Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional image analysis methods are used for authentication, then the process is simple and accessible, but the reliability and statistical surety are insufficient
Solution Approach 1:
The patent transitions from traditional 2D visible light imaging to multi-spectral and hyperspectral imaging, adding spectral dimensions to the analysis. This enables detection of features across multiple wavelength ranges (UV, visible, infrared) that are invisible to the human eye, thereby significantly improving authentication reliability while managing complexity through systematic data processing approaches
Solution Approach 2:
The system changes the parameters of light interaction with the artwork by analyzing reflectance, transmittance, and fluorescence properties across multiple spectral bands. This enables detection of subsurface features, pigment composition, and structural characteristics that provide statistically reliable authentication data
2Reliability
If noninvasive hyperspectral and multi-spectral techniques are used, then authentication reliability improves, but the complexity of the system increases
Solution Approach 1:
The imaging system is divided into multiple specialized modules, each handling specific spectral ranges (UV, visible, infrared) and detection modes (reflectance, transmittance, fluorescence). This segmentation allows for optimized performance in each domain while managing overall system complexity through modular architecture
Solution Approach 2:
The system integrates multiple imaging modalities and spectral ranges into a unified platform that can perform various authentication functions (pigment analysis, subsurface feature detection, material identification) using a single multi-spectral/hyperspectral system, reducing the need for multiple separate devices
3Measurement precision
If multiple electromagnetic spectrum bands are analyzed, then the unique digital fingerprint accuracy improves, but the data processing complexity increases
Solution Approach 1:
The system performs preliminary processing of multi-spectral data by organizing it into structured formats that capture key features across different spectral bands before final authentication comparison. This preliminary structuring simplifies subsequent analysis and reduces the computational burden of comparing complex spectral datasets
Solution Approach 2:
The system creates simplified digital representations (fingerprints) that copy and encode the essential spectral characteristics of the artwork into a compact format. This copying process transforms complex multi-dimensional spectral data into manageable fingerprint identifiers that can be efficiently stored and compared while retaining authentication precision

AI summary
Disclosed are systems, devices and methods for quantifying unique features of an object such as an artistic work to identify and authenticate the object and specific characteristics thereof using multi- spectral diagnostic characterization techniques and analytical algorithms. In some aspects, a method for creating an identification for an object includes acquiring image data of an object in two or more electromagnetic spectrums along a coordinated array of sample regions of the object; analyzing the acquired image data to produce a quantitative data set including specific characteristics of the object associated with the two or more electromagnetic spectrums for each sample region; generating a digital identification associated with a unique data fingerprint, based on the specific characteristics, in which the digital identification solely corresponds to the object; and storing the generated digital identification.
