External Storage Security System Using ID Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing external data storage apparatuses lack robust security measures, allowing easy access and exposure of stored data to unauthorized individuals, particularly when the hard disc is separated from its case and connected to another device.
Innovation Solution
A security system for external data storage apparatuses that includes a key input unit for converting user-input IDs into electrical signals, a memory for storing preset IDs, and a control circuit for comparing input IDs, which drives the data storage based on the comparison result, rearranging storage sectors or recording unrecognizable data to prevent unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the external data storage apparatus uses a simple configuration for easy portability and convenient data management, then the ease of operation is improved, but the security protection capability deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-registering authorized terminal IDs in the storage apparatus before actual data access occurs. When a terminal attempts to access data, the system compares the terminal's ID against the pre-registered IDs to determine authorization. This proactive security measure is implemented without changing the basic simple configuration of the external storage apparatus, maintaining ease of operation while adding security protection capability.
2Ease of operation
If the hard disc is separated from the case and connected to another storage medium for easy data access, then the ease of operation is improved, but data exposure to unauthorized persons worsens
Solution Approach 1:
The patent introduces an intermediary security verification mechanism between the hard disc and the storage medium. When the hard disc is separated and connected to another storage medium, the system intercepts the data access request and performs ID comparison verification through the control circuit. Only if the terminal's ID matches a pre-registered ID will the data be allowed to access. This intermediary security check prevents unauthorized data exposure while still allowing easy data access for authorized users.
3Ease of operation
If simple data input and output operations are allowed without authentication, then the ease of operation is improved, but data damage from unauthorized access worsens
Solution Approach 1:
The patent implements preliminary authentication by comparing terminal IDs before any data input or output operations occur. The control circuit performs this ID comparison check in advance, and only after successful verification does it enable data operations. This ensures data integrity protection while maintaining operational simplicity for authorized users, as they experience no additional steps in the data operation process itself.
