Wireless LAN User Identification via Face Recognition and MAC Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In public wireless LANs, identifying the user of a portable communication terminal engaged in suspicious activity is challenging due to the lack of direct access to communication terminal identification information, hindering immediate intervention in potential criminal activities.
Innovation Solution
A communication terminal identification information processing system that captures image information of a wireless LAN communication spot, recognizes individuals, and compares candidate communication terminal identification information to narrow down and output the specific identification information used by the recognized person, allowing for targeted intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If only communication terminal identification information is used to identify users in wireless LAN communication spots, then the system maintains privacy protection and communication security, but the ability to identify actual users for intervention in criminal activities is lost
Solution Approach 1:
The system segments identification into two layers: communication terminal identification (MAC address) for general privacy protection, and personal identification (face recognition) for security interventions. This segmentation allows the system to maintain privacy for ordinary communications while enabling identification when necessary
Solution Approach 2:
The system introduces a management server as an intermediary that receives both communication terminal identification information and face recognition results. This intermediary correlates the two types of information to identify users only when face recognition detects a registered individual, thereby enabling intervention capability while maintaining privacy for unrecognized users
2Difficulty of detecting and measuring
If face recognition and communication terminal identification comparison processing is implemented, then the ability to identify users engaged in suspicious activities is improved, but the system complexity increases
Solution Approach 1:
The management server performs multiple functions: it stores face recognition results, receives communication terminal identification information, performs correlation processing, and manages registered individual data. This multi-functionality consolidates complex processing in a single centralized system rather than distributing complexity across multiple devices
Solution Approach 2:
The system performs preliminary face recognition and registration of individuals beforehand. Face recognition results are stored in advance in the management server, so when communication terminal identification information is received, the system only needs to perform simple correlation matching rather than complex real-time analysis

AI summary
A communication terminal identification information identifying processing system includes a person recognition processing unit that performs person recognition processing based on image information obtained by capturing a wireless LAN communication spot by a capturing device, a communication terminal identification information acquisition processing unit that acquires communication terminal identification information, a communication terminal identification information storage unit that stores, for each person, candidate communication terminal identification information of the portable communication terminal used by the person, a communication terminal identification information comparison processing unit that compares the candidate communication terminal identification information of the portable communication terminal stored in the communication terminal identification information storage unit and the communication terminal identification information acquired in the communication terminal identification information acquisition processing unit, and generates new candidate communication terminal identification information, and an output processing unit that outputs a part or all of the candidate communication terminal identification information.
