Voice Assistant Biometric Authentication via Tamper-Resistant Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional authentication methods, such as those using IDs and passwords, are inconvenient and prone to information leakage, especially in public settings like hotels where biometric authentication information is stored on voice assistants, raising concerns about data security and user resistance.
Innovation Solution
A system that includes an information processing terminal with a tamper-resistant storage unit for biometric data and a voice operation device capable of receiving voice inputs, processing requests, and communicating with an external system for authentication, where biometric authentication is performed on the terminal rather than the voice assistant, reducing the risk of data leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric authentication information is stored in a voice assistant device in a public place, then user convenience is improved, but security risk increases due to potential leakage
Solution Approach 1:
The patent extracts the biometric authentication information storage function from the voice assistant device and relocates it to a dedicated information processing terminal with tamper-resistant storage. This separation allows the voice assistant to maintain its convenience for voice-based operations while the security-sensitive biometric data is stored in a secure environment, thus resolving the contradiction between ease of operation and security risk.
Solution Approach 2:
The patent introduces an intermediary authentication process where the voice assistant device acts as a mediator between the user's voice input and the biometric authentication system. The voice assistant transmits authentication requests to the information processing terminal, which performs the actual biometric verification. This intermediary mechanism enables convenient voice-based access while maintaining security through remote authentication.
2Loss of time
If biometric authentication is performed on the voice assistant, then authentication speed is improved, but data security deteriorates due to storage vulnerabilities
Solution Approach 1:
The patent extracts the biometric data storage function from the voice assistant and places it in a dedicated terminal with tamper-resistant storage. This allows the voice assistant to quickly transmit authentication requests without compromising security, as the sensitive data remains in a secure environment while authentication operations proceed efficiently.
Solution Approach 2:
The patent implements preliminary registration of biometric authentication information in the information processing terminal before actual authentication is needed. This preliminary setup stores the biometric templates securely in advance, enabling fast authentication operations later without repeatedly accessing or transmitting sensitive data, thus maintaining both speed and security.
3Device complexity
If conventional ID and password authentication is used, then system complexity is reduced, but information security worsens due to leakage risks
Solution Approach 1:
The patent replaces the mechanical interaction of typing IDs and passwords with voice-based biometric authentication. Users simply speak their requests to the voice assistant, which automatically performs authentication without manual input. This substitution eliminates the complexity of remembering and inputting credentials while significantly improving information security through unforgeable biometric data and tamper-resistant storage.
Data Source
AI summary
A system including a mobile terminal having an authenticator, a TPM with tamper resistance and a voice assistant. The voice assistant makes a process request corresponding to voice input of a user to a server in accordance with the input, receives a biometric authentication request from the server, makes a request for a biometric authentication process to the mobile terminal of the user in accordance with the request for biometric authentication via wireless communication, and transmits an authentication result from the mobile terminal to a server. The mobile terminal executes the biometric authentication process using biometric information stored in the authenticator and the TPM in accordance with the request for the biometric authentication process from the voice assistant, and transmits an authentication result to the voice assistant.
