Mobile Body Authentication Using Position and Time Collation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mobile body authentication techniques, such as those described in Patent Literature 1-3, are insufficient in preventing unauthorized usage of autonomously movable mobile bodies like unmanned aircrafts and autonomous robots, which poses a safety concern for their widespread adoption.
Innovation Solution
A mobile body authentication apparatus comprising an acquisition unit that gathers remote identification information, position information, and time information from autonomously movable mobile bodies, a collation unit that verifies this information, and an output unit that reports the results, preventing unauthorized movement by detecting spoofing or falsified information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing authentication methods (Patent Literature 1-3) are used, then authentication of mobile bodies is provided, but unauthorized usage cannot be sufficiently prevented due to spoofing vulnerabilities
Solution Approach 1:
The patent applies preliminary action by pre-registering authentication information (digital certificates, public keys, or secret codes) in the mobile body before operation. The authentication server stores authentication information in advance, and the system performs preliminary validation checks on position, time, and identification data before allowing operation. This prevents spoofing by ensuring that only pre-authorized mobile bodies with valid authentication information can operate legally.
2Measurement precision
If comprehensive authentication information collection is implemented, then authentication accuracy is improved, but system complexity increases
Solution Approach 1:
The patent segments the authentication system into distinct functional components: an authentication information acquisition unit that collects data, a collation unit that validates information against stored records, and an output unit that provides authentication results. The authentication information itself is segmented into multiple independent elements including mobile body identification, position information, time information, and operator information. This segmentation allows comprehensive authentication without overwhelming system complexity, as each component handles a specific aspect of the authentication process.

AI summary
A mobile body authentication apparatus capable of preventing an autonomously movable mobile body from illegally moving without permission is provided. A mobile body authentication apparatus includes at least one memory configured to store instructions, and at least one processor configured to execute the instructions to: acquire, from an autonomously movable mobile body, remote identification information, which is information for managing a remote operation of the mobile body, position information indicating the current position of the mobile body, time information that indicates the current time in the mobile body, and authentication information; and execute collation based on the whole of part of the information; and output the result of collation.
