Image Forming Apparatus Presence Monitoring for Authentication Reset
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems, such as multifunction peripherals (MFPs), lack robust security measures to prevent unauthorized use after user authentication, particularly when users step away from the device before completing their tasks.
Innovation Solution
An information processing apparatus that monitors user presence and resets authentication information or operation screens when the user moves beyond a predetermined range, incorporating multi-factor authentication methods like short-distance wireless communication and card-based authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-factor authentication is implemented to enhance security, then security is improved, but device complexity increases
Solution Approach 1:
The authentication system is divided into multiple independent factors (card-based authentication, face authentication, and presence monitoring). Each factor operates as a separate verification layer, allowing the system to achieve high security through segmented authentication steps without requiring a single complex authentication mechanism.
Solution Approach 2:
The system performs preliminary authentication using card and face recognition before allowing access. The presence monitoring function is activated in advance to continuously verify user proximity throughout the operation session, preventing unauthorized access before it can occur rather than reacting to security breaches after they happen.
2Reliability
If continuous monitoring of user presence is implemented, then security is improved, but energy consumption increases
Solution Approach 1:
Instead of continuous real-time monitoring, the system employs periodic presence detection through camera capture at predetermined intervals. This periodic action maintains security monitoring functionality while significantly reducing energy consumption compared to continuous monitoring, as the camera and processing units are activated only at scheduled intervals rather than continuously.
Solution Approach 2:
The system uses the user's own presence and movements as the trigger for authentication and monitoring. The camera automatically detects when a user approaches or leaves the device, and the system self-regulates its monitoring intensity based on detected presence, reducing energy consumption when no users are present while maintaining security when users are detected.
3Reliability
If authentication information is reset when user leaves the predetermined range, then security is improved, but user convenience deteriorates
Solution Approach 1:
The system continuously monitors user presence and provides real-time feedback by detecting when a user enters or leaves the predetermined range. When a user leaves the range, the system automatically resets authentication information and displays warnings, creating a feedback loop that maintains security while allowing users to understand system state changes. This feedback mechanism balances security requirements with user convenience by transparently communicating when authentication will be reset.
Data Source
AI summary
An information processing apparatus comprising: a memory that stores user information of one or more users who are authorized to use a predetermined system, the user information including user identification information for identifying the user; and circuitry to monitor presence of a user who uses the predetermined system, authenticate the user based on the user information, and reset authentication information of the user or an operation screen of the predetermined system, when the circuitry detects that the user has left the predetermined system beyond a predetermined range after authentication of the user and before the user completes a use of the predetermined system.
