Storage Device Concurrent Initialization for Faster Biometric Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices face challenges in achieving high operating speed and enhanced security performance simultaneously, particularly in the context of biometric security protection.
Innovation Solution
Concurrently performing device initialization and biometric recognition operations, allowing access to the storage device only after successful completion of both, thereby enabling immediate accessibility upon user authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If device initialization and biometric recognition are performed sequentially, then security is ensured through proper initialization completion, but initial access speed deteriorates due to sequential processing time
Solution Approach 1:
The system performs device initialization in advance before biometric recognition, so that when authentication succeeds, the device is already ready for immediate access without waiting for initialization to complete
Solution Approach 2:
The system overlaps the execution of device initialization and biometric recognition operations, allowing both processes to run concurrently and improving overall system responsiveness and access speed
2Loss of time
If device initialization is completed before biometric recognition, then security protocols are properly established, but access time increases due to sequential operation completion requirements
Solution Approach 1:
Device initialization is performed preliminarily before or during biometric recognition, reducing the time users wait for access after successful authentication
Solution Approach 2:
The system maintains continuous operation by overlapping initialization and recognition processes, eliminating idle waiting time while keeping the user interface simple and responsive

AI summary
A method is provided for operating a storage device having biometric security protection, including: simultaneously starting both a device initialization operation and a biometric recognition operation; and if the device initialization operation has completed and the biometric recognition operation has successfully completed, setting the storage device to a normal access mode permitting external access to the storage device in accordance with the biometric security protection, wherein the device initialization operation and the biometric recognition operation are performed concurrently.
