Mobile Terminal One-Time Password Authentication for Remote Printer Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing sophistication of cyber attacks necessitates enhanced security measures for image forming apparatuses, particularly when accessed remotely via mobile terminals, as existing multi-factor authentication methods are inadequate for mobile access.
Innovation Solution
A mobile terminal generates a one-time password based on secret information managed by the image forming apparatus, transmitting it for authentication, and upon successful completion, allows operation of the apparatus, integrating with IC card and password authentication for robust security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-factor authentication using IC card and password is implemented for remote access, then security against cyber attacks is improved, but authentication complexity and user operation difficulty increase
Solution Approach 1:
The patent replaces manual IC card insertion and password typing with mobile terminal-based authentication. The mobile terminal automatically communicates with the image forming apparatus, transmitting authentication information without requiring physical card handling or manual keyboard input, thus substituting mechanical operations with automated electronic communication.
Solution Approach 2:
The authentication system enables self-service by allowing users to authenticate remotely using their mobile terminals. The mobile terminal automatically manages the authentication process, including transmitting the authentication code to the image forming apparatus, without requiring manual intervention for card insertion or password entry.
2Reliability
If one-time password authentication is implemented for PC terminal remote access, then security is improved, but the system cannot support mobile terminal access
Solution Approach 1:
The patent implements a universal authentication system that works across multiple terminal types. The image forming apparatus is configured to accept authentication requests from both PC terminals and mobile terminals using the same one-time password mechanism, enabling multi-functional support without requiring separate authentication systems for different device types.
Solution Approach 2:
The authentication system is designed to be dynamic and adaptable to different terminal types. The image forming apparatus can dynamically adjust its authentication interface and communication protocol based on whether the request comes from a PC terminal or a mobile terminal, while maintaining the core one-time password security mechanism.
3Ease of operation
If simple password authentication is used for remote UI access, then ease of operation is improved, but security against cyber attacks deteriorates
Solution Approach 1:
The system performs preliminary authentication actions by generating and transmitting a one-time password to the mobile terminal before the actual remote access operation. This preliminary step ensures that authentication credentials are securely established in advance, combining simple user interaction with strong security measures.
Solution Approach 2:
The mobile terminal acts as an intermediary between the user and the image forming apparatus. It securely transmits authentication information to the apparatus, providing a mediated authentication process that is both simple for the user (no manual password entry) and secure (one-time password mechanism).

AI summary
A mobile terminal that communicates with an image forming apparatus includes a generating unit configured to generate a one-time password based on secret information managed in association with the image forming apparatus, a transmission unit configured to transmit the one-time password generated by the generating unit and user information to the image forming apparatus, and a control unit configured to, upon successful completion of authentication processing based on the one-time password and the user information transmitted by the transmission unit, provide a service for operating the image forming apparatus.
