Vehicle Speech Control via Portable Device Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional speech recognition-based vehicle control methods are insecure as they require direct spoken passwords, which can be exposed to unauthorized individuals, compromising authentication security.
Innovation Solution
A method utilizing a portable device, such as a wearable device, for private user authentication through speech and gesture recognition, where authentication data is transmitted separately from speech commands, ensuring secure validation before vehicle control is executed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If direct spoken passwords are used for user authentication, then authentication process is simple and fast, but security is compromised as passwords can be exposed to unauthorized individuals
Solution Approach 1:
The authentication process is segmented into two separate communication paths: one for transmitting the speech command and another for transmitting authentication data from the portable device. This segmentation allows the speech command to be processed publicly while authentication occurs privately through the portable device, resolving the contradiction between simple authentication and security.
Solution Approach 2:
A portable device (such as a wearable device) is introduced as an intermediary to handle authentication data transmission. This intermediary enables private authentication by relaying authentication information through a separate path from the speech command, preventing password exposure while maintaining authentication functionality.
2Reliability
If authentication data is transmitted through the same path as speech commands, then system complexity is reduced, but security is compromised as authentication information may be intercepted
Solution Approach 1:
The communication system is divided into distinct paths: a first path for speech command transmission and a second path for authentication data transmission from the portable device. This segmentation ensures that sensitive authentication information is isolated from the public speech command channel, enhancing security while maintaining manageable system complexity through clear path separation.
Solution Approach 2:
The portable device serves as an intermediary that transmits authentication data through a dedicated second path, separate from the speech command path. This intermediary approach creates a secure channel for authentication while keeping the overall system architecture organized and manageable.
Data Source
AI summary
A speech recognition based vehicle control method includes transmitting a speech command to a first server through a first path via a speech recognition service apparatus in response to a generation of the speech command, transmitting authentication data of a portable device and the speech command to the first server through a second path via the portable device in response to the generation of the speech command, and performing, by the first server, authentication of the portable device on the basis of the authentication data, and recognizing the speech command as a valid speech command when the authentication of the portable device is completed.
