Autonomous Vehicle User Authentication With Owner-Mediated Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle authentication systems require pre-registration of biological information, leading to inconvenience and potential unauthorized use, especially in scenarios where a second user tries to use an automatic driving vehicle without prior registration or when a user's authorization is revoked but their information remains stored.
Innovation Solution
A vehicle system that includes storing and authenticating personal information, communicating with registered destinations, and determining usage permissions through multiple authentication layers to ensure only authorized users can operate the vehicle, even if their information is not initially stored, by using a combination of first and second authenticating means and determining means.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If pre-registration of authentication information is required, then security is improved, but convenience and adaptability deteriorate
Solution Approach 1:
The system performs preliminary registration of authentication information for authorized users in advance. This allows the vehicle to recognize and authenticate these users quickly without requiring manual intervention at the time of use, thus maintaining security while improving convenience for registered users.
Solution Approach 2:
The system introduces an intermediary authentication process involving a first user (vehicle owner) and a second user (guest user). When a second user needs access, the first user mediates by providing authentication information, allowing the second user to use the vehicle without pre-registration. This resolves the contradiction by maintaining security through the intermediary verification while enabling flexible access.
2Reliability
If only pre-registered users can access the vehicle, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system pre-registers authentication information for authorized users, enabling them to access the vehicle conveniently without manual verification at the time of use. This maintains strict authorization control for registered users while improving ease of operation through automated recognition.
Solution Approach 2:
For users who have not been pre-registered, the system allows a registered first user to act as an intermediary by providing their authentication information. This enables the second user to access the vehicle conveniently without compromising security, as the intermediary verification ensures proper authorization.
3Ease of operation
If authentication information is stored permanently, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The system allows authentication information to be discarded (deleted) when authorization is no longer needed or when a user loses the right to use the vehicle. This can be done remotely by the vehicle owner, ensuring that even if physical access is possible, authentication will fail. This resolves the contradiction by maintaining ease of operation for valid users while improving security through the ability to revoke access.
Data Source
AI summary
A vehicle owned by an owner and previously used by a first user who previously exited the vehicle performs autonomous driving. The vehicle includes a memory, a wireless communicator, and a processor. The processor obtains data, such as a picture of a second user entering the vehicle and authenticates the second user when the second user's picture matches a picture stored in the memory. When this authentication fails, the vehicle telephones the owner or the first user to ask whether the second user should be authenticated. If the answer is yes, the processor actuates operation of the vehicle for the second user. If the answer is no, the processor instructs the vehicle to a) ask the second user to exit the vehicle, and b) move to a location specified by the owner or first user after confirming that the second person exits the vehicle.
