Printing Apparatus Port Filter for Wireless Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printing apparatuses with direct wireless communication functions face security risks as they can be connected to unauthorized networks, allowing malicious access and data theft, as they do not have robust security measures to differentiate between permitted and unauthorized connections.
Innovation Solution
Implementing a port filter in the printing apparatus that can be set by users to enable or disable direct wireless communication, ensuring that only specific ports are used for direct wireless communication, while not affecting the wired LAN interface, thus enhancing security by restricting unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If direct wireless communication is enabled without restrictions, then ease of operation is improved, but security is worsened due to unauthorized access risks
Solution Approach 1:
The patent applies parameter changes by implementing a port filter that restricts wireless communication to specific port numbers. This allows the system to maintain ease of operation while improving security by changing the communication parameters (port numbers) that are permitted, thereby preventing unauthorized access without complicating the user interface.
2Object-affected harmful factors
If a port filter is implemented for direct wireless communication, then security is improved, but device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the communication interface into multiple ports and selectively enabling only specific ports for wireless communication. This segmentation approach improves security by isolating permitted communication channels while keeping the overall device architecture relatively simple and modular.
3Object-affected harmful factors
If port filter is applied to direct wireless communication, then security is improved, but adaptability is reduced
Solution Approach 1:
The patent applies dynamics by making the port filter configuration adjustable and adaptable. The system allows administrators to dynamically configure which ports are permitted for wireless communication, enabling the system to adapt to different security requirements and use cases while maintaining the security benefits of port filtering.
