Engineering Contradiction Analysis
1Speed
If digital platforms are used for data storage and transmission, then access to information becomes faster and easier, but authentication, protection, and traceability of data cannot be ensured
Solution Approach 1:
The patent introduces material elements (such as paper, plastic, or other physical substrates) as intermediary carriers that embed structural characteristics serving as digital signatures. These physical intermediaries provide authentication and protection capabilities that pure digital platforms lack, while still enabling fast digital access to the information they carry.
Solution Approach 2:
The patent combines digital information with physical material elements that have unique structural characteristics. This composite approach integrates the speed of digital platforms with the reliability of physical authentication, creating a hybrid system that achieves both fast access and secure verification through the embedded structural signatures.
2Reliability
If cryptographic algorithms are used to protect data, then data confidentiality is improved, but the protection relies on mathematical conjectures which may be vulnerable
Solution Approach 1:
The patent replaces mathematical/crypto-algorithmic protection mechanisms with physical structural characteristics of material elements. Instead of relying on complex mathematical conjectures, the system uses the inherent physical structure (fibers, grains, textures) of materials as the basis for authentication and protection, which are inherently secure and difficult to replicate.
Solution Approach 2:
The patent changes the fundamental parameter of security from mathematical complexity to physical structural uniqueness. By transitioning from algorithm-based security to material-structure-based security, the system achieves reliable protection without depending on the strength of mathematical conjectures, using instead the irreproducibility of physical material structures.
3Reliability
If material elements with complex structures are used to generate digital signatures, then data authentication reliability is improved, but the complexity of detecting and measuring these characteristics increases
Solution Approach 1:
The patent performs preliminary extraction and digitization of structural characteristics from material elements during the data creation or storage phase. By pre-processing and storing the digital representation of these structural features, the system avoids the need for complex real-time detection and measurement during authentication, thus maintaining high reliability while reducing operational complexity.
