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 increase of network traffic and the increasing increase of data size and value, more and more short video and music applications are emerging, thereby attracting a great deal of excellent originators and work processors, but intellectual property rights of the works are difficult to define, and related laws and regulations are not sound enough.
A blockchain. The blockchain technology was developed from bitcoin proposed by the clever in the middle, who proposed the concept in the white book of bitcoin as "chain of blocks", which was translated into blockchains in the earliest bitcoin white book chinese translation. Basically, blockchains are a kind of decentralized, distributed, shared and immutable database ledgers that can store registration information for assets and transactions in a peer-to-peer (P2P) network. It links blocks of data that are verified and time stamped by miners, where miners refer to nodes in the blockchain network that are responsible for producing the blocks. Blockchains provide strong cryptographic proof for data authentication and integrity using elliptic curve cryptography and sha256 hash algorithms.
The chunk data contains a list of all transactions and the hash of the last chunk. Blockchains have a complete history of all transactions and provide cross-border global distributed trust. Trusted third parties or centralized authorities and services may be destroyed, compromised or hacked. Even though now trustworthy, they may behave endlessly and become corrupt in the future. In the blockchain, each transaction in a shared public ledger is verified by the majority of the commonalities of mineworker nodes that are actively involved in verifying and validating the transaction. In a bitcoin network, miners verify a block by computing a hash with a leading zero to meet a difficulty target. Once the transaction is authenticated and validated by the consensus, the block data will be immutable, i.e., the data will never be erased or altered. The blockchain may be constructed as: licensed (or private) networks, or public networks that are unlicensed or open for anyone to join. The licensed blockchain provides better privacy protection and access control.
Interplanetary file system (IPFS). The interstellar 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 that connects all computing devices, intended to be a generic file system for all computing devices. It integrates the successful ideas of the existing peer-to-peer network protocols and systems, including the distributed hash table DHT, bitTorrent, git and the SFS, and fuses and develops these technologies into a comprehensive cohesive system possessing all the excellent characteristics of the above technologies. IPFS is similar to Web, but IPFS can be seen as a single BitTorrent cluster and subject exchange in a Git repository. In other words, IPFS provides a high throughput content-addressed block storage model with content-addressed hyperlinks. This forms a generalized merck directed acyclic graph data structure with which a versioned file system, blockchain, or even a persistent website can be built. IPFS incorporates a distributed hash table, block exchange with incentive mechanism and a self-authenticated namespace. IPFS has no single point of failure and nodes do not need to trust each other.
The current media data copyright protection method mainly confirms the ownership of an author through digital watermarking technology or digital signature and other right-confirming technologies, and then the information is delivered to a central registration mechanism for recording and protection.
However, the existing method has the following two main defects:
1. the copyright information is recorded and stored by a central registration mechanism, so that the problems of information tampering, information loss, complex information registration flow, low information updating speed and the like are easy to occur.
2. The right confirmation and registration cannot be completed in time, the copyright registration in the existing method requires long time, the procedure is complex, the work is not easy to store during the copyright application, and the value of the work cannot be well realized due to limited propagation.
