Multifunction Machine USB Traceability and Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multifunction machines, such as All-In-One devices, lack effective traceability and security measures to prevent information leakage when using detachable USB memories, as they are easily removable and can be accessed by unauthorized individuals.
Innovation Solution
A multifunction machine with an interface unit for controlling USB memories, a management unit for tracking attachment and detachment history, and an authentication system to ensure only authorized users can access USB memory services, enhancing traceability and security by managing user identification and service usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If USB memory is made detachable for ease of use and data transfer, then ease of operation is improved, but security and traceability of information leakage deteriorates
Solution Approach 1:
The system performs preliminary authentication and user identification before allowing USB memory attachment and data access. The management unit records user information and attachment history in advance, so that when data leakage occurs, the source can be traced back to the specific user and time of attachment.
Solution Approach 2:
The system implements feedback mechanisms by continuously monitoring USB attachment/detachment events and recording them in a management unit. This creates a traceable history that provides feedback on who accessed what data and when, enabling security auditing and accountability.
2Reliability
If authentication and history management systems are added to track USB usage, then security and traceability are improved, but device complexity increases
Solution Approach 1:
The management unit is designed to perform multiple functions: authenticating users, tracking USB attachment/detachment events, storing history information, and providing traceability. By consolidating these functions into a single multi-functional component, the system improves security without proportionally increasing overall device complexity.
