Dynamic Security Element Triggering for Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems are vulnerable to unauthorized access due to their reliance on static security features that can be easily copied or intercepted, and they lack dynamic elements to enhance security.
Innovation Solution
An authentication system utilizing dynamically changing security features, such as a surface, structure, or composition that can be detected and transmitted for evaluation, with inherent or external triggers causing changes that are stored and compared for authentication purposes, providing a secure and unpredictable security mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If static security features (PIN, password, biometric data) are used for authentication, then the authentication system is simple to implement and operate, but the security is vulnerable to copying, interception, and circumvention
Solution Approach 1:
The patent applies the dynamics principle by transforming static security features into dynamic ones. The security element's appearance changes over time due to inherent triggers (chemical reactions, physical changes) or external triggers (light irradiation, temperature changes). This dynamic transformation ensures that the security feature is never identical at two different points in time, making it uncopyable and resistant to interception attacks while maintaining system reliability.
Solution Approach 2:
The patent employs parameter changes by modifying physical or chemical parameters of the security element to create dynamic security features. Examples include changing the refractive index through chemical reactions, altering luminescence properties through light irradiation, or modifying surface topology through phase transitions. These parameter changes enable the security feature to evolve over time, enhancing security without requiring complex system architecture.
2Ease of operation
If biometric detection methods (fingerprint, iris scan) are used, then user identification is convenient and contactless, but the biometric data can be copied and does not change, making it vulnerable to attacks
Solution Approach 1:
The patent resolves this contradiction by making the security feature dynamic while maintaining ease of operation. The security element's appearance automatically changes over time due to inherent triggers such as chemical reactions or physical changes, ensuring that even if biometric data is captured, it becomes obsolete quickly. The system remains contactless and convenient for users while the dynamic nature of the security feature prevents copying attacks.
3Stability of the object's composition
If predetermined structures (3-D codes, bar codes) are used for security features, then the information encoding is reliable and stable, but the structure does not change and can be easily circumvented by attackers
Solution Approach 1:
The patent applies dynamics by transforming predetermined static structures into dynamic structures that change over time. The security element's appearance evolves through inherent or external triggers, ensuring that the structure is never identical at two different points in time. This maintains the stability needed for reliable information encoding while preventing circumvention attacks, as attackers cannot obtain a valid structure to replicate.
Solution Approach 2:
The patent introduces an intermediary element - the trigger mechanism (chemical, physical, or external) - that mediates between the stable information encoding requirement and the need for dynamic change. The trigger causes the security feature to transform while preserving the encoded information's integrity, allowing the system to meet both stability and security requirements simultaneously.
4Reliability
If security features are stored separately from the application server in autonomous authentication devices, then centralization is reduced and security is improved, but the security features remain inflexible and can be copied
Solution Approach 1:
The patent applies dynamics by enabling the security element to change its appearance over time through inherent or external triggers. This dynamic capability provides flexibility to distributed authentication devices, allowing them to adapt to different authentication scenarios while maintaining security. The security feature can transform to prevent copying and circumvention attacks, enhancing both security and adaptability in decentralized systems.

Function Achieved in This Case
The system significantly increases security by ensuring that the dynamic changes in the security features are unpredictable and uncopyable, making unauthorized access more difficult, thus enhancing the authentication process for persons, objects, and data-based media.
Implementation Method 1
The triggering means, which preferably itself is dynamic, causes a change in the security features
Implementation Method 2
