Voice Authentication Threshold Adjustment for Remote Access Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote access services, such as online banking, face security issues due to vulnerabilities in user authentication methods, particularly when users access services from different locations without necessary equipment, and varying technical competence levels among users.
Innovation Solution
A voice authentication method that compares user voice data to a stored voice template, adjusting authentication thresholds based on an enrolment counter and device attributes to authenticate users, allowing for secure access without requiring additional equipment and accommodating varying device usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional password-based authentication is used, then users can access services remotely, but security vulnerabilities arise from phishing, hacking, and user incompetence
Solution Approach 1:
The patent replaces traditional mechanical/password-based authentication systems with biometric voice recognition authentication. The voice biometric system captures and analyzes unique vocal characteristics (pitch, tone, frequency patterns) to authenticate users, eliminating reliance on passwords that are vulnerable to phishing and hacking while maintaining remote access capability
Solution Approach 2:
The patent transforms the authentication parameter from knowledge-based (passwords) to physiological-based (voice biometrics). By changing the fundamental authentication parameter to something inherent and difficult to replicate (voice characteristics), the system maintains ease of remote access while significantly improving security against traditional attacks
2Reliability
If card reader authentication is used, then security is improved, but user convenience deteriorates due to equipment access requirements
Solution Approach 1:
The patent enables the user's own voice to serve as the authentication key, eliminating the need for external authentication equipment like card readers. The voice biometric system uses the user's inherent physiological characteristics, making authentication equipment-free and always accessible while maintaining high security
Solution Approach 2:
The patent makes the authentication system universal by removing dependency on specific authentication equipment. Voice-based authentication can be performed from any location using any device with voice capture capability, making the system both secure and highly convenient for mobile users
3Ease of operation
If voice authentication is implemented, then convenience is improved by eliminating equipment requirements, but security may be compromised without adaptive thresholds
Solution Approach 1:
The patent implements dynamic authentication thresholds that adapt based on the enrolment counter value. The system transitions from a first threshold during initial enrolment to a second, more secure threshold after successful enrolment verification. This dynamic adjustment maintains convenience during setup while ensuring security is not compromised in operational mode
Solution Approach 2:
The patent uses feedback from the enrolment counter to adjust authentication behavior. The system monitors enrolment progress and modifies the authentication threshold accordingly, providing feedback-driven security adaptation that balances convenience and security based on the authentication stage
Data Source
AI summary
An authentication method. The method comprises comparing user voice data received via an electronic device to a stored voice template to determine a voice authentication parameter. A voice authentication threshold is determined and the voice authentication parameter is compared to the voice authentication threshold to determine whether to authenticate the user. Determining the voice authentication threshold comprises determining a current value of an enrollment counter, then comparing the current value of the enrollment counter to an enrollment counter threshold and determining whether the stored voice template is fully enrolled according to the result. If the stored voice template is fully enrolled, the voice authentication threshold is set to a first voice authentication threshold. If the stored voice template is not fully enrolled then a device attribute received from the electronic device is compared to a stored device attribute. If the received device attribute matches the stored device attribute, the voice authentication threshold is set to a second voice authentication threshold determined by the current value of the enrollment counter. If the received device attribute does not match the stored device attribute, the voice authentication threshold is set to a third voice authentication threshold.
