Most of the traditional digital copyright management platforms are centralized, which is easy to cause the leakage of private data, that the rights of copyright owners are damaged. An image trading system is implemented using decentralized blockchain technology in this paper. The distributed storage of images is implemented using interplanetary file system (IPFS), the hash address returned by IPFS is stored in the blockchain, which solves the blockchain problems of difficult to capacity expansion and expensive storage space. The private data of images are encrypted storage to ensure the access security of data information. Unique verification of images to ensure that the same image cannot be registered repeatedly. Tests show that the system has good performance and security.
