Information Processing Device Remote Operation Security Timeout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing information processing devices lack the capability to prevent unauthorized operations when communication with an external device is lost during remote operations, potentially allowing unauthenticated users to perform sensitive actions, compromising security and data integrity.
Innovation Solution
An information processing device equipped with an authentication unit, an operation accepting unit, a communication unit, and a controller that, upon prolonged loss of communication with an external device, transitions the device into a state where only authorized operators can perform operations, ensuring secure mode changes and restarts are initiated only by authenticated users with specific authority.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If remote operation is enabled during communication failure, then operational continuity is maintained, but security risk increases due to potential unauthorized operations
Solution Approach 1:
The operation unit dynamically changes its accessibility based on communication status. When communication fails, the system transitions from allowing remote operations to restricting access, with automatic timeout-based state changes that balance operational continuity with security requirements
Solution Approach 2:
The system continuously monitors communication status and provides feedback to control operation unit accessibility. The timeout mechanism serves as a feedback loop that detects communication failures and triggers appropriate security responses, including automatic state transitions and operator notifications
2Adaptability or versatility
If operation unit remains accessible during communication failure, then operational flexibility is maintained, but unauthorized operations may occur
Solution Approach 1:
The system performs preliminary security checks by monitoring communication status before allowing operations. When communication failure is detected, the system proactively restricts operation unit access in advance, preventing potential unauthorized operations before they can occur
Solution Approach 2:
The timeout mechanism implements preliminary anti-action by automatically restricting access to the operation unit when communication failures are detected, counteracting potential unauthorized operations before they can compromise system security
3Reliability
If communication failure detection triggers immediate state change, then security is enhanced, but operational efficiency decreases due to frequent mode switches
Solution Approach 1:
The system uses periodic timeout-based state changes rather than immediate responses to communication failures. This periodic approach allows the system to maintain security through regular state transitions while avoiding excessive mode switches that would reduce operational efficiency
Solution Approach 2:
The timeout mechanism provides dynamic control over state transition timing, allowing the system to balance security requirements with operational efficiency by adjusting the sensitivity and frequency of state changes based on actual communication conditions

AI summary
An information processing device includes an authentication unit, an accepting unit, a communication unit, and a controller. The authentication unit is configured to authenticate an operator. The accepting unit is configured to accept an operation corresponding to authority of the operator authenticated by the authentication unit. The communication unit is configured to communicate with an external device. The controller is configured to, when a state of being unable to communicate with the external device continues for a preset time or longer while an operation permitted only to an operator having specific authority is remotely performed from the external device, perform control so as to bring about a state that is not a state where only the operator having the specific authority is able to perform the operation.
