Fake Identifier for Secure Wi-Fi Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing Wi-Fi wireless access technologies face security concerns and expose location information of end devices when connecting to wireless local area networks, as they transmit device identifiers during the connection process, potentially revealing the device's location to unauthorized access points.
Innovation Solution
An end device transmits a probe request frame with a fake device identifier, determines if the access point is authenticated, and then connects using its authentic identifier to prevent location information leakage, utilizing a fake device identifier generating unit, a transmitting unit, a determination unit, and a connecting unit to ensure secure connection to authenticated access points.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a device transmits its authentic device identifier during the Wi-Fi connection process, then the connection process is simple and straightforward, but the device's location information is exposed to unauthorized access points
Solution Approach 1:
The patent applies the copying principle by creating a fake device identifier that copies the structure and function of a real device identifier. This fake identifier is used during the probe request and connection process to mask the device's actual location information, while still allowing legitimate authentication and connection to authenticated access points. The fake identifier is a constructed copy that serves the dual purpose of anonymity and functional compatibility.
2Loss of information
If a device uses a fake device identifier to mask its location, then location information security is improved, but the device complexity increases due to additional authentication mechanisms
Solution Approach 1:
The patent applies preliminary action by pre-establishing a list of authenticated access points before the device needs to connect. The device proactively determines which access points are authenticated based on this pre-obtained list, and only attempts connection to those authenticated access points using the fake device identifier. This preliminary preparation simplifies the runtime authentication process by filtering out unauthenticated access points in advance.
Solution Approach 2:
The patent uses an intermediary approach by introducing a fake device identifier as a mediator between the device and the access point. This fake identifier acts as a placeholder that masks the real device identifier during communication with access points. The intermediary fake identifier enables the device to communicate authentication information without directly exposing its real location identifier, thus mediating between security requirements and connection functionality.
3Adaptability or versatility
If a device transmits probe request frames to multiple access points to find available networks, then network availability and adaptability are improved, but location tracking by unauthorized access points increases
Solution Approach 1:
The patent applies copying by generating a fake device identifier that replicates the functional characteristics of a real device identifier. This fake identifier is then used in probe request frames transmitted to multiple access points, allowing the device to discover available networks while masking its actual location. The copy maintains the necessary protocol compatibility for network discovery while achieving location anonymity.

AI summary
Technology is disclosed for preventing classification of objects, e.g., in an augmented reality system. The technology can identify a set of objects to be classified, determine whether context information for one or more objects in the identified set of objects to be classified is identified as not to be employed during classification, and during classification of two different objects, include context information for one object but not the other.
