Abstract

A digital rights management system and a digital rights management method are provided. The digital rights management system includes an authority management module, a user confirmation module and an authority blockchain. The authority management module is configured for: receiving a user authority information corresponding to a user end from a service providing; sending user authority information to the user confirmation module; receiving an identification code corresponding to the user authority information from the user confirmation module; and sending and storing the user authority information and the identification code into the authority blockchain. Therefore, the authority management module, the user confirmation module and the authority blockchain manage and protect digital rights.
