Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication codes are used, then the code can be printed on products, but the system is vulnerable to falsification and counterfeiting
Solution Approach 1:
The authentication code is segmented into multiple components: a visible human-readable portion and an invisible machine-readable portion (holographic matrix or laser micro-marking). This segmentation allows the code to serve dual purposes - aesthetic/display functions for humans and security verification for machines, thereby improving reliability without significantly increasing complexity
Solution Approach 2:
A holographic matrix or laser micro-marking system acts as an intermediary between the authentication code and the verification system. This intermediary encodes additional security information in a format that is difficult to replicate, enhancing authentication security while maintaining a simple user interface
2Adaptability or versatility
If digital rights management methods are applied, then software and multimedia works can be protected, but the methods are complex and not applicable to printed documents or molded items
Solution Approach 1:
The authentication system is designed with multi-functionality to work across different media types including printed documents, molded items, and digital materials. The core authentication mechanism remains consistent across applications, achieving versatility without proportionally increasing complexity
Solution Approach 2:
The system uses holographic matrices and laser micro-marking that can be replicated through legitimate manufacturing processes while being difficult to counterfeit. This allows wide application across different product types while maintaining security, achieving versatility without requiring complex custom solutions for each application
3Loss of information
If the authentication code contains extensive information, then comprehensive authentication is possible, but the code size becomes large and impractical
Solution Approach 1:
The authentication code structure embeds multiple layers of information: the visible human-readable code contains basic identification, while the invisible machine-readable portion (holographic matrix or laser micro-marking) contains nested security information and verification data. This nesting allows comprehensive authentication information to be contained within a compact overall code structure
Solution Approach 2:
The system transitions from a two-dimensional printed code to a three-dimensional holographic matrix or laser micro-marking structure. This dimensional change allows significantly more information to be encoded in a compact space, reducing the visible code size while maintaining information completeness through the additional spatial dimension

Implementation Method 1
marking said holographic matrix by laser shot, in order to produce a digital code that cannot be interpreted by the human eye, preserving the optical diffraction properties of the holographic matrix
Implementation Method 2
preserving the optical diffraction properties of the holographic matrix, and designed to enable the detection of a copy of a document realized using said holographic matrix
Data Source
AI summary
The authentication process comprises: a step of transferring a holographic matrix onto a base, a step of marking the holographic matrix by laser shot, in order to produce a digital code that cannot be interpreted by the human eye preserving the optical diffraction properties of the holographic matrix, and designed to enable the detection of a copy of a document realized using the holographic matrix. Preferentially, during the marking step, the impact of each laser shot presents a greater dimension and a depth allowing the hologram's optical diffraction properties to be preserved.
