Authentication Control for Image Forming Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image forming systems, users face inconvenience and security risks due to the need for user authentication at the image forming device, especially when the information processing device and image forming device are close or when unauthorized individuals are nearby, leading to unnecessary authentication steps and potential security breaches.
Innovation Solution
An image forming device terminal that automatically determines whether to perform user authentication based on conditions for each printout job, allowing for 'authentication print' or normal print processes, ensuring security and convenience by switching between these modes based on job data and user authentication results.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If user authentication is always required at the image forming device, then information security is improved, but user operability and convenience deteriorate due to unnecessary authentication steps
Solution Approach 1:
The patent applies dynamics by making the authentication requirement flexible rather than fixed. The image forming device dynamically adjusts whether to require authentication based on real-time conditions such as user presence detection, job priority levels, and security sensitivity. This allows the system to transition between secure and convenient modes automatically, resolving the contradiction between always maintaining security and allowing ease of operation when security risks are low.
Solution Approach 2:
The patent changes the parameter of authentication requirement from a binary constant (always required/never required) to a variable parameter that can be adjusted based on multiple factors including user presence, job importance, and detected security risks. This parameter change enables the system to optimize both security and operability by adapting the authentication requirement level to match the actual situation.
2Reliability
If user authentication is always required, then security against unauthorized access is improved, but productivity deteriorates due to additional authentication time
Solution Approach 1:
The system dynamically adjusts authentication requirements based on real-time assessments of security risks and user contexts. When the system determines that security risks are low (e.g., user presence confirmed, low-priority jobs), it automatically reduces or eliminates authentication steps, thereby maintaining security when needed while eliminating unnecessary authentication delays that reduce productivity.
Solution Approach 2:
The patent implements preliminary action by performing user presence detection and security risk assessment before the authentication step. By detecting user presence through sensors or other means prior to requesting authentication, the system can pre-determine whether authentication is actually necessary, avoiding the productivity loss associated with redundant authentication requests for jobs that don't require security measures.
3Reliability
If authentication is requested for all print jobs, then information security is improved, but device complexity increases due to authentication management
Solution Approach 1:
The patent applies segmentation by dividing the authentication management into different levels and categories. Instead of a single unified authentication system for all jobs, the device segments authentication requirements based on job priority, user roles, document sensitivity, and detected security conditions. This segmentation allows the complex authentication logic to be organized into manageable modules that can be independently controlled and optimized.
Solution Approach 2:
The system implements self-service by automatically managing authentication requirements without requiring user configuration or administrator intervention for each job. The image forming device autonomously assesses security risks, detects user presence, and determines authentication requirements based on pre-configured policies and real-time conditions, thereby reducing the operational complexity of managing authentication while maintaining high security standards.

AI summary
The present invention provides an image forming device terminal for enhancing the productivity of the image forming process such as printing. An image forming device terminal for instructing execution of a printout process on an image forming device capable of executing an authentication print printing, includes a selection accepting unit which accepts a selection of an image forming device for executing the printout process from a plurality of image forming devices; a determination unit which classifies the selected image forming device to a first type image forming device or a second type image forming device based on whether or not the selected image forming device is a default set image forming device; and a generating unit which generates job data as a printout process of not the authentication print printing in a case where the selected image forming device is the first type image forming device, and generates job data as a printout process of the authentication print printing in a case where the image forming device is the second type image forming device.
