Problems solved by technology

If the user's mac address has already been obtained, then through the big data in the background for matching (because the mac address is unique), often a mobile app will require the user to register the mobile phone number to obtain the verification code when registering, and automatically obtain the user The IMEI code of the device, the combination of these three, the user has been accurately located, and the user's privacy will be violated

Embodiment Construction

[0016] The present invention will be further described below in conjunction with drawings and embodiments.

[0017] Take the wireless network connection initiated by WIFI device A and WIFI probe B as an example:

[0018] Step 1. WIFI device A sends a probe frame to WIFI probe B. At this time, the mac address in the probe frame has been randomly processed. At this time, WIFI probe B has sniffed the current fake mac address, and the real information has not been leaked.

[0019] Step 2. WIFI probe B sends a beacon frame to WIFI device A. After receiving it, WIFI device A finds that it is an unfamiliar link, and actively asks the user whether to connect. The user observes the current ap. If the current ap is not the one he wants to connect to, he will Reject the link. At this time, the wifi connection caused by the unfamiliar link fails, and the real information is not leaked.

Abstract

The invention discloses a sensitive data protection method for preventing a wifi probe. The method comprises the following steps that: 1, a user starts a wifi function of equipment device , starts a random mac address of the device, and puts a real Mac address of the user in a probe frame; 2, a mac-ap address dictionary is created to bind and store mac and ap information in a database; when the user receives the beacon frame, a mac address in the frame is compared with the database of the user, and if the mac address in the frame is a strange link, the current mac address and ap information are bound and added into the database, and meanwhile whether the user links or not is actively inquired; if the link is selected, a mark is safe, and the same address automatic connection is received later; and if the connection is selected to be disconnected, the non-secure address is marked, and inquiring is not operated within the appointed time. The problem that user privacy information is easily and actively exposed to the wifi probe due to own defects of the wifi protocol is solved.

Description

technical field [0001] The invention specifically relates to a method for protecting sensitive data against Wifi probes. Background technique [0002] Wifi, also known as mobile hotspot, is the trademark of the Wi-Fi Alliance manufacturer as a product brand certification, and is a wireless local area network technology based on the IEEE 802.11 standard. In network communication, data is encapsulated into a frame, and a frame refers to a data block in communication. The frame structure is divided into several categories: control frame, management frame, data frame. Among them, the beacon frame (BeaconFrame): mainly to announce the existence of a certain AP network. Regularly send beacon frames to let mobile WiFi devices know the existence of the network, so as to adjust the necessary parameters to join the network; probe request frame (ProbeRequest): WiFi devices will use ProbeRequest frames to scan the area where there are currently 802.11 network. [0003] A WiFi probe ...
