Seatback Display Locking via Mobile Authentication in Passenger Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In-vehicle entertainment (IVE) displays in commercial passenger vehicles are accessible by other passengers when the user is not present, potentially exposing personal information.
Innovation Solution
A system using near-field communication (NFC) or Wi-Fi technology to securely lock and unlock IVE displays without requiring passcodes, involving a mobile device and a computer in the vehicle to exchange digitally signed payloads using a secret key for authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If displays are left accessible for passenger convenience, then ease of operation is improved, but security and privacy are compromised
Solution Approach 1:
The patent introduces a mobile device as an intermediary between the passenger and the display system. The mobile device communicates with the seatback display through NFC or Wi-Fi to transmit lock/unlock commands, serving as a mediator that enables secure access control without requiring direct interaction with the display interface itself
Solution Approach 2:
The patent replaces traditional mechanical access control methods (such as physical locks or keyboard passcode entry) with contactless digital communication protocols. NFC and Wi-Fi technologies enable the mobile device to transmit authentication data and control commands wirelessly, eliminating the need for physical contact or manual typing at the display
2Object-affected harmful factors
If passcode entry is required for security, then security is improved, but ease of operation deteriorates
Solution Approach 1:
The system enables the mobile device to automatically perform authentication and lock/unlock operations without requiring manual passcode entry. The passenger simply needs to have their mobile device in proximity or connected to the seatback system, and the authentication process occurs automatically through the established communication channel
Solution Approach 2:
The system performs preliminary authentication setup during the check-in process or initial seat assignment. Passenger information and authentication credentials are pre-configured and associated with specific seats before the journey begins, enabling automatic recognition and access control without requiring real-time passcode entry
3Object-affected harmful factors
If displays are locked for security, then security is improved, but access to legitimate users deteriorates
Solution Approach 1:
The system implements a feedback mechanism where the mobile device continuously maintains communication with the seatback display to transmit lock/unlock commands based on real-time passenger presence and authentication status. The display responds to these commands by changing its access state, creating a closed-loop control system that automatically adjusts security based on legitimate user needs

AI summary
A display in a commercial passenger vehicle can an option to be locked or unlock to enhance security. An example system for securing an in-vehicle entertainment (IVE) display in a commercial passenger vehicle comprises a mobile device and a computer. The mobile device comprises a first processor configured to secure a display located in the commercial passenger vehicle, where the first processor is configured to: obtain a payload; generate a first digitally signed payload as a first output of a first mathematical computation performed on the payload with a secret key; and send a first message comprising the first digitally signed payload and a lock command to instruct the display to lock the display. The computer is communicably coupled with the display and comprises a second processor configured to send a first instruction to cause the display to lock in response to a reception of the lock command.
