Solution Overview

Problem

Existing technologies for authenticating products and detecting theft are inadequate, as they lack comprehensive solutions for robust anti-counterfeiting, thorough monitoring, and lost item detection, leading to persistent issues of product counterfeiting and theft.

Innovation Solution

The use of encrypted near-field communication (NFC) tags encoded with unique identifiers and encryption keys, which generate secure encrypted messages upon scanning, allowing for product authentication and theft detection through verification servers that maintain databases of product information and ownership profiles.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard barcodes, RFID tags, holograms, and tamper-proof labels are used for product authentication, then implementation is simple and cost-effective, but security is insufficient and tracking abilities are limited

Engineering Contradiction:
Improveproduct authentication securityVSAvoidauthentication system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple authentication mechanisms into a single integrated system: NFC tags embedded in products, mobile device scanning capabilities, encrypted communication protocols, and backend verification servers work together as one unified authentication ecosystem, replacing the need for separate security measures

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The NFC tag system serves multiple functions simultaneously: it provides product authentication, enables theft detection through ownership tracking, facilitates lost item recovery, and integrates with point-of-sale systems for inventory management, making a single system that performs diverse security and tracking tasks

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

2Reliability

If advanced encrypted communication systems with mobile capabilities and backend verification are implemented, then product authentication security is improved, but system complexity and implementation difficulty increase

Engineering Contradiction:
Improveanti-counterfeiting capabilityVSAvoidsystem implementation ease
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The system enables self-service authentication where consumers use their own mobile devices to scan and verify product authenticity without requiring specialized equipment or expert intervention. The mobile device automatically handles encrypted communication with the NFC tag and verifies responses against the backend server

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

NFC tags are pre-encoded with unique identifiers and encryption keys during product manufacturing, and ownership information is registered in advance in the backend system. This preliminary setup enables immediate authentication and theft detection capabilities without requiring additional configuration at the point of use

Inventive Principle:
Principle #10Preliminary action

3Reliability

If NFC tags with unique identifiers and encryption keys are used, then product authentication and theft detection are enhanced, but manufacturing and programming costs increase

Engineering Contradiction:
Improvetheft detection capabilityVSAvoidtag programming complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent replaces traditional mechanical or manual tagging methods with electronic NFC tags that can be programmatically encoded. The unique identifiers and encryption keys are digitally injected into the NFC tags through automated programming processes, eliminating manual configuration and reducing human error

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The system changes the fundamental parameters of product identification from simple visual codes (barcodes) to encrypted digital identifiers stored in NFC tags. This parameter change enables cryptographic security features while maintaining the ability to mass-produce and programmatically manage tags through standardized interfaces

Inventive Principle:
Principle #35Parameter changes

4Loss of information

If comprehensive tracking systems with ownership profiles and point of sale integration are implemented, then lost item detection and ownership tracking are improved, but system complexity and data management requirements increase

Engineering Contradiction:
Improveproduct ownership trackingVSAvoiddatabase management complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The backend verification server acts as an intermediary that manages the complexity of ownership tracking and data integration. It maintains the database of registered products and ownership profiles, processes authentication requests, and coordinates with point-of-sale systems, shielding the user from underlying system complexity while enabling comprehensive tracking

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

A system and method for product authentication and theft detection using encrypted NFC tags is disclosed. Each NFC tag is encoded with a unique identifier, counter algorithm, and encryption key. A scanning device scans the NFC tags and receives an encrypted message generated using the unique ID, counter value, and encryption key. A verification server stores encryption keys and associated decryption keys, maintains a database associating unique IDs with products, receives encrypted messages, decrypts them with the decryption keys, and verifies authenticity and ownership. In some aspects, an owner can register a product to their profile by scanning the tag. Ownership transfers are updated by changing the association. By maintaining unique IDs of store inventory and comparing to point of sale data, missing products are determined as stolen. When a stolen tag is scanned, a warning is returned.
