Voice Payment Authentication via Cloud-Connected Biometric Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional voice interaction methods for smart speakers pose significant security risks, leading to errors and inefficiencies in voice payment systems, which have not matured for widespread market adoption despite efforts from manufacturers like Alibaba, Baidu, and Amazon.
Innovation Solution
A voice payment method that utilizes a cloud-connected system where voiceprint authentication is followed by secondary biometric authentication (fingerprint, facial recognition, password, or NFC) to enhance security, preventing voice simulation attacks and ensuring authorized transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voiceprint authentication is used for voice payment, then payment convenience is improved, but security is worsened due to vulnerability to voice simulation attacks
Solution Approach 1:
The authentication process is segmented into two distinct stages: first voiceprint authentication for convenience, then secondary biometric authentication for security. This segmentation allows each authentication method to perform its specialized function without compromising the other, resolving the contradiction between convenience and security.
Solution Approach 2:
Voiceprint authentication is performed as a preliminary action to verify the user's identity, followed by secondary authentication as a confirmatory action. This preliminary action establishes basic authentication while leaving room for enhanced security measures, thereby maintaining both convenience and security.
2Device complexity
If only voiceprint authentication is implemented, then device complexity is reduced, but security is worsened
Solution Approach 1:
The authentication system is segmented into a first authentication module (voiceprint) and a second authentication module (biometric). This segmentation allows the system to maintain relatively simple individual modules while achieving enhanced security through their coordinated operation, thus balancing complexity and security.
Solution Approach 2:
The cloud server acts as an intermediary that coordinates between the first electronic device (voiceprint authentication) and the second electronic device (biometric authentication). This intermediary enables secure multi-factor authentication without requiring complex local processing, thereby maintaining device simplicity while enhancing security.
3Reliability
If multiple authentication factors are required, then security is improved, but ease of operation is worsened
Solution Approach 1:
The authentication system is dynamic in its design: the second authentication module is activated only when the first authentication module succeeds. This dynamic conditional activation ensures that multiple authentication factors are applied only when necessary, maintaining ease of operation for legitimate users while enhancing security when needed.
Solution Approach 2:
The system employs feedback mechanisms where the result of the first authentication directly influences the second authentication. This feedback loop ensures that users experience smooth, convenient authentication flow while maintaining high security standards, as the system adapts its requirements based on the authentication progress.
Data Source
AI summary
A voice payment method and an electronic device are provided. The method includes: A first electronic device receives voice information of a user, where the voice information is used to indicate a payment operation performed by the user; when a voiceprint feature of the voice information meets a preset condition, the first electronic device requests a second electronic device to authenticate the user; the second electronic device prompts the user to perform an authentication process, where the authentication process includes one or more of fingerprint authentication, facial recognition, password authentication, verification code authentication, and near field communication NFC authentication; when authentication performed by the second electronic device on the user succeeds, the second electronic device indicates to the first electronic device that authentication performed by the second electronic device on the user succeeds; and the first electronic device completes the payment operation with a payment platform.
