Voice Controlled Portable Memory Storage Device Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable memory storage devices face security risks with traditional password and biometric solutions, and they often require cumbersome button controls, which are inconvenient for use in certain situations.
Innovation Solution
A portable memory storage device that uses a microphone to capture user voice input, processes it, and stores a voice template for authentication, allowing secure access and minimizing the need for physical buttons by enabling voice-controlled functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional password or biometric authentication is used, then security access is provided, but the system becomes vulnerable to hacking, forgotten credentials, or sensor complexity and expense
Solution Approach 1:
The patent replaces complex biometric sensors (mechanical/optical systems) with a voice recognition system that uses acoustic signal processing. The voice template authentication substitutes fingerprint sensors, cameras, or other complex biometric hardware with a microphone and signal processing algorithms, reducing device complexity while maintaining security.
Solution Approach 2:
The patent creates a voice template (acoustic copy) of the user's voice characteristics and stores it in memory for authentication. This template copying approach allows the system to verify identity without requiring complex real-time biometric sensing, simplifying the authentication mechanism while preserving security.
2Adaptability or versatility
If multiple buttons are provided for device control, then functionality is enhanced, but the device size increases and usability in certain situations deteriorates
Solution Approach 1:
The patent replaces physical buttons (mechanical control interfaces) with voice command recognition. Users can control device functions by speaking commands instead of pressing buttons, eliminating the need for multiple physical controls while maintaining full functionality. This substitution improves ease of operation in situations where button pressing is inconvenient.
Solution Approach 2:
The voice recognition system serves multiple functions: authentication, command control, and potentially other interactions. A single voice interface replaces multiple dedicated buttons, providing universal control capability that maintains versatility while reducing the number of physical components needed.

AI summary
A portable memory storage device (“device”) is provided. The device includes a microphone for receiving a user voice input; a controller that receives the voice input and creates a template; and a plurality of non-volatile memory cells for storing the template, wherein the template is used to authenticate the user for any subsequent user request for accessing the device and an application is launched when the device interfaces with a host system to enroll the user as an authorized user to access device functionality and/or access host system functionality.
