Description
Technical Field
The invention belongs to the technical field of media data copyright protection, and particularly relates to a media data copyright protection method based on a block chain.
Background
With the increasing network traffic and the increasing data size and value, more and more short video and music applications are started, so as to attract a great number of excellent original authors and work processors, but the intellectual property rights of the works are difficult to define, and the related laws and regulations are not sound enough.
And (5) block chains. The block chain technology is developed from the bit currency proposed by the inventor, the concept is proposed by the inventor in the white paper of the bit currency through "chain of blocks", and the block chain technology is translated into the block chain in the earliest Chinese translation version of the white paper of the bit currency. Fundamentally, blockchains are a decentralized, distributed, shared, and immutable database ledger that can store asset and transaction registration information in a peer-to-peer (P2P) network. It links blocks of data that are validated and time stamped by miners, where miners refer to nodes in the blockchain network that are responsible for the production block. Blockchains use elliptic curve cryptography and sha256 hash algorithms to provide strong cryptographic proof of data authentication and integrity.
The chunk data contains a list of all transactions and the hash of the last chunk. The blockchain has a complete history of all transactions and provides distributed trust across the world. Trusted third parties or centralized authorities and services may be breached, compromised or hacked. Even if now trustworthy, they may not behave and become corrupt in the future. In blockchains, each transaction in a shared public ledger is validated by the majority of the consensus of mineworker nodes actively participating in validating and confirming the transaction. In bitcoin networks, miners verify blocks by computing hashes with leading zeros to meet difficulty targets. Once the transaction is verified and validated by consensus, the block data will be immutable, i.e., the data will never be erased or altered. The blockchain may be constructed as: a licensed (or private) network, or an unlicensed or public network opened for anyone to join. The permission blockchain provides better privacy protection and access control.
The interplanetary file system (IPFS). The interplanetary file system is a protocol and peer-to-peer network for storing and sharing data in a distributed file system. IPFS uses content addressing to uniquely identify each file in the global namespace connecting all computing devices, intended to be a common file system for all computing devices. The method integrates the successful ideas of the existing peer-to-peer network protocol and system, including DHT, BitTorrent, Git and SFS, and integrates and develops the technologies to form a comprehensive cohesive system with all excellent characteristics of the technologies. IPFS is similar to the Web, but IPFS can be viewed as a separate BitTorrent cluster and does object swapping in a Git warehouse. In other words, IPFS provides a high-throughput content-addressing-based block storage model, with content-addressed hyperlinks. This forms a generalized merkel directed acyclic graph data structure that can be used to build versioned file systems, blockchains, and even persistent web sites. IPFS combines distributed hash tables, block switching with incentive mechanisms, and self-authenticated namespaces. IPFS has no single point of failure and the nodes do not need to trust each other.
The current media data copyright protection method is mainly to confirm the ownership of an author through a digital watermarking technology or a digital signature and other authorization confirming technologies, and then to deliver the information to a central registration authority for recording and protection.
However, the main defects of the existing method are as follows:
1. copyright information is recorded and stored by a central registration mechanism, and the problems of information tampering, information loss, complex information registration process, low information updating speed and the like are easy to occur.
2. The right confirmation and registration can not be completed in time, the copyright registration under the existing method needs long time, the procedure is complex, the works are not easy to store during the copyright application period, the spreading is limited, and the value of the works can not be well realized.

Detailed Description
The block chain-based media data copyright protection method provided by the invention is described in detail below with reference to the accompanying drawings and specific embodiments.
The media data copyright protection method based on the block chain adopts a double-chain structure, the first chain is a copyright chain, the second chain is a certificate chain, information recorded by the copyright chain is copyright change information including copyright statement, copyright assignment, copyright authorization and the like, and each operation can be a transaction and stored in a block. When a user wants to use works on the copyright chain to perform re-creation, the user firstly needs to apply or purchase the copyright to the original author, records the copyright in the first chain, and then records the re-creation method and the re-created works on the certificate chain as transaction contents.
