Data Authentication Using Hash-Linked Physical Time Stamp Tokens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data processing units face challenges in securing data authenticity due to unauthorized access, as time stamps alone are insufficient to prevent data falsification and hacking, especially when data is stored in external databases unconnected to the Ethereum data structure.
Innovation Solution
A system utilizing a first and second data processing unit, with a converter and a high-accuracy cryogenic optical lattice clock to create a time stamp token integrating hash values and precise time data, which can be printed on physical media like stickers or notes, ensuring data uniqueness and non-fungibility through physical characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a time stamp is used to secure data authenticity, then data genuineness is improved, but vulnerability to unauthorized access and hacking increases
Solution Approach 1:
The patent transitions from purely digital time stamping to a hybrid physical-digital system by printing time stamp tokens on physical media (stickers, notes) with unique physical characteristics. This dimensional shift from digital-only to physical-digital hybrid space creates a new layer of security that cannot be accessed or replicated through digital hacking alone.
Solution Approach 2:
Physical media serves as an intermediary between the digital data and the authentication system. The printed time stamp token on physical media acts as a mediator that links the digital hash value and timestamp with unique physical characteristics (position, shape, texture), creating a bridge that prevents direct digital access while maintaining authentication functionality.
2Adaptability or versatility
If data is stored in external databases for NFT tokens, then adaptability and versatility are improved, but data security and genuineness deteriorate
Solution Approach 1:
The patent segments the authentication system into two independent parts: the digital NFT token stored in the Ethereum database and the physical time stamp token printed on separate physical media. This segmentation ensures that compromising one does not necessarily compromise the other, as the physical token contains the actual authentication data (hash value and timestamp) while the digital NFT only contains a pointer.
Solution Approach 2:
The patent creates a physical copy of the authentication data (time stamp token) that is independent of the digital storage system. This physical copy serves as the genuine authentication source, while the digital NFT is merely a reference or pointer to it, allowing the system to maintain NFT versatility while securing the actual data in the physical domain where hacking is more difficult.
3Ease of operation
If conventional clocks are used for time stamping, then ease of operation is improved, but measurement precision and authentication accuracy worsen
Solution Approach 1:
The patent changes the time measurement parameter from conventional clock precision to atomic clock precision (19 digits). This parameter change in time measurement accuracy creates a level of temporal resolution where the probability of two events occurring at the same timestamp becomes practically zero, providing near-absolute uniqueness to each time stamp while maintaining ease of operation through automated systems.
