Image Forming Apparatus Server-Mediated Wi-Fi Direct Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current image forming apparatuses using NFC for pairing and switching to Wi-Fi DIRECT as an access point are vulnerable to malicious access, as they freely share necessary information for authentication, allowing unauthorized users to connect.
Innovation Solution
Incorporating a notification unit for identifying the image forming apparatus, a requesting unit for security information from a server apparatus, and a switching unit that only activates Wi-Fi DIRECT communication after successful user authentication and receipt of security information from the server.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all information processing apparatuses brought close to the image forming apparatus are permitted to use wireless connection, then ease of operation is improved, but security is worsened allowing malicious access
Solution Approach 1:
The patent introduces a server apparatus as an intermediary that mediates between the image forming apparatus and information processing apparatuses. The server verifies authentication information and manages security credentials, acting as a trusted third party that enables convenient connection while preventing malicious access. The server apparatus receives authentication requests, verifies user credentials, and provides security information to authorized devices.
Solution Approach 2:
The patent implements preliminary authentication and security verification before allowing wireless connections. The server apparatus pre-verify user credentials and device authentication information before the image forming apparatus establishes a connection. This preliminary action ensures that only authorized users can connect, preventing malicious access while maintaining ease of operation for legitimate users.
2Object-affected harmful factors
If security verification through server apparatus is implemented, then security is improved, but device complexity is worsened
Solution Approach 1:
The patent segments the security verification function into a separate server apparatus, distinct from the image forming apparatus. This segmentation allows the image forming apparatus to maintain its core printing functions while delegating complex authentication and security management to a specialized server. The server apparatus handles credential verification, authentication management, and security information distribution, reducing the complexity burden on the image forming apparatus.

AI summary
An image forming apparatus includes a notification unit that notifies an information processing apparatus that is brought close to a specific portion of a body of the image forming apparatus about information for identifying the image forming apparatus and an access point name; a requesting unit that requests security information used for wireless connection using the image forming apparatus as an access point from a server apparatus that generates the security information on conditions that the security information has been requested by the image forming apparatus and user authentication concerning the information processing apparatus has succeeded; and a switching unit that switches to a communication mode using the image forming apparatus as an access point in a case where the security information is given by the server apparatus.
