Conditional Notification for Secure Wi-Fi Easy Connect Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication apparatuses face challenges in improving the convenience of connecting to access points, particularly in establishing secure and efficient network setups without compromising user security and usability.
Innovation Solution
A communication apparatus configured to receive connection information from an information processing apparatus and execute predetermined processing to establish a connection with an access point, with conditional notification and input-based execution, utilizing protocols like Wi-Fi Easy Connect (WEC) and Device Provisioning Protocol (DPP) for secure network setup, and alternative methods for connection establishment when WEC fails.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the communication apparatus always outputs a notification to establish connection, then the ease of operation is improved, but the security is worsened due to potential unauthorized connections
Solution Approach 1:
The notification output condition is changed from always outputting to conditionally outputting based on whether connection information has been received. This parameter change resolves the contradiction by making the system notify only when appropriate, maintaining security while preserving ease of operation for legitimate connections.
2Productivity
If the communication apparatus automatically establishes connection upon receiving connection information, then the productivity is improved, but the security is worsened due to lack of user confirmation
Solution Approach 1:
A feedback mechanism is introduced where the system notifies the user before establishing a connection. The user's response (input or lack thereof) determines whether the connection proceeds. This feedback loop resolves the contradiction by maintaining high productivity through automatic processing while ensuring security through user confirmation.
Solution Approach 2:
The system performs a preliminary action (outputting notification) before the main action (establishing connection). This allows the user to review and confirm the connection request, ensuring security is not compromised while maintaining productivity through streamlined automatic processing upon confirmation.
3Reliability
If the communication apparatus waits for user input after notification, then the security is improved, but the loss of time is worsened due to delayed connection establishment
Solution Approach 1:
The system performs partial automation by notifying the user and waiting for input only when connection information is received, rather than always requiring user input or always connecting automatically. This partial action approach resolves the contradiction by balancing security (user confirmation) with time efficiency (automatic processing when no input is received).

AI summary
A communication apparatus includes an output unit configured to, in a case where a start condition of a predetermined state to receive connection information from the information processing apparatus is a first condition, output a predetermined notification, and in a case where the start condition of the predetermined state is a second condition different from the first condition, not output the predetermined notification, the connection information being intended to establish a connection between the communication apparatus and an access point outside the information processing apparatus and outside the communication apparatus, and a setting unit configured to, in a case where a first input is made in response to the predetermined notification, execute predetermined processing configured to establish the connection with the access point, and in a case where a second input is made in response to the predetermined notification, not execute the predetermined processing.
