Vehicle Virtual Key Slots for Shared Access Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing shared vehicle access lack efficient methods for authenticating and authorizing users, leading to difficulties in providing or denying access to vehicles based on user credentials and privileges.
Innovation Solution
A method and system that utilize virtual keys stored on a vehicle device, associated with specific user lists and access privileges, where credentials are used to determine access rights, and if not found, communicate with a reservation management device to obtain or update access privileges, with features like virtual key storage, expiry management, and status reporting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If virtual keys are stored locally on the vehicle device for quick access verification, then access authentication speed is improved, but device storage requirements and security risks increase
Solution Approach 1:
The system segments the access control data into two parts: virtual keys are stored locally on the vehicle device for quick authentication, while the complete user credential database remains on the centralized server. This segmentation allows fast local verification without requiring the vehicle device to store all user information, resolving the contradiction between authentication speed and device storage requirements.
Solution Approach 2:
The virtual key acts as an intermediary element between the user's full credentials stored on the server and the vehicle's access control system. The virtual key contains sufficient information for local authentication verification while being much smaller than complete user profiles, enabling fast authentication without requiring the vehicle device to store comprehensive user data.
2Adaptability or versatility
If multiple user lists and virtual keys are stored for different access privilege levels, then access control flexibility is improved, but system complexity increases
Solution Approach 1:
The system segments user access control into multiple virtual keys, where each virtual key corresponds to a specific user list and set of access privileges. This segmentation allows the vehicle to efficiently manage different access levels by storing only the relevant virtual keys needed for each situation, rather than managing one complex comprehensive access control system.
Solution Approach 2:
The system dynamically selects which virtual key to use based on the current authentication needs and user credentials. The vehicle device can switch between different virtual keys as needed, allowing flexible adaptation to different access scenarios while keeping the system manageable through on-demand key selection rather than static comprehensive configurations.
3Reliability
If real-time communication with reservation management device is implemented for credential verification, then access security is improved, but authentication time increases
Solution Approach 1:
The system performs preliminary action by pre-generating and storing virtual keys on the vehicle device before actual authentication is needed. These virtual keys are prepared in advance based on user credentials, so when authentication is required, the vehicle can quickly verify access rights using the pre-stored virtual key without needing to communicate with the reservation management device in real-time, thus maintaining security while reducing authentication time.
Data Source
AI summary
The present systems, devices, and methods relate to managing shared vehicle access. Vehicle access can be provided to a candidate user based on whether the user is included in a list of at least one user associated with a respective virtual key. Virtual keys can be created, or lists of at least one user can be updated to include the candidate user, to in turn provide vehicle access. Virtual keys can be stored in a plurality of virtual key slots, with vehicle access being provided based on a virtual key stored in an active key slot. Status reports can be sent to a reservation management device, for updating virtual keys or lists of at least one user.
