Always-On Listening Device for Transaction-Based Voice Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user authentication systems are vulnerable to fraudulent access due to reliance on static personal information or voice samples, which can be easily compromised by malicious actors, leading to potential financial account vulnerabilities.
Innovation Solution
Implementing a smart device-based authentication method that combines voice print analysis with transaction-based authentication questions, where the smart device relays audible responses to a computing device associated with a financial institution, allowing for dynamic adjustment of authentication requirements based on voice print matching, thereby enhancing security and reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional authentication systems use static personal information or voice samples, then the authentication process is simple to implement, but the security and reliability are compromised due to easy circumvention by malicious actors
Solution Approach 1:
The patent implements dynamic authentication questions that change based on transaction context, user behavior patterns, and risk assessment. Instead of static personal information questions, the system generates adaptive questions related to recent account activity, making the authentication process both more secure and context-aware while maintaining operational simplicity through automated question generation and analysis.
2Reliability
If more authentication questions are required, then the security and reliability of the authentication process is improved, but the user burden and time required for authentication increases
Solution Approach 1:
The system incorporates real-time feedback mechanisms that analyze user responses, voice print characteristics, and transaction context to dynamically adjust the number and difficulty of authentication questions. When confidence is high based on voice matching and transaction patterns, fewer questions are required. When uncertainty increases, the system adaptively requests additional verification, optimizing both security and user experience.
Solution Approach 2:
The patent changes the parameters of authentication by introducing voice print analysis as a new dimension of verification. Instead of relying solely on the number of correct answers to knowledge-based questions, the system evaluates voice characteristics, response timing, and transaction context parameters to determine authentication confidence, reducing the need for multiple questions while maintaining or improving reliability.
3Reliability
If voice print analysis is combined with transaction-based authentication questions, then the security and integrity of authentication is improved, but the complexity of the authentication process increases
Solution Approach 1:
The patent merges voice print analysis with transaction-based knowledge authentication into a unified authentication framework. The voice verification and knowledge-based questioning work together synergistically, where voice matching provides initial confidence and knowledge questions provide contextual verification. This combination is managed through integrated software that coordinates both methods, achieving enhanced security without requiring separate complex systems.

AI summary
Aspects discussed herein may relate to techniques for authenticating a user using transaction-based authentication questions. The transaction-based authentication questions may be provided to the user. The user may provide audible responses to the transaction-based authentication questions that may be captured by a smart device, such as an always on listening device. Authentication of the user may be based on voice analysis of the audible responses to the transaction-based authentication questions and/or based on the answers to the transaction-based authentication questions.
