Abstract

In the digital information age, distributed file storage technologies like the InterPlanetary File System (IPFS) have gained considerable traction as a means of storing and disseminating media content. Despite the advantages of decentralized storage, the proliferation of decentralized technologies has highlighted the need to address the issue of file ownership. The aim of this paper is to address the critical issues of source verification and digital copyright protection for IPFS image files. To this end, an innovative approach is proposed that integrates blockchain, digital signature, and blind watermarking. Blockchain technology functions as a decentralized and tamper-resistant ledger, recording and verifying the source information of files, thereby establishing credible evidence of file origin. A digital signature serves to authenticate the identity and integrity of the individual responsible for uploading the file, ensuring data security. Furthermore, blind watermarking is employed to embed invisible information within images, thereby safeguarding digital copyrights and enabling file traceability. To further optimize the efficiency of file retrieval within IPFS, a dual-layer Distributed Hash Table (DHT) indexing structure is proposed. This structure divides file index information into a global index layer and a local index layer, significantly reducing retrieval time and network overhead. The feasibility of the proposed approach is demonstrated through practical examples, providing an effective solution to the copyright protection issues associated with IPFS image files.
