Blockchain-Based Protected Digital Copyright Management with Digital Watermarking

Abstract

In the digital era, more and more information is shared through the internet. This may lead to editing, transmitting, misusing detection and usage of information by unauthorized persons. To avoid such a problem we use the digital right management (DRM) with blockchain. In our daily life, blockchain is a powerful utensil to share the data in decentralized and distributed technology. The DRM process provides security and authentication for the content and owner of the data. In our proposed system, the following steps have been implemented Watermark Embedding with Discrete Wavelet Transform (DWT), Arnold Transform (AT), Perceptual Hash, Hash Code generation (md5), Watermark Extraction and Blockchain Creation. Discrete Wavelet Transform provides better image quality and robustness. Arnold Transform provides the best watermark encryption. The hash code generation gives a numeric value which helps in the recognizable proof of a ediget during equality testing. Blockchain is used to store the information in a secured manner and also provide timestamp authentication. Watermark extraction is achieved with the inverse of Arnold transform, inverse Discrete Wavelet Transform with the matching of hash code. This system provides secure transactions with copyright-protected data and safe transparent management.
