Voiceprint Authentication via Telephone Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current authentication and payment systems, especially for transactions not conducted face-to-face, are vulnerable to fraud and require multiple steps, which can lead to increased transaction costs and customer dissatisfaction due to the need for additional security measures.
Innovation Solution
A secure authentication and payment system utilizing the unique telephone numbering system for rapid and transparent transactions, where a customer's telephone number serves as the primary identifier, and a PIN or password as secondary authentication, allowing for single-session transactions over a telephone or IP telephony network without the need for special apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication systems (ATM cards, PINs, signatures) are used, then security is improved, but device complexity and transaction cost increase
Solution Approach 1:
The patent extracts the authentication function from complex physical devices (ATM cards, readers, signature pads) and implements it through a simplified voice-based system using existing telephone infrastructure. The authentication is performed by comparing voiceprints during a phone call, eliminating the need for multiple physical authentication components.
Solution Approach 2:
The patent introduces a voiceprint database as an intermediary that stores and compares voice authentication data. This mediator enables secure authentication without requiring direct physical interaction between customer and merchant, using the telephone network as the communication channel.
2Reliability
If multiple authentication steps are required, then security is improved, but transaction time and customer patience increase
Solution Approach 1:
The patent combines multiple authentication functions (identification, verification, authorization) into a single voice-based authentication step during the telephone conversation. The voiceprint comparison occurs in real-time during the call, merging what would traditionally be separate authentication stages into one unified process.
Solution Approach 2:
The voiceprint database is pre-populated with authenticated voice samples before transactions occur. This preliminary authentication setup allows for rapid verification during actual transactions, eliminating the need for multiple real-time authentication steps while maintaining security.
3Reliability
If robust authentication is implemented, then fraud prevention is improved, but ease of operation decreases
Solution Approach 1:
The system performs automatic voiceprint authentication without requiring the customer to manually complete forms, sign documents, or remember complex passwords. The authentication happens automatically by analyzing the customer's voice during the telephone conversation, making the process as convenient as a regular phone call while maintaining strong security.
Solution Approach 2:
The patent replaces mechanical authentication methods (physical signatures, card swiping) with acoustic authentication (voiceprint analysis). This substitution maintains security while significantly improving ease of operation, as speaking is a natural, effortless action compared to manual authentication tasks.
4Reliability
If special authentication apparatus is used, then security is improved, but accessibility and universality decrease
Solution Approach 1:
The patent leverages the universal telephone network as the authentication platform, making the system accessible to anyone with a telephone without requiring specialized devices. The voiceprint authentication methodology can be applied across different telephone systems and networks, providing broad adaptability and universality while maintaining security.

AI summary
A transaction and payment and processing system securely conducts transactions over the public telephone network. The transactions may be between and among entities of any type such as individuals, merchants, utilities, banks, etc. Nothing more than access to a telephone is required after initial registration of a user.
