Remote Control Security via Position Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing remote control systems for devices like cars lack sufficient security measures, allowing unauthorized access and control.
Innovation Solution
A processing device that acquires and determines the position and relative positional relationship between a remote-controllable device and a terminal device, permitting control only if certain conditions are met, thereby enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If remote control is permitted without position verification, then ease of operation is improved, but security deteriorates
Solution Approach 1:
The system performs preliminary verification of the terminal device's position and relative positional relationship with the remote-controllable device before permitting control. This advance check ensures that only authorized devices can establish control connections, preventing unauthorized access while maintaining ease of operation for legitimate users.
Solution Approach 2:
The system introduces an intermediary verification mechanism that mediates between the terminal device and the remote-controllable device. This intermediary layer checks positional information and relational conditions before allowing control transmission, thereby enhancing security without significantly complicating the user experience.
2Reliability
If position verification is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The system employs universal positioning technologies (such as GPS or network-based location services) that are already integrated into modern terminal devices and remote-controllable devices. This multi-functional approach allows the same hardware components to serve both their primary functions and positioning verification, reducing the need for additional specialized equipment and minimizing system complexity.
3Reliability
If multiple verification conditions are enforced, then security is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary verification of positional information and relational conditions before control is requested. By checking these conditions in advance and caching verification results, the system minimizes the time required for actual control operations, as the heavy verification work is completed beforehand rather than in real-time during control execution.

AI summary
A processing device includes a remote-controllable device position information acquisition unit that acquires information on a position of a remote-controllable device, a relative positional relationship information acquisition unit that acquires information on a relative positional relationship between a terminal device transmitting instructions to request control regarding the remote-controllable device via another device having a communication function not included in either the processing device or the remote-controllable device by communicating with the other device, and the remote-controllable device, a determination unit that determines if each condition regarding the position of the remote-controllable device and a condition regarding the relative positional relationship is satisfied on the basis of the acquired information, and determines whether to permit the terminal device to perform the control regarding the remote-controllable device according to a result of the determination, and a control unit that performs control.
