Authentication Processing Method for Electronic Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in ensuring that private information is not shared with other users during certain application executions, necessitating effective authentication processing methods to manage credential information and network availability.
Innovation Solution
An authentication processing method and system for electronic devices that include a communication module, user interface, and processor, which transmit credential information to an external server, verify change enable/disable information, and determine whether to perform local or remote authentication based on network availability and credential changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device always transmits authentication requests to the external server through the communication module, then the authentication security is improved, but the network dependency increases and authentication may fail when network is unavailable
Solution Approach 1:
The authentication system is segmented into two independent parts: local authentication (using stored credential information in the electronic device) and remote authentication (using the external server). This segmentation allows the device to choose the appropriate authentication method based on network availability, resolving the contradiction between security and adaptability.
Solution Approach 2:
The credential information is preliminarily stored in the electronic device before network disconnection occurs. This preliminary action enables the device to perform local authentication even when the network becomes unavailable, ensuring both security and continuity of service.
2Adaptability or versatility
If the electronic device performs local authentication using stored credential information, then the network availability adaptability is improved, but the authentication security may be reduced if credential information is changed on the server
Solution Approach 1:
The system implements a feedback mechanism where the electronic device checks whether the credential information has been changed on the external server after performing local authentication. If a change is detected, the device updates its stored credential information. This feedback loop ensures that local authentication remains secure even when credential information is updated on the server.
3Reliability
If the electronic device checks for credential information changes on the external server, then the authentication security is improved, but the additional network communication increases time consumption
Solution Approach 1:
The system performs only a partial check for credential information changes - specifically checking whether the credential information has been modified, rather than performing complete re-authentication. This partial action approach maintains security while minimizing the additional time consumption associated with change detection.

AI summary
An electronic device and authentication processing method for operating the electronic device is provided. The authentication processing method includes transmitting to an external server credential information input in the electronic device through a user interface, receiving an authentication request of the credential information, processing the authentication request based on the credential information stored in the electronic device, or determining whether to transmit the authentication request through the communication module based on the credential information stored in the external server.
