Product Authenticity Verification via Characteristic Image Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In internet commerce, particularly in auctions and retail, distinguishing genuine from fake products is challenging due to the difficulty in verifying product authenticity from images, leading to potential false products being sold.
Innovation Solution
A product evaluation device and method that includes receiving product specifying information, acquiring designation information for characteristic parts, requesting users to photograph these parts, and outputting an evaluation result based on the similarity between the photographed image and genuine images stored in a database, thereby aiding in authenticating products.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If product authentication is performed using only basic product images uploaded by sellers, then the ease of operation is improved, but the reliability of product authenticity verification deteriorates
Solution Approach 1:
The patent divides product verification into multiple stages: initial basic image upload for ease of listing, and subsequent detailed characteristic part photography for authenticity verification. The system segments the verification process into seller-side uploads and administrator-side detailed examination, allowing both ease of operation and reliability to be satisfied at different stages.
Solution Approach 2:
The system performs preliminary authentication by analyzing characteristic parts of products before allowing full listing or transaction. Administrators conduct preliminary verification of key authentication features (such as logos, serial numbers, or unique design elements) to filter out fake products early, while sellers can still list products quickly using basic images.
2Reliability
If detailed characteristic part photography is required for all products, then the reliability of authenticity verification is improved, but the productivity of product listing deteriorates
Solution Approach 1:
The patent applies different verification requirements to different parts of the product listing process. Basic product images are accepted for all products to maintain listing speed, while detailed characteristic part photography is required only for specific authentication-critical elements. This local differentiation of quality requirements maintains productivity while ensuring reliability where needed.
Solution Approach 2:
Instead of requiring complete detailed verification for all products (excessive action), the system implements partial verification focusing only on characteristic parts that are critical for authentication. This partial action approach maintains high reliability for authenticity verification while minimizing the impact on listing productivity.
3Measurement precision
If administrators manually verify each product image, then the measurement precision of authenticity detection is improved, but the loss of time increases
Solution Approach 1:
The patent replaces manual mechanical verification with automated image recognition and analysis systems. Computers and algorithms automatically compare uploaded images against database records of genuine products, detecting characteristic parts and authentication features. This substitution maintains high measurement precision while dramatically reducing the time loss associated with manual verification.
Solution Approach 2:
The system creates digital copies and databases of genuine product images and characteristic parts. These copies serve as reference standards for automated comparison and verification. By copying authentic product features into a searchable database, the system enables rapid automated verification without sacrificing detection precision.

AI summary
A product evaluation device includes a receiving means for receiving product specifying information for specifying a product attribute, an acquisition means for acquiring designation in formation corresponding to a product attribute specified by the product specifying information from a storage means storing, for each product attribute, a genuine image showing a characteristic part for evaluating whether a product is a genuine product and designation information designating the characteristic part in association with each other, a request means for requesting a user to take a photograph by designating a characteristic part of the product based on the designation information acquired from the storage means and requesting a photographed image obtained by the photographing, and an output means for outputting an evaluation result obtained based on the photographed image provided in response to the request and the genuine image stored in the storage means.
