Description
Technical Field
The invention relates to the field of digital publishing protection, in particular to a digital copyright protection method based on a block chain technology.
Background
At present, the intellectual property industry has more pain points, which are divided according to a longitudinal industry chain and can be mainly summarized into three major aspects.
First, copyright registration is difficult and timeliness is poor.
Under the internet era, whether the network is written works or music, pictures, videos, VR and games, the number of excellent network original works is huge and the transmission speed is astonishing. However, the registration speed of copyright bureau is far inferior to the speed of traffic on network, because the traditional copyright registration needs to be registered in a centralized mechanism or platform, the period is long, and the digital file product is easy to copy. Therefore, the method is not in line with the habit and the characteristic of registering the copyright of a huge original individual, and the offline registration form is not matched with the development speed of the mobile internet era. Such as musical works, the market is not straightforward to identify the owner of the copyright of the song. Ownership may have gone through many different user turnovers, or there may be different versions of songs, each with a different owner. There may be many rights in a song, including rights to the composition and recording and rights to the performer, which do not always have the same owner. In fact, publishing companies sometimes have to hire experts that specialize in tracking music specific copyright holders, which shows the complexity of copyright validation. At present, the efficiency of the copyright validation industry is improved by a lot under the drive of Internet enterprises.
Secondly, the right use is difficult to appear, and the transaction of copyright works is difficult.
At present, the intellectual property industry has serious imbalance of supply and demand, and more is reflected in that supply and demand cannot be matched. The trading of copyrighted works is difficult, works of copyright owners cannot be presented in time, purchasers of copyrighted works cannot purchase excellent works in time, and the creation of a channel for the value of intellectual achievements is blocked. In 2017, the total amount of the national copyright (copyright) registration reaches 2747652 pieces, wherein 2001966 pieces of works registration, 745387 pieces of computer software copyright registration and 299 pieces of copyright registration are 36.86 percent higher than 2007698 pieces in 2016. In the face of such huge and rapidly growing copyright supply, the intellectual property industry should consider how to match supply and demand so as to promote self healthy growth. In fact, infringers have sufficient ways to bypass or ignore the traditional third-party authentication channels, but the authors cannot effectively limit and attack the infringers, and the use of the own works by the authors is greatly limited. In an emerging digital copyright era, how to effectively solve the problem of copyright protection and facilitate copyright transaction and popularization really needs a breakthrough method.
Thirdly, the infringement is easy and the right is difficult to be maintained
The rapidity of the digital era and the easy copying property of the works make the internet copyright management increasingly difficult, and the cost of piracy infringement is greatly reduced, which causes great loss to copyright owners and the whole copyright industry. From the right maintaining link, the tracing chain is longer. First, it is difficult to define the infringement, and the infringement needs to be finally determined by checking the authorization description stage by stage. Especially for digital content such as sound and images, it is easier to cause a dispute for ownership. This is also a hindrance to the spread of digital rights because it is difficult to distinguish between "original edition" and "imitation". Secondly, the right is difficult to trace back, and after the infringement is determined, the right is difficult to trace back to the source. Taking music copyright as an example, the person of the word song has the copyright of the word song, and the singer has the copyright of the song, and a series of rights such as copy right, distribution right, playing right, showing right are crossed, and the complexity of the rights attribution is conceivable. Finally, the phenomenon of copyright violation in history in China is serious, and it is very common to download pirated music and not mark reference sources, which greatly hinders the healthy development of the content market.
The block chain technology enables the copyright works to be registered to realize self-supervision, the centralization is achieved, the management cost is greatly reduced, and the safety of a registration database is improved. Firstly, theoretically, due to the characteristic of decentralized block chain, the method for registering the copyright works does not need authentication and management of a third party in the future, avoids the long process of authorization of a traditional organization, is directly supervised by the whole network, and greatly saves the cost of copyright owners, the management cost of the management and the management cost of a registration organization. Because the blockchain technology has the unchangeable specific, the copyright works do not need various authentication materials to prove the originality of the copyright works, and the blockchain technology can prove the works. Meanwhile, due to the structural characteristics of the block chain, the registration information of any original work is unique, and the unique timestamp record exists no matter the content information or the creation time of the work. This provides a solution for the definitive right of copyrighted works. And each node of the block chain is provided with a copy of the registered work information, so that the integrity of the work is guaranteed and the work is easy to track, therefore, the operation of other nodes cannot be influenced when one node is invaded or damaged in the method, and the real-time monitoring of the whole network can be completed. On one hand, the copyright infringement cost can be greatly improved; on the other hand, the infringement is monitored more timely, and a foundation is provided for real-time right maintenance. The block chain technology can create a new protection system in the aspects of copyright registration, right confirmation and right maintenance.

