Description

Technical Field

[0001] This invention relates to the field of blockchain technology, and in particular to a method and apparatus for storing digital copyrights based on blockchain. Background Technology

[0002] Currently, the solutions used for storing digital rights in blockchain include: blockchain smart contracts and block-level layered storage.

[0003] Firstly, a blockchain smart contract (application number CN202211735702.5) was used to store digital copyrights. The hash value of the digital copyright was stored in the blockchain system, while the specific information of the digital copyright was stored in the IPFS system. The blockchain copyright was then manipulated through the smart contract. However, using a smart contract requires a transaction fee for each operation on the copyright, and due to the throughput limitations of public blockchains, the efficiency of putting digital copyrights on the blockchain and processing them is low.

[0004] Secondly, a layered storage method using the block body (application number CN201811405357.2) is used, dividing the block body into a two-layer structure. The inner layer maintains the original data structure, while the outer layer is used to store copyright data. However, this method has several drawbacks. First, it does not fully utilize the blockchain's storage space, with a significant amount of storage still being used for blockchain cryptocurrency transactions. Second, it cannot quickly locate the copyright holder. Third, it cannot destroy or facilitate copyright transactions.

[0005] Therefore, it is necessary to provide a novel blockchain-based digital copyright storage method and device to overcome the above-mentioned shortcomings. Summary of the Invention

[0006] The purpose of this invention is to provide a novel blockchain-based digital copyright storage method and device, which improves the processing efficiency of copyright transactions and increases the effective proportion of copyright data.

[0007] To achieve the above objectives, the present invention provides a blockchain-based digital copyright storage method, comprising:

[0008] Build a digital copyright alliance chain and create unspent digital copyright assets owned by users using an unspent transaction output model;

[0009] The consortium blockchain calculates the similarity of the target data provided by the user, generates the corresponding digital copyright and sends it to the user for signing, sends the signed digital copyright to the full node to create the output, places it in the coinbase transaction, and packages the transaction into a block and sends it to the consortium blockchain network.

[0010] Users view the target copyright and create a transaction. The full node verifies the legality of the transaction and sends it to the blockchain network to reach consensus.

[0011] The present invention also provides a blockchain-based digital rights storage device, the device comprising:

[0012] A blockchain database is used to store digital assets and transaction data related to the operation of digital assets;

[0013] A blockchain network, based on a consortium blockchain network structure, is where full nodes are responsible for receiving transactions from unspent assets created by users and packaging these transactions into blocks to publish them to the blockchain network.

[0014] Users, as the entities owning digital copyrights, create digital copyright on-chain transactions to put digital copyrights on the blockchain; create digital copyright transfer transactions to transfer digital copyrights; and create digital copyright destruction transactions to destroy digital copyrights.

[0015] The present invention also provides a computer-readable storage medium storing a computer program, which, when executed by a processor, implements the steps of the blockchain-based digital rights management storage method.

[0016] The present invention also provides a computer terminal, including a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the computer program to implement the steps of the blockchain-based digital rights storage method.

[0017] Compared with related technologies, this invention stores and manages digital copyrights as unspent assets of users through an unspent transaction output model, and protects existing copyrights through similarity calculation; it allows users to directly correspond one-to-one with digital copyrights, improving the targeting efficiency, retrieval efficiency, and user satisfaction of digital copyrights; it enables simple and effective on-chaining, transfer, and destruction of digital copyrights, improving the flexibility of using digital copyrights; and it enhances the security of digital copyrights by using blockchain technology to ensure the openness and trustworthiness of on-chaining.

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figure 1 This invention designs a blockchain-based digital copyright storage system that can ensure the trusted uploading, transfer, and anti-copying of users' digital copyrights. It utilizes transaction creation to upload digital copyright data to the blockchain and destroy digital copyrights, thereby improving the flexibility of digital copyright operations and reducing the cost of digital copyright operations.

[0030] S1. Construct a digital copyright alliance chain and create unspent digital copyright assets owned by users using the unspent transaction output model.

[0031] Please see Figure 2This is the blockchain transaction model involved in this invention. Structurally, it is similar to the unspent transaction model. The difference is that in this structure, the Value in the OUTPUT is used to store digital copyright, while the source data related to the copyright is stored by a third party. The Output Script is used to lock the copyright stored in the Value. The Output Script also represents the copyright owner and a specific user; only this user can manipulate this copyright.

[0032] S2. The consortium blockchain calculates the similarity of the target data provided by the user, generates the corresponding digital copyright, and sends it to the user for signing. The signed digital copyright is then sent to the full node to create the output and placed in the coinbase transaction. The transaction is packaged into a block and sent to the consortium blockchain network.

[0033] Digital copyright on the blockchain, such as Figure 3 and Figure 4 As shown. Figure 3 This is the transaction model for on-chain digital copyright registration according to the present invention. The transaction type is a coinbase transaction, so the input does not specify the transaction output for spending. The Value in the output is the on-chain digital asset, and the Output Script is the locking script for the current output, which specifies the owner of the current output Value.

