Remote Operation Browser Segmentation for MFP Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Remote operation of information processing devices via user terminals often results in performance reduction due to browser operations, and there is a security risk when internal contents are accessed by external browsers.
Innovation Solution
The system employs a user terminal and information processing device connected over a network, where the device determines whether accessed contents are internal or external, and either runs a browser on the device or the terminal, ensuring internal contents are secured and external contents are handled by the terminal's browser, thus preventing performance reduction and maintaining security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the browser is run on the information processing device to display contents, then the user can access web pages and internal contents, but the device performance is significantly reduced and job execution becomes slow
Solution Approach 1:
The patent segments the browsing function from the information processing device by running the browser on the user terminal instead. This separates the content acquisition function (performed by the terminal's browser) from the device functions (print, scan, etc.), allowing the device to maintain high productivity while the user still gains web browsing capability through the remote operation interface.
2Productivity
If the browser on the user terminal is used to access internal contents, then device performance is maintained, but security of internal contents is compromised
Solution Approach 1:
The patent introduces the remote operation screen image as an intermediary between the user terminal and the information processing device's internal contents. The terminal's browser displays these remote screen images that show internal contents, allowing the user to view internal content without the browser directly accessing or exposing the actual internal data, thus maintaining security while enabling access.
3Ease of operation
If the remote operation screen image is displayed with the user terminal, then remote control is enabled, but browser operations cause performance reduction
Solution Approach 1:
The patent extracts the browser operation from the information processing device and relocates it to the user terminal. The terminal runs the browser locally and displays remote operation screen images received from the device, separating the browsing workload from the device's processing tasks. This allows remote control functionality to be maintained while preventing browser operations from degrading device performance.

AI summary
An information processing system (1) comprises a user terminal (3) and an information processing device (2). A remote operation screen image (G1) is displayed with the user terminal (3), and the information processing device (2) is operated by remote control via the user terminal (3). The information processing device (2) includes: a screen image controlling part for receiving operation information from the user terminal (3); a contents determining part (55) for determining if internal contents of the information processing device (2) are accessed by a browser when a received request requires start up of the browser; and a browser controlling part for starting up the browser on the information processing device (2) when the internal contents are accessed, and sending a browser start up instruction to start up a browser on the user terminal (3) when external contents are accessed.
