Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flash drives lack secure mechanisms to protect stored information from unauthorized access, especially when lost or stolen, as the data cannot be hidden from view.
Innovation Solution
A flash drive equipped with wireless communication capabilities, including near field communication components, that allows mobile devices to lock or unlock the flash drive remotely, control access, and set permissions for sharing and usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If flash drives are made lightweight and easy to carry for convenience, then portability is improved, but security against unauthorized access deteriorates
Solution Approach 1:
The patent replaces traditional mechanical password protection with wireless communication-based locking mechanisms. The flash drive incorporates a communication component that receives locking commands from mobile devices via wireless signals, eliminating the need for physical password entry and enabling remote locking without mechanical interaction.
Solution Approach 2:
The patent introduces a mobile device as an intermediary between the user and the flash drive. The mobile device communicates with the flash drive through wireless communication, allowing the user to lock or unlock the flash drive remotely without direct physical access or mechanical interaction with the flash drive itself.
2Ease of operation
If flash drives allow easy access to stored information, then ease of operation is improved, but information security deteriorates
Solution Approach 1:
The patent implements dynamic access control where the flash drive can transition between locked and unlocked states based on real-time commands from mobile devices. The locking mechanism is not static but can be dynamically changed according to user needs, allowing easy access when unlocked and secure protection when locked.
Solution Approach 2:
The system incorporates feedback mechanisms where the flash drive communicates its status and receives commands from mobile devices. The control component on the flash drive processes feedback signals and adjusts access permissions accordingly, enabling secure information protection while maintaining ease of access when authorized.
3Device complexity
If flash drives are designed with simple structure, then device complexity is reduced, but security functionality deteriorates
Solution Approach 1:
The patent makes the flash drive universal by enabling it to work with multiple mobile devices through wireless communication. The communication component and control component allow the flash drive to be controlled by different mobile devices, enhancing security capabilities while maintaining relative structural simplicity through multi-functional design.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances information security by allowing users to remotely lock and control access to the flash drive, preventing data leakage in case of loss or theft, and simplifying the process of managing permissions and usage.
Implementation Method 1
each of the communication component and the mobile communication component includes a near field communication component
Data Source
AI summary
A flash drive locked by using wireless communication that is applicable to a mobile device is provided. The mobile device includes a mobile communication component and a mobile control component. The flash drive includes a connection port, an information storing component, a communication component, an identification certificate component and a control component. The information storing component stores information. The identification certificate component stores identification information of the flash drive. When the communication component communicates with the mobile communication component, the communication component transmits a locking command generated by the mobile control component from the mobile communication component to the control component. The control component, according to the locking command, locks the identification certificate component and the data storing component, thereby prohibiting the flash drive from being identified and accessed by an electronic device having a slot into which the connection port of the flash drive is inserted into.
