Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital photographs are easily edited and tampered with, making it challenging to obtain trustworthy evidence, particularly in industries that rely on remote or virtual inspections, as existing technologies allow for metadata manipulation and image alteration.
Innovation Solution
A system that authenticates electronic images by using a reverse image search, generating and comparing hash signatures, and writing these signatures to a decentralized ledger to ensure the integrity and immutability of the images from generation to authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If digital photographs are easily edited and metadata manipulation technologies are used, then image processing flexibility and ease of operation are improved, but image authenticity and reliability deteriorate
Solution Approach 1:
The system performs preliminary actions by capturing images through a dedicated application that records metadata at the moment of capture, then immediately generates and stores hash values on the blockchain before any potential editing occurs. This establishes a timestamped, immutable record of the original image state, preventing later tampering while maintaining the ability to process images through controlled workflows.
Solution Approach 2:
The patent introduces an intermediary layer in the form of a blockchain-based authentication system that sits between image capture and final use. This intermediary generates cryptographic hash values and timestamps that act as trusted mediators, verifying image integrity without requiring direct trust in the image editing or processing tools used afterward.
2Productivity
If remote inspection technologies using images are implemented, then inspection efficiency and productivity are improved, but image tampering and metadata manipulation increase
Solution Approach 1:
The system implements feedback mechanisms where the blockchain continuously monitors and records the hash values of images at various stages of the inspection process. This feedback loop allows any party to verify whether an image has been tampered with by comparing current hash values against the recorded blockchain history, ensuring integrity while enabling efficient remote inspections.
Solution Approach 2:
Before images are used in remote inspections, the system performs preliminary authentication by capturing images through a controlled application, generating hash values, and recording them on the blockchain. This preliminary action establishes a chain of custody that maintains image integrity throughout the entire inspection workflow, from capture to final analysis.
3Reliability
If image authentication applications are used to prevent tampering, then image reliability is improved, but system complexity increases
Solution Approach 1:
The patent extracts the complex cryptographic and blockchain infrastructure from the image capture application itself, separating these functions into independent, distributed components. The application only needs to generate and transmit hash values, while the blockchain network handles the complex verification and recording, reducing the complexity burden on individual devices and applications.
Solution Approach 2:
The blockchain serves as a distributed intermediary that handles the complex authentication logic externally. Instead of requiring complex verification systems within each application, the blockchain acts as a trusted mediator that records hash values and provides cryptographic proof of image integrity, simplifying the overall system architecture while maintaining high reliability.

AI summary
Disclosed is improved technology for authenticating electronic images and storing proof of tampering or non-tampering on the blockchain. An image authentication application of a user device may generate an image. The user device may generate an image hash of the image using a hash function. The image hash may be written to the blockchain. This may occur immediately after the image has been taken. The user device may upload the image to an authentication server, which authenticates the image. At various times, such as after receipt, during authentication, and/or after authentication, the authentication server may generate an image hash of the image using the hash function. The authentication server may write the image hash(es) to the blockchain. As such, a state of the image at various times may be recorded on the blockchain to determine whether or not the image has been tampered with between various times.
