Vehicle Mobile Device Authentication via Locally-Perceivable Passcode
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Keyless entry systems for vehicles face issues such as the need for a fob for operation, which can be inconvenient, and remote network-based solutions that raise security concerns due to vulnerability to hacks.
Innovation Solution
A system and method for authenticating a mobile device to operate a vehicle using a locally-perceivable signal passcode, where a receiver generates a signal indicative of a passcode in response to an operation request, and the mobile device transmits information relating to the passcode for authentication, establishing a connection if it matches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote network-based control is used to eliminate the need for a fob, then ease of operation is improved, but security is worsened due to vulnerability to hacks
Solution Approach 1:
The patent introduces a locally-generated passcode as an intermediary authentication mechanism between the mobile device and the vehicle. Instead of directly connecting to remote networks, the system uses a locally-perceivable signal (visual or audible) that displays a passcode, which is then transmitted back to the vehicle through the mobile device. This intermediary step eliminates the need for continuous network connectivity while maintaining security, as the authentication occurs locally without exposing sensitive data to network vulnerabilities.
2Reliability
If a fob is required for vehicle operation, then security is improved, but ease of operation is worsened when the fob is left at home
Solution Approach 1:
The patent creates a functional copy of the authentication mechanism by using the mobile device to generate and transmit the passcode back to the vehicle. Instead of requiring the physical fob, the mobile device acts as a copy that can perform the same authentication function. The locally-perceivable signal provides the authentication data that would normally come from the fob, allowing the user to operate the vehicle without carrying the original fob while maintaining security through local authentication.

AI summary
A method of for authenticating a mobile device for operating a vehicle may include receiving, by a receiver of the vehicle, an operation request from the mobile device to actuate an operation of the vehicle and generating, by a controller of the vehicle, a locally-perceivable signal indicative of a passcode granting a connection with the mobile device, in response to the received operation request. The method may further include receiving, by the receiver of the vehicle, information relating to the passcode from the mobile device, and establishing the connection with the mobile device for actuating the operation of the vehicle if the received information is authenticated.
