Electronic Entity Contact Remote Communication Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic entities, such as microcircuit cards, face challenges in preventing unintended data exchange during contactless communication, particularly with confidential information, as previous solutions like switches or capacitive switches are not fully effective and increase manufacturing costs, and lack flexibility in controlling access to contactless communication modes.
Innovation Solution
An electronic entity with means to manage data exchange through contact or remote communication by using activation information to authorize or inhibit data transmission/reception, allowing separation of data exchange operations on a temporal plane, and enabling configuration during personalization to control remote communication usage without modifying existing circuits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If contactless communication means are used, then practicality is improved (no precise positioning necessary), but security is worsened (risk of untimely data exchange)
Solution Approach 1:
The patent applies preliminary action by requiring prior activation of the contactless communication mode through a switch or capacitive switch before any data exchange can occur. This preliminary activation step ensures that the user intentionally enables the contactless mode, preventing unintended data exchange while maintaining the convenience of contactless operation when properly activated.
2Reliability
If a switch is added to the electronic entity to control contactless communication, then security is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies the extraction principle by removing the mechanical switch from the electronic entity and replacing it with a capacitive switch that is integrated into the existing circuit structure. This extraction of the physical switch element reduces device complexity and manufacturing cost while maintaining the security function of controlling contactless communication activation.
3Reliability
If a switch is added to control contactless communication, then security is improved, but manufacturing cost increases
Solution Approach 1:
The patent applies the extraction principle by removing the mechanical switch from the electronic entity and replacing it with a capacitive switch that is integrated into the existing circuit structure. This extraction of the physical switch element reduces device complexity and manufacturing cost while maintaining the security function of controlling contactless communication activation.
4Reliability
If capacitive switch is used instead of mechanical switch, then reliability is improved, but security control flexibility is worsened (lack of password protection)
Solution Approach 1:
The patent applies the dynamics principle by making the security control mechanism adaptable and configurable. The system can dynamically adjust its security requirements based on the communication mode and data sensitivity. This allows the capacitive switch solution to be enhanced with optional password protection or other security measures depending on the specific application requirements, thereby achieving both reliability and flexibility.
