| Summary: | Digital Rights Management(DRM) is an information security technology that protects the rights and interests of publishers of digital publications. It guarantees authorized users to use digital information and protects the interests of copyright owners. However, the traditional central copyright protection method has some problems such as low security and rough authority control, which makes piracy and infringement occur frequently. Blockchain has the characteristics of decentralization, tamper-proof, public and transparency, which provides a new idea to solve the problem of copyright protection. This paper analyzes and compares the traditional digital copyright protection method and the copyright protection method based on blockchain, and puts forward the prospect for the future.
