Solution Overview

Problem

Current authentication systems, especially in voice-based interactions, lack effective methods to ensure proper user authentication, leading to security risks due to inadequate verification processes.

Innovation Solution

A multifactor authentication system that utilizes a hypertext transfer protocol (HTTP) interface module to send and receive one-time passwords (OTPs) audibly, allowing users to recite OTPs to a device with a microphone and speaker, which translates the audio into a non-audible format for verification, ensuring secure authentication across various devices and systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional digital authentication methods are used, then security verification is maintained, but user interaction becomes limited to digital inputs only

Engineering Contradiction:

Improveuser interaction methodVSAvoidauthentication channel flexibility

Core Design Contradiction:

Ease of operationVSAdaptability or versatility

Solution Approach 1:

The authentication system is enhanced to accept multiple input modalities (digital input, voice recitation, audio transmission) through a unified authentication module. This allows the system to maintain security verification while adapting to various user interaction preferences and accessibility needs, making the authentication process more versatile without compromising security

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If voice-based authentication is implemented, then user interaction flexibility improves, but security verification capability becomes insufficient

Engineering Contradiction:

Improveauthentication channel flexibilityVSAvoidsecurity verification

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

An audio transmission module acts as an intermediary between the voice-based authentication challenge and the verification system. This intermediary captures the user's voice recitation, transmits it securely, and interfaces it with the existing verification infrastructure, thereby enabling voice-based authentication while maintaining the reliability of security verification through proven authentication protocols

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If multifactor authentication with audible OTP is implemented, then security is enhanced, but system complexity increases

Engineering Contradiction:

Improvesecurity verificationVSAvoidauthentication system structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The authentication module is merged with existing digital input and transmission capabilities, combining multiple authentication factors (knowledge-based OTP, voice recitation, audio transmission) into a single integrated flow. This merging approach enhances security through multifactor authentication while minimizing the increase in system complexity by leveraging existing infrastructure

Inventive Principle:

Principle #5Merging (Combining)

AI summary

The application describes an authentication process that incorporates voice commands with an HTTP interface module to perform a multifactor authentication (MFA) process. For example, a first computer system may initiate the MFA process by sending, with a HTTP interface module maintained by the first computer system, a request to initiate the MFA process to the second computer system. The MFA process may also transmit an one-time password (OTP) to a first user device. The first computer system may receive an audible recitation of the OTP from a second user device. The OTP may be parsed and used to generate an HTTP request. The HTTP interface module may send the HTTP request to the second computer system. When the second computer system authenticates the user based at least in part on the non-audible file, the first computer system may receive confirmation of authentication of the user to initiate the transaction.
