Curvilinear Code Embedding in 2D Patterns for Anti-Counterfeiting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating merchandise are vulnerable to counterfeiting as identifying markers can be detached and reused, making it difficult to ensure genuine products are differentiated from counterfeit ones.
Innovation Solution
Encoding information in 2-dimensional (2D) curves, such as QR codes, within a camouflage pattern, where the curves are embedded in a way that they are hidden from normal view but can be decoded through imaging techniques, ensuring the information is securely embedded within the merchandise.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional identifying markers (trademarks, bar codes, QR codes) are attached to merchandise for authentication, then product identification is enabled, but the markers can be detached and reused by counterfeiters, compromising authentication reliability
Solution Approach 1:
The patent embeds identifying markers within the internal structure of the merchandise packaging by creating cavities that contain the markers. The packaging structure itself becomes the container for the authentication element, making it integral to the product rather than a separate attachable component. This nesting approach prevents detachment and reuse by counterfeiters while maintaining authentication reliability.
Solution Approach 2:
The packaging structure is divided into multiple segments including outer packaging, inner packaging, and cavities that house the identifying markers. This segmentation allows the authentication marker to be integrated into specific portions of the packaging structure, making it difficult to remove or transfer to counterfeit products while preserving the overall packaging functionality.
2Reliability
If identifying markers are integrated into the merchandise structure to prevent detachment, then authentication reliability improves, but the manufacturing process becomes more complex
Solution Approach 1:
The identifying markers are incorporated into the packaging structure during the manufacturing process itself, rather than being added as a separate post-manufacturing step. Cavities for the markers are formed as part of the packaging fabrication, and the markers are placed within these cavities before final assembly. This preliminary integration simplifies the overall manufacturing workflow while ensuring the markers become an integral part of the packaging structure.

AI summary
A method of encrypting information includes converting an information sequence represented as a strings of bits into a curvilinear coding system, where each element of the curvilinear coding system corresponds to a sub-sequence of successive same-valued bits, converting said curvilinear coding system into a at least one closed curve, and embedding said at least one closed curve in a 2-dimensional pattern. A method for decrypting information includes extracting at least one closed curve from a digitized 2-dimensional pattern, and converting the at least one closed curve into an information sequence represented as a string of bits.
