Image Processing Setting History Deletion by Authentication State
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image processing apparatuses lack the ability to control the deletion of setting histories based on the operation state or setting state, such as user authentication effectiveness, leading to indiscriminate deletion of setting histories.
Innovation Solution
An image processing apparatus that includes a controller to identify setting histories for deletion based on the effectiveness of user authentication, allowing selective deletion control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If batch deletion of setting histories is performed using a delete operation button, then deletion operation is simplified, but deletion control cannot reflect operation state or setting state such as user authentication status
Solution Approach 1:
The patent makes the deletion control dynamic by checking the current operation state (whether user authentication function is effective) at the time of deletion request. The controller adapts the deletion behavior based on the authentication state, allowing deletion of all setting histories when authentication is effective, and deletion of only currently displayed setting histories when authentication is ineffective. This dynamic adaptation resolves the contradiction between operational simplicity and control versatility.
2Quantity of substance
If all setting histories are deleted indiscriminately, then storage space is freed, but unauthorized deletion or loss of important settings may occur
Solution Approach 1:
The patent implements feedback control by checking the user authentication status before executing deletion. The controller receives feedback about the authentication state and adjusts the deletion scope accordingly. When authentication is effective, the system confirms the user's authority before allowing comprehensive deletion, thus preventing unauthorized deletion while still enabling storage space management when properly authorized.
3Reliability
If deletion scope is restricted to currently displayed setting histories only, then unauthorized deletion is prevented, but deletion efficiency is reduced
Solution Approach 1:
The patent dynamically adjusts the deletion scope based on authentication status. When user authentication is effective, the system expands the deletion scope to include all setting histories, improving efficiency. When authentication is ineffective, it restricts deletion to only displayed histories, maintaining security. This dynamic scope adjustment resolves the contradiction between reliability and productivity.

AI summary
An image processing apparatus includes a storage capable of storing a setting history of a job related to image processing, and a controller that accepts a deletion request of the setting history, in which, when the deletion request of the setting history is accepted, the controller identifies the setting history to be deleted as a deletion target according to whether a user authentication function is effective, and performs deletion control of the identified setting history.
