Electronic Name Tag Security System with Face Image Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems in facilities with distributed base stations face challenges in monitoring and authenticating individuals, particularly in preventing unauthorized access and impersonation, as they rely on wireless mobile sensor nodes that can be switched or tampered with, and electronic business card systems require visitors to carry their own devices, making it difficult to detect abnormal behavior.
Innovation Solution
A security system comprising staff and guest electronic name tags with display units, wireless communication, and a sensor network that monitors and authenticates individuals, displaying their face images and attributes, and uses a gate device to control access, while a management device photographs and transmits face images for display on the name tags, enabling easy detection of abnormal behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless mobile sensor nodes are used for monitoring, then position tracking is achieved, but the system becomes vulnerable to switching and tampering
Solution Approach 1:
The patent uses fixed sensor nodes deployed throughout the facility as a stable reference framework, replacing the vulnerable mobile sensor nodes. These fixed nodes continuously monitor positions and transmit data to a central server, creating an immutable record of movements that cannot be switched or tampered with, thereby resolving the security vulnerability while maintaining position tracking capability
Solution Approach 2:
The patent introduces a central server as an intermediary between the fixed sensor nodes and the monitoring system. This server receives position data from multiple fixed sensors, processes the information, and generates the final monitoring results. This intermediary layer adds system complexity but provides centralized control and data management, improving security by preventing direct tampering with individual sensor nodes
2Ease of operation
If electronic business card systems are used for visitor identification, then visitor information can be displayed, but visitors must carry their own devices making abnormal behavior detection difficult
Solution Approach 1:
The patent employs automatic identification technology where the system actively detects and identifies visitors without requiring them to carry or activate personal devices. The fixed sensor nodes automatically capture visitor information and trigger the display of visitor photos and information on electronic name tags or display screens throughout the facility, making the system self-service oriented and eliminating the burden on visitors while improving detection capability
Solution Approach 2:
The patent implements a feedback mechanism where the system continuously monitors visitor positions and automatically displays their information on electronic name tags or display screens. When a visitor enters a new area or exhibits abnormal behavior, the system provides real-time feedback by updating displays or triggering alerts, enabling easy detection of abnormal behavior while maintaining ease of operation through automatic identification
3Measurement precision
If face images are displayed on electronic name tags, then visual identification is improved, but the system requires photographing devices and wireless communication units
Solution Approach 1:
The patent divides the system into distinct functional modules: fixed sensor nodes for data collection, wireless communication units for data transmission, a central server for processing, and electronic name tags for display. This segmentation allows each component to perform its specific function efficiently while the overall system benefits from modular design, reducing complexity despite the addition of multiple components
Solution Approach 2:
The patent employs multi-functional electronic name tags that serve multiple purposes: displaying face images for identification, providing visitor information, and potentially serving as access control mechanisms. The fixed sensor nodes also perform multiple functions including position tracking, identification, and data transmission. This multi-functionality improves face recognition accuracy while managing system complexity by consolidating multiple functions into single devices

AI summary
To ensure that guest abnormal behavior can be easily found by visual inspection. A security system includes a staff electronic name tag device (SENTD), a guest electronic name tag device (GENTD), a monitoring device, a guest management device, and a gate device. The SENTD displays the face image of the staff who is assigned with the SENTD. The GENTD includes a display unit and a first wireless communication unit. The display unit displays the face image of the guest to which the GENTD is assigned. The photographing unit photographs the face image of the guest in the facility and outside the monitoring area. The second wireless communication unit wirelessly communicates with the first wireless communication unit of the guest electronic tag unit. The holder registration unit transmits the photographed face image of the guest to the GENTD in the second wireless communication unit for display.
