Solution Overview

Problem

Current methods for authenticating manufactured diamonds are inadequate, as they rely on centralized databases that can be inaccessible due to network issues, and may allow for the creation of counterfeit diamonds by decoding gemstone characteristics.

Innovation Solution

A computerized certification system generates diamond reference characteristics and a visual code, which is written onto the diamond using a beam writing system, allowing for offline verification by comparing captured measurements with stored reference characteristics using a cryptographic hash function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If centralized databases are used for authentication, then authentication reliability is improved, but system accessibility deteriorates when network is unavailable

Engineering Contradiction:
Improveauthentication reliabilityVSAvoidsystem accessibility
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent extracts the authentication data from the centralized database and embeds it directly into the diamond as physical markings (laser inscriptions, holograms, or other permanent features). This allows the diamond to carry its own authentication information independently of any database, enabling offline verification while maintaining authentication reliability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent creates a physical copy of the authentication data by inscribing it directly onto the diamond surface. This physical inscription serves as a permanent, unchangeable record of the diamond's authentication status, eliminating the need for continuous database access while maintaining the ability to verify authenticity.

Inventive Principle:
Principle #26Copying

2Measurement precision

If database-based authentication is used, then authentication accuracy is improved, but vulnerability to counterfeiting increases

Engineering Contradiction:
Improveauthentication accuracyVSAvoidcounterfeiting vulnerability
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The diamond itself becomes the authentication carrier by having its physical characteristics (markings, inscriptions, holograms) directly inscribed on it. The diamond 'services' its own authentication by containing embedded information that cannot be altered or copied, making it self-verifying without requiring external database access.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent applies preliminary anti-action by inscribing authentication data directly into the diamond before any potential counterfeiting can occur. The physical markings and inscriptions are permanently embedded in the diamond's structure, making them impossible to replicate or alter, thus preventing counterfeiting attempts from the outset.

Inventive Principle:
Principle #9Preliminary anti-action

3Adaptability or versatility

If physical markings are inscribed on the diamond, then authentication independence is improved, but manufacturing complexity increases

Engineering Contradiction:
Improveauthentication independenceVSAvoidmanufacturing complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges the authentication function with the diamond's physical structure by inscribing markings, laser patterns, or holograms directly onto the diamond surface. This integration combines the gemstone with its authentication mechanism into a single unified object, eliminating the need for separate authentication tags or external database dependencies.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

A computerized system for determining the authenticity of a diamond comprises a computerized certification system and a computerized authentication system. The computerized certification system is configured to certify a diamond by generating diamond reference characteristics, using one or more physical characteristics of the diamond measured during a certification phase, and writing a visual code in or on the diamond, using a beam writing system. The computerized authentication system is configured to authenticate the diamond by generating diamond verification measurements, using one or more physical characteristics of the diamond, measured during an authentication phase, capturing the visual code of the diamond, and comparing the diamond verification measurements and the diamond reference characteristics, using the visual code captured from the diamond.
