Most people do not understand the knowledge points of this article "what is the relationship between blockchain and digital copyright technology", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article, let's take a look at this article "what is the relationship between blockchain and digital copyright technology".

Digital copyright has always been the "hot cake" of block chain landing. It has natural advantages: it is online originally, and there is no closed loop online and offline.

The definition of copyright has also been expanded after entering the digital age.

In addition to the traditional right of reproduction, the right of distribution and the right of information network dissemination, digital copyright also adds the right of contact with works without the author's permission, the right of public communication which integrates the right of dissemination, the right of projection and the right of information network dissemination, as well as the right of interpretation, including adaptation, translation and annotation.

The future and limitations of digital copyright still lie in "protection" and "transaction".

Unlike many combinations between the financial field and blockchain, digital copyright still has a lot of room for imagination in blockchain technology, and its depth and breadth have not been fully explored.

In March this year, Ali Music reached a strategic cooperation agreement with Merlin (an independent music digital rights agency). Ali Music publicly announced that it hopes to provide comprehensive protection for the legitimate rights and interests of independent music companies, musicians and music works through AI and blockchain technology.

In the past six months, Ali Music has not made public any progress in the blockchain. It was not until the "Cloud Conference" a few days ago that Ali Music joined hands with Wu Yiqun, the founder of TASchain, to talk about blockchain + digital rights in public.

The meat of "Digital copyright + Block chain" is fragrant, but there is more than one wolf.

Overseas, Intel has filed digital rights patents based on blockchain, and Spotify, the world's largest music streaming service, bought Mediachain, a company that uses blockchain to provide data solutions, in April last year.

In a twinkling of an eye, in addition to Huawei, which uses private keys to protect copyright, Baidu also launched a picture copyright service platform based on block chain after compensating Oriental IC picture copyright 210000.

On the one hand, there is the idea of open sharing in the network era, and on the other hand, the current situation of copyright protection can not be ignored. Whether digital copyright can adapt to the transformation and whether the distribution of multi-stakeholders is fair, many people have handed over the pen to write the answer to the "blockchain technology".

Symptomatic digital copyright

With the development of Internet, P2P and digitization, content replication and distribution become more convenient, which leads to lower cost of unauthorized use, copy and distribution.

In the existing digital copyright, there are some problems in the field of protection, such as the confirmation of registration, the lack of means of investigation and collection of evidence and so on. In the field of transaction, digital copyright has not become more transparent and fair because of digitalization and networking.

Traditional digital rights management (DRM) is that publishers use a series of information technologies to protect the digitization of copyrighted content and the supply of network information services, while controlling the use process of digital content and equipment after being sold. The core idea is to control users' operations such as accessing, changing, sharing, copying, printing and saving files through user licenses, so as to protect the rights and interests of content providers (copyright owners).

It is worth noting that DRM technology is mostly independently developed by various publishers, and the technologies are incompatible, so it is easy to form multiple copyright centers. Jobs released an open letter on February 6, 2007, saying that DRM still could not guarantee that songs purchased from big companies would not be pirated, and that users using DRM technology were more vulnerable to disclosure of privacy information.

The blockchain technology makes digital rights pay attention to the significant impact of its innovation on trust. As a new subversive technology, blockchain integrates a number of basic technologies, such as distributed bookkeeping, immutability, intelligent contracts, and so on, as a mechanism that promotes strangers to build trust.

As for copyright protection, there have been mature explorations at home and abroad, and more and more companies apply blockchain technology to their own fields. As a legitimate streaming music service platform, Sweden's Spotify uses blockchain technology to track royalty payments to ensure that creators and copyright holders get a corresponding return. What can be seen behind this is that "the platform does not know who to pay for the creation."

This issue was also mentioned in the "Ali Music Special performance of the Yunqi Conference", which ended not long ago. Wu Yiqun, TASchain, who participated in the discussion of "music industry blockchain" with Ali Music, once mentioned that the current copyright market is not particularly healthy.

Those big copyright dealers, in the layer-by-layer distribution, they are the biggest head of profit. And artists, they do not get a lot of income, they still have to rely on commercial performances to get profits.

Referring to the combination of blockchain and digital rights in digital music, Wu Yiqun said this is what Xiami began to think about in the first place.

If you search on the Internet, you can find it. We applied for a patent to make shrimp at the earliest. At that time, we thought, now that there are more and more small studios and independent brands, is it possible for these independent labels and fans to jointly operate and maintain a node network? In this way, the platform may be more of a distribution and aggregation of content.

