Problem
Physical lock and key security systems are susceptible to theft and unauthorized access, and existing solutions that introduce digital authentication methods may be cumbersome, especially in high-security environments where electronics are not permitted.
Innovation Solution
A digital key management system that generates and verifies digital keys based on physical key structures, allowing secure sharing and updating of physical keys while maintaining compatibility with traditional lock and key systems, using a networked environment with computing devices, 3D printing, and security programs to manage and verify key access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital authentication methods are introduced to improve security, then security against theft and unauthorized access is improved, but the system becomes cumbersome and incompatible with environments where electronics are not permitted
Solution Approach 1:
The patent introduces a key management server as an intermediary that bridges traditional physical key systems and digital authentication. The server generates digital keys from physical key images, allowing electronic verification without requiring users to carry or manage complex digital authentication devices. This mediator enables secure verification while maintaining simplicity for end users.
Solution Approach 2:
The system creates a digital copy (image) of the physical key and uses this copy to generate verification data. Instead of requiring the original physical key for every authentication, the system works with replicated digital representations, enabling remote verification and key distribution without compromising the original key's security.
2Ease of operation
If physical keys are shared to improve accessibility, then ease of access is improved, but security against unauthorized access deteriorates
Solution Approach 1:
Instead of physically sharing the original key, the system generates and distributes digital copies (images) of the key to authorized users. These digital copies can be shared electronically without compromising the physical key's security. The key management server verifies each digital copy against the original, enabling secure sharing while maintaining access control.
Solution Approach 2:
The patent replaces the mechanical key-sharing system with a digital verification system. Instead of physically distributing keys and managing their security, the system uses electronic image processing and server-based verification to manage key access, eliminating the security risks associated with physical key distribution.
3Ease of operation
If traditional physical key systems are used to maintain simplicity, then ease of operation is improved, but vulnerability to theft and unauthorized access increases
Solution Approach 1:
The key management server acts as a mediator between the physical key and the locking system. It generates cryptographic verification data from the physical key's image, adding a layer of security without changing the user's interaction with the physical key. This intermediary layer prevents unauthorized access even if the physical key is stolen, as the server controls verification.
Solution Approach 2:
The patent introduces cryptographic verification mechanisms that replace or supplement traditional mechanical key verification. Instead of relying solely on the physical key's mechanical features, the system uses digital image processing and cryptographic algorithms to verify key authenticity, making the system resistant to theft and unauthorized duplication.
