Wireless Connection Control Module for Proximity Data Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Close proximity wireless transfer technologies face security risks due to uncontrolled data exchange when a malicious third party brings an unregistered device close to a computer, potentially allowing data theft, as existing solutions like Jpn. Pat. Appin. KOKAI Publication No. 2007-18398 restrict communication to only registered devices but do not allow for necessary connections to unregistered devices.
Innovation Solution
An electronic apparatus with a communication module and connection control module that requires password verification for unregistered devices, adding the device to a connection permission list only if the entered password matches the registered password, thereby controlling and securing data exchange.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If close proximity wireless transfer permits data exchange unconditionally by touch operation, then ease of operation is improved, but security deteriorates due to potential data theft by malicious third parties
Solution Approach 1:
The patent applies preliminary action by pre-registering authorized devices in a connection permission list before actual data exchange occurs. When a device attempts to connect via touch operation, the system first checks whether the device is registered in advance. This preliminary registration mechanism allows the system to maintain ease of connection for authorized devices while preventing data theft from unregistered malicious devices, thus resolving the contradiction between operational convenience and security.
2Object-affected harmful factors
If close proximity wireless transfer uses pre-registration of devices, then security is improved, but adaptability deteriorates because unregistered devices cannot connect at all
Solution Approach 1:
The patent applies dynamics by making the connection permission list dynamically adjustable. The system allows users to add or remove devices from the registered list according to actual needs. When a user needs to connect a new authorized device, they can add it to the permission list; when a device should be blocked, it can be removed. This dynamic management capability enables the system to maintain security through pre-registration while adapting to changing connectivity requirements, thus resolving the contradiction between security and adaptability.
3Object-affected harmful factors
If close proximity wireless transfer requires password verification for unregistered devices, then security is improved, but ease of operation deteriorates due to additional authentication steps
Solution Approach 1:
The patent applies local quality by implementing different connection procedures for different device types. Registered devices享受 (enjoy) streamlined automatic connection without password verification, maintaining ease of operation. Unregistered devices that are not malicious (e.g., temporary or guest devices) can still connect by providing password verification, which prevents unauthorized access. This differentiated approach allows the system to maintain operational convenience for authorized devices while securing connections from unregistered devices, thus resolving the contradiction between security and ease of operation.

AI summary
According to one embodiment, an electronic apparatus comprises a communication module and a connection control module. The communication module is configured to execute close proximity wireless transfer. The connection control module is configured to start an operation of establishing a connection between the communication module and an external device which is in close proximity to the communication module if an identifier of the external device wirelessly transmitted from the external device is included in a connection permission list. The connection control module is configured to display a password entry screen if the identifier is not included in the connection permission list, and to add, if a password entered on the password entry screen matches with a registered password, the identifier to the connection permission list and start the operation of establishing the connection between the communication module and the external device.
