Printer Authentication Screen Adaptation for Confidential Jobs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses lack effective personal identity authentication mechanisms that adapt operation screens based on user authentication and fail to ensure secure execution of private and confidential print jobs, leading to operational complexity and potential security breaches.
Innovation Solution
An image forming apparatus with a processor, display, and fingerprint sensor that authenticates users based on identification information, displays appropriate operation screens, and restricts or suspends private and confidential print jobs according to authentication status, ensuring secure execution and user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal identity authentication is implemented with filtered job list display, then security is improved, but operation complexity increases due to multiple screen switching requirements
Solution Approach 1:
The operation screen dynamically changes based on authentication status and job queue state. After authentication, the system automatically displays either a filtered job list or a shortcut key screen depending on whether confidential jobs are present, eliminating the need for manual screen switching and reducing operational complexity while maintaining security
Solution Approach 2:
The system performs preliminary authentication before displaying the job list, and preliminarily determines whether confidential jobs are present. This preliminary action allows the system to pre-configure the appropriate display mode (filtered list or shortcut key screen), preventing the need for subsequent screen switches and simplifying the user workflow
2Loss of information
If job list screen is displayed immediately after authentication, then information availability is improved, but usability deteriorates when user wants to execute different jobs
Solution Approach 1:
The system provides different information displays for different user needs: a filtered job list for users wanting to see authenticated jobs, or a shortcut key screen for users wanting to quickly execute different jobs. This localized quality approach ensures each user receives the most appropriate information display for their immediate needs
3Productivity
If confidential print jobs are executed without continuous authentication, then productivity is improved, but security protection deteriorates
Solution Approach 1:
The system implements periodic authentication during confidential job execution by monitoring user presence through the sensor. When the user moves away, authentication is temporarily suspended; when the user returns, authentication is restored. This periodic verification maintains security while allowing efficient job execution during authorized periods

AI summary
Disclosed is an image forming apparatus that prints a confidential image on a recording medium. The apparatus includes a display, a printer for printing images in a queue, an input for receiving identification information for a user, and a processor. The processor determines whether identification information from the input corresponds to reference identification information in a storage and enables the printer to print a confidential image if the identification information from the input corresponds to the reference identification information in the storage.
