Image Forming Device Identity-Based Display Control for Secure Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Service personnel face difficulties in providing effective support to users of image forming devices due to the challenge of grasping the current operation status remotely, especially when high-security document previews are displayed in a degraded state, which complicates secure remote access and support.
Innovation Solution
An image forming device equipped with a communication interface, user interface, and controller that performs remote display control, allowing secure remote access by determining the user's identity and adjusting the display mode to either show a full or restricted operation screen based on user identity, thereby enabling effective remote support while maintaining security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If preview screens for high-security documents are displayed in a degraded state, then security strength is increased, but ease of operation for remote support is worsened
Solution Approach 1:
The display quality of the preview screen is dynamically adjusted based on the operational mode. During normal local operation, the screen displays in full quality for optimal usability. When remote support mode is detected, the system automatically switches to degraded display mode to maintain security, and switches back to full quality when local operation is detected, thus resolving the contradiction between security and ease of operation through dynamic adaptation
Solution Approach 2:
Different display quality levels are applied to different operational contexts. The system maintains high display quality for local user operations while applying degraded quality specifically during remote support sessions. This local differentiation of quality ensures that security enhancements only affect the specific context where they are needed (remote access) while preserving optimal usability in the primary context (local operation)
2Ease of operation
If remote display control transmits full operation screen data, then ease of operation for remote support is improved, but security strength is worsened
Solution Approach 1:
The system changes the parameter of display quality when transmitting remote screen data. Instead of transmitting full-quality image data, the system modifies the quality parameter to produce degraded display data that maintains operational visibility for support personnel while reducing the security risk of transmitting complete document images over the network
3Productivity
If service personnel access operation status remotely, then productivity of support is improved, but security risk increases
Solution Approach 1:
A remote display control system acts as an intermediary between service personnel and the image forming device. This intermediary component enables remote access and support while implementing security measures through degraded display mode, thus facilitating productivity improvement without directly exposing service personnel to the full security risks of direct system access
Data Source
AI summary
An image forming device according to aspects of the present disclosure, including a memory, a communication interface, a user interface, and a controller. The controller configured to perform of obtaining identification information identifying a user, determining a display mode based on the identification information. The display mode is determined to be a first mode when the obtained identification information identifies a first user, the display mode being determined to be a second mode when the identification information identifies a second user. The controller transmits remote data to an information processing device. The remote data causes the information processing device to display a remote screen reproducing an operation screen when the display mode is the first mode, while causes the information processing device to display a remote screen reproducing a restricted screen when the display mode is the second mode.
