Motif-Integrated Surface Codes for High-Value Item Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for authenticating high-value items, such as coins and jewelry, fail to provide a secure and invisible marking that prevents counterfeiting and does not interfere with the item's appearance, while also allowing for additional information about the item to be easily accessible.
Innovation Solution
A quasi-invisible two-dimensional code is integrated into the item's surface, using line elements that slightly modify existing motifs, making it undetectable to the human eye but readable by a smartphone app, which links to a digital source for verification and additional information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a visible marking is applied to the item, then authentication information is provided, but the item's appearance is defaced
Solution Approach 1:
The patent applies a marking that is invisible to the human eye but detectable by UV light or specialized readers. This transforms the visual properties of the marking from visible to invisible under normal conditions, resolving the contradiction between providing authentication information and preserving the item's appearance.
Solution Approach 2:
The patent introduces an intermediary detection device (UV light source, smartphone app with camera) that mediates between the invisible marking and the user. The marking itself remains invisible, but the intermediary device reveals it when needed for authentication, thus preserving appearance while enabling verification.
2Shape
If an invisible marking under UV light is used, then the item appearance is preserved, but the marking can still be copied by counterfeiters
Solution Approach 1:
The patent changes the parameters of the marking system by using complex two-dimensional patterns with specific geometric relationships between elements. These patterns encode authentication data in a way that is difficult to replicate, transforming the marking from a simple visible indicator to a complex cryptographic-like structure that provides both invisibility and counterfeit protection.
Solution Approach 2:
The patent transitions from conventional one-dimensional or simple two-dimensional barcodes to complex two-dimensional patterns with multiple layers of information encoding. The marking includes specific geometric arrangements, spacing relationships, and pattern structures that add dimensional complexity, making copying difficult while maintaining visual invisibility.
3Loss of information
If a conventional barcode or QR code is applied, then information about the item can be provided, but the code can be read and copied easily
Solution Approach 1:
The patent transforms the simple linear or grid-based structure of conventional barcodes into complex two-dimensional patterns with specific geometric constraints. The marking includes elements with particular spacing, orientation, and arrangement rules that encode authentication information in a format that is readable by specialized apps but difficult to replicate without knowing the exact parameter specifications.
Solution Approach 2:
The patent divides the authentication marking into multiple discrete elements (lines, dots, shapes) arranged in specific two-dimensional patterns. Each element contributes to the overall authentication code, and the segmented structure with specific geometric relationships between elements makes copying more difficult compared to a continuous barcode structure.
4Reliability
If holograms are used for security, then authentication is provided, but the marking is easily visible and can be copied
Solution Approach 1:
The patent uses markings that are invisible under normal illumination conditions but become visible under specific conditions (UV light, specialized camera filtering). This transforms the visibility characteristic from constantly visible (like holograms) to conditionally visible, resolving the contradiction between security and invisibility by controlling the illumination state.
Data Source
AI summary
A method for authenticating a high-value item, wherein an optically identifiable code is generated and applied to the item by being integrated into a surface region of the item that is provided with graphics or a surface structure, wherein the code is read and interpreted using a reader, wherein the code is generated in the form of a two-dimensional arrangement comprising at least one of one or multiple dots, dash elements, line elements, the code elements having a shape comprising one of one or more multiple dots, dash elements, line elements forming part of the motif of the item, and wherein the code has information content decodable by a reader and is linked to an information source that provides information related to the item, and when the code is read by the reader, the link to the information source is activated and the information is displayed on the reader.
