Key Duplication Infrastructure With Authorized Remote Copying
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current key duplication methods require the original key, lack security in data storage and transmission, and do not ensure adequate access control, making it difficult for users to find convenient and secure duplication centers without the original key.
Innovation Solution
A method and infrastructure that allow key duplication without the original key, using detection means like cameras and CPUs to acquire characteristic parameters, which are then stored and used to generate authorization codes for secure duplication at designated centers, ensuring only legitimate users can access and duplicate keys.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If key duplication requires the original key to be present, then security is improved, but convenience and accessibility deteriorate
Solution Approach 1:
The system performs preliminary action by storing key characteristic parameters (geometric features, encryption data) in a centralized database before the duplication moment. When a user needs a key copy, the system retrieves pre-stored data instead of requiring the physical original key, thus improving convenience while maintaining security through controlled access to the database.
Solution Approach 2:
The patent introduces an intermediary system (centralized database with authorization server) that mediates between the original key and the duplication process. The database stores key parameters securely and provides authorized access to duplication centers, eliminating the need for physical key presence while maintaining security through authentication mechanisms.
2Ease of operation
If key duplication centers are distributed locally, then accessibility is improved, but reliability and security control deteriorate
Solution Approach 1:
The patent creates a universal system where multiple duplication centers connect to a single centralized database through standardized communication protocols. Each center can serve various key types and the system provides uniform security control across all locations, achieving both accessibility and reliable security management.
Solution Approach 2:
The centralized database acts as an intermediary that coordinates all distributed duplication centers. It authenticates users, verifies key parameters, and controls the duplication process remotely, ensuring consistent security standards across geographically dispersed centers while maintaining easy accessibility for users.
3Ease of operation
If key information is stored in centralized databases, then duplication convenience is improved, but data security and access control requirements increase
Solution Approach 1:
The patent segments the security system into distinct functional modules: user authentication module, key parameter verification module, authorization module, and duplication control module. This segmentation allows each component to handle specific security tasks independently, making the overall access control system more manageable and less complex while providing comprehensive security.
Solution Approach 2:
The system implements feedback mechanisms where the authorization server continuously monitors duplication requests, validates user credentials against stored key parameters, and provides real-time authorization decisions. This automated feedback loop ensures secure access control without requiring complex manual verification procedures, simplifying the user experience.

AI summary
A method of obtaining a copy key includes the steps of acquiring characteristic parameters of the original using a detection system; identifying operating instructions to reproduce the characteristic parameters so acquired; requiring authorization to load into a duplicating machine and/or use by a duplicating machine the operating instructions for creating the copy key; only if the authorization is given, loading the operating instructions into the duplicating machine and/or making the operating instruction available for use by the duplicating machine; controlling the duplicating machine so as to obtain, on the basis of the operating instructions previously loaded and/or made available, at least one copy key; and after the at least one copy key is obtained, removing the operating instructions from the duplicating machine.
