Abstract

Provided are a location privacy protection method, device and system, the method comprising: generating an identifier update notification message transmitted to at least one access point (AP), the identifier update notification message comprising the first identifier and the second identifier information of a wireless terminal, the first identifier indicating that the identifier update notification message is transmitted by the wireless terminal; transmitting the identifier update notification message, such that the AP acquires a second identifier according to the second identifier information, and uses the second identifier as the identifier of the wireless terminal; and transmitting to the AP a subsequent message comprising the second identifier to indicate that the subsequent message is transmitted by the wireless terminal. The wireless terminal can periodically or aperiodically transmit the identifier update notification message for updating the identifier thereof, such that the identifier field value of the wireless terminal in the subsequent message is not fixed, thus avoiding the problem of disclosing and tracking the wireless terminal location due to the fixed identifier field value of a transmitting device in the message, and effectively protecting the location privacy of a user using the wireless terminal.

Description

technical field [0001] The present invention relates to the field of terminal privacy protection, in particular to a location privacy protection method, device and system. Background technique [0002] With the wide application of Wi-Fi (Wireless Fidelity, wireless fidelity) technology, gradually popular smart terminals all support the Wi-Fi technology. In this case, Wi-Fi-based indoor positioning applications are gradually becoming possible. The working process of positioning can be: [0003] First, the AP (Access Point, access point) sends a positioning configuration request frame to the terminal. The positioning configuration request frame includes information such as channel, multicast address, and period, where the channel refers to the channel used by the terminal to send the location track notification frame. The multicast address is a group address of a group of APs receiving the position track notification frame, and the group of APs may be one or more APs, and the...
