Description

一种移动终端MAC数据采集方法Mobile terminal MAC data acquisition method 技术领域Technical field

本发明涉及一种数据采集方法，更具体的说，它涉及一种移动终端MAC数据采集方法。The invention relates to a data collection method, and more particularly to a mobile terminal MAC data acquisition method.

背景技术Background technique

2014年苹果曾在iOS 8发布的时候宣布了一个旨在保护用户隐私的新功能，即当iOS 8手机，会使用随机MAC地址，从而帮助保护用户隐私，防止基于WIFI MAC的用户追踪行为。In 2014, when Apple released iOS 8, it announced a new feature designed to protect user privacy. When iOS 8 phones, they use random MAC addresses to help protect user privacy and prevent WIFI MAC-based user tracking behavior.

目前使用的MAC地址收集方法，对于ios 8以上系统，WIFI处于未关联状态时，只能识别MAC地址是否是随机MAC地址，无法获取手机真实MAC地址。The currently used MAC address collection method, for the IOS 8 or higher system, when the WIFI is in an unassociated state, it can only identify whether the MAC address is a random MAC address, and cannot obtain the real MAC address of the mobile phone.

发明内容Summary of the invention

针对现有技术存在的不足，本发明的目的在于提供一种移动终端MAC数据采集方法。In view of the deficiencies of the prior art, an object of the present invention is to provide a method for collecting MAC data of a mobile terminal.

为实现上述目的，本发明提供了如下技术方案：一种移动终端MAC数据采集方法，其方法具体包括以下步骤：To achieve the above objective, the present invention provides the following technical solution: a mobile terminal MAC data collection method, and the method specifically includes the following steps:

第一步，定时地在2.4GHz和5.8GHZ的各个频道上抓取WIFI无线通信数据包；The first step is to periodically grab the WIFI wireless communication data packet on each channel of 2.4 GHz and 5.8 GHz;

第二步，解析各数据包的802.11协议帧头，从帧头的BSSID字段、Source address字段、Destination address字段中提取出MAC地址；In the second step, the 802.11 protocol frame header of each data packet is parsed, and the MAC address is extracted from the BSSID field, the Source address field, and the Destination address field of the frame header;

第三步，系统判定获取到的手机MAC是否为真实MAC地址， 若不是真实MAC地址，解析报文获取曾经关联过的SSID信息；In the third step, the system determines whether the obtained MAC address of the mobile phone is a real MAC address. If it is not a real MAC address, parse the message to obtain the SSID information that has been associated;

第四步，发送Beacon报文和probe response报文，报文携带缓存SSID或者常用SSID信息；The fourth step is to send a Beacon packet and a probe response packet, where the packet carries the cached SSID or the commonly used SSID information.

第五步，获取手机回应的报文解析真实WIFI MAC地址。The fifth step is to obtain the real WIFI MAC address of the message that the mobile phone responds to.

本发明具有下述优点：本发明安装在苹果手机ios 8以上或类似系统，WIFI处于未关联状态时，获取真实WIFI MAC地址，等于准确获取身份识别码。The invention has the following advantages: the invention is installed on the Apple mobile phone ios 8 or above or similar system, and when the WIFI is in an unassociated state, obtaining the real WIFI MAC address is equivalent to accurately obtaining the identification code.

具体实施方式detailed description

参照图1、图2所示，本实施例的一种移动终端MAC数据采集方法，其方法具体包括以下步骤：Referring to FIG. 1 and FIG. 2, a method for collecting data of a MAC address of a mobile terminal according to this embodiment includes the following steps:

第一步，定时地在2.4GHz和5.8GHZ的各个频道上抓取WIFI无线通信数据包；The first step is to periodically grab the WIFI wireless communication data packet on each channel of 2.4 GHz and 5.8 GHz;

第二步，解析各数据包的802.11协议帧头，从帧头的BSSID字段、Source address字段、Destination address字段中提取出MAC地址；In the second step, the 802.11 protocol frame header of each data packet is parsed, and the MAC address is extracted from the BSSID field, the Source address field, and the Destination address field of the frame header;

第三步，系统判定获取到的手机MAC是否为真实MAC地址，若不是真实MAC地址，解析报文获取曾经关联过的SSID信息；In the third step, the system determines whether the obtained MAC address of the mobile phone is a real MAC address, and if it is not a real MAC address, parses the message to obtain the SSID information that has been associated;

第三步中判断是否真实MAC地址的技术原理如下：The technical principle of judging whether the real MAC address is in the third step is as follows:

随机mac Random mac

X？:XX:XX:XX:XX:XXX? :XX:XX:XX:XX:XX

2,3,6,7,a,b,e,f2,3,6,7,a,b,e,f

当？＝2,3,6,7,a,b,e,f时，是随机macwhen? =2,3,6,7,a,b,e,f, is a random mac

如下图所示b2的值判断随机macThe value of b2 is judged as random mac as shown in the figure below.

第四步，发送Beacon报文和probe response报文，报文携带缓存SSID或者常用SSID信息；The fourth step is to send a Beacon packet and a probe response packet, where the packet carries the cached SSID or the commonly used SSID information.

第五步，获取手机回应的报文解析真实WIFI MAC地址。The fifth step is to obtain the real WIFI MAC address of the message that the mobile phone responds to.

人流预警系统，通过移动终端MAC数据的采集，大量MAC数据汇总到后台服务器，后台服务器计算出街道实时人流量。当实时显示人数达到或超过警戒值，引导人流分流。The human flow early warning system collects a large amount of MAC data to the background server through the collection of MAC data of the mobile terminal, and the background server calculates the real-time traffic of the street. When the number of real-time displays reaches or exceeds the alert value, the flow of people is diverted.

以上所述仅是本发明的优选实施方式，本发明的保护范围并不仅局限于上述实施例，凡属于本发明思路下的技术方案均属于本发明的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明原理前提下的若干改进和润饰，这些改进和润饰也应视为本发明的保护范围。 The above description is only a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiments, and all the technical solutions under the inventive concept belong to the protection scope of the present invention. It should be noted that those skilled in the art should be considered as the scope of protection of the present invention without departing from the principles of the invention.
