Wireless Security Status Check for Unlocking Encrypted Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Data storage devices (DSDs) face risks of unauthorized access to proprietary, confidential, or sensitive data when lost, stolen, or misplaced, lacking effective security measures to ensure data privacy and security.
Innovation Solution
A data storage device that wirelessly enquires about its security status from a server application before unlocking, transitioning to an unlocked state if secured, or performing data erase or backup operations if unsecured, using processors to manage security status and commands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the DSD stores encrypted user data and implements security measures, then data security is improved, but device complexity increases due to additional security management components and procedures
Solution Approach 1:
A server application acts as an intermediary between the user and the DSD security system. The server stores security status information and communicates with the DSD via wireless communication, offloading security management complexity from the device itself while maintaining strong security controls through centralized management
Solution Approach 2:
The system implements feedback mechanisms where the DSD continuously enquiries about its security status from the server application. This feedback loop ensures the device maintains appropriate security states (locked/unlocked) based on real-time security status information, improving reliability while automating security management
2Reliability
If the DSD implements continuous security status checking and automatic lock/erase operations, then data security is improved, but productivity decreases due to additional operational steps and time delays
Solution Approach 1:
The system performs preliminary security status checks before allowing data access operations. By enquiries about security status in advance and pre-configuring automatic responses (lock, erase, or unlock), the system ensures security is maintained while minimizing delays during actual data operations
Solution Approach 2:
The DSD autonomously responds to security status information from the server by automatically transitioning between locked and unlocked states, or performing data erase operations when unsecured. This self-service capability eliminates the need for manual security management by users, improving productivity while maintaining security
Data Source
AI summary
A data storage device comprises a data port configured to transceive data between a data source and the data storage device, a non-volatile storage medium, configured to store encrypted user data, and a wireless communication port, configured to wirelessly transceive data between a server application and the data storage device. In response to the operational status of the data storage device being locked, transmit, via the wireless communication port, a security status enquiry message to a server application. Receive, via the wireless communication port, from the server application, a security status of the data storage device, the security status indicating whether the data storage device is registered as being secured or unsecured. Receive, via the data port, an unlock request and, in response to the security status indicating that the data storage device is secured, transition the operational status of the data storage device from a locked state to an unlocked state.
