Image copyright transaction system based on Hyperledger Fabric

Abstract:
With the development of the Internet, the demand for trading the copyright of digital resources is also greater than before. Traditional copyright trading platforms face many problems, such as low efficiency, high single transaction cost, easy privacy leakage, and insufficient data security. This paper proposes an image copyright transaction system based on Hyperledger Fabric, which adds the author's watermark information in the process of data storage, and uses Fabric to store transaction records. IPFS (Interplanetary File System) expands the storage space of the blockchain, and uses the AES (Advanced Encryption Standard) encryption algorithm to encrypt the IPFS hash, which ensures that others cannot steal image resources. Meanwhile, when the customer downloads the image ensures with a watermark, the actual responsible person can be found once the copyright of the image is infringed. The experimental results show that this system can better meet the security requirements of image copyright transaction. In addition, using tape to test the performance of the Fabric network, the throughput of this system can meet the needs of a larger copyright transaction platform.
