Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for tracing digital information elements in computer systems, particularly those using blockchain-type distributed databases, are vulnerable to security breaches due to the increasing computing power of quantum computers, which can compromise the encryption of these elements.
Innovation Solution
A method that generates an identification element for digital information elements, signs it with a secure element associated with the user or device, and encrypts it using a cryptographic algorithm incorporating metric variables such as environmental, location, and biometric characteristics, storing the encrypted element in a blockchain-type distributed database and another database, ensuring secure, reliable, and trustworthy tracing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cryptographic algorithms are used to encrypt digital information elements in blockchain databases, then the security is sufficient for current computing capabilities, but the security becomes vulnerable when quantum computers with high computing power are deployed
Solution Approach 1:
The patent changes the parameters of the cryptographic system by incorporating multiple metric variables (environmental, location, biometric, time) into the cryptographic algorithm. This creates a dynamic encryption system where the cryptographic parameters are not static but change based on multiple measured variables, making the system resistant to quantum computing threats that rely on breaking fixed cryptographic algorithms.
Solution Approach 2:
The patent introduces dynamic elements into the cryptographic system by using real-time metric variables such as environmental characteristics, location data, biometric information, and time stamps. These dynamic parameters ensure that the encryption is continuously adapting, preventing static quantum algorithms from effectively breaking the security.
2Reliability
If multiple metric variables are incorporated into the cryptographic algorithm to enhance security, then the security against quantum threats is improved, but the complexity of the cryptographic system increases
Solution Approach 1:
The patent segments the cryptographic system into multiple independent metric variable measurements (environmental, location, biometric, time) that can be collected and processed separately. Each metric variable is obtained through dedicated sensors or systems, and they are then combined in the cryptographic algorithm, making the complexity manageable through modular organization.
Solution Approach 2:
The patent uses metric variables that can serve multiple functions: environmental data serves both as a security parameter and as context for the digital information, location data provides both security and identification, biometric data serves as both authentication and encryption key material. This multi-functionality reduces overall system complexity.
