Dynamic Authentication Control for Image Forming Apparatus Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses face challenges in enhancing security through user authentication, as current methods often rely on single-factor authentication, which can be vulnerable to unauthorized access.
Innovation Solution
A control method for an information processing apparatus that performs two-factor authentication by accepting first and second authentication information inputs, executing specific processing only upon successful authentication with both factors, and allowing execution of functions with successful authentication of at least one factor.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If single-factor authentication is used, then ease of operation is improved, but security is worsened
Solution Approach 1:
The system dynamically adjusts authentication requirements based on the function being accessed. For high-security functions, two-factor authentication is required; for standard functions, single-factor authentication suffices. This dynamic approach allows the system to adapt authentication strength to actual security needs, improving both security and ease of operation.
Solution Approach 2:
Different authentication methods are applied to different functions based on their security requirements. The system assigns appropriate authentication factors (knowledge-based, possession-based, or inherence-based) to specific functions, allowing each function to have the appropriate level of security without affecting overall system usability.
2Reliability
If two-factor authentication is implemented, then security is improved, but device complexity increases
Solution Approach 1:
The authentication system is segmented into distinct authentication factors (first authentication factor and second authentication factor) that can be independently selected and combined. This segmentation allows the system to manage complexity by organizing authentication methods into clear, manageable categories rather than treating them as a monolithic complex system.
Solution Approach 2:
The authentication framework is designed to be universal, supporting multiple types of authentication factors (knowledge-based, possession-based, inherence-based) that can be combined in various ways. This multi-functionality allows the same system to handle different authentication scenarios without requiring separate complex systems for each method.
3Reliability
If multiple authentication factors are required, then security is improved, but productivity decreases
Solution Approach 1:
The system dynamically determines the number and type of authentication factors required based on the function being accessed. High-security functions require two-factor authentication, while standard functions accept single-factor authentication. This dynamic approach prevents unnecessary authentication delays for low-risk operations while maintaining strong security for critical functions.
Solution Approach 2:
The system performs preliminary assessment of the function being accessed to determine authentication requirements before the user attempts to access it. This preliminary action allows the system to prepare appropriate authentication mechanisms in advance, reducing the time users spend on authentication by presenting the correct number of factors upfront rather than requiring multiple sequential authentication steps.

AI summary
A control method for an information processing apparatus controlled by a computer is executed by the computer and includes performing a first input to accept an input of first authentication information, performing a second input to accept an input of another authentication information different from the first authentication information, executing first processing on condition of success of authentication with the first authentication information input in the first input and success of authentication with the another authentication information input in the second input, and executing second processing on condition of success of at least one of authentication with the first authentication information input in the first input or authentication with the another authentication information input in the second input.
