Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for secure methods to authenticate users and transmit sensitive information over communication networks, particularly in cloud-based services, to mitigate risks associated with passing personally-identifying and sensitive information between organizations and cloud-based services.

Innovation Solution

A system and method for authenticating registered users using a voice-activated device, which involves receiving user and device identifiers, calculating a risk score, processing spoken voice utterances, and comparing them to pre-existing voiceprints to generate and encrypt a security token, ensuring secure authentication without exposing sensitive information.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If sensitive information is transmitted over the Internet between organization systems and cloud-based services, then cloud-based services can be utilized for administrative tasks, but security risks increase due to potential interception of personally-identifying information

Engineering Contradiction:

Improveutilization of cloud-based servicesVSAvoidsecurity risks

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts sensitive personally-identifying information from the transmission path by implementing voice biometric authentication that processes voice data locally or through secure channels, preventing the exposure of sensitive information while still enabling cloud-based service utilization

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces voice biometric authentication as an intermediary layer between the organization's systems and cloud-based services, creating a secure verification mechanism that allows communication without directly exposing sensitive information

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If traditional authentication methods such as PIN entry or live agent intervention are used, then user authentication can be performed, but user convenience decreases and operational complexity increases

Engineering Contradiction:

Improveauthentication securityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements self-service authentication where users automatically verify their identity through voice biometrics during natural interactions with the IVR system, eliminating the need for manual PIN entry or live agent intervention while maintaining secure authentication

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent replaces mechanical authentication methods (keypad entry, agent verification) with voice biometric authentication, substituting physical interactions with acoustic field-based verification that is both more secure and more convenient

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

AI summary

Systems and methods for authenticating a user using a voice activated device. The method includes receiving first data representing a user identifier corresponding to a user and second data representing a device identifier corresponding to the voice activated device. The method further includes determining user metadata corresponding to the user identifier and a device audio type corresponding to the device identifier. The method also includes calculating a risk score based on the user metadata. The method further includes calculating a length of spoken voice utterance based on the calculated risk score. The method also includes receiving and processing third data representing a spoken voice utterance having the calculated length corresponding to the user using the voice activated device. The method further includes validating the user in response to determining that the processed third data substantially matches the voiceprint associated with the user.
