Wearable Authentication Information Management via Server Sync
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for setting authentication information on wearable devices either burden users with operation inputs or compromise security due to fixed or simply inputted authentication information.
Innovation Solution
An authentication information management system that automatically receives and updates secure authentication information from an authentication server, using short-range communication and mobile communication to maintain user convenience and enhance security by regenerating authentication information as needed, detecting misuse, and ensuring proper transmission and association.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If authentication information is set through user input operation on terminal device, then user can control the authentication process, but operation burden increases and security level decreases
Solution Approach 1:
The terminal device automatically receives authentication information from the authentication server without requiring user input operations. The device performs self-service by autonomously managing the authentication information setup process, eliminating the need for manual user intervention while maintaining security through server-generated credentials.
Solution Approach 2:
The authentication server acts as an intermediary that generates and provides authentication information to the terminal device. This mediator approach allows the system to maintain security by having the server control the authentication information generation, while the terminal device automatically receives and uses it without direct user input.
2Ease of manufacture
If fixed authentication information is preset for wearable device, then setup process is simplified, but security level decreases due to fixed credentials
Solution Approach 1:
The authentication information is made dynamic by allowing automatic updates from the authentication server. Instead of using fixed preset credentials, the terminal device periodically receives updated authentication information, transforming the static security model into a dynamic one that maintains security while simplifying initial setup.
Solution Approach 2:
The authentication server performs preliminary action by generating authentication information in advance and providing it to the terminal device automatically. This eliminates the need for manual presetting while ensuring security credentials are established before actual authentication is needed.
3Ease of operation
If authentication information is automatically received from authentication server, then operation burden is reduced, but system complexity increases
Solution Approach 1:
The terminal device leverages its existing communication capabilities to perform multiple functions - it uses its network communication interface not only for general data transmission but also for receiving authentication information from the authentication server. This multi-functionality approach avoids adding dedicated hardware complexity while enabling automatic authentication information management.

AI summary
An objective is to provide a terminal device, an authentication information management method, and an authentication information management system for securing a security level of authentication information while maintaining the convenience for a user. A mobile device (10) determines whether communication with a wearable device (30) is possible and determines whether the mobile device (10) is able to communicate with an authentication server (20). When it is determined that communication between the mobile device (10) and the wearable device (30) is possible and communication between the mobile device (10) and the authentication server (20) is possible, the mobile device (10) transmits identification information corresponding to the wearable device (30) to the authentication server (20), requests the authentication server (20) to transmit authentication information, receives the authentication information from the authentication server (20) in response to the transmission request, and transmits the received authentication information to the wearable device (30).
