Abstract
The invention provides a multifunctional digital copyright management method and a system, which comprises an electronic terminal and a server, wherein the electronic terminal comprises a content authentication and authorization module, a key management module and a copyright release module.
Description
Technical Field
The invention relates to the technical field of digital rights management, in particular to a multifunctional digital rights management method and a multifunctional digital rights management system.
Background
Digital Rights Management (DRM) is currently the main control means for copyright protection of Digital works spread in networks. DRM is defined by the american publisher association: "techniques, tools and processes for protecting intellectual property during the trading of digital content". DRM is a system solution including information security technology, which protects the copyright of the creator and owner of digital information while ensuring the normal use of digital information (such as digital images, audio, video, etc.) by a legitimate user with rights, obtains legitimate income according to copyright information, and can identify the copyright ownership of digital information and the authenticity of copyright information when the copyright is infringed. The digital copyright protection technology is a series of software and hardware technologies for protecting intellectual property rights of various digital contents, is used for guaranteeing legal use of the digital contents in the whole life cycle, balancing benefits and requirements of all roles in a digital content value chain and promoting development of the whole digital market and information transmission. And in particular, various processes for describing, identifying, transacting, securing, monitoring, and tracking various forms of use of digital assets. Digital rights protection technology involves the entire digital content value chain throughout the entire content distribution process from production to distribution, from sale to use of the digital content.
The most common DRM technologies include digital watermarking, digital encryption, and digital certificate, but the use of these technologies cannot achieve complete protection of the content.
Disclosure of Invention
The invention aims to overcome the defect that the existing digital copyright management technology cannot really and perfectly protect digital content.
In order to solve the technical problems, the technical scheme provided by the invention is as follows: a multifunctional digital copyright management system comprises an electronic terminal and a server, wherein the electronic terminal comprises a content authentication authorization module, a key management module and a copyright release module.
The content authentication module is used for registering user identity information and digital identification information and granting authority authentication to the registered user.
The key management module comprises a key generation module, a key release module and a key storage module.
The copyright release module is used for receiving the key information sent by the content encryption module, obtaining the public key information of the electronic terminal from the key management module, generating the authorization information of the digital copyright and sending the generated authorization information to the server.
The server comprises a request processing module, a digital information calibration module and a response module.
A multifunctional digital rights management method, comprising the steps of:
s1: the electronic terminal firstly carries out registration information on the user through the content authentication module, acquires identity information and digital identification information of the user, and grants authority authentication to the registered user.
S2: the method comprises the steps of encrypting a file pre-encrypted by a user through a key management module, generating a public key by a license key seed and a key identification through the key management module, storing the key identification, the website address of a certificate issuing center, the version number and other information in the head of an encrypted media file through a key issuing module, signing the head of the encrypted media file according to a private signature key, then encrypting content and packaging the encrypted content and the head into a media file, and finally storing the generated public key through a key storage module.
S3: and receiving the key information sent by the content encryption module through a copyright release module, obtaining public key information of the electronic terminal from the key management module, generating authorization information of the digital copyright, and sending the generated authorization information to the server.
Compared with the prior art, the invention has the advantages that: the invention authenticates the authority of the terminal user through the content authentication authorization module, encrypts the digital information by generating the key through the key management module, and finally authenticates and authorizes the digital copyright information of the user through the copyright issuing module, thereby effectively and perfectly protecting the digital copyright information of the user.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
With reference to the accompanying drawings, a multifunctional digital rights management method and system includes an electronic terminal 1 and a server 5, where the electronic terminal 1 includes a content authentication authorization module 2, a key management module 3, and a rights issuing module 4.
The content authentication module is used for registering user identity information and digital identification information and granting authority authentication to the registered user, and the electronic terminal 1 firstly performs the registration information to the user through the content authentication module, and simultaneously acquires the user identity information and the digital identification information and grants the authority authentication to the registered user.
The key management module 3 includes a key generation module 6, a key distribution module 7 and a key storage module 8.
The copyright release module 4 is configured to receive the key information sent by the content encryption module, obtain public key information of the electronic terminal 1 from the key management module 3, generate authorization information of a digital copyright, send the generated authorization information to the server 5, encrypt a file pre-encrypted by a user through the key management module 3, generate a public key by using the license key seed and the key identifier through the key management module 3, store the key identifier, a website address of a certificate issuing center, a version number and other information in a head of an encrypted media file through the key release module 7, sign the head of the encrypted media file according to a private signature key, encrypt content and package the head into a media file, and finally store the generated public key through the key storage module 8.
The key information sent by the content encryption module is received by the copyright release module 4, the public key information of the electronic terminal 1 is obtained from the key management module 3, and the key information is also used for generating authorization information of digital copyright and sending the generated authorization information to the server 5.
The server 5 comprises a request processing module 9, a digital information calibration module 10 and a response module 11, wherein the request processing module 9 is used for receiving the punishment request sent by the user, approving the punishment request through the digital information calibration module 10 according to the identity information of the user and the identification information of the digital content, finally responding the digital content at the punishment type of the user through the response module 11, and generating the punishment information after the user punishs the digital content at the punishment type.
