Solution Overview

Problem

Existing methods for authenticating branded products are not sufficiently secure, as they do not reliably distinguish originals from counterfeits, as they can be easily copied or queried by intermediaries, and rely on complex codes or labels that can be forged.

Innovation Solution

Utilizing banknotes with unique serial numbers as data carriers, attached to products or their packaging, and maintaining a publicly accessible database to verify the authenticity of these serial numbers, which are protected against unauthorized access, allowing customers to confirm the product's originality by querying the database.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a code is applied to the product or its packaging for authentication, then the product can be identified individually, but the code can be easily copied or forged by counterfeits

Engineering Contradiction:
Improveauthentication securityVSAvoidsecurity mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies a universal authentication mechanism using banknote serial numbers that can be used across different products and regions. The banknote serial number system serves multiple functions: it provides unique identification, inherent security through central bank issuance, and database verification capability, eliminating the need for product-specific complex security features

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent utilizes banknotes as disposable authentication carriers attached to products. Each banknote with its unique serial number serves as a single-use authentication element that can be verified once and then discarded or removed, preventing reuse by counterfeits while maintaining low cost

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

2Ease of operation

If a database is made publicly accessible for verification, then customers can authenticate products easily, but intermediaries can query and potentially misuse the codes

Engineering Contradiction:
Improveauthentication accessibilityVSAvoidunauthorized access and misuse
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent implements a feedback mechanism where the database not only stores banknote serial numbers but also tracks verification status. When a serial number is queried, the system provides feedback on whether it has been verified before, allowing customers to detect potential counterfeits while enabling the system to identify and prevent unauthorized bulk querying by intermediaries

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent introduces the banknote serial number as an intermediary element between the product and the authentication system. The banknote acts as a trusted mediator issued by central banks, whose serial numbers are inherently secure and can be verified through the database without exposing sensitive product information or authentication logic

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If complex security mechanisms are used to prevent forgery, then authentication reliability improves, but the system becomes more complicated and costly

Engineering Contradiction:
Improveanti-forgery capabilityVSAvoidsecurity system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent reverses the traditional approach by not trying to prevent copying of the authentication element itself, but rather by using a copying-resistant identifier (banknote serial number) that is inherently difficult to forge. The banknote serial number system leverages the existing security infrastructure of central banks rather than creating new security mechanisms

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent changes the fundamental parameter of authentication from product-specific codes to universal banknote serial numbers. This parameter change leverages the inherent security properties of currency systems, including centralized issuance, unique serial number generation, and widespread recognition, thereby achieving high security with minimal complexity

Inventive Principle:
Principle #35Parameter changes

AI summary

The invention relates to a method for authenticating an individual product from a series, to which at least one specific code is assigned on a data carrier. This code is stored in a publicly accessible database, read by a third party and entered into the database, and based on a comparison of the entered code with the codes of all products in the series stored in the database, the database generates an output indicating whether the code is identical to a stored code and/or has already been queried previously. Known methods of this kind are not sufficiently secure, complex, and expensive. The problem of further developing an authentication method so that originals can be distinguished from counterfeits with the highest possible certainty is solved by using an official banknote of a national central bank as the data carrier and the code as its official serial number.The invention further relates to a corresponding product and the use of a banknote in accordance with the described method.
