Lock System with Multifactor Authentication via Porosity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lock systems rely solely on key bitting for authentication, which can be easily perceived and duplicated, lacking an additional layer of security to prevent unauthorized access.
Innovation Solution
A multifactor authentication system that combines a first authentication structure using key bitting with a second authentication structure based on the variability of porosity characteristics of the lock actuating element, utilizing infrared radiation to detect and verify the porosity patterns, thereby enhancing security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional lock systems rely solely on key bitting for authentication, then the operation is simple and easy to use, but the security is insufficient and can be easily duplicated
Solution Approach 1:
The authentication system is divided into two independent segments: a first authentication structure that verifies key bitting and a second authentication structure that verifies porosity characteristics. This segmentation allows each structure to perform a specific authentication function, improving overall security while maintaining operational simplicity through modular design
Solution Approach 2:
The second authentication structure based on porosity characteristics is nested within the lock actuating element itself, similar to a nested doll. The porosity pattern is embedded in the material structure of the key, allowing the lock to verify both the external key bitting and the internal porosity characteristics without requiring separate physical components
2Reliability
If a second authentication structure based on porosity characteristics is added, then security is significantly increased, but the device complexity increases
Solution Approach 1:
The porosity characteristics of the lock actuating element serve as self-contained authentication data. The material's inherent porosity pattern automatically provides the second factor of authentication without requiring external databases, complex verification systems, or additional components beyond the basic lock mechanism
Solution Approach 2:
The patent replaces complex mechanical authentication systems with a combination of simple mechanical key bitting verification and optical/infrared detection of porosity characteristics. This substitution reduces mechanical complexity while enhancing security through the integration of non-mechanical detection methods
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system significantly increases security by making it difficult to duplicate the authenticating characteristics, providing an additional layer of authentication that is hard to perceive and replicate, thus preventing unauthorized operation of the lock assembly.
Implementation Method 1
utilizing infrared radiation to detect and verify the porosity patterns
Implementation Method 2
The degree of porosity of the material may vary between the subsections, such that the material of the first subsection permits the infrared radiation to pass through with a greater degree of intensity than the infrared radiation passes through the material of the second subsection

AI summary
A security system with multifactor authentication, and may comprise a lock assembly configured to secure an object and having a secured condition and an unsecured condition, a lock actuating element for actuating the lock assembly between the secured and unsecured conditions, a first authentication structure configured to permit actuation of the lock assembly by the lock actuating element when authenticated by the first authenticating structure, and a second authentication structure configured to permit actuation of the lock assembly by the lock actuating element when authenticated by the second authentication structure, so that authentication by the first authentication structure and the second authentication structure is required to actuate the lock assembly.
