Image Processing Apparatus Application Alteration Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses face challenges in securely managing altered applications, particularly when a login application is modified, as immediate stopping of altered programs can lead to unrestricted access and resource issues due to limited memory capacity in low-cost devices.
Innovation Solution
An image processing apparatus and method that detects alterations in applications, determines the need for use restriction based on the altered application, and displays messages to restrict or allow access accordingly, ensuring secure operation even with limited resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the login application is immediately stopped when alteration is detected, then security is improved, but the apparatus can be freely used without authentication restriction
Solution Approach 1:
The patent applies local quality by differentiating the response to application alterations based on the specific application type and alteration location. Login applications receive strict stopping treatment when altered, while other applications may continue running. This selective approach maintains security for critical authentication functions while preserving usability for non-critical functions.
Solution Approach 2:
The patent segments the apparatus operations into authenticated and unauthenticated modes. When a login application is detected as altered, the system stops that specific application and transitions to a state where authentication restrictions are removed, allowing unrestricted access. This segmentation isolates the security breach to specific functional areas.
2Reliability
If another login application is prepared in storage for backup, then reliability is improved, but memory resources are consumed in low-cost apparatus
Solution Approach 1:
Instead of storing multiple complete login application copies in limited memory, the patent creates a backup by copying the login application's functional capability to a different storage medium (such as a removable storage device or external server). This reduces the memory burden on low-cost apparatus while ensuring backup availability.
Solution Approach 2:
The patent moves the backup storage from the same-dimensional memory space (internal RAM/ROM) to a different dimensional storage space (external storage, network storage, or removable media). This dimensional transition allows backup functionality without consuming precious internal memory resources of low-cost apparatus.

AI summary
The present invention provides an image processing apparatus comprising detecting alteration of any application held in the image processing apparatus; determining, in a case where alteration has been detected, whether or not the use of the image processing apparatus needs to be restricted based on the application in which alteration has been detected; and displaying, in a display unit and as a result of the determination, in a case where the use of the image processing apparatus needs to be restricted, a message indicating that alteration of the application has been detected, and restricting the use of the image processing apparatus, and in a case where the use of the image processing apparatus need not be restricted, display, in the display unit, a message indicating that alteration of the application has been detected.
