Wireless Setup Terminal Using Feedback to Prevent Unauthorized Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network setup methods for electronic devices, such as smartphones and printers, risk connecting to low-security networks if connection information is transmitted unnecessarily, compromising device security.
Innovation Solution
A system where an information processing terminal, like a smartphone, obtains and determines whether to transmit connection information to another device only after verifying the existence of a first device that has completed setup, ensuring secure connection to a designated access point, and encrypts the information for secure transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection information is transmitted to enable easy setup of electronic devices, then ease of operation is improved, but security deteriorates due to risk of connecting to low-security wireless networks
Solution Approach 1:
The system implements feedback by having the information processing terminal receive setup completion status from electronic devices and use this information to determine whether to transmit connection information. The terminal determines whether setup is complete by receiving setup completion information from other electronic devices or by detecting whether the electronic device has connected to the wireless network, then uses this feedback to control subsequent transmission of connection information.
Solution Approach 2:
The system performs preliminary action by having electronic devices transmit setup completion information before the information processing terminal transmits connection information. The terminal waits to receive confirmation that setup is complete or that the device has connected to the network before proceeding with connection information transmission, ensuring security prerequisites are met first.
2Productivity
If connection information is transmitted without verification to all electronic devices, then productivity is improved by enabling quick setup, but harmful factors increase due to unauthorized access risks
Solution Approach 1:
The system applies local quality by transmitting connection information selectively to specific electronic devices based on their individual setup status rather than broadcasting to all devices uniformly. The information processing terminal determines on a per-device basis whether to transmit connection information by checking setup completion status for each device.
3Reliability
If the system waits for setup completion verification before transmitting connection information, then security is improved, but loss of time increases due to additional verification steps
Solution Approach 1:
The system implements self-service by having electronic devices automatically transmit their own setup completion information to the information processing terminal without requiring manual verification. The devices autonomously provide the necessary confirmation data, eliminating the need for user intervention in the verification process.

AI summary
According to an information transmission app, a CPU of an information processing terminal is configured to obtain connection information of an access point of wireless network and determine whether there exists an electronic device having completed the setup. When determining that there exists an electronic device having completed the setup, the CPU determines whether to transmit the connection information to an other electronic device. Further, when determining that there exists the first electronic device having completed the setup or when determining that the connection information is to be transmitted to the other electronic device, the CPU transmits the connection information to the other electronic device, and when determining that that the connection information is not to be transmitted, the CPU does not transmits the connection information. The other electronic device completes the setup using the connection information transmitted from the information processing terminal.
