Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The rapid dissemination of images on the internet has made it easy for people to plagiarize and infringe on image copyrights, leading to a need for effective copyright protection solutions.
Innovation Solution
A blockchain-based image processing method that updates historical identification information in a pixel matrix with copyright owner and environment information each time an image is displayed, allowing for secure tracking and protection of image copyrights through encryption and immutability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If image copyright protection is implemented through embedding identification information, then copyright tracking capability is improved, but image quality and visual appearance deteriorate due to visible watermarks or altered pixels
Solution Approach 1:
The patent applies local quality by embedding identification information only in specific pixel regions rather than uniformly across the entire image. The system selectively modifies certain pixels to contain copyright data while preserving the overall visual quality of the image, thus resolving the contradiction between copyright tracking capability and image quality.
Solution Approach 2:
The patent implements nesting by embedding identification information within the pixel structure itself, where copyright data is hidden within the existing pixel matrix. This nested approach allows copyright tracking without adding visible external elements, maintaining image quality while enabling reliable copyright identification.
2Reliability
If identification information is updated each time the image is displayed, then copyright protection reliability is improved, but processing time and system complexity increase
Solution Approach 1:
The patent applies preliminary action by pre-generating and storing multiple versions of identification information in the blockchain before they are needed for copyright protection. When an image is displayed, the system can quickly retrieve and apply the pre-prepared identification data, reducing processing time while maintaining high copyright protection reliability.
Solution Approach 2:
The patent uses copying by creating and storing multiple copies of identification information in the blockchain network. These pre-copied identification data can be rapidly deployed to images without real-time generation delays, thus improving processing efficiency while ensuring reliable copyright protection through the immutability of blockchain-stored identification data.
3Reliability
If blockchain technology is used to store copyright information, then security and immutability are improved, but storage cost and system complexity increase
Solution Approach 1:
The patent applies the extraction principle by separating the storage of identification information from the storage of actual image data. Only the essential copyright identification data is extracted and stored in the blockchain, while the full images remain in conventional storage systems. This reduces blockchain storage complexity and costs while maintaining security and immutability for copyright verification.
Solution Approach 2:
The patent introduces an intermediary layer that manages the interaction between conventional image storage and blockchain storage. This intermediary system handles the complexity of blockchain operations, providing a simplified interface for copyright protection while leveraging the security and immutability of blockchain technology without directly exposing system complexity to end users.

AI summary
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for a blockchain-based image processing are provided. One of the methods comprises: displaying, by a terminal device, a target image; obtaining, by the terminal device, information of a copyright owner of the target image and a current display environment of the target image; sending, by the terminal device, the obtained information to one or more blockchain nodes configured to obtain ciphertext information by encrypting the obtained information and to store the ciphertext information in a blockchain; obtaining, by the terminal device, the ciphertext information from the blockchain; and updating, by the terminal device, historical information in a pixel matrix of the target image based on the ciphertext information.
