QR Code Wireless Network Connection Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network connection setting methods are complex and lack security, as they often require manual input of sensitive information like SSIDs and passwords, making them vulnerable to misconfiguration and unauthorized access.
Innovation Solution
A wireless communication system that uses a digital camera and portable terminal to encode and decode QR code images containing wireless network connection setting information, allowing secure and simplified connection to a wireless network by generating and transmitting SSIDs and passwords based on predetermined conversion rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual input of wireless network connection setting information is used, then the connection process is simple, but security is poor and misconfiguration is vulnerable
Solution Approach 1:
The patent uses barcode technology to create a visual copy of the wireless network connection setting information. Instead of manually inputting SSID and password, the settings are encoded into a barcode image that can be captured and decoded by another device, eliminating manual input while maintaining security through the encoded format.
Solution Approach 2:
The patent introduces a barcode as an intermediary carrier between the network settings source and the target device. The connection settings are transformed into a visual barcode format that serves as a secure medium for transferring information without direct manual input or exposure of sensitive data.
2Reliability
If barcode encoding of network settings is used, then security is enhanced, but the system complexity increases
Solution Approach 1:
The patent leverages existing barcode technology and imaging capabilities that are already widely available in smartphones and other portable devices. By using a universal barcode format rather than a proprietary encoding system, the solution maintains security enhancements without requiring specialized hardware or complex custom decoding algorithms.
3Speed
If conversion rules are stored locally in each device, then connection speed is fast, but adaptability to different networks is reduced
Solution Approach 1:
The patent stores conversion rules in a structured format that allows flexible interpretation for different network types. The conversion rules can be adjusted to accommodate various wireless network standards and configurations, enabling the system to adapt to different networks while maintaining efficient local processing for quick connection establishment.
Data Source
AI summary
A generation unit generates the wireless network connection setting information from the first information based on the conversion rule. The encoding unit encodes the first information to generate a code image. A display unit displays the code image. An imaging unit captures the code image. A decoding unit decodes the code image captured by the imaging unit and acquires the first information. A second storage unit stores a conversion rule that is the same as the conversion rule stored in the storage unit. A second generation unit generates the wireless network connection setting information from the first information acquired by the decoding unit based on the conversion rule stored in the second storage unit. A communication unit connects to a wireless network using the wireless network connection setting information generated by the second generation unit.
