Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices may lack certain wireless protocol capabilities, such as Near-Field Communication (NFC), limiting their ability to securely transmit user information, and often do not have the necessary advanced processing or screen size for secure data exchanges, which are preferred for their security and usability.
Innovation Solution
A method and system where a computing device with NFC capabilities acts as a secondary device to facilitate secure data transmission by receiving a request from an electronic device, configuring the secure data exchange module, providing a user interface, receiving and transmitting user information, and confirming successful processing, enabling secure data transfer even if the electronic device lacks NFC capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If an electronic device lacks NFC capabilities, then device complexity is reduced, but secure data transmission capability is lost
Solution Approach 1:
The patent introduces a computing device as an intermediary that bridges the gap between NFC-capable devices and non-NFC devices. The computing device receives NFC data from one device and transmits it to another device lacking NFC capabilities, enabling secure data exchange without requiring both devices to have NFC hardware.
Solution Approach 2:
The computing device performs multiple functions: it acts as both an NFC host device and a data transmission intermediary. By supporting both NFC and alternative wireless protocols (such as Bluetooth or Wi-Fi), the computing device provides universal connectivity, allowing any electronic device to access secure data transmission capabilities through the computing device.
2Device complexity
If an electronic device lacks advanced processing capabilities, then device complexity is reduced, but usability for secure data exchange is limited
Solution Approach 1:
The computing device with advanced processing capabilities serves as a mediator that handles complex security operations. It performs encryption, decryption, and protocol translation, shielding non-advanced devices from technical complexity while providing full usability for secure data exchange through a simplified user interface.
Solution Approach 2:
The system enables non-advanced devices to perform secure data exchange autonomously by automatically establishing connections, authenticating devices, and managing data transmission through the computing device's secure data exchange module without requiring manual intervention or advanced user knowledge.
3Reliability
If NFC transmission distance is limited, then security is improved, but data exchange versatility is reduced
Solution Approach 1:
The patent segments the data exchange process into two distinct phases: a secure NFC phase for initial data transfer (maintaining security through limited transmission distance) and a versatile transmission phase using alternative protocols for data relay (enabling broader connectivity). This segmentation allows the system to leverage the security benefits of NFC while achieving greater versatility through protocol switching.
Solution Approach 2:
The computing device implements multi-functionality by supporting both NFC and alternative wireless protocols (Bluetooth, Wi-Fi). This allows the system to use NFC for secure initial exchange when devices are in close proximity, then switch to other protocols for extended-range communication, providing universal data exchange capability while maintaining security through the limited-range NFC channel.
