Image Forming Apparatus Job History Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Image forming apparatuses shared among multiple users face challenges in preventing illicit use of job execution history, as existing technologies do not adequately restrict access to sensitive information.
Innovation Solution
An image forming apparatus with a history display unit, selection acceptance unit, determination unit, and acceptance display unit that verifies user authority before allowing access to and reuse of job execution history, utilizing an authentication server to manage function restrictions and display only permitted information to users based on their access levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If job execution history is made accessible for reuse to improve user convenience, then user setting friendliness is improved, but security against illicit use deteriorates
Solution Approach 1:
An authentication server acts as an intermediary between users and the job execution history. The server verifies user credentials and authorities before allowing access to history information, mediating between the need for convenient history reuse and the need to prevent illicit use by unauthorized users
Solution Approach 2:
Different levels of access rights are assigned to different users based on their roles and permissions. The system displays only the portion of job execution history that each user is authorized to access, making the security restriction localized to each user's specific access rights rather than applying a uniform restriction to all users
Data Source
AI summary
Selection of a send job by a user is accepted in an execution history which displays the execution history of a send job for sending data to a destination. It is determined whether the user has an authority to execute the send job displayed in the execution history. If it is determined that the user has the authority, an item for reusing a destination used when the selected send job was executed is displayed in a screen including the execution history.
