Particle-Embossed Surface Fingerprint for Object Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for authenticating and tracking objects in supply chains, such as blockchain-based solutions, often fail to provide a unique and secure identification of physical objects, as they can be easily copied or forged, and are not suitable for harsh environments.
Innovation Solution
A method involving patterning the surface of objects with an arrangement of hard particles to create a unique relief pattern, which serves as a physical fingerprint, that can be optically read and verified using existing devices like smartphones, and stored in a database for tracking and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain-based solutions are used for authentication and tracking, then visibility and trust along the supply chain are improved, but the identification of physical objects can still be easily copied or forged
Solution Approach 1:
The patent applies preliminary action by creating unique relief patterns on objects during the manufacturing process itself, before the objects enter the supply chain. These patterns are embossed directly onto the object surfaces using particle arrangements, establishing authentic identification features that cannot be added later without detection
Solution Approach 2:
The patent uses copying in reverse - instead of copying digital information to physical objects, it transfers physical particle arrangements into permanent relief patterns on object surfaces. The random positioning of particles creates unique patterns that are extremely difficult to replicate, as each particle's position becomes part of the object's permanent identity
2Reliability
If complex authentication tags are attached to objects, then unique identification is improved, but the manufacturing cost and complexity increase
Solution Approach 1:
The patent merges the authentication feature directly into the object's surface structure by embossing relief patterns during manufacturing. Instead of attaching separate authentication tags or labels, the unique identification becomes an integral part of the object itself, eliminating additional components and assembly steps
Solution Approach 2:
The patent changes the physical state and properties of the object surface by creating permanent relief patterns through embossing. The particle arrangements are transferred under pressure to form three-dimensional surface features that can be optically detected, transforming flat surfaces into uniquely patterned topographies
3Ease of operation
If existing optical detection methods are used, then detection simplicity is improved, but the ability to detect unique features for authentication is limited
Solution Approach 1:
The patent incorporates colorized particles into the relief patterns, adding optical contrast and visual differentiation to the embossed features. The color variations enhance the detectability of the unique patterns using standard optical cameras, as the colored particles create distinct visual signatures that are easier to capture and analyze

Function Achieved in This Case
This approach provides a secure, low-cost, and difficult-to-forgery physical fingerprint that can be easily detected, allowing for secure identification and tracking of objects throughout their lifecycle, resistant to counterfeiting and environmental harshness.
Implementation Method 1
a mechanical pressure is applied on the hard particles to transfer this amorphous pattern onto said surface and form a relief pattern for each object

AI summary
Technology for managing objects. A method is applied to a set of objects, for example, in view of commissioning such objects. The method includes patterning a surface of each object of a set of objects to be managed. The patterning is accomplished by using hard particles to make indentations in a surface of each object of the set of object, with the pattern formed on each object being a unique physical fingerprint that can be used to identify the object when performing various manage method(s) on the objects.
