Digital rights protection method based on block chain technology

Abstract

The invention discloses a digital copyright protection method based on a block chain technology. The digital copyright protection method comprises a digital copyright protection model based on the block chain technology and a copyright protection protocol. The digital copyright protection model comprises a user, a Web client, a block chain server and a block chain network. A user registers and identifies through the Web client, generated transaction information Tx is processed through the block chain server, and information consensus is carried out through a consensus mechanism of the block chain network; the copyright protection protocol comprises a digital copyright registration sub-protocol and a digital copyright transfer sub-protocol. Information leakage cannot be caused even if the scheme is attacked; according to the method and the system, piracy and copying behaviors of the digital works are prevented, malicious users cannot perform camouflage attacks, piracy infringement behaviors can be solved, the real uniqueness of the digital works is ensured, and the calculation cost of a Simhash (locality sensitive hash) algorithm is greatly reduced.
