Detailed Description
In the following description, for purposes of explanation and not limitation, specific details are set forth, such as particular system structures, techniques, etc. in order to provide a thorough understanding of the embodiments of the invention. It will be apparent, however, to one skilled in the art that the present invention may be practiced in other embodiments that depart from these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
In order to explain the technical means of the present invention, the following description will be given by way of specific examples.
Referring to fig. 1, an embodiment of the present invention provides a block chain-based digital rights registration method, including:
step S101: acquiring copyright registration information of user works, and processing the copyright registration information to obtain a copyright secret key;
step S102: encrypting the copyright secret key according to a pre-generated user private key to obtain signature information;
step S103: and issuing the signature information, the copyright secret key and the pre-generated user public key to a copyright block chain network to finish copyright registration.
Blockchains are a term of art in information technology. The block chain is a distributed shared account book and a database, and has the characteristics of decentralization, no tampering, trace retaining in the whole process, traceability, collective maintenance, openness and transparency and the like. The block chain technology does not depend on an additional third-party management mechanism or hardware facilities, does not have central control, and realizes self-verification, transmission and management of information by each node through distributed accounting and storage except for the self-integrated block chain. Decentralization is the most prominent and essential feature of the blockchain. The block chain technology is open source, except that the private information of each transaction party is encrypted, the data of the block chain is open to all people, and anyone can inquire the data of the block chain and develop related applications through a public interface, so that the information of the whole system is highly transparent. Based on the agreed specification and protocol (various mathematical algorithms such as Hash algorithm adopted by similar bitcoin), the whole blockchain system does not depend on other third parties, and all nodes can automatically and safely verify and exchange data in the system without any human intervention. As long as 51% of all data nodes cannot be mastered, network data cannot be arbitrarily manipulated and modified, so that the block chain per se becomes relatively safe, and subjective and artificial data change is avoided. Unless required by legal regulations, the identity information of each block node does not need to be disclosed or verified technically, and information transfer can be performed anonymously.
The characteristics of the block chain ensure the honesty and the transparency of the block chain, and lay a foundation for creating trust for the block chain.
The embodiment of the invention provides a block chain-based digital copyright registration method, which registers digital copyright information by using the characteristics of the block chain, writes the digital copyright information into a block chain account book in a transaction form, and provides a evidence storage form with legal justice in the real society for the confirmation of the copyright of the digital works of a user. The digital copyright protection method can effectively protect the digital copyright information of the digital works, prevent the digital works from being pirated, ensure the real uniqueness of the digital works and reduce the copyright protection difficulty.
In some embodiments, step S101 may include:
step S1011: carrying out hash operation on the copyright registration information to obtain a hash value of the copyright registration information;
step S1012: and combining the registration date with the hash value of the copyright registration information to obtain the copyright secret key.
In some embodiments, step S1011 may include:
step S10111: and carrying out hash operation on the copyright registration information by adopting the IPFS to obtain a hash value of the copyright registration information.
IPFS (InterPlanetary File System) is a File storage and content distribution network protocol that combines the existing successful System distributed hash table, version control System, Self-Certified File System (SFS) with the blockchain. Has the following characteristics:
1. permanent, decentralized saving and sharing of files;
2. point-to-point hypermedia: P2P holds various types of data;
3. versioning: the file modification history can be traced;
4. content addressing: the file is identified by the file content generating an independent hash value, rather than by the file holding location. The files with the same content only exist in one copy in the system, and the storage space is saved.
The embodiment of the invention combines the advantages of IPFS and fuses with the block chain technology to carry out hash operation on copyright registration information.
In some embodiments, after step S103, the method for block chain-based digital rights registration may further include:
step S104: and issuing the signature information, the copyright secret key and the pre-generated user public key to a node in the copyright block chain network for verification, and if a public key matched with the pre-generated user public key exists, finishing the right confirmation.
In some embodiments, before step S101, the method for block chain-based digital rights registration may further include:
step S105: and acquiring registration information of the user, and generating a pre-generated user private key and a pre-generated user public key according to the registration information.
In the embodiment of the invention, before copyright registration, a user firstly registers an account at a client, generates own identity (such as a user public key and a user private key) in a copyright block chain database, and protects the identity of the user by using a password and a real-name system.
In some embodiments, the copyright registration information includes: the user registers an ID, an author, a name of a work, and an original of the work.
In some embodiments, the user work may also be traded on a blockchain. Since the private key of the user is held in the hand of the user and the private key cannot be calculated out through the public key, only the user can initiate transaction and right confirmation. The user can send the signature information, the copyright secret key and the buyer public key to the block chain network, trade the copyright secret key to the buyer, and the buyer can download the original work according to the copyright secret key.
It should be understood that, the sequence numbers of the steps in the foregoing embodiments do not imply an execution sequence, and the execution sequence of each process should be determined by its function and inherent logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.

and the registration confirmation module 24 is configured to issue the signature information, the copyright secret key, and the pre-generated user public key to a node in the copyright block chain network for verification, and if a public key matching the pre-generated user public key exists, complete the right confirmation.
In some embodiments, the apparatus for block chain-based digital rights registration may further include:
and the user registration module is used for acquiring the registration information of the user and generating a pre-generated user private key and a pre-generated user public key according to the registration information.
In some embodiments, the copyright registration information includes: the user registers an ID, an author, a name of a work, and an original of the work.
