Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication methods for vehicles, such as password and biometric authentication, are not sufficiently secure for accessing services and do not provide a simple, high-security solution for vehicle-related applications.
Innovation Solution
A method using a light-emitting device in a vehicle to send a token sequence to a light-detecting device in a portable electronic device, which is then compared to an authentication token by a remote server, allowing secure access to services without the need for wireless communication or biometric sensors, and incorporating location matching for enhanced security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If password authentication is used, then ease of operation is improved, but security is insufficient and may be compromised
Solution Approach 1:
The patent replaces the mechanical/password-based authentication system with an optical communication system. Instead of typing passwords that can be compromised, the system uses light-emitting devices to transmit visual token sequences that are captured by light-detecting devices, eliminating the need for traditional password entry while enhancing security through optical channel authentication.
Solution Approach 2:
The patent introduces light signals as an intermediary medium between the vehicle and portable device for authentication. The light-emitting devices in the vehicle transmit encoded token sequences through optical signals, which are then detected by light-detecting devices in the portable device, creating a secure intermediary channel that avoids direct wireless communication vulnerabilities.
2Reliability
If biometric authentication is used, then security is improved, but device complexity increases due to requirement of biometry sensor
Solution Approach 1:
The patent makes the vehicle's existing light-emitting devices (such as turn signals, brake lights, or other visible lights) serve a dual purpose: both for their original traffic control functions and for authentication token transmission. This eliminates the need to add separate biometric sensors or dedicated authentication hardware, as the universal light-emitting components are repurposed for security functions.
Solution Approach 2:
The system uses the vehicle's own existing light-emitting capabilities to perform authentication without requiring additional specialized sensors. The vehicle's standard lighting system serves itself by encoding authentication tokens in the light patterns, eliminating the need for external biometric sensing equipment while maintaining high security.
3Ease of operation
If wireless communication is used for authentication, then ease of operation is improved, but security may be compromised due to potential interception
Solution Approach 1:
The patent substitutes traditional wireless communication protocols with direct optical communication. Instead of transmitting data through wireless signals that can be intercepted, the system uses visible light emission and detection to transmit authentication tokens directly, eliminating the wireless communication vulnerability while maintaining ease of operation through visual perception.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This method provides a secure authentication process that eliminates the risk of typos and does not require the portable device to be paired with the vehicle, offering improved security and convenience by using light signals and location matching.
Implementation Method 1
sending, by flashing with a light-emitting device comprised in the vehicle, a token sequence based on the authentication token
Implementation Method 2
the token sequence is sent such that the token sequence is received by a light detecting device comprised in a portable electronic device
Data Source
AI summary
The present invention relates to a method and a system for authentication of a user for granting access to a service, the method comprising: receiving, by a vehicle control unit comprised in a vehicle, an authentication token based on a request for authentication for access to the service, the vehicle being in communicative connection with a remote server. A token sequence is sent by flashing with a light-emitting device comprised in the vehicle, the token sequence is based on the authentication token. The token sequence is received by a light detecting device. The token is compared by the server with the authentication token. When the token sequence is determined to match the authentication token, access is granted to the service. The invention also relates to a vehicle implementing the method.
