On one hand, the analysis server can establish the association information among the mobile phone number, the MAC address, the access time and the access place, and make the association information into a graph or a table for displaying, thereby being convenient for searching and identifying. Taking the table as an example, as long as any one of the mobile phone number, the MAC address, the access time, and the access location is used as a search term, the related data records can be found out, and the specific time and place where a certain MAC is collected by which station can be queried.
On the other hand, the analysis server may also perform a companion analysis. The accompanying analysis is that for a certain specified MAC, the MAC with the largest number of simultaneous occurrences is inquired according to the time period + station, for example, the mobile phone MAC of a known specified person, and meanwhile, the MAC which appears at the station A in the time period 1 and appears at the station B … … in the time period 2 and appears at the station X in the time period N is found through track inquiry, so that according to the MAC, which MACs and the MAC which appears at the stations simultaneously are inquired according to the inquiry conditions of all the time periods + station, and the occurrence number is close, the MAC with the higher number may explain the relationship with the specified person, and therefore, the MAC addresses with the largest number of simultaneous occurrences at the same place can be inquired, so as to provide the MAC with the data support for a spy person.
In still another aspect, the analysis server may perform collision analysis by counting MAC addresses detected at a specific location and a specific time period. The collision analysis means that when the specific MAC address and the mobile phone number of a designated person are not available and only the activity area is known, such as the station A, B … … X, the time period 1, and the time period 2 … … N, all data collected by the stations can be queried according to the conditions, and the MAC address with a higher or highest occurrence probability is matched, and the MAC address may be related to the designated person, so that the further investigation can be performed.
The MAC address information collection system in this embodiment can collect information such as a mobile phone number, an MAC address, access time, an access location, and the like, and can obtain a lot of useful data support through reasonable analysis of the information, for example, tracking of designated personnel, recording of internet access content of each WiFi terminal, and the like.
