Authentication Policy Impact Analysis in Image Processing Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses, such as multifunction peripherals, lack the ability to predict the scale of password changes and potential operational failures when password policies are updated, making it difficult to manage user authentication effectively.
Innovation Solution
An image processing apparatus with a storage and controller that identifies authentication information not meeting new policy requirements, displaying the ratio of non-conforming passwords and user urgency levels, allowing for proactive management of password changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If password policy is changed to improve security level, then security level is improved, but it becomes impossible to predict the scale of password change and operational failure
Solution Approach 1:
The system performs preliminary analysis before applying the password policy change. The controller identifies and stores information about users whose passwords will be affected by the new policy, including the number of affected users and their user IDs. This preliminary action enables prediction of the scale of password changes and operational impact before the policy is actually enforced.
Solution Approach 2:
The system provides feedback to administrators about the impact of password policy changes. The controller displays the ratio of authentication information that no longer satisfies the new authentication requirement to all stored authentication information. This feedback mechanism allows administrators to understand the scale of changes required and make informed decisions about policy implementation.
2Reliability
If authentication requirement is changed to improve security, then security level is improved, but operational disruption increases
Solution Approach 1:
The system identifies affected users and their authentication information before the policy change is enforced. By storing this information in advance, the system enables proactive planning and resource allocation to minimize operational disruption when the password policy is applied.
Solution Approach 2:
The system provides quantitative feedback about the scale of impact through displaying ratios of affected authentication information. This allows administrators to assess the operational disruption expected and plan accordingly, potentially phasing in changes or providing advance notice to users to maintain productivity.
3Reliability
If password policy is changed to prevent unauthorized access, then security level is improved, but user management complexity increases
Solution Approach 1:
The system automatically performs the analysis and identification of affected users when a password policy change is made. The controller autonomously compares existing authentication information against the new authentication requirements and generates the impact assessment, eliminating the need for manual analysis by administrators.
Solution Approach 2:
The system provides automated feedback about the impact of policy changes through displaying the ratio of affected authentication information. This automated feedback reduces the complexity of user management by providing clear, quantifiable information about the scope of changes required without requiring manual counting or analysis.

AI summary
An image processing apparatus includes: a storage that stores authentication information; and a controller that controls access by a user on the basis of the authentication information. In the case where an authentication requirement is changed, the controller identifies the authentication information that no longer satisfies the authentication requirement, and displays a ratio of pieces of the authentication information that no longer satisfy the authentication requirement to all pieces of the authentication information stored in the storage.