The invention utilizes P2P network, encryption signature technology, block chain, common identification mechanism and other core contents, and uses database to construct a block chain-based copyright protection method. Copyright attribution, copyright usage and copyright maintenance of the digital knowledge content are made possible.

The concrete practical operation is as follows:
the method comprises the steps of firstly, establishing a block chain structure which comprises a core layer, an expansion layer and an application layer, wherein the core layer is designed, the core layer operates by referring to a bitcoin bottom layer block chain network, a network environment is established, a transaction mode is established, and transaction and reward rules are formulated. And provides file creation, data sharing, copyright registration, work transaction and transfer functions to the expansion layer and the application layer through the programmable interfaces. According to the method, various operations of the user are designed through the concept of transaction, the transaction initiated by the user is processed in a digital currency circulation mode, and the result that the storage of a certain block is consistent among a plurality of nodes in a block chain network is guaranteed through determining the accounting node based on an authorized equity mechanism.
Method module construction flow diagram as shown in fig. 2, the P2P network module completes node initialization, so that any node can access each other; the encryption verification module generates an encrypted hash address, expands and associates other functions, and simultaneously provides functions of inquiring to be traded, inquiring an associated account number, signing a transaction by a user and creating a multi-signature account number; the user address module is used for managing user accounts, providing data support for user operation, and performing user authority authentication, recording and managing various operations related to users. The user address is a public key address, is generated by the password component in the step three, and has anonymity. Meanwhile, the user address can be used as an account in transaction; the transaction module is the most important part of the method, is a core function in a block chain product, and generates transaction information in a period of time into blocks to realize electronic book copyright registration and copyright transaction; the block chain storage module is used for carrying out block storage and comprises a loading block chain, a synchronous block chain and a new processing block chain; the consensus mechanism module makes each node in the block chain network agree on the selection of the node with the block accounting right of this time, and writes the block generated in the step five into the node block chain storage module
Step two, establishing a P2P network based on a block chain technology copyright protection method, and providing an initial node list; the nodes are guaranteed to have cross-domain access capability, and the nodes can be freely accessed; the node has updating capability, and the smoothness of the network is ensured. Specifically, firstly, a routing expansion function is provided, and node requests are quickly processed and used for inquiring nodes and information thereof; and in the node storage process, firstly initializing the node for networking use, then carrying out persistence on the node information, storing the node information into a database, writing the configured nodes into the database in sequence when the block chain loading is finished, ignoring the node if the same node exists in the database, then updating a node list, and finally starting to update a node event.
And step three, designing a block chain technology-based copyright protection method encryption verification module. The functions provided by the module comprise a to-be-transacted query, an associated account list query, a user signature transaction and a signature account creation. Using SHA256 hash algorithm to encrypt and generate hash value, and generating corresponding key pair through Ed25519 component; the authentication process uses the Ed25519 component, which is a digital signature algorithm. The signature process does not depend on a random number generator, the problem of time channel attack does not exist, and both the signature and the public key are very small. In practice, a secret key and a public key are generated from a password set by a user, the public key is converted into a user address through a 16-system character string, and the user address is input during transaction.
And step four, constructing a block chain technology-based copyright protection method user address module. The module is used for managing user accounts, providing data support for user operation, authenticating user authority, and recording and managing various operations related to users. The user address is a public key address, is generated by the password component in the step three, and has anonymity. Meanwhile, the user address can be used as a payment address, and payment can be directly made for the user name of the user. This module corresponds to two basic functions, firstly user account management and secondly expansion and association of other functions by the transaction module.
