Voice Authentication Layer for Secure OTP Account Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing two-factor authentication methods, such as those used by banks, are vulnerable to fraudsters using techniques like SIM Swap and SS7 hacking, making it difficult to secure one-time passcodes (OTPs) from unauthorized access.
Innovation Solution
Implementing voice authentication by requiring users to provide a voice sample, which is biometrically verified before issuing the OTP, ensuring only the intended user gains access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If voice authentication is implemented to enhance security, then security against fraud is improved, but system complexity increases
Solution Approach 1:
The patent introduces a voice authentication intermediary system that sits between the user and the OTP delivery mechanism. This intermediary captures voice samples, performs biometric verification, and only releases the OTP to authenticated users. The intermediary approach enhances security by adding a voice-based identity verification layer without requiring fundamental changes to the existing SMS delivery infrastructure, thus resolving the contradiction between improved security and system complexity.
2Reliability
If voice authentication is added to the authentication process, then security is improved, but the authentication time increases
Solution Approach 1:
The patent implements preliminary voice authentication before OTP delivery. By requiring users to provide voice samples and undergo biometric verification before receiving the OTP, the system ensures that only authenticated users can access the passcode. This preliminary action approach improves security by verifying identity upfront, while the automated voice recognition process keeps the additional time requirement minimal compared to traditional authentication methods.

Data Source
AI summary
A method for providing a user with secure access to an online account, the method comprising: receiving, from an institution hosting the user account, a message containing data to be used in obtaining access to the user account, issuing a request to a communication device of the user to provide a voice sample to be used in authenticating the user, receiving a voice sample from the user, performing voice authentication based on the voice sample, and in the event the voice authentication is successful, providing the user with the data to be used in obtaining access to the user account.
