Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional security features (holograms, optically variable inks) are used for product authentication, then counterfeiting resistance is improved, but device complexity and authentication reliability are worsened because these features can still be replicated by sophisticated counterfeiters
Solution Approach 1:
The patent replaces traditional mechanical/optical security features (holograms, variable inks) with a digital authentication system based on machine learning object recognition and blockchain technology. The system captures images of security features and processes them through ML algorithms to verify authenticity, substituting physical security mechanisms with computational verification methods that are harder to counterfeit.
Solution Approach 2:
The patent introduces an intermediary authentication system that acts as a mediator between the product and the verifier. Instead of directly relying on security features, the system uses ML-based object recognition as an intermediary layer that analyzes multiple characteristics and cross-references them against a blockchain database to determine authenticity, adding a layer of computational verification that enhances reliability.
2Reliability
If covert security features (UV-light detection, spectrometers) are used to detect authentication markers, then counterfeiting resistance is improved, but ease of operation is worsened because consumers require specialized equipment to verify authenticity
Solution Approach 1:
The patent makes the authentication system universal by enabling verification through standard mobile device cameras that most consumers already possess. The ML-based object recognition system is designed to work with common imaging devices rather than requiring specialized equipment, making the authentication process accessible to ordinary consumers while maintaining high counterfeiting resistance through sophisticated algorithmic analysis.
Solution Approach 2:
The patent creates a digital copy of the authentication process where the ML system analyzes images captured by standard cameras and compares them against digital templates stored on the blockchain. This copying approach allows verification using ubiquitous devices while maintaining security through computational methods, eliminating the need for consumers to purchase specialized detection equipment.
3Reliability
If physical unclonable functions (PUFs) are implemented in integrated circuits for authentication, then unclonability is improved, but manufacturing precision requirements are worsened due to the need for controlled random variations
Solution Approach 1:
The patent employs self-service mechanisms where the manufacturing process itself generates the security features through unavoidable random variations in material properties and microstructure. Rather than requiring precise control to create security features, the system leverages the inherent randomness of manufacturing processes, allowing the product to authenticate itself through its unique physical characteristics that naturally arise during production.
Solution Approach 2:
The patent changes the approach from controlling physical parameters precisely to embracing parameter variations. Instead of manufacturing identical security features, the system captures and analyzes variations in optical, electrical, or magnetic parameters that naturally occur during manufacturing. The ML algorithms are trained to recognize these unique parameter patterns, transforming manufacturing imprecision into a security advantage.

AI summary
A system and a method of receiving object data representing one or more discriminating characteristics of a physical object or group of physical objects is described herein. The method includes: processing the object data by means of a machine-learning-based object recognition process to obtain discriminating data representing one or more collision resistant virtual representations of the physical object or group of physical objects; comparing at least one of the discriminating data and an original hash value derived therefrom by application of a pre-determined cryptographic hash function thereto with corresponding reference data stored in one or more data repositories with restricted access; and, if said comparison with the reference data results in a match, outputting digitally signed identification data comprising said hash value.
