Analog Phone Authentication Through Voice And PIN Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies face challenges in authenticating users interacting with wireless telecommunication networks, particularly with analog phones, as identifying the user and device is difficult, and existing methods require internet connectivity or sophisticated devices.
Innovation Solution
A system that uses a blockchain authentication system to authenticate users via analog telephones through voice samples and personal identification numbers, establishing a communication channel using a unique telephone number, and performing multi-factor authentication without requiring internet access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional authentication methods (IMEI, MSISDN) are used, then digital device identification is reliable, but authentication of analog phones is impossible
Solution Approach 1:
The patent introduces a communication channel as an intermediary between the analog telephone and blockchain authentication system. This channel enables voice-based authentication by transmitting voice samples from the analog phone through the communication channel to the authentication system, which then verifies the voice against stored blockchain records. This intermediary mechanism bridges the gap between legacy analog technology and modern digital authentication requirements.
2Reliability
If internet connectivity is required for authentication, then secure communication is achieved, but analog phones cannot be authenticated
Solution Approach 1:
The patent replaces the mechanical/internet-based authentication system with a voice-based acoustic system. Instead of requiring internet connectivity and digital device interfaces, the system uses voice samples transmitted through traditional telephony infrastructure. The voice authentication mechanism substitutes for complex internet-based protocols, enabling authentication through simpler, more universally compatible analog telephone interfaces while maintaining security through blockchain-verified voice templates.
3Reliability
If multi-factor authentication is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The patent creates a universal authentication system where a single communication channel handles multiple authentication functions. The same voice-based channel used for authentication also serves for user registration and verification. The blockchain system stores multiple types of authentication data (voice samples, device identifiers, user profiles) in a unified structure, allowing the system to perform diverse authentication tasks through a single integrated mechanism rather than separate specialized systems.
Data Source
AI summary
The system receives a call at a unique telephone number associated with a wireless telecommunication network and establishes a communication channel with a UE of a user. The system requests and receives a voice sample from the user and a PIN associated with the user. Using the voice sample and the PIN, the system performs a multi-factor authentication. Upon authenticating the user using the voice sample and the PIN, the system authorizes the user to make the modification to a blockchain. Upon failing to authenticate the user using the voice sample and the PIN, the system refuses to authorize the user to make the modification to the blockchain.
