Antitheft Apparatus for Prime Mover Equipment with Self-Updating Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing antitheft systems for equipment with prime movers require cumbersome updates to authentication ID information when electronic keys are lost or when the equipment is transferred to new owners, necessitating either a service technician's intervention or the equipment's return to the manufacturer.
Innovation Solution
An antitheft apparatus that includes an authenticator capable of updating authentication ID information based on the number of times the electronic key has been updated, allowing the system to verify and synchronize this information when a new key is introduced, enabling seamless transitions without requiring physical updates or technician involvement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If authentication ID information is updated using conventional methods, then security is maintained, but the update process becomes cumbersome and time-consuming
Solution Approach 1:
The system enables self-service by allowing the authenticator to automatically update authentication ID information when a valid electronic key with higher update counter is presented. The equipment itself performs the update without requiring external service technicians or specialized updating devices, thus maintaining security while dramatically simplifying the update process.
Solution Approach 2:
The electronic key stores update counter information in advance, which is compared against the authentication ID information during authentication. This preliminary preparation of update counter data in the key allows the system to determine whether an update is needed and perform it automatically, eliminating the need for cumbersome manual update procedures.
2Reliability
If authentication ID information is updated by service technicians or manufacturer, then security is ensured, but time and resources are wasted
Solution Approach 1:
The authenticator automatically performs the update of authentication ID information when presented with a valid electronic key that has a higher update counter. This eliminates the need for service technicians or manufacturer intervention, reducing update time to merely the time required for key presentation and authentication, while maintaining security through the established authentication protocol.
Solution Approach 2:
The update counter is pre-stored in the electronic key during key generation or previous updates. This preliminary action allows the system to immediately determine during authentication whether an update is needed and execute it on-the-spot, eliminating the time loss associated with scheduling service technician visits or shipping equipment to manufacturers.
3Object-affected harmful factors
If electronic keys are reissued with new ID information, then theft prevention is improved, but the synchronization of authentication information becomes complex
Solution Approach 1:
The system uses the update counter as a parameter to manage key reissuance and authentication information synchronization. When a key is reissued, its update counter is incremented. The authenticator compares this counter with the stored authentication ID information to determine whether synchronization is needed. This parameter-based approach simplifies the complexity by providing a clear, numerical criterion for update determination and execution.
Solution Approach 2:
The system implements feedback through the update counter comparison mechanism. The authenticator receives feedback from the electronic key's update counter, compares it with the stored authentication information, and automatically executes updates when the counter indicates a higher version. This feedback loop ensures automatic synchronization without complex manual procedures, maintaining theft prevention while reducing synchronization complexity.

AI summary
In an apparatus for preventing theft of equipment having a prime mover, an prime mover controller, and an authenticator that acquires ID information from an electronic key when the key is brought close thereto by an operator, and permits the prime mover controller to start the prime mover when the acquired ID information is determined to correspond with authentication ID information, data indicating a number of times the key is updated is included in the ID information, and the authenticator determines whether the number of times indicated in the data is greater than that in the authentication ID information, and when the number of times indicated in the data is greater than that in the authentication ID information, updates the authentication ID information such that it is equal to the number of times indicated in the data, thereby enabling to easily update authentication ID information of the equipment.