As shown in fig. 1 to fig. 3, the method for protecting media data copyright based on a block chain according to the present invention includes the following steps performed in sequence:
1) constructing a system with a double-chain structure, wherein the system consists of a copyright chain and a storage chain; the copyright chain is used for recording all copyright operations, including copyright statement, copyright assignment and copyright authorization; the evidence storing chain is used for issuing a record and re-authoring author to obtain an authorization record of the original author and a re-authoring process; users of the system are divided into original authors, users who buy or use copyrights of other works and re-creation authors who re-create with other works; the transaction types of the system are divided into copyright statement, copyright assignment, copyright authorization and re-authored work release; wherein, the copyright statement is represented by 01, that is, the user A declares the copyright of a certain work; copyright authorization is represented by 02, namely the user B is allowed to use but ownership still belongs to the user A, the actual owner of the copyright does not change, the symbol in the 02 type represents whether the user B is allowed to authorize the copyright to other people, namely 020 represents that only the user B can use, 021, 022 and 023 respectively represent that the user B is allowed to authorize the copyright to other one, two or three people; copyright assignment is denoted by 03, namely, the user A transfers the copyright to other people by means of selling and giving; the re-authoring work distribution is denoted by 04, i.e., the re-authoring author distributes its own work.
2) When an original author is used as a user A to register original author edition right for the first time, the original author uploads original works to an interplanetary file system to obtain a unique identifier of the whole network; then, the user A calculates the file hash value of the original work, digitally signs the file hash value by using a private key, and then constructs a new transaction, wherein the input of the new transaction is a creation block which is similar to the input of the transaction of the coinage in the bitcoin, so the new transaction can be regarded as the creation block and is output as the account address of the user A; the new transaction metadata comprises information which can identify copyright, such as IPFS address of original works, digital signature of a user A on the file Hash, a public key of the user A, transaction type and timestamp, and then the transaction is broadcasted in the network; the miners can obtain the original works through the IPFS address and verify the file Hash in the digital signature, so that the consensus is achieved, and then the data is linked up;
3) when a certain user B wants to use the original work copyright of the user A, negotiation with the user A is needed firstly, after the user A authorizes the copyright or purchases the copyright successfully, the user A can initiate a transaction on a copyright chain, the input of the transaction is the account address of the user A, the output of the transaction is the account address of the user B, and then broadcasting is carried out in the network; the transaction metadata comprises a transaction ID when the user A declares the copyright of the original work, a digital signature of the user A on both a hash of the transferred file and a public key of the user B, the public key of the user A and the transaction type (namely copyright authorization or copyright transfer). The miners firstly obtain the hash of the transfer file according to the transaction ID and then compare the hash with the hash of the file in signature verification to determine whether the hash is consistent. After the verification is successful, the consensus is achieved, and the data chaining can be realized;
4) a re-creation author who wants to re-process and create the original works of the user A is used as a user C and needs to record information authorized by the user A; assuming that a user A registers the copyright of a video1 on a copyright chain, and a user C wants to perform reprocessing creation on the video1, the user C needs to negotiate with the user A to obtain a use permission through purchase or authorization; after the negotiation is consistent, the user A initiates a new transaction on the copyright chain, the user C is declared to be capable of using the video1, the transaction input address is the address of the user A, the output address is the address of the user C, and the transaction metadata is the same as that in the step 2); (ii) a Then, the user C carries out reprocessing creation of the video1, in order to ensure that the user C really uses the video1 and ensure that a certificate chain miner can commonly identify a file hash of the re-created works, the user C needs to record and publish the creation method of the user C on the certificate chain in a script making mode so as to ensure that all people can make the same works by using the same method;
the method designs a set of perfect script language and a script execution mode to ensure that all people can produce the same works according to the script method, wherein part of commonly used video, audio and image operation methods, operation codes and meanings thereof are shown in the following table:
the making script is used for completely recording all operations of the re-creation author on the original work, and when verification is carried out, only the original work and the file hash in the re-creation author transaction need to be put into a script verification system, so that whether the original work and the re-creation author transaction are consistent or not can be verified.
The transaction metadata comprises a block number and a transaction index number of a transaction place authorized by the user A and obtained by the user C, and a production script, a file hash and a transaction type which are generated by the corresponding operation of reprocessing the creative work by the user C; the production script should be similar to the following:
< checkHash, hash, (opcode used by user C) >
Then the transaction is broadcasted on the network; when the miners perform the packaging transaction, the corresponding authorized transaction is verified in the corresponding block, then the manufacturing script is executed to verify the hash of the file, if the returned result is real, the common identification is passed, and then the data is linked up.
