Blockmarking: Hybrid model of blockchain and watermarking technique for copyright protection

Digital contents have become more popular and rapid in recent years. The need of techniques for digital content protection is also quickly required. Various watermarking techniques are proposed for protecting the digital contents. Blockchain technology has also become very popular and applied on many solutions. This paper proposes a new hybrid model based on the combination of blockchain and watermarking method. The main purpose is not only to achieve the goal of image copyright protection but also store the image into the blockchain network. Since our proposed method employs the blockchain mechanism, the digital contents authentication algorithm does not need any third party to join and confirm. Our experimental results show that the our method successfully achieved the purpose of digital copyright protection. © 2022 ACM.
