Networked Image Processing Apparatus Login Status Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image processing apparatuses face usability issues due to insufficient authentication methods, particularly when IC cards are lost, leading to potential unauthorized access and unnecessary password input when logged in.
Innovation Solution
An image processing apparatus connected through a network, equipped with a processor and memory, includes a first acquisition unit for input information, a determination unit to assess login status, and a function control unit that requests authentication only when necessary, allowing authorized function execution without prompting for credentials when logged in.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication information input is always requested, then security is improved, but usability deteriorates due to unnecessary password input when logged in
Solution Approach 1:
The authentication request mechanism is made dynamic by adjusting its behavior based on the login status of the specific apparatus. The determination unit checks whether the apparatus is logged in, and the first request unit conditionally requests authentication information only when necessary (when not logged in). This dynamic adaptation resolves the contradiction by making the system secure when needed (improving reliability) while avoiding unnecessary authentication prompts when already authenticated (improving ease of operation).
2Reliability
If authentication is required for every function execution, then security is improved, but time efficiency deteriorates due to repeated password input
Solution Approach 1:
The system performs preliminary authentication by checking the login status of the specific apparatus before requesting authentication information. The determination unit assesses whether the apparatus is already logged in, and only the first request unit requests authentication information when the preliminary check indicates authentication is needed. This preliminary action prevents unnecessary authentication time loss while maintaining security requirements, resolving the contradiction between reliability and time efficiency.
3Reliability
If IC card-based authentication is used, then security is improved, but adaptability deteriorates when IC cards are lost or unavailable
Solution Approach 1:
The system introduces an intermediary login status check mechanism between the IC card authentication and function execution. The determination unit acts as an intermediary that checks whether the specific apparatus is logged in, allowing the system to accept alternative authentication methods or maintain authenticated state without requiring physical IC card presence. This intermediary mechanism improves adaptability while maintaining security, resolving the contradiction between reliability and adaptability.

AI summary
An image processing apparatus includes: a first acquisition unit acquiring input information from an outside for starting execution of an image processing function; a determination unit determining whether a specific apparatus connected through a network is logged in based on specific identification information corresponding to the input information; a first request unit requesting input of authentication information from the outside; and a function control unit controlling execution of the image processing function. When it is determined that the specific apparatus is not logged in, the first request unit requests the input of the authentication information from the outside. When it is determined that the specific apparatus is logged in, the function control unit permits the execution of the image processing function without the first request unit requesting the input of the authentication information from the outside.
