Smart Badge Dynamic Display for Secure Identity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ID cards lack security and efficiency, as they expose personal information when used outside the company premises, leading to potential leaks and limited functionality for authentication beyond identity verification and building access.
Innovation Solution
A smart badge with a communication unit, OTP storage, display unit, personal information storage, input unit, and control unit, enabling wireless communication, secure one-time password generation, and image switching based on user intent, integrated with an authentication system that manages access to company gates and apparatuses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal information is displayed on the ID card for identity verification, then identity confirmation is enabled, but personal information leakage risk increases
Solution Approach 1:
The ID card employs a dynamic display mechanism that switches between different states: inside the company, personal information is displayed for identity verification; outside the company, personal information is concealed. This dynamic adaptation resolves the contradiction by making the display state dependent on location context.
Solution Approach 2:
The system applies different display qualities to different locations: inside the company premises, the display shows personal information for verification purposes; outside the company, the display conceals personal information. This local differentiation resolves the contradiction by tailoring information visibility to specific spatial contexts.
2Device complexity
If the ID card is used only for identity confirmation and building access, then the system is simple, but functionality and efficiency are limited
Solution Approach 1:
The ID card system is enhanced with multiple functions: identity verification, building access control, and authentication for various company apparatuses through OTP generation. This multi-functionality resolves the contradiction by enabling a single device to perform diverse authentication tasks.
Solution Approach 2:
The system combines identity verification, access control, and apparatus authentication into a unified ID card system with OTP capability. This merging of functions resolves the contradiction by consolidating multiple authentication needs into one integrated solution.
3Ease of operation
If personal information is always exposed on the ID card, then identity verification is convenient, but security and user dissatisfaction increase
Solution Approach 1:
The display dynamically adjusts personal information visibility based on location: inside the company, information is shown for convenient verification; outside the company, information is concealed for security. This dynamic behavior resolves the contradiction by optimizing both convenience and security according to context.
