Blockchain Image Transaction System Copyright Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
E-commerce platforms face challenges in providing users with credible product images and safeguarding the copyright of these images, as images are often photoshopped and can be easily downloaded and reused by other merchants.
Innovation Solution
A blockchain-based image transaction system that authenticates the copyright of uploaded images using image recognition techniques, generates a copyright certificate, and adds verified images to a transaction pool, allowing users to set transaction prices and record usage, ensuring only authorized images are used.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image recognition technique is used to authenticate copyright, then copyright protection is improved, but system complexity increases
Solution Approach 1:
The system divides copyright protection into distinct segments: image upload, hash generation, blockchain storage, and verification. Each segment handles a specific task, making the overall complex system manageable and reliable through modular architecture.
Solution Approach 2:
The patent introduces a blockchain as an intermediary layer between image upload and verification. The blockchain stores hash values and transaction records, acting as a neutral mediator that guarantees copyright authenticity without requiring direct trust between parties, thus improving reliability while maintaining manageable complexity.
2Reliability
If blockchain technology is implemented for image transaction, then copyright protection is improved, but processing time increases
Solution Approach 1:
The system performs preliminary actions by generating image hash values and storing them in the blockchain before actual image transactions occur. This pre-registration of copyright information in the blockchain allows for rapid verification during transactions, reducing processing time while maintaining strong copyright protection.
Solution Approach 2:
Instead of storing entire images in the blockchain, the system stores only hash value copies. This approach maintains copyright protection reliability through immutable blockchain records while significantly reducing processing time and storage requirements compared to storing full image data.
3Measurement precision
If image hash value is stored in blockchain, then verification accuracy is improved, but storage requirements increase
Solution Approach 1:
The patent employs copying by storing only hash value representations of images rather than the actual image data. These hash copies serve as unique identifiers that enable accurate verification while occupying minimal storage space in the blockchain, effectively resolving the contradiction between verification accuracy and storage requirements.
Solution Approach 2:
The system transforms the image data into a different parameter form - converting large binary image data into compact hash value strings. This parameter transformation maintains verification accuracy through the cryptographic properties of hash functions while dramatically reducing the storage requirements in the blockchain.

AI summary
The present application discloses a blockchain-based image transaction system, method, and apparatus. An exemplary method comprises: receiving a target image uploaded from a transaction node in a blockchain, wherein the target image is provided to the transaction node by a user; authenticating, based on image content of the target image, copyright of the target image; if the authentication is successful: generating a copyright certificate of the target image; sending the copyright certificate to the transaction node for the transaction node to display the copyright certificate and a preset prompt window to the user, wherein the preset prompt window inquires the user whether to make the target image as an image available for transaction; and if confirmation information is received, adding the target image into an image transaction pool, wherein the confirmation information indicates the user has determined the target image as an image available for transaction.
