Human Body Communication Telematics Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle telematics systems rely on fixed devices and GPS signals, which limit service availability when the vehicle is not in use and can suffer from signal errors and security vulnerabilities, especially in areas with poor GPS reception.
Innovation Solution
A telematics system using human body communication for authentication and control, where a portable device transmits authentication keys through the user's body to control vehicle functions such as door opening and starting, and provides services like accident reporting and data synchronization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If GPS signal is used for location determination and Bluetooth for communication, then vehicle door can be automatically opened and closed, but security problems arise and the technique is not available in areas with poor GPS reception
Solution Approach 1:
The patent replaces electromagnetic communication (Bluetooth) and satellite-based positioning (GPS) with human body communication and biometric authentication. The system uses the human body as a communication medium to transmit authentication information, eliminating dependency on external signal infrastructure and enhancing both security and availability.
Solution Approach 2:
The patent introduces the human body as an intermediary medium for authentication and communication. By using the user's body to transmit authentication keys and data, the system creates a secure, physical-layer communication channel that cannot be remotely hacked and works independently of GPS or Bluetooth infrastructure.
2Productivity
If fixed devices are installed in the vehicle for telematics service, then vehicle monitoring and control functions are provided, but services are limited when the user leaves the vehicle and additional devices are required
Solution Approach 1:
The patent makes the portable device universal by enabling it to function both inside and outside the vehicle. The device serves as a remote interface for vehicle control when outside, and maintains continuous authentication capability, eliminating the need for separate fixed installations and expanding service versatility across different user scenarios.
Solution Approach 2:
The patent merges the functions of fixed vehicle-installed telematics devices with a portable user device. By combining authentication, communication, and control functions into a single portable unit that works both inside and outside the vehicle, the system eliminates the need for separate fixed devices while maintaining full service capability.

AI summary
Disclosed are a telematics system using human body communication, a portable device having a telematics function using human body communication, and a method for providing a telematics service using human body communication. The telematics system using human body communication includes: a vehicle receiving an authentication key from at least one portable device through human body communication using a human body as a medium, and controlling the opening and closing of a door of the vehicle based on whether or not the received authentication key is valid; and a first portable device transmitting a first authentication key through a user's body in contact with the vehicle.
