Unique Password Generation for Secure Data Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security data storage systems face security risks due to shared unlock passwords and increased user costs and complexity when devices are locked, requiring new devices and re-downloaded data upon locking.
Innovation Solution
A data storage system and method that generates unique unlock passwords for each security information storage device using dynamic link libraries, allowing for secure and convenient interaction by uniquely identifying devices and managing unlock processes through a server and device collaboration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the same unlock password is used for all security data storage devices, then the ease of operation is improved, but the security is deteriorated
Solution Approach 1:
The patent segments the unlock password functionality by introducing two distinct passwords: a first unlock password for initializing new devices and a second unlock password for unlocking locked devices. This segmentation allows different password management strategies for different operational scenarios, resolving the contradiction between ease of operation and security.
Solution Approach 2:
The patent applies local quality by making the second unlock password device-specific rather than universal. Each security data storage device has its own unique second unlock password, which maintains security while allowing convenient unlocking of the specific device without requiring universal password knowledge.
2Reliability
If the security data storage device is locked after failed authentication, then the security is improved, but the ease of operation is deteriorated
Solution Approach 1:
The patent enables self-service by allowing users to initialize and set their own first unlock passwords for new devices without requiring administrator intervention. This self-service capability maintains security through proper locking mechanisms while improving ease of operation by eliminating dependency on external support for basic device setup.
3Reliability
If a new security data storage device must be used when the device is locked, then the security is improved, but the loss of information and user cost are deteriorated
Solution Approach 1:
The patent enables recovery of locked devices by introducing the second unlock password mechanism. Instead of discarding locked devices or requiring complete re-initialization, users can recover access by providing the second unlock password, which preserves both the security model and the information stored on the device.

AI summary
The present invention proposes a data storage system and method used for the security information interaction. Said data storage system used for the security information interaction comprises a security information storage device, an unlock password generating device and an unlock server. The data storage system and method used for the security information interaction disclosed in the present invention reduce the potential security risks due to the divulgement of unlock passwords, and reduce the complexity of the unlock process, as well as reduce the potential security risks existed in the generating and writing process of the unlock password on the whole.
