Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic security labels, such as RFID and NFC, require special verification terminals and professional systems for authentication, making them inconvenient for users to use for real-time authentication anywhere, and traditional clock-type dynamic password cards are not suitable for the security industry due to their unpopularity and lack of portability.
Innovation Solution
A clock synchronized dynamic password security label validity real-time authentication system comprising an electronic label module, a user authentication terminal module, and an authentication service module, which generates and displays dynamic password data using a unique ID number, clock data, and random numbers, allowing for real-time authentication via image recognition and dynamic password algorithms, ensuring each label has a unique and time-limited password.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If RFID and NFC electronic labels are used for security authentication, then the security and anti-counterfeiting capability are improved, but the device complexity increases and special verification terminals are required
Solution Approach 1:
The patent replaces complex electronic verification terminals with a mobile terminal-based solution that uses camera imaging and software-based dynamic password verification. The mechanical/electronic RFID/NFC reading devices are substituted with a smartphone camera and authentication app, simplifying the verification terminal while maintaining security through dynamic password algorithms.
Solution Approach 2:
The patent creates a visual copy of the dynamic password and label information through camera imaging, transferring the authentication data from the electronic label to the mobile terminal's image processing system. This copying mechanism eliminates the need for specialized electronic readers while preserving the authentication capability.
2Reliability
If traditional clock-type dynamic password cards are used for authentication, then the dynamic password generation capability is improved, but the ease of operation deteriorates due to manual input requirements
Solution Approach 1:
The patent replaces the manual keyboard input mechanism with automatic optical character recognition (OCR) through camera imaging. The mobile terminal's camera captures the dynamic password from the label, and software automatically extracts and verifies the password, eliminating the need for manual typing and significantly improving ease of operation.
Solution Approach 2:
The system enables self-service authentication where the mobile terminal automatically performs password capture, extraction, and verification without requiring user intervention for manual input. The user simply positions the label in the camera view, and the system completes the entire authentication process automatically.
3Ease of manufacture
If static security labels such as laser, bar code, or dimensional code are used, then the manufacturing simplicity is improved, but the reliability deteriorates due to ease of copying
Solution Approach 1:
The patent transforms static security labels into dynamic ones by incorporating real-time clock-based password generation capability. The label displays continuously changing dynamic passwords that are valid only for specific time windows, making counterfeiting extremely difficult while maintaining manufacturing feasibility through integrated circuit or display technologies.
Solution Approach 2:
The patent changes the temporal parameter of the security label from static to dynamic by introducing time-based password validity. The label's authentication credential changes over time, with each password being valid only within a specific time window, thereby enhancing anti-counterfeiting capability while keeping the label structure manufacturable.
