Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic media sanitization is implemented, then data security and reliability are improved, but device compatibility and system complexity increase
Solution Approach 1:
The system performs self-characterization by automatically detecting storage device parameters, security layer compatibility, and health status without requiring manual intervention. The sanitization module autonomously selects and executes appropriate sanitization methods based on detected device properties, eliminating the need for users to configure complex settings while maintaining high reliability through automated decision-making
Solution Approach 2:
The system dynamically adapts sanitization parameters and methods based on detected device characteristics. By characterizing the target device and adjusting sanitization approaches according to specific device parameters, security layers, and health status, the system resolves the contradiction by making complexity management automatic rather than static
2Measurement precision
If comprehensive device characterization is performed, then sanitization accuracy is improved, but processing time and operational complexity increase
Solution Approach 1:
The system performs device characterization and health status assessment before executing sanitization operations. By pre-detecting storage device parameters, security layer compatibility, and potential issues, the system prepares the optimal sanitization approach in advance, ensuring accurate treatment while minimizing actual sanitization time through pre-planned methodology selection
Solution Approach 2:
The system uses detected device characteristics and health status as feedback to automatically select appropriate sanitization methods. This closed-loop approach ensures high sanitization accuracy by matching methods to specific device conditions while optimizing processing time through intelligent decision-making based on real-time device feedback
3Reliability
If health status verification is implemented, then data irretrievability is improved, but device rejection rate increases
Solution Approach 1:
The system adjusts its approach based on detected device parameters and health status. By characterizing each device and selecting sanitization methods appropriate to its specific condition, the system maintains high data irretrievability for suitable devices while preserving compatibility with a broad range of storage devices through adaptive parameter adjustment

AI summary
Disclosed is a computer-implemented media sanitisation method for automatically sanitising a computer-readable storage medium, the method, comprising: establishing a communications link between a target device and a media sanitisation module, wherein the target device includes a target computer-readable storage medium; sending, using the communications link, target device characterisation parameters from the target device to the media sanitisation module; automatically determining, at the media sanitisation module, a data sanitisation method associated with the target device characterisation parameters; automatically sending, using the communications link, an indication of the data sanitisation method from the media sanitisation module to the target device; and automatically executing, at the target device, the data sanitisation method to sanitise the target computer-readable storage medium.
