Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If spectral signature methods are used for authentication, then authentication capability is improved, but applicability is limited to scenarios where spectral signatures are practical and reliable
Solution Approach 1:
The patent transitions from spectral signature parameters to spatial orientation parameters. By measuring the orientation of crystalline particles (e.g., diamond with nitrogen-vacancy centers) in three-dimensional space, the system creates authentication markers that work across diverse scenarios including field deployments where spectral methods fail. The unique spatial distribution and orientation of particles provide a new parameter space for authentication that is both reliable and broadly applicable.
2Reliability
If complex cryptography protocols are used for security, then security level is improved, but device complexity and operational efficiency deteriorate
Solution Approach 1:
The patent creates self-service authentication through physically unclonable functions embedded in the object itself. The unique spatial orientation of crystalline particles within an object serves as an inherent authentication marker that requires no external cryptographic infrastructure. The object's physical structure itself becomes the security mechanism, eliminating the need for complex cryptographic protocols while maintaining high security levels.
Solution Approach 2:
The patent replaces complex cryptographic software systems with a physical measurement system based on magnetic resonance and fluorescence detection of particle orientations. Instead of relying on computational cryptography, the system uses physical properties of crystalline particles (nitrogen-vacancy centers in diamond) that can be measured to generate unique authentication codes, significantly reducing device complexity.
3Reliability
If traditional anti-counterfeit techniques are used, then authentication capability is improved, but unclonability and efficiency deteriorate due to lack of unique physical property utilization
Solution Approach 1:
The patent performs preliminary action by embedding unique spatial orientation information into objects during manufacturing. The crystalline particles are positioned and oriented in specific three-dimensional configurations that serve as pre-established authentication markers. This preliminary encoding of unique physical properties enables rapid authentication later without requiring complex real-time analysis, significantly improving authentication efficiency.
Solution Approach 2:
The patent shifts from using chemical composition parameters (traditional anti-counterfeit) to spatial orientation parameters. By measuring the precise three-dimensional orientations of crystalline particles, the system creates unique authentication signatures that are inherently unclonable. This parameter change enables both high authentication capability and rapid verification, as the spatial configuration can be quickly measured and compared against stored reference data.

AI summary
In a general aspect, orientation information is used to generate a unique code. In some aspects, orientation information is extracted from an object. The object includes multiple elements, and the orientation information indicates the relative spatial orientations of the respective elements. The orientation information can be extracted, for instance, by a scanner system that detects the elements. A unique code is generated for the object based on the orientation information. In some examples, the elements are diamond particles that each have one or more color centers, and the orientation information is extracted by detecting the color centers.
