Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network infrastructure struggles to manage unique identifiers for stations, particularly when randomized MAC addresses are used, leading to challenges in tracking devices and providing user-configurable privacy settings.
Innovation Solution
A method and system that allow a station to respond to a unique identifier request action frame from an access point, involving determining the unique identifier support status, configuring a user interface, and generating a response action frame with a unique identifier or zero length, enabling user control over identifier disclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If randomized MAC addresses are used for privacy protection, then user privacy is improved, but the ability to track devices and recognize stations throughout the network is lost
Solution Approach 1:
The patent segments the identification system into two distinct parts: randomized MAC addresses for privacy protection during wireless communication, and separate unique identifiers (UUIDs) for network-wide device recognition and tracking. This segmentation allows each identifier to serve its specific function without compromising the other, resolving the contradiction between privacy and device recognition.
Solution Approach 2:
The patent introduces a unique identifier (UUID) as an intermediary element that mediates between the randomized MAC address and the network infrastructure. The UUID acts as a stable bridge that enables network-wide device recognition while the randomized MAC address continues to provide privacy protection during wireless transmissions, thus resolving the tracking limitation.
2Adaptability or versatility
If a unique identifier is required for network access, then network management and device tracking are improved, but user privacy control and flexibility are reduced
Solution Approach 1:
The patent implements dynamic unique identifier configuration that adapts to user preferences and network requirements. The system can dynamically switch between requiring unique identifiers for network access and allowing randomized MAC addresses, based on user privacy settings and network policy, thus maintaining both network management capability and user privacy control flexibility.
Solution Approach 2:
The patent changes the parameter of identifier disclosure from fixed to variable. Users can control whether their unique identifier is disclosed to the network through configuration settings, and the system adapts its behavior based on this parameter change. This allows network management to function when identifiers are shared while preserving user privacy control when identifiers are hidden.
3Object-affected harmful factors
If randomized MAC addresses are used, then privacy is protected, but users experience perceived loss of utility due to frequent login requirements
Solution Approach 1:
The patent performs preliminary establishment of unique identifier associations during initial network access or pre-association phases. By setting up the unique identifier mapping before actual network usage, the system enables automatic recognition and session persistence, eliminating the need for frequent logins while maintaining privacy protection through randomized MAC addresses during communication.

AI summary
An exchange of messages between an access point and a station can be facilitated, wherein the access point requests a unique identifier from the station. The station initiates a secure connection with the access point prior to associating with the access point. The station may either respond with a message declining to provide a unique identifier or respond with a message including a unique identifier to be used by the access point for the station via the secure connection. The response from the station may include additional limitations on the use of the unique identifier by the access point. The access point may enforce different policies against the station depending upon how the station responds to the unique identifier request. A station can provide a user interface for the configuration of the unique identifier based on one or more configuration parameters including a unique identifier requirement message.
