Voice Biometrics Gateway Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication methods for human user systems, especially in online banking and cloud security, are cumbersome and prone to fraud due to the need for multiple devices and steps, and do not effectively differentiate between the user and their possession, leading to poor user acceptance and vulnerability to theft.
Innovation Solution
The Integrated Voice Biometrics Cloud Security Gateway (IVCS Gateway) provides a triple factor authentication system that intercepts access requests, places a call to the user device, and prompts a voice response, comparing it against stored biometrics and secret phrases, allowing for non-binary access decisions and flexible callback methods to ensure secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hardware token authentication is used, then security is improved, but ease of operation deteriorates due to needing to carry and manipulate multiple devices
Solution Approach 1:
The patent extracts the authentication function from the physical hardware token and relocates it to the user's voice biometric data stored in the database. The voiceprint authentication server retrieves and compares voice biometric templates instead of requiring the physical token, thereby eliminating the need to carry and manipulate multiple devices while maintaining security through biometric verification
Solution Approach 2:
The patent replaces the mechanical/physical hardware token system with a voice biometric authentication system. Instead of requiring physical manipulation of a token device, the system uses acoustic signal processing to capture, analyze, and verify voice prints, substituting mechanical interaction with acoustic and computational processes that are more convenient for users
2Reliability
If triple factor authentication is implemented, then security is improved, but loss of time increases due to multiple steps and device handling
Solution Approach 1:
The patent merges multiple authentication factors into a unified voice biometric verification process. Instead of requiring separate steps for password entry, token verification, and biometric authentication, the system integrates these into a single voiceprint verification step that simultaneously validates identity and authorization, significantly reducing the time required while maintaining triple-factor security levels
3Reliability
If hardware tokens are used for authentication, then security is improved, but device complexity increases due to managing multiple devices
Solution Approach 1:
The patent makes the voice biometric system universal by implementing it across multiple platforms and access points. The voiceprint authentication server can verify user identities through various interfaces (phone calls, voice messages, integrated systems) without requiring different hardware tokens for different devices, thereby reducing overall system complexity while maintaining security across diverse access scenarios

AI summary
A triple factor authentication in one step method and system is disclosed. According to one embodiment, an Integrated Voice Biometrics Cloud Security Gateway (IVCS Gateway) intercepts an access request to a resource server from a user using a user device. IVCS Gateway then authenticates the user by placing a call to the user device and sending a challenge message prompting the user to respond by voice. After receiving the voice sample of the user, the voice sample is compared against a stored voice biometrics record for the user. The voice sample is also converted into a text phrase and compared against a stored secret text phrase. In an alternative embodiment, an IVCS Gateway that is capable of making non-binary access decisions and associating multiple levels of access with a single user or group is described.
