Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-counterfeiting techniques are difficult for average users to perform in the field without specialized readers and can be easily duplicated or reverse-engineered, making them unreliable for authenticating objects quickly and efficiently.
Innovation Solution
A method and system using a portable, handheld image capture device to authenticate objects by capturing an image of a random distribution of three-dimensional elements, processing the image to generate an image pattern, and comparing it to a stored authentication pattern signature, either locally or remotely, using a mobile electronic device like a smartphone, without requiring specialized skills or equipment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If specialized readers and laboratory settings are used for authentication, then measurement precision and reliability are improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent replaces specialized mechanical/optical readers with a portable electronic device containing an image capture device (camera). The authentication system substitutes complex specialized reading equipment with a common smartphone or portable device that captures images of the random distribution of three-dimensional elements, processes them through software algorithms, and performs authentication without requiring laboratory settings or specialized equipment.
2Measurement precision
If code comparison with database is performed for authentication, then measurement precision is improved, but loss of time and productivity deteriorate
Solution Approach 1:
The patent performs preliminary actions by capturing the authentication pattern (random distribution of three-dimensional elements) during manufacturing and storing it in a database. During authentication, the system quickly captures an image of the elements, processes it to generate a code, and compares it against the pre-stored authentication pattern. This preliminary setup enables rapid field authentication without time-consuming manual procedures.
3Ease of manufacture
If generic identification technologies are used, then ease of manufacture is improved, but reliability deteriorates due to easy duplication
Solution Approach 1:
The patent employs asymmetric authentication by using a random distribution of three-dimensional elements that creates a unique, unpredictable pattern for each authentication label. This random asymmetric pattern is captured as an image and stored as the authentication pattern. The asymmetry and randomness make each label unique and extremely difficult to duplicate, while the label itself can be manufactured using standard printing and application processes.

Function Achieved in This Case
Enables quick and reliable authentication of objects in the field by average users, resistant to duplication or reverse-engineering, as the three-dimensional elements and image processing techniques provide a secure and efficient means to verify authenticity.
Implementation Method 1
aiming a portable, handheld, image capture device at the object to capture return light from the elements

AI summary
A method of, and a system and a label for, authenticating an object in situ create an authentication pattern signature for the object to be authenticated, associate a random distribution of multiple, three-dimensional elements with the object, aim a portable, handheld, image capture device at the object to capture return light from the elements as a single image, verify from the single image that the elements are three-dimensional, process the single image to generate an image pattern of the elements, compare the image pattern with the authentication pattern signature, and indicate that the object is authentic when the image pattern matches the authentication pattern signature.
