Design scheme for copyright management system using blockchain and IPFS

Abstract

The existing technologies allow to distribute digital images quickly and easily through the internet. The misuse of digital images, intentionally or unintentionally, increases dramatically especially with copyright protection that facing a major challenge. There are many unsolved problems in the centralized copyright office registration such as high cost services, long time processing, store copyright information in the centralized server and susceptibility to tampering registration records. In this paper, a schema of copyright digital management system is designed based on blockchain, Inter Planetary File System (IPFS) and Perceptual hash image. Blockchain technology evolvement has very changed the network that makes numerous applications become distributed and decentralized without loss of security. Moreover, our solution exploits the benefits of IPFS to store image and text file of copyright owner’s information on a decentralized file system. Perceptual image hashing is used for authentication based on the understanding of the image content. The scheme uses Point to Point (P2P) network to improve the copyright image management, make the distribution of copyrighted work without third part and finally protect the copyright owner.
