Dual-Faced Protective Mesh for Memory Card Reader Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current memory card reader terminals face security vulnerabilities due to the accessibility of the memory card connector slot, which allows malicious intrusions and data interception, despite existing protection measures like electrical mesh protection, which offer only a limited level of protection.
Innovation Solution
The implementation of an electrical protection mesh configured on both sides of the memory card reader body, with conductive tracks extending through vias from the internal to the external face, increasing the protection surface and making it more difficult for malicious access, combined with a thermosetting resin and protective cover to enhance security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a memory card reader slot is provided for inserting memory cards, then the device can perform its intended function of reading memory cards, but the slot makes the interior of the terminal accessible from the exterior, creating security vulnerabilities
Solution Approach 1:
The patent applies preliminary anti-action by implementing an electrical mesh protection system that is activated before any potential intrusion occurs. The mesh is pre-configured with conductive tracks that will detect and respond to drilling, scratching, or other intrusive techniques aimed at accessing the memory card connector, thereby preventing security breaches before they can compromise the system.
Solution Approach 2:
The electrical mesh acts as an intermediary protective layer between the external environment and the sensitive memory card connector. This mesh with its conductive tracks serves as a mediator that detects intrusive actions and triggers security responses, blocking the direct path from external access points to the vulnerable connector without preventing legitimate memory card insertion.
2Reliability
If electrical mesh protection is implemented to protect the memory card connector, then security is improved, but the protection offers only a limited level of security against determined attackers
Solution Approach 1:
The patent enhances the electrical mesh protection by adding a three-dimensional dimension with conductive tracks that wrap around and extend into the recessed area housing the memory card connector. This multi-layered, spatially distributed mesh configuration increases the detection surface area and makes it more difficult for attackers to bypass the protection, thereby improving security without proportionally increasing system complexity.

AI summary
A memory card reader body includes proposed, on an internal face, a receiving recess to receive a memory card connector. The receiving recess has electrically conductive tracks forming a protective mesh for the memory card connector. The conductive tracks are such that they also extend on an external face of the memory card reader body through vias passing through the internal and external faces.
