Dual Tagging System for Secure Ownership Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for identifying articles and verifying ownership are ineffective in preventing counterfeits and copies, and they fail to securely transfer ownership, leading to increased costs and risks for manufacturers, resellers, and consumers.
Innovation Solution
A system comprising a first and second tagging device embedded in or attached to an article, with a central database that generates and pairs IDmaster and IDslave codes, ensuring secure ownership verification and transfer without storing sensitive information on the tagging devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a single tagging device with stored ownership information is used, then ownership verification is simplified, but the system becomes vulnerable to counterfeiting and information theft
Solution Approach 1:
The tagging system is divided into two separate tagging devices: a first tagging device embedded in the article containing identification information, and a second tagging device containing ownership information. This segmentation prevents single-point compromise and makes counterfeiting more difficult, as both tags must be replicated simultaneously to successfully counterfeit the article.
2Loss of time
If sensitive ownership information is stored on the tagging device, then ownership verification is faster, but the risk of information theft increases
Solution Approach 1:
A central database acts as an intermediary between the tagging devices and the ownership verification process. The database stores sensitive ownership information and communicates with the reading device to verify ownership without exposing sensitive data. This eliminates the need to store sensitive information on the tagging devices themselves, reducing theft risk while maintaining verification speed.
3Device complexity
If existing ownership verification systems are used, then implementation is simpler, but they fail to prevent fenced and stolen articles from being sold
Solution Approach 1:
The central database maintains a record of all articles and their ownership status, providing feedback to the system about whether an article is stolen or fenced. When an article is reported as stolen or fenced, the database updates its records and can immediately flag the article during verification processes, preventing its sale. This feedback mechanism enables real-time theft prevention without significantly increasing system complexity.

AI summary
A system for identifying an article (1) and whether there is an ownership of the article, the system comprising at least one article comprising a first tagging device (4) embedded in the at least one article and a second tagging device (5) embedded in or attached to the at least one article, at least one reading device (2), a central data processing device (3) comprising a storage device with a central database (15) stored thereon and a first transmitting/receiving device (8), and a second transmitting/receiving device (9), where the central database (15) at least comprises a virtual ID (19), the at least one virtual ID (19) comprising an owner profile, a public key, an identification master (IDmaster) code (13) and an identification slave (IDslave) code (14) being centrally generated and information regarding the article, where the first tagging device (4) comprises a tagging device ID (17), the public key and the IDmaster code (13) and is locked in a read-only mode, where the second tagging device (5) comprises a tagging device ID (18) and the IDslave code (14) and is locked in a read-only mode, and where the IDmaster code (13) and the IDslave code (14) are paired and locked to one another thus linking the ownership of the at least one article to the IDmaster code (13) and the IDslave code (14). A corresponding method as well as a method for transferring ownership of an article (1) is also provided.
