Object Authentication via Camera Barcode Capture and Digital Signatures
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for authenticating objects, such as documents and items, are not forgery-proof and require human intervention, making them inefficient and not applicable in all scenarios, particularly in everyday situations where standardized and simple authentication is desired.
Innovation Solution
A method using image data from a camera to capture barcodes containing third-party public keys, generating digital signatures with the device's private key, and storing the image data with the barcode, allowing for authentication of objects without the need for human certification, enabling easy documentation and verification of object characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods (serial numbers, watermarks, holograms) are used, then authentication can be performed on various objects, but the methods are not forgery-proof and require human intervention
Solution Approach 1:
The patent replaces manual authentication processes with an automated digital system. A camera captures images of the object and a displayed authentication code, which are then processed by a processor to verify authenticity. This substitutes the mechanical/manual process of human authentication with an automated optical and computational system, eliminating the need for human intervention while maintaining security.
Solution Approach 2:
The patent introduces a display device showing an authentication code as an intermediary element. The camera captures both the object and the displayed code, creating a linked verification mechanism. This intermediary display acts as a mediator between the authentication system and the object being verified, enabling automated forgery-proof authentication without requiring human judgment.
2Reliability
If human certification is used for object authentication, then authentication can be performed with judgment and verification, but it requires human intervention and is not standardized
Solution Approach 1:
The patent replaces the human certification process with an automated system comprising a camera, display device, and processor. The camera captures images, the display shows authentication codes, and the processor automatically verifies authenticity by analyzing the captured data. This mechanical-substitution approach eliminates human intervention entirely, standardizing the authentication process while maintaining accuracy through automated verification algorithms.
3Productivity
If manual authentication methods are used, then authentication can be performed on objects, but it is not efficient and cannot be executed with reasonable effort in a standardized form
Solution Approach 1:
The patent replaces manual authentication with an automated system using a camera to capture images, a display to show authentication codes, and a processor to automatically verify authenticity. This mechanical substitution enables rapid, standardized authentication that can be executed efficiently without requiring specialized human expertise or complex manual procedures, significantly improving productivity while maintaining implementation simplicity.
Data Source
AI summary
A method for authenticating an object comprises receiving image data of an image camera of a device comprising the object, recording a barcode, in particular, a two-dimensional barcode, such as a QR code, in the image data with a third-party public key as well as storing the image data with the barcode. The method also comprises generating a digital signature with the device's own private key depending on the image data as well as providing the image data and the digital signature.
