A Zero-watermark Algorithm for Copyright Protection of Remote Sensing Image Based on Blockchain

Abstract

In order to solve the problem that the existing zero-watermark technology relies on the third-party IPR management organization, this paper proposes a new zero- watermark algorithm based on blockchain. The algorithm considers the multi-band characteristics of remote sensing image. It uses K-L transform, NSCT transform, SVD and other technical means to obtain the robust zero-watermark image of remote sensing image. The zero-watermark is stored on the blockchain by a zero-watermark registration system based on IPFS and Hyperledger Fabric. The experimental results show that the algorithm based on blockchain proposed in this paper realizes the lossless protection of data copyright. Moreover, this paper proves that blockchain can replace third-party IPR management organization.
