Portable Device Authentication Protocol for Product Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current product authentication methods are inadequate due to reliance on proprietary technologies, high costs, limited availability, and vulnerability to counterfeiting, especially in international supply chains, where consumers struggle to verify product authenticity without specialized devices or complex procedures.
Innovation Solution
A cryptographic-based authentication protocol using portable devices to generate and verify product identification numbers (PINs) with open and hidden parts, allowing for real-time, cost-effective authentication without requiring special sensors or software, and providing incentives for consumers to use genuine products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If proprietary authentication technologies are used, then authentication reliability is improved, but device cost and complexity increase
Solution Approach 1:
The authentication system is segmented into two parts: a secure server-side component that maintains the authentication database and cryptographic keys, and a simple client-side component (portable device) that only needs to capture images and communicate with the server. This segmentation allows high reliability through secure server-side verification while keeping the client device simple and inexpensive.
Solution Approach 2:
A centralized authentication server acts as an intermediary between the portable authentication devices and the product database. The server handles complex verification operations, cryptographic operations, and database queries, allowing portable devices to remain simple while maintaining high authentication reliability through server-side processing.
2Measurement precision
If specialized authentication devices are deployed, then authentication precision is improved, but availability to consumers decreases
Solution Approach 1:
The authentication system is designed to work with universal portable devices (smartphones, tablets, cameras) that consumers already possess. The system uses standard image capture and communication capabilities, making authentication widely available without requiring specialized or proprietary devices. The server-side processing provides the necessary precision while the client-side remains universal and accessible.
3Reliability
If cryptographic-based authentication is implemented, then security against counterfeiting is improved, but implementation cost increases
Solution Approach 1:
Cryptographic operations and database management are segmented to occur only on the server-side, where they can be implemented once and reused for all authentication operations. Portable devices only need basic image capture and network communication capabilities, significantly reducing manufacturing costs while maintaining strong cryptographic security through server-side processing.
Solution Approach 2:
The system uses digital image capture to create a representation of the security features on the product. Instead of requiring expensive specialized sensors, the system captures images using standard camera components and processes them cryptographically on the server, achieving high security at low implementation cost.
4Reliability
If complex authentication procedures are used, then authentication reliability is improved, but ease of operation decreases
Solution Approach 1:
The portable authentication device automatically performs the authentication process by capturing images of the product's security features and communicating with the authentication server. The complex verification procedures are executed automatically without requiring consumer intervention, maintaining high reliability while ensuring ease of operation through automated self-service authentication.
Solution Approach 2:
The system provides immediate feedback to the consumer through the portable device, indicating whether the product is authentic or counterfeit. This simple binary feedback mechanism makes the system easy to operate while the complex verification processes occur automatically in the background, maintaining both reliability and ease of use.

AI summary
A method and apparatus for protection of products and packaging against counterfeiting using dedicated authentication protocol coupled with portable devices. It is based on the product identification information, i.e., PIN, generated by the product manufacturer, stored in the product database and added to product or packaging in an open and/or a hidden form. The open part is directly available to the consumer before buying, opening or consuming the product or package or damaging its integrity while the hidden part is only revealed after these operations. The hidden information can also be disappearing after a predefined interval of time or number of trials or usages. Both parts are communicated to the authentication server in a predefined order to verify the product or package authenticity. The presence, absence, or multiple requests for the same product PIN, confirm or reject product authenticity or detect attempt at attacking the system or using counterfeited products.
