Image copyright protection system based on blockchain and binarization ORB algorithm

The widespread dissemination and sharing of digital images have led to an urgent need for image copyright protection. To address this challenge, this study proposes a comprehensive image copyright protection system based on blockchain and image processing algorithms. Firstly, image features are extracted through binarization processing and the ORB algorithm. The GMS algorithm is then employed for feature selection to enhance the accuracy of feature matching. Subsequently, the InterPlanetary File System (IPFS) is utilized to store images and related data in a decentralized network, ensuring the immutability and traceability of information. Finally, image copyright management throughout its lifecycle, including registration, querying, and transfer, is implemented through Ethereum smart contracts.
