Endoscope Authentication via Dual Memory Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Single-use endoscopes remanufactured by inappropriate third parties can lead to defects due to inadequate cleaning, sterilization, or testing, posing a risk of fraudulent reuse.
Innovation Solution
An authentication method for endoscopes that includes a first memory storing first identification information and a second memory storing second identification information, with a processor comparing these to determine authenticity, preventing fraudulent reuse by prohibiting use if the information does not match.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If single-use endoscopes are remanufactured by third parties, then cost reduction and resource utilization are improved, but safety and reliability deteriorate due to inadequate cleaning, sterilization, or testing
Solution Approach 1:
The system performs preliminary authentication by comparing identification information from multiple memories before allowing the endoscope to be used. This preliminary check prevents fraudulent remanufactured endoscopes from entering the usage system, thereby maintaining safety while allowing legitimate remanufacturing.
Solution Approach 2:
The patent introduces an authentication system as an intermediary between the endoscope and its usage. This intermediary verifies the endoscope's authenticity by comparing ID information from different memories, acting as a gatekeeper that allows legitimate devices while blocking fraudulent ones.
2Reliability
If multiple memories with identification information are added to the endoscope, then authentication capability and fraud prevention are improved, but device complexity increases
Solution Approach 1:
The authentication system is segmented into multiple independent memories, each storing different types of identification information. This segmentation allows the system to verify authenticity through comparison without requiring a single complex authentication module, distributing the complexity across simple, independent storage units.
Data Source
AI summary
An authentication method for endoscope includes acquiring a first identification information stored in a first memory of the endoscope, acquiring a second identification information stored in a second memory of the endoscope, comparing the acquired first identification information with the acquired second identification information, and based on a result of the comparing, performing a first processing or a second processing.
