UHF Communication Unit Restricted Activation for Secure Long-Range Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic identification devices, such as passports and cards, face limitations in communication distance due to their near field communication (NFC) or high-frequency (HF) interfaces, which restrict their ability to communicate over larger distances while maintaining security.
Innovation Solution
Incorporating an ultra-high frequency (UHF) communication unit that can be restrictedly activated using a secured command through an NFC or HF interface, with options for temporary activation via a timer or limited sessions enabled by a one-time password or rolling passcode, to enhance communication range while mitigating security risks.

Engineering Contradiction Analysis
1Length of stationary object
If an ultra-high frequency (UHF) communication unit is added to increase communication distance, then communication range is improved, but device complexity and security risks increase
Solution Approach 1:
The communication functionality is segmented into two distinct units: a UHF communication unit for long-distance communication and an NFC/HF communication unit for short-distance secure activation. This segmentation allows the device to achieve extended communication range while maintaining security through the use of the secure NFC/HF interface for control operations.
Solution Approach 2:
The NFC or HF communication unit serves as an intermediary that mediates between the external environment and the UHF communication unit. It provides a secure activation command interface that controls when and how the UHF unit can be activated, thereby enabling long-distance communication while mitigating security risks through the secure short-distance interface.
2Ease of operation
If the UHF communication unit is activated for extended periods or multiple sessions, then communication convenience is improved, but security risks increase
Solution Approach 1:
The activation mode of the UHF communication unit is made dynamic and configurable. The system can operate in different modes (single session, multiple sessions, or continuous activation) depending on the security requirements and use case. This dynamic approach allows the device to balance convenience and security by adapting the activation behavior to specific operational contexts.
Solution Approach 2:
The security parameters of the UHF communication unit are made changeable through the secured activation command. The command can configure various parameters such as the number of allowed communication sessions, activation duration, and other security settings. This allows flexible adjustment of the balance between convenience and security based on specific operational requirements.
