Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] The SSID in the preferred network list (hereinafter referred to as PNL) in the user's mobile device often contains rich user information, such as semantic information, user preference, user geographic location information, and the like. For example, "Xiaoming's iPhone 6", "Starbucks", "XX company", etc. These characters can often infer what kind of mobile device the user uses and where the user often goes. On the other hand, user preferences and identification can be inferred through SSID information, and cyber attackers can infer important private information such as the user's residence and company based on this, which undoubtedly provides opportunities for criminals.

[0025] The inventive idea of ​​the present invention is to add some SSIDs (called pseudo-SSIDs) that the user has never connected to the user's PNL, and the real inform...

Abstract

The invention discloses a wireless network user privacy protection method and a computer readable storage medium. The method comprises the steps that the PNL of a current user is obtained, and according to the real SSID of the current user, k SSIDs different from the real SSID are provided to serve as pseudo-SSIDs to be added into the current PNL of the current user to update the PNL of the current user, so that the SSID sent by the current user through a detection request frame includes the pseudo-SSIDs, wherein the real SSID is the SSID of a wireless network connected with the current user.A pseudo-SSID selection method includes the steps that the PNL and position information of the current user and PNLs of surrounding users are obtained, and the k SSIDs, with the highest score, not connected with the current user are screened out from the real SSIDs of the surrounding users to serve as the pseudo-SSIDs, so that PNL similarity of the current user and the surrounding users is improved, wherein the score is the score given by the current user for the SSIDs not connected with the surrounding users. By means of the method, the PNL of the user is blurred to protect privacy by addingthe pseudo-SSIDs.

Description

technical field [0001] The invention relates to the field of wireless network and wireless network user privacy protection technology, in particular to a wireless network user privacy protection method based on SSID information and a computer-readable storage medium. Background technique [0002] Nowadays, wireless local area network (Wi-Fi) has become a kind of infrastructure. In order to speed up the process of Wi-Fi connection, mobile devices usually save the service set identifier (Service SetIdentifier, SSID for short) of the Wi-Fi network it has connected to. ) list, known as the Preferred Network List (PNL). In the process of connecting to Wi-Fi, the SSID in the mobile device will be sent out through a probe request frame, and the corresponding wireless access point (AP) will respond with a probe response frame, and after passing the verification, it can connect to the network. According to previous studies, since SSID contains a wealth of information, some potential...
