Security Adapter for Mobile Device Data Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need to protect mobile device data when interacting with a computer, particularly in scenarios where the USB port may not be connected to a power adapter but to a computer system, posing risks of data transmission and malware infection, especially when connecting to unknown computers.
Innovation Solution
A system and method involving a security adapter that connects a mobile device to a computer, determines a security level based on various parameters, and establishes data transmission rules to ensure secure communication, including using a remote server to assess the security level and blocking or allowing data transmission based on predefined rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a security adapter blocks data transmission to protect mobile device data, then data security is improved, but data transmission functionality is worsened
Solution Approach 1:
The system performs preliminary security assessment by collecting parameters about the computer system before establishing data transmission. The security level is determined in advance based on these parameters, and only then is data transmission permitted or blocked. This preliminary action ensures security is evaluated before any harmful data exchange occurs.
Solution Approach 2:
The security adapter dynamically adjusts its behavior based on the determined security level. When security level is high, data transmission is permitted; when security level is low, data transmission is blocked. This dynamic adaptation allows the system to balance security and functionality based on real-time security conditions.
2Reliability
If built-in microcontroller filters data transmission, then data security is improved, but device complexity is worsened
Solution Approach 1:
The security adapter acts as an intermediary device between the mobile device and the computer. It collects parameters about the computer system, determines security level, and controls data transmission accordingly. This intermediary approach provides security filtering without requiring complex microcontroller logic within the adapter itself, as the security determination can be based on parameter comparison against known security criteria.
3Productivity
If user disconnects adapter to enable data transmission, then data transmission functionality is improved, but data security is worsened
Solution Approach 1:
The security adapter automatically performs security assessment and makes decisions about data transmission without requiring user disconnection or manual intervention. The system self-services by collecting parameters, determining security level, and automatically permitting or blocking data transmission based on the security assessment, eliminating the need for users to disconnect the adapter to enable functionality.
