Authenticity Verification Using Opaque Item Codes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for verifying the authenticity of packaged items are inadequate in preventing counterfeiting, as they do not sufficiently enhance detection, especially for items contained in packages.
Innovation Solution
A method and system that mark items with individual characteristics, generate and associate item and package authentication codes, and use image capture devices to verify authenticity by matching codes, either locally or remotely, with additional protection through database storage and excessive request tracking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional database lookup methods are used for authentication, then verification can be performed, but the system is vulnerable to counterfeiting and excessive requests
Solution Approach 1:
The authentication system is segmented into multiple independent components: opaque codes on packages, separate database storage, image capture devices, and request tracking mechanisms. This segmentation allows each component to perform its specific function independently, improving reliability while managing complexity through modular design.
Solution Approach 2:
The system performs preliminary actions by pre-generating unique opaque codes for each package during manufacturing and storing them in the database before authentication is needed. This preliminary preparation enables rapid verification during authentication without requiring complex real-time generation or allocation logic.
2Reliability
If multiple authentication codes are applied to each item, then counterfeit detection improves, but the manufacturing process becomes more complex
Solution Approach 1:
Instead of applying multiple physical authentication elements to each item, the system uses digital copying of authentication codes stored in a database. The same authentication code can be referenced multiple times without requiring multiple physical applications, simplifying the manufacturing process while maintaining detection capability.
Solution Approach 2:
The database serves as an intermediary that stores and manages authentication codes, eliminating the need to physically apply multiple codes during manufacturing. The intermediary handles the complexity of code management, allowing simple package construction while maintaining robust authentication.
3Ease of operation
If authentication codes are made visible, then verification is easier, but counterfeiters can replicate them more easily
Solution Approach 1:
The authentication code is designed with local quality characteristics - it is opaque and appears random or meaningless to humans, making it difficult to replicate or predict. The code's visual appearance provides no useful information to counterfeiters, while still serving its authentication function when processed by the verification system.
Solution Approach 2:
The system uses opaque codes that appear as random patterns or colors to human observers, making them visually unrecognizable and difficult to replicate. The visual complexity and opacity of the code provide inherent protection against counterfeiting while allowing machine or system-based verification.
4Measurement precision
If database lookup is performed for each verification, then authentication accuracy is maintained, but processing time increases
Solution Approach 1:
All authentication codes are pre-generated and stored in the database during manufacturing, eliminating the need for complex real-time calculations or lookups. The preliminary preparation of authentication data allows for rapid verification by simple comparison, maintaining accuracy while minimizing processing time.
Solution Approach 2:
The verification process uses simple copying and comparison of authentication codes between the package and database, rather than complex real-time computation. This copying approach maintains authentication accuracy through exact matching while significantly reducing processing time compared to generative or analytical methods.

AI summary
During manufacture and packaging of items whose authenticity is to be verified, the items are marked with individual item characteristics, and placed in a package. A first item authentication code is determined from the individual item characteristics of the marked items. A first package authentication code is generated, and the package is marked with the first package authentication code. During item authentication in the field, an image of the package and the marked items is captured, a second package authentication code and the individual item characteristics are extracted from the captured image, the extracted individual item characteristics are processed to generate a second item authentication code, and the authenticity of the marked items is verified by matching the first and second package authentication codes and by matching the first and second item authentication codes.
