Passive Voice Authentication System for Secure Data Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user authentication methods, particularly biometric authentication, require active input and consume resources, leading to delays and increased resource consumption.
Innovation Solution
Implementing a passive voice authentication system that processes voice commands to authenticate users without the need for active input, using voice recognition to enable secure access to data by determining if a voice command is usable for authentication and switching between active and passive authentication schemes based on user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If active biometric authentication is used, then security is improved, but resource consumption and processing time increase
Solution Approach 1:
The system performs preliminary voice profile creation during an enrollment phase, storing extracted voice characteristics for later authentication. This preliminary action enables rapid comparison during actual authentication without requiring complex real-time processing, thus reducing authentication delay while maintaining security
Solution Approach 2:
The system creates a copy of the user's voice characteristics in the form of a voice profile during enrollment. This copied representation is stored and used for authentication comparisons, eliminating the need to process original complex voice data during authentication, thereby reducing processing time and resource consumption
2Reliability
If active biometric authentication is used, then security is improved, but resource consumption increases
Solution Approach 1:
The system creates a simplified copy of voice characteristics (voice profile) during enrollment and stores it for authentication. This copied representation requires minimal storage space and enables fast, low-resource authentication comparisons, significantly reducing processor and memory resource consumption during authentication while maintaining security
Solution Approach 2:
The system performs complex voice characteristic extraction and profile creation in advance during enrollment. This preliminary processing shifts the computational burden to the enrollment phase, allowing authentication to use pre-processed data with minimal resource consumption, thus resolving the resource consumption issue
3Ease of operation
If passive voice authentication is implemented, then ease of operation is improved, but authentication reliability may be compromised
Solution Approach 1:
The system creates a detailed voice profile copy during enrollment that captures distinctive voice characteristics. This comprehensive copied representation enables reliable authentication comparisons even with passive, natural speech input, maintaining security while improving ease of operation
Solution Approach 2:
The system performs thorough voice characteristic analysis and profile creation during the enrollment phase. This preliminary action ensures that sufficient authentication data is captured in advance, allowing passive authentication to proceed with high reliability without requiring active user cooperation during the actual authentication moment

AI summary
Various embodiments of the technology described herein alleviate the need to specifically request enrollment information from a user to enroll the user in a passive voice authentication program. The system can receive one or more spoken words from a user. The system can determine that a voice profile is usable for user authentication. The system can select at least one word from the one or more spoken words to enroll the user into a voice authentication program without requiring further interaction from the user. The voice authentication program enables access to secure data in response to receiving the at least one word spoken by the user. After enrollment of the user into the voice authentication program, at least one word spoken by the user is received, and the user is authenticated based on the at least one word.