And step five, designing a block chain technology-based copyright protection method transaction module. The method is a process of generating blocks of transaction data and storing the blocks into a block chain by using a block chain network to realize user-related operations in a mode of underlying digital money transfer. The transaction module based on the block chain technology copyright protection method ensures that transactions are generated correctly, propagated and verified quickly, and are finally written into the block chain data storage module. A transaction includes the following processes: (1) transaction data is generated. (2) Signing the legal transaction. (3) And verifying the validity of the transaction. (4) Broadcast to the blockchain network. Further, step (1) generates transaction data, wherein the transaction data comprises the following information; transaction type, payment account number; receiving an account number; the number of transactions. It is necessary to verify the presence of the user initiating the transaction, the correctness of the key, the presence of multiple signed account numbers, the presence of the payment password, and the validity of the recipient user address. And (2) signing a legal transaction. If the transaction information is all correct, a legal transaction is carried out, and public key signatures of both transaction parties are used to ensure that the transaction belongs to. Meanwhile, the transaction timestamp of the transaction is also required to be accurately recorded, so that the transaction can be traced conveniently. Transaction IDs are also generated and each transaction I D contains rich encryption information. And (3) verifying the validity of the transaction, wherein the transaction is generally considered to be unchangeable after 6-10 blocks of verification are carried out on the transaction. The transaction validity here mainly means that the transaction is not confirmed, or is not a transaction repeatedly submitted by the user, namely a double-flower transaction, except that the basic information is correct. Each transaction must be validated before being broadcast to the network and illegal transactions have no opportunity to be broadcast to the network. The validated transaction can be added directly to the blockchain, from the first of step five to where the method is done at one node. Once the transaction is broadcast to the network, the authentication and processing process is repeated at other nodes. And (4) broadcasting to a point-to-point network, and writing the transaction data generation block into the block chain storage module by means of the point-to-point network, so that the transaction data cannot be tampered, and the query and the trace can be easily performed. On a centralized server, the transaction records are ensured to be traceable, more technical means are adopted, more data fields are recorded, and the large data redundancy is kept, so that more capital cost is paid.
And step six, designing a block chain storage module of the copyright protection method based on the block chain technology. A blockchain is understood from a database design perspective, and is a "self-referencing" database table. Each record represents a block, the block stores transaction data in a period of time, the block records the information of a record before the block, and the previous record can be directly inquired, so that the records can be sequentially traced from any record to the first record. The common self-reference table structure usually uses a transaction ID as a related foreign key, and transaction data is an information field subjected to encryption processing, has a signature authentication effect, can realize self-verification and prevents tampering. Another important table directly associated with the blockchain is the transaction table. The transaction module contains a plurality of transactions that are stored in a separate table and that form a many-to-one association with the blockchain. Once a block is traced back, the transaction records contained in the block can be queried. An account book which is transparent, cannot be tampered and is convenient to trace is formed. Specifically, the design process includes the steps of (1) storing a created block, wherein the created block is hard coded into a program and can be directly written into a database when the program initially runs, and each client side is guaranteed to have a credible and safe root block. And (3) loading the local blocks in the step (2), wherein each node needs to firstly load and verify a local block chain to ensure that the local block chain is not tampered, and the process is carried out in the process of software initialization. And (3) loading the blocks one by one and verifying the blocks. In this step, the previous block is traced back first; then verifying the signature of the block to prevent the content of the block from being tampered, and if the verification fails, terminating the whole verification process and deleting the block and the blocks behind the block; the block period is re-verified to prevent the block location from being tampered with. And finally, verifying the transaction data, wherein the specific flow is the same as the step four. Step (4) create a new tile, acquire the unconfirmed transaction, and re-validate, and provide the tile with a key pair and a timestamp by acquiring the tile period data. In this step, a list of trustees for the production block is first obtained, and then a corresponding key pair is found based on the current time period information, the key being associated with a particular trustee for a particular time period. Step (5) generates block chain forking. And (6) synchronizing the block chains and solving the bifurcation. Three operations are performed in this process: sync block, verify if it is an unconfirmed transaction and signature.
And seventhly, designing a consensus mechanism of the copyright protection method based on the block chain technology. All nodes in the block chain are operated cooperatively, and the node behaviors can be managed in a unified mode. Based on an authorized equity certification mechanism, a block is created by a trustee, the trustee is from a common user node, registration is needed firstly, then the trustee is promoted by the trustee, community trust and voting are sought, and the trustee can be accepted as a node which can really process the block and obtain a coin reward only when enough lines are obtained until the first 101 names are obtained. The authorized equity proving mechanism votes through the equity proportion, and by absorbing the strength of community nodes, the nodes vote to select relatively reliable nodes for the maximization of self interests, so that the security is higher and the decentralization is realized. The whole mechanism needs to complete the following processes: (1) the user registers the trustee and accepts the vote, and the number of the votes is 101 before the line arrangement; (2) maintaining circulation and adjusting the person in support; (3) and circularly generating a new block and broadcasting the new block to the whole network.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, and all modifications and equivalents of the present invention, which are made by the contents of the present specification and the accompanying drawings, or directly/indirectly applied to other related technical fields, are included in the scope of the present invention.
