Audio Token Authentication for Secure Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods for accessing secured resources are often cumbersome and insecure, requiring users to carry multiple identification factors and being vulnerable to deep fake attacks, which increase costs and burden for both users and organizations.
Innovation Solution
A method and system that uses audio signals transmitted to smart devices in a user's environment to authenticate identity by comparing ambient audio data with a reference signal, eliminating the need for physical credentials and providing an additional layer of security against deep fake attacks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional authentication methods (identification cards, key-cards, passwords) are used, then users can access secured resources, but users must carry and remember multiple identification factors which increases burden and complexity
Solution Approach 1:
The patent extracts the authentication factor from physical objects (cards, tokens) and human memory (passwords) and embeds it directly into the user's voice bioacoustic signature. The voiceprint server extracts and stores unique voice characteristics during enrollment, then uses these extracted features for authentication without requiring users to carry or remember separate credentials.
Solution Approach 2:
The patent replaces mechanical and manual authentication systems (physical cards, biometric scanners, password entry) with an acoustic field-based system. Voice bioacoustic authentication uses sound waves and acoustic processing to verify identity, substituting the need for physical credential presentation and manual authentication actions.
2Reliability
If multiple identification factors are required for authentication, then security is improved, but authentication time and user burden increase
Solution Approach 1:
The voice bioacoustic signature serves multiple authentication functions simultaneously. The same voiceprint can authenticate users across different secured resources and communication channels (phone, video conferencing, computer access) without requiring separate authentication processes for each, reducing both time and burden while maintaining security.
Solution Approach 2:
The system performs preliminary authentication by analyzing voice characteristics during the natural course of communication rather than requiring a separate authentication step. The voiceprint server continuously monitors and analyzes voice patterns during calls or interactions, authenticating users in real-time without interrupting the primary communication task.
3Adaptability or versatility
If computing devices are used for authentication, then access to digital resources is enabled, but devices can be compromised and identity verification becomes unreliable
Solution Approach 1:
The voiceprint server acts as an intermediary between the user and the secured resources. Instead of relying on the computing device itself for authentication, the system uses the voiceprint server to verify the user's identity through bioacoustic analysis, creating a trusted intermediary that cannot be compromised by device security issues.
Solution Approach 2:
The patent replaces device-based authentication mechanisms (which rely on hardware security and software integrity) with voice-based acoustic authentication. This substitution moves the trust foundation from potentially vulnerable computing devices to the user's inherent biological voice characteristics, which cannot be replicated or compromised in the same way.
Data Source
AI summary
A sound-based method and system of performing an authentication of a person in order to permit access to a secured resource is disclosed. The system and method are configured to transmit an audio signal to a remotely located smart device. When the smart device produces the audio signal, a nearby computing device captures the audio signal and provides the captured audio data to an authentication platform. The audio data is compared to the transmitted audio signal. The system can determine whether there is a match between the captured audio data and the transmitted audio data. If there is a match, the system verifies an identity of the person and can further be configured to automatically grant the person access to one or more services, features, or information for which he or she is authorized.
