information includes：Longitude, latitude and timestamp information.Base station location is generally used for
Mobile terminal, base station location service, which is called, does mobile location-based service (Location Based Service, abbreviation LBS), specifically
It is the positional information (latitude and longitude coordinates) that mobile terminal user is obtained by the network (such as GSM nets) of telecommunications mobile operator；
WiFi positioning is primarily referred to as：Mobile terminal has connected some Wi-Fi hotspot, then can call mobile whole in hotspot database
The geographical location information of all hot spots near end, so that signal strength and geographical location according further to neighbouring each hot spot
Information calculates the geographical location of mobile terminal.Then the of terminal can be obtained according to base station location technology or WiFi location technologies

The gps coordinate of terminal and at 2 the gps coordinate of terminal difference.The changing value of the signal strength of base station in preset time period
As：The difference of the signal strength of base station and the signal strength of same base station at 2 at 1.
S53：If the changing value of the gps coordinate is more than the second predetermined threshold value, the base station number does not change and described
The changing value of the signal strength of base station is less than the 3rd predetermined threshold value, then judges that the GPS coordinate information in the predetermined amount of time is
The coordinate information of forgery.
Specifically, when in preset time period terminal gps coordinate occur significant change, but terminal nearby base station number
Constant and base station signal strength does not have significant change yet, then shows that gps coordinate is the coordinate information of forgery in preset time period.
S54：If the changing value of the gps coordinate is less than or equal to the second predetermined threshold value, and the base station number changes
Or the changing value of the signal strength of the base station is more than or equal to the 3rd predetermined threshold value, then judges the GPS in the predetermined amount of time
Coordinate information is the coordinate information forged.
Specifically, when the gps coordinate of terminal in preset time period does not have a significant change, but the neighbouring base station number of terminal
Significant change occurs for change or base station signal strength, then shows that gps coordinate is the coordinate information of forgery in preset time period.
In the present embodiment, before step S5, this method further includes following steps：
Obtain the current address information of the terminal；Determine to work as with the terminal according to the terminal current address of acquisition
The distance of preceding address is less than the base station of pre-determined distance.
