Adaptive Authentication Screen Selection for MFPs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Multi Function Peripherals (MFPs) face challenges in user convenience due to the need for hardware modifications, such as fingerprint readers or IC card functionality, to facilitate secure authentication processes, which increase costs and complexity.
Innovation Solution
An information processing apparatus that determines the priority of authentication methods based on the type of operation device accessing it, using a combination of password and image authentication, and dynamically adjusts the authentication process based on the presence of a hardware keyboard and network connection, allowing for secure authentication without additional hardware requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint reader or IC card function is added to MFP for authentication, then authentication security is improved, but device cost and complexity increase
Solution Approach 1:
The MFP's existing display and operation interface are made multi-functional by enabling them to present authentication images and receive authentication inputs without requiring dedicated authentication hardware. The system universally uses the existing operational interface for both normal operations and authentication verification.
Solution Approach 2:
The system uses the MFP's own existing resources (display, processor, communication interfaces) to perform authentication functions without external dedicated hardware. The authentication process is self-contained within the MFP's existing operational framework.
2Reliability
If fingerprint reader or IC card function is added to MFP for authentication, then authentication security is improved, but device cost increases
Solution Approach 1:
The existing display and operation interface are made multi-functional by enabling them to present authentication images and receive authentication inputs without requiring dedicated authentication hardware. The system universally uses the existing operational interface for both normal operations and authentication verification.
Solution Approach 2:
The system replaces expensive dedicated authentication hardware with software-based authentication using existing components. The authentication function is implemented through software processing of images displayed on the existing screen, eliminating the need for costly fingerprint readers or IC card readers.
3Reliability
If password entry is required on MFP without hardware keyboard, then authentication security is maintained, but user convenience deteriorates
Solution Approach 1:
The mechanical keyboard input system is replaced with a visual authentication method using images displayed on the screen. Users authenticate by recognizing and selecting from displayed images rather than manually typing passwords, substituting mechanical key input with visual recognition and selection.
Solution Approach 2:
The authentication method changes from text-based password input to image-based visual recognition. The system presents authentication information in a different parameter form (visual images instead of text characters), making it more accessible to users without keyboards while maintaining security through image recognition.

AI summary
An information processing apparatus determines whether a device accesses a box region of the information processing apparatus. When it is determined that the box region is accessed, a box ID entry screen is displayed on the device. The information processing apparatus determines whether a box ID is entered by a user of the device. If it is determined that a box ID is entered, then device information about the device is obtained. After the device information is obtained, the information processing apparatus determines whether the device possesses a hardware keyboard. If it is determined that the device possesses a hardware keyboard, a password authentication screen is displayed on the device. If it is determined that the device does not possess a hardware keyboard, an image authentication screen is displayed on the device.
