Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current bar codes and quick response codes are easily alterable, lack data protection, have low definition, and are difficult to read when soiled, and lack protection against copying, making them unsuitable for secure identification and authentication in various applications.
Innovation Solution
A security diffractive holographic code is created by embedding a conglomerate of DNA and nanoparticles with variable properties into a metalized foil, embossed with a high-definition QR or data-matrix code, and covered with a protective transparent layer, utilizing electron lithograph technology and a special pressing device to create a code that is difficult to replicate.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If standard printing methods are used for bar codes and quick response codes, then ease of manufacture is improved, but security against copying and alteration deteriorates
Solution Approach 1:
The code is formed by combining multiple materials with different properties: a metalized foil base layer providing structural integrity and reflectivity, synthetic DNA layers encoding the code information, and nanoparticle layers providing optical verification properties. This composite structure makes the code both manufacturable and secure against copying, as the specific combination and arrangement of materials cannot be easily replicated by standard printing methods.
Solution Approach 2:
The invention changes the physical and chemical parameters of the code from simple printed ink to materials with distinct measurable properties: the metalized foil provides specific reflectivity characteristics, the DNA layers provide molecular-level information storage, and the nanoparticles provide unique optical signatures. These parameter changes enable both manufacturing feasibility and security verification through specialized readers that detect these unique material properties.
2Ease of manufacture
If printed bar codes are used, then ease of manufacture is improved, but definition and readability deteriorate when soiled
Solution Approach 1:
The code is embedded within a metalized foil structure that acts as a flexible substrate, providing a durable base that resists degradation from soiling. The thin film structure of the DNA and nanoparticle layers deposited on this substrate maintains high definition even under adverse conditions, as the rigid foil base prevents warping or fading that would occur with printed ink.
3Reliability
If encrypted quick response codes are used, then security against copying is improved, but device complexity deteriorates
Solution Approach 1:
The invention replaces traditional electronic encryption methods with a physical-material-based security system. Instead of using software encryption algorithms that require complex processing, the security is embedded in the physical properties of the materials themselves: the specific arrangement of DNA sequences, the optical properties of nanoparticles, and the structural characteristics of the metalized foil. This substitution reduces device complexity while maintaining or enhancing security, as the verification can be performed through direct physical measurement rather than complex computational decryption.
