In-Vehicle Operation Restriction by External Terminal Identification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Information processing devices, such as in-vehicle systems, face the challenge of allowing flexible operation restrictions to prevent unauthorized access to functions, especially during vehicle operation, as existing technologies do not effectively differentiate between user and external terminal operations.
Innovation Solution
The device implements a system with a communication interface and user interface that identifies external terminal sources of operation requests, applying restrictions based on stored information to ensure that only authorized users, typically the driver, can operate critical functions during vehicle travel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If operation requests are accepted from external terminals, then accessibility and convenience are improved, but security and authorization control deteriorate
Solution Approach 1:
The patent segments operation requests into two distinct types: first operation requests from the user interface and second operation requests from external terminals. This segmentation allows different processing paths and restriction applications for each source, enabling selective control while maintaining accessibility from authorized sources.
Solution Approach 2:
The patent applies different restriction rules locally based on the request source. For second operation requests from external terminals, the system identifies the terminal and applies operation restrictions based on identification results, while first operation requests from the user interface are subject to different restriction logic. This local differentiation resolves the contradiction by allowing accessibility where appropriate while maintaining security where needed.
2Reliability
If operation restrictions are applied to all requests, then security is improved, but flexibility and adaptability deteriorate
Solution Approach 1:
The patent implements dynamic operation restrictions that adapt based on the situation. The restriction execution unit determines whether to apply restrictions based on the type of operation request and identification results from external terminals. This dynamic approach allows the system to be restrictive when necessary for security while remaining flexible and adaptable when conditions permit, resolving the contradiction between security and flexibility.
3Adaptability or versatility
If external terminal operations are permitted, then versatility is improved, but harmful factors increase
Solution Approach 1:
The patent introduces an intermediary identification process between external terminal requests and operation execution. The external terminal identifying unit acts as a mediator that verifies the source of second operation requests before allowing them to proceed. This intermediary layer filters out unauthorized operations while permitting legitimate ones, thus maintaining versatility while reducing harmful factors from unauthorized access.
Data Source
AI summary
The information processing device receives a first operation request from a user via a user interface or a second operation request from an external terminal via a communication interface, and when the first operation request is received, the information processing device executes an operation restriction based on the restriction information, and when a second operation request is received, the information processing device executes an operation restriction based on the requesting external terminal and the restriction information.
