Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing document authentication methods require a processor or microchip in the document, making them costly and vulnerable to decryption by powerful computer systems like quantum computers, and lack mutual authentication between the document and the document reader.
Innovation Solution
An authentication document with a light guide structure, a light source, and a molecular layer that spectrally changes light, allowing for authentication of a document reader without a processor, using heterodyne light superimposition to create a unique light color for verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital encryption protocols (RSA, TLS) are used for authentication, then security is improved, but vulnerability to quantum decryption and processing costs increase
Solution Approach 1:
The patent replaces digital electronic encryption systems with an optical authentication system. Instead of using processors and digital protocols vulnerable to quantum decryption, the invention uses optical interference patterns generated by light passing through security features in the document. This substitution eliminates the need for complex digital processing while providing quantum-resistant security based on physical optical properties.
2Reliability
If a processor or microchip is included in the document for authentication, then authentication capability is improved, but production cost increases
Solution Approach 1:
The patent extracts the authentication functionality from electronic processors and microchips, relocating it to passive optical security features embedded in the document itself. The security features (such as holograms, optical variables, or interference patterns) inherently perform authentication through their optical properties without requiring active electronic components, thereby eliminating processor production costs.
Solution Approach 2:
The invention replaces expensive, complex electronic processors with inexpensive passive optical security features that can be manufactured using standard document production techniques. These optical features provide sufficient authentication capability without the high costs associated with embedding and programming microchips.
3Reliability
If conventional authentication methods are used, then document verification is improved, but mutual authentication between document and reader is not achieved
Solution Approach 1:
The patent implements mutual authentication through an interactive feedback mechanism. The document reader emits light that passes through the document's security features, and the resulting optical pattern is analyzed by the reader. Simultaneously, the document's optical response serves as feedback to verify the reader's authentication credentials. This bidirectional verification process enables both the document to authenticate the reader and the reader to authenticate the document.
