Fusion Splicer Lock Release via Server Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Fusion splicers used for optical fiber splicing lack effective security measures to prevent theft, as password-based locks can be deciphered, and existing distance-based locking methods render the device unusable if the paired terminal is lost, disrupting work operations.
Innovation Solution
A system comprising a fusion splicer, a server, and information terminals that use a communication network for locking and unlocking functions, where the server issues a one-time password considering date and time differences to authenticate and release locking, allowing continuous operation even when the paired terminal is lost or stolen.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a password-based lock mechanism is provided to prevent theft, then security against theft is improved, but the password can be deciphered and the device can still be stolen
Solution Approach 1:
The patent replaces traditional password-based mechanical locking with a remote locking system that uses communication networks and server-based authentication. The locking mechanism is no longer dependent on local password knowledge but on remote server verification, making password deciphering ineffective.
Solution Approach 2:
The patent introduces a server as an intermediary between the user and the fusion splicer locking mechanism. The server verifies authentication information and issues commands to lock or unlock the device remotely, creating a layer of security that prevents direct password access and deciphering.
2Reliability
If distance-based locking is implemented to prevent theft, then security against theft is improved, but the device becomes unusable if the paired terminal is lost, disrupting work operations
Solution Approach 1:
The patent implements a dynamic locking system where the locked state can be changed remotely based on authentication verification. When the paired terminal is lost, the user can authenticate through the server to dynamically change the locking state from locked to unlocked, maintaining device usability while preserving security.
Solution Approach 2:
The system provides feedback mechanisms where the server verifies authentication information and returns control commands to the user's terminal. This feedback loop allows the user to monitor the locking state and remotely adjust it based on the situation, ensuring both security and operational continuity.
3Reliability
If a one-time password system with date validation is used to enhance security, then authentication security is improved, but time zone differences cause authentication failures
Solution Approach 1:
The patent modifies the parameter validation approach by changing from strict date/time matching to flexible time zone accommodation. The server adjusts the validation parameters based on the user's location and time zone, allowing one-time passwords to work correctly across different time zones while maintaining security.
Solution Approach 2:
The system performs preliminary actions by having the server pre-configure time zone information and validation parameters before authentication occurs. The server proactively adjusts the authentication criteria based on the user's registered time zone, preventing authentication failures before they occur.

AI summary
A system for releasing locking of a fusion splicer includes a fusion splicer, an information terminal, and a server. The fusion splicer locks a fusion-splicing function in accordance with a predetermined lock condition and releases the locked function in accordance with a release command input. The server includes a storage unit that stores authentication information provided by a user of the fusion splicer, a collation unit that collates authentication information provided from the information terminal with the authentication information stored in the storage unit, and a password issuance unit that issues a one-time password including at least a date in an algorithm when a collation result is favorable. The information terminal authenticates the one-time password in consideration of a day difference or a time difference between the information terminal and the server and applies the release command to the fusion splicer when an authentication result is favorable.
