QR Code Generation for Secure Wi-Fi Credential Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users often struggle to connect wireless devices to available Wi-Fi networks due to forgotten or unknown network login information, and there is a need for a secure method to provide authorized access without revealing confidential credentials.
Innovation Solution
The system generates a QR code representing Wi-Fi network credentials upon user request, allowing easy connectivity by scanning the QR code without exposing the actual login information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If network login information is displayed or shared directly, then ease of connection is improved, but security is worsened due to exposure of confidential credentials
Solution Approach 1:
The patent uses QR codes as an intermediary mechanism to transmit network credentials. Instead of directly displaying or sharing sensitive login information, the system generates QR codes that encode the credentials in a visually encoded format. This intermediary approach allows users to connect to Wi-Fi networks easily by scanning the code, while the actual credentials remain protected and are not exposed in plain text form.
2Ease of operation
If QR codes are generated and displayed, then ease of operation is improved, but device complexity is worsened
Solution Approach 1:
The patent creates visual copies (QR codes) of the network credentials rather than using the original sensitive data directly. The QR code serves as a copy that contains the same functional information (network login details) but in a different, more secure format. This copying approach simplifies the user interaction (scan to connect) while the underlying system complexity is managed through standardized QR code generation protocols.
Data Source
AI summary
Customers at a premises attempting to connect a new wireless device, such as a mobile phone or tablet to an available wireless network (Wi-Fi), receive network login information such as an Wi-Fi SSID (service set identification) and Password through a system generated equivalent QR code that can then be scanned to automatically connect to the Wi-Fi network. The system receives a request for Wi-Fi settings at a premises, identifies customer equipment associated with the premises, identifies an Wi-Fi SSID (Service Set Identification) and password associated with the customer equipment, generates a QR (Quick Response) code representing the Wi-Fi SSID and password, sends the QR code to one or more devices associated with the premises for display and subsequent scanning at the premises.
