- W4387570168 abstract "The traditional copyright protection method has some problems, such as difficulty in confirming the right, complicated steps and long time for confirming the right, which can not effectively protect the legitimate rights and interests of the original author. Under the blockchain technology, the process of reshaping the trust mechanism through decentralization, and the trust mechanism determines the right subject and determines that the right subject is beneficial to copyright ownership can clarify the copyright ownership of digital music. Based on the in-depth analysis of existing technologies, standards and systems, this paper designs and implements a complete digital music copyright protection system. When reading resources, users are required to provide relevant authentication information, and users can browse resources only after providing correct authentication information and meeting the validity period of resources. A digital audio watermarking algorithm based on chaotic encryption is designed, which introduces chaos theory. Firstly, the watermark information is encrypted by low-dimensional chaotic mapping, and then the watermark is encrypted by three-dimensional Rossler chaotic attractor, which further improves the security of the watermark and enhances the robustness of the watermark. The research results show that the embedding time of this algorithm is kept within 2 s, which meets the real-time embedding requirements of watermark. The algorithm adopts the way of embedding multiple identical watermarks at the same time, which improves the robustness of watermarks." @default.
