Embodiment 1
[0022] see figure 1 , which is a schematicflowchart of a method for tracking cybercriminal targets using WI-FI and video surveillance equipment. Usually, for cybercrime, the IP address and network time of the target can be found through the website it attacks or eavesdrops on, etc. The tracking method includes the following steps:
[0023] In step S101, through the IP address of the target and the networking time, determine the hotspot AP whose IP address is connected through WI-FI within the networking time, and calculate the location information of the target according to the position of the hotspot AP;
[0024] In this embodiment, hotspot APs include hotspot APs provided in public places, such as airports, railway stations, passenger stations, and other transportation hubs, as well as hotspot APs provided by businesses, such as coffee shops, fast food restaurants, hotels, and shopping malls. and other service places, including more private hotspot APs.

Embodiment 2
[0034] The method of using WI-FI and video surveillance equipment to track the target of the stolen communication equipment. Usually, for the thief, the MAC address can be found through the purchased certificate. The tracking method specifically includes:
[0035] In step S201, through the MAC address of the target, determine the hotspot AP and networking time for WI-FI connection with the target, and calculate the location information of the target according to the location of the hotspot AP;
[0036] In this embodiment, hotspot APs include hotspot APs provided in public places, such as airports, railway stations, passenger stations, and other transportation hubs, as well as hotspot APs provided by businesses, such as coffee shops, fast food restaurants, hotels, and shopping malls. and other service places, including more private hotspot APs.
[0037] Among them, when searching, a hotspot AP with a fixed location, such as a public place or a business, is preferred, followed b...

Abstract
The invention provides a method for tracking a target through WI-FI and a video monitoring device. The method is based on a video spatial database and includes the following steps that firstly, a hotspot AP connected with an IP address through the WI-FI within networking time is determined through the IP address of the target and the networking time, and positional information of the target is calculated according to the position of the hotspot AP; secondly, according to the positional information of the target and the networking time corresponding to the positional information, the video spatial database is searched for coherent video data of the target or a target possessor; thirdly, peripheralvideo monitoring is associated, the coherent video data are found, and the moving trajectory of the target or the target possessor is tracked. The invention further provides a known MAC address tracking method. According to the method for tracking the target and the known MAC address tracking method, a WI-FI network and the video monitoring device can be combined to track criminal suspects who execute cyber crimes or steal a mobile device.
Description
technical field [0001] The invention relates to the field of positioning and tracking, in particular to a method for tracking a target by using WI-FI and video surveillance equipment. Background technique [0002] As WI-FI positioning technology becomes more and more accurate, and video surveillance equipment is also spread in every corner of the city streets, there is a lack of effective interaction mechanism between the two, especially in the field of positioning and tracking of moving targets. [0003] The recently emerging space-based video database technology is established through the geographic coordinates of urban video surveillance data. Such as Chinese patent application CN201310105427.3, the application date is March 28, 2013, and the name is a multi-video correlation monitoring and positioning device and method based on spatial information; another example is Chinese patent application 201310071391.1, the application date is March 6, 2013 , titled A Spatial Loca...
