Multi-Channel Audio Authentication via Proximity Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication systems are cumbersome, inconvenient, and insecure, requiring multiple steps and time-sensitive processes, leading to a negative user experience.
Innovation Solution
The use of multiple audio channels for authentication, where a user's voice command is captured by both a first device and a trusted, registered device in proximity, with an authentication server comparing the audio recordings to verify the user's identity and ensure the registered device is present, allowing for seamless and frictionless authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication methods use knowledge-based questions or one-time passwords, then user identity verification is achieved, but the authentication process becomes cumbersome and requires multiple steps within a short time duration
Solution Approach 1:
The system uses the user's own voice as the authentication factor. The user simply speaks naturally without needing to recall security questions or enter codes. The voice biometric system automatically extracts and verifies authentication features from the voice signal, making the process self-service and eliminating the need for multiple interaction steps.
Solution Approach 2:
The patent replaces mechanical interaction methods (typing passwords, answering questions, entering one-time codes) with acoustic/voice-based authentication. The system captures voice signals and uses biometric analysis to authenticate users, substituting the mechanical step-by-step verification process with a more natural and efficient voice-based system.
2Reliability
If multiple steps are required for authentication within a short time duration, then security verification is achieved, but negative user experience results
Solution Approach 1:
The system performs preliminary voice enrollment during a separate setup phase, storing the user's voice biometric template in advance. During actual authentication, the system only needs to compare the current voice sample against the pre-stored template, significantly reducing the time required for verification without compromising security.
3Ease of operation
If voice-based authentication is implemented, then user interaction is reduced and authentication becomes seamless, but the system must ensure the registered device and owner are present
Solution Approach 1:
The patent combines multiple verification factors into a single unified authentication process. It merges voice biometric verification with device presence detection (using proximity sensors or device communication) to ensure both the registered device and the legitimate owner are present. This integration maintains simplicity for the user while comprehensively addressing security concerns.

AI summary
Disclosed herein are embodiments of systems, methods, and products comprises an authentication server for authentication leveraging multiple audio channels. The server receives an authentication request regarding a user upon the user interacting with a first electronic device. The server requests the first device to transmit a first audio file of an audio sample to the server. The audio sample may be the user's audio command or a machine-generated audio signal. The server requests a second electronic device to transmit a second audio file that is the recording of the same audio sample to the server. The second electronic device is a trusted device in proximity of the first device and executes an authentication function to enable the recording and transmitting of the audio sample. The server determines a similarity score between the first audio file and the second audio file and authenticates the user based on the similarity score.
