Authentication Device for Point of Sale Goods Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for authenticating luxury goods are prone to forgery, difficult to verify, and lack systematic tracking, especially as they often require association with a single authentication medium, making them complex and inflexible.
Innovation Solution
A method and system that uses an authentication device not associated with the product but configured to receive information from a merchant terminal, obtaining a signed message, and providing authorization data if criteria are met, allowing flexible and secure authentication and tracking of goods using existing transaction infrastructure elements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a certificate is provided with the product to authenticate the good, then the authentication function is achieved, but the certificate can easily be forged and is difficult to verify
Solution Approach 1:
The patent replaces the mechanical certificate system with a digital authentication system using cryptographic signatures. The goods manager's private key signs authentication data, and the public key verifies it, eliminating physical certificates that can be forged while providing reliable digital verification through cryptographic methods.
Solution Approach 2:
The patent creates a digital copy of the authentication process where the goods manager's signing capability is replicated through cryptographic key pairs. Multiple authentication devices can be issued with the same public key, allowing verification without complex manual checks, thus reducing verification complexity while maintaining reliability.
2Reliability
If the authentication device is associated with the product before sale, then the product identity is tracked, but the system becomes complex and inflexible
Solution Approach 1:
The patent separates the authentication device from the product itself. The authentication device is a standalone entity that can be associated with different products at the point of sale through the merchant terminal, allowing flexible pairing without complex pre-association systems. This segmentation enables the same authentication device to serve multiple products while maintaining reliable tracking.
Solution Approach 2:
The patent implements a dynamic association mechanism where the authentication device links to the product at the moment of sale rather than being statically pre-associated. This dynamic approach allows the system to adapt to different sales scenarios and product types, enhancing flexibility while maintaining reliable tracking through the goods manager's verification process.
3Productivity
If certificates are filled in by the merchant at the point of sale, then the authentication information is recorded, but the process is error-prone and not systematic
Solution Approach 1:
The patent enables the merchant terminal to automatically generate and record authentication data without manual certificate filling. The system self-services by capturing product information and transaction details automatically, eliminating human error in data entry while maintaining high authentication efficiency through automated processes controlled by the goods manager's verification system.
Solution Approach 2:
The patent implements a feedback mechanism where the goods manager's system verifies authentication data automatically and provides authorization data back to the merchant terminal. This closed-loop feedback ensures data accuracy by validating information systematically rather than relying on manual certificate completion, improving both precision and efficiency.

AI summary
A method for a goods manager to authenticate products at the point of sale is provided. The method comprises: providing an authentication device to a merchant, wherein the authentication device is not associated with a product but is configured to receive product information from a merchant terminal; once information about a product has been received by the authentication device from the merchant terminal, obtaining from the authentication device a signed message comprising information about the authentication device and information about the product received from the merchant terminal; and providing authorization data to the authentication device if the information fulfils one or more criteria, thereby associating the authentication device with the product. A method for a merchant to authenticate goods at the point of sale and a merchant terminal to perform such a method are also provided.