If the blockchain is used to build this system, then the function of centralizing the service bearer may be weaker. The advantage is that small studios and artists will be willing to come in and play the game. They will see how many times their songs have been heard and downloaded. In other words, they can confirm that the copyright of a song is their own. And such a system is fair, not that a certain platform has the final say.

The same is true of reality. In the music industry, as the first input-output "content producer" (songwriter, composer, producer), it is also the last person to make a profit.

They do not know how their royalty income is calculated, and there is no channel to understand the way the audience listens to music, including "how to listen", "how much" and "how much can I get".

* * "decentralization" to maintain digital copyright * *

In the technical characteristics of "decentralization" of the blockchain, its nodes are decentralized, open and peer-to-peer, which ensures that the data generated on any block will be synchronously broadcast to other nodes for verification, and the verification results will be stored on all nodes synchronously.

Compared with the centralized copyright determination, the copyright determination on the block chain is jointly supervised and protected by all nodes. The tampering and alteration of digital copyright requires the consent of all nodes in the network. This not only makes the cost of digital copyright infringement extremely high, but also leads to the characteristics of "untampered and verifiable" block chain.

In verifiability, block chains are often used as "true random numbers". So far, most of the true random numbers are collecting atmospheric noise, and there are still some foreign websites selling random numbers of atmospheric noise. These companies claim to sell true random numbers, not random numbers collected through atmospheric noise from antennas.

For such a string of 010101 random numbers, users have no way to verify whether it is a true random number, but can only trust the company not to do evil. Wu Yiqun, founder of TASchain, also stressed at the "Cloud Congress"

As of today, it takes at least two machines and three steps to generate a true random number, which can no longer be optimized.

On the block chain, what is often mentioned is the "hash value". The hash value is a verifiable random number, and if the plaintext of the originally generated hash value is provided, others can immediately verify the reliability of the hash.

Through these features, blockchain technology can solve the trust problem of strangers.

In the face of the "unfairness and opacity" that digital copyright is widely criticized, blockchain can make more people, including music producers, aware of the rights of works, changes and so on. On the other hand, the chain confirmation cost of the block chain is low, which can save a lot of manpower, material resources and operating costs. At the same time, it broadcasts to all nodes efficiently, almost instantly, which further simplifies the process of offline copyright confirmation.

* * copyright trading in "Smart contract" * *

After completing the confirmation of digital copyright, the final direction is still the transaction of copyright.

In the blockchain, users can buy the copyright works they need by placing a series of smart contracts, which are set to automatically pay directly to the copyright owner. Once a user shares the content with others, the paid income generated by this sharing behavior will also be distributed by a corresponding smart contract.

Through intelligent contracts, copyright trading can form a good closed loop, avoid the possible disadvantages of third-party participation, ensure the fairness and transparency of digital copyright transactions, and change the weak "cut" situation of content producers in the past.

In fact, the confusion of this situation is caused by the market, copyright dealers, online music service platform is very difficult to ensure that royalties can be paid to the right object with an appropriate amount. In traditional copyright trading, a work is often sold separately, and the trading time and platform are not the same.

Through the blockchain technology, the transaction information generated when buying and selling copyright is packaged into a new block, and the transaction data is broadcast to all blocks at the same level.

At present, in the field of online literature, "color palettes" are commonly used to determine whether writers are plagiarized or not. The so-called "color palette" is to compare the suspected plagiarism text and mark the same content with the same background color.

In the block chain, because from the very beginning, it effectively records all the process information of the content producer from the beginning to the completion of the work. Once infringement occurs, it can be tracked at the first time and at the lowest cost, reduce the input-output ratio of copyright protection, and protect the basic rights and interests of originators and right holders.

Similarly, on the topic of safeguarding rights, Wu Yiqun, founder of TASchain, also mentioned it in the "Ali Music Special performance of Yunqi Conference".

In the way of block chain, the whole set of process or contract system is solidified electronically in the block chain system from the very beginning. If either party breaches the contract, as long as enough evidence is provided, it will be carried out automatically in accordance with the process. In this way, the cost of reverse flow is greatly reduced.

On the one hand, it protects all the copyright of the content producers, on the other hand, it makes the transaction between the online music service platform and the copyright parties more fair and transparent. At present, it seems that there is still a lot of room for imagination in the marriage of blockchain and digital copyright.