[0034] Please see Figure 4 The process for storing digital copyrights on the blockchain is as follows: Users log in to the system, generate public and private keys, sign the target data using their private key, and then submit the data to the system for similarity calculation. If the similarity is too high, the user is notified that the data may infringe on copyrights; otherwise, a corresponding digital copyright is generated based on the data and sent to the user. The user signs the digital copyright and sends the signed digital copyright to a full node. The full node creates an output based on the sender's public key and copyright information, places it in a coinbase transaction, packages the transaction into a block, and when it's the node's turn to send a block, it sends the block to the blockchain network, reaches consensus, and the on-chain storage process is complete.

[0035] S3: Users view the target copyright and create a transaction. The full node verifies the legality of the transaction and sends it to the blockchain network to reach consensus.

[0036] Digital copyright transfer transaction models such as Figure 5 and Figure 6 . Figure 5This invention illustrates a digital rights transfer transaction model. In INPUT, Txid represents the Txid of the transaction containing the target copyright, Vout represents the target digital rights, and Input Script represents the unlocking script (indicating that the sender has the right to process the copyright). In OUTPUT, Value represents the target copyright, and OutputScript represents the locking script (indicating that the copyright belongs to the recipient).

[0037] Please see Figure 6 This demonstrates the digital copyright transfer transaction process. Users check if they own the target copyright; if so, a transfer transaction is created, requiring the user to enter their wallet password, target address, and target digital copyright. The complete transaction is then sent to a full node, which verifies its legitimacy. After successful verification, the transaction is packaged and sent to the blockchain network when it's the node's turn to send the transaction. Once consensus is reached, the transfer is complete.

[0038] Digital copyright destruction, such as Figure 7 and Figure 8 . Figure 7 This demonstrates a transaction model for digital rights to be destroyed (DLOD). INPUT represents the Txid, location, and unlocking script of the transaction containing the target DLOD to be destroyed, similar to DLOD transfer. OUTPUT's Value represents the target DLOD. Unlike other transactions, the Output Script for this transaction begins with a RETURN field (represented as hexadecimal 0x6a in the script), followed by 80 bytes of explanatory information.

[0039] Figure 8 The process of destroying digital rights to copyright (DRP) is demonstrated. Users check if the DRP they want to destroy exists. If it does, a destruction transaction is created by entering the user's wallet password, the target DRP, and a description of less than 80 bytes. The transaction is then sent to a full node. After verifying the transaction's validity, the full node packages it. When it's the node's turn to send a block, the target block is added to the blockchain.

[0040] This invention proposes an unspent transaction output model that stores digital copyright data, allowing digital copyrights to be directly stored in the blockchain system, enabling users to directly correspond one-to-one with digital copyrights, thereby improving the efficiency of digital copyright targeting.

[0041] This invention establishes a transaction structure through an unspent transaction output model, including transaction models for copyright data on-chain transactions, copyright transfer transactions, and copyright destruction transactions.

[0042] This invention, through a consortium blockchain structure and a transaction model, allows data to be easily uploaded to the blockchain without requiring high transaction fees.

[0043] The blockchain-based digital copyright storage method designed in this invention includes methods for querying digital copyrights, putting digital copyrights on the blockchain, transferring digital copyrights, destroying digital copyrights, and preventing counterfeiting and confirming digital copyrights, which can bring benefits to digital copyright processing.

[0044] 1. It can efficiently store digital copyrights and protect existing copyrights through similarity calculations.

[0045] 2. Blockchain technology is used to ensure the openness and trustworthiness of digital copyright registration on the chain. Furthermore, each digital copyright is signed with the user's private key, ensuring the secure registration of digital copyrights on the chain and preventing illegal theft.

[0046] 3. It can match digital copyrights with users one-to-one, improving the efficiency of digital copyright retrieval and increasing user satisfaction.

[0047] 4. This invention enables the simple and effective uploading, transfer, and destruction of digital copyrights on the blockchain, improving the flexibility of using digital copyrights.

[0048] 5. Compared with public blockchain projects, this invention greatly improves data throughput and reduces the waiting time for users to store digital copyrights.

[0049] Figure 9 This is the system operating model of the present invention. This model mainly involves three parties: a blockchain database, a blockchain network, and users. The blockchain database is used to store digital assets and transaction data related to the operation of digital assets. The blockchain network uses a consortium blockchain model, which can greatly improve transaction throughput. Full nodes in the blockchain network layer are responsible for receiving transactions created by users, packaging these transactions into blocks, and publishing them to the blockchain network. Users are the main group operating digital copyrights. Core operations include querying the digital copyrights (account assets) owned by an account, creating digital copyright on-chain transactions to put digital copyrights on the blockchain, creating digital copyright transfer transactions to transfer digital copyrights, and creating digital copyright destruction transactions to destroy digital copyrights.

[0050] Compared to related technologies, this invention addresses the low efficiency of digital copyright processing by proposing a dedicated blockchain system for handling digital copyrights. Copyrights are treated as assets for blockchain users, who can view their owned copyrights by querying their "balance" and transfer them through transactions. This approach, treating copyrights as blockchain assets, solves the problem of reduced blockchain processing efficiency caused by additional functions (such as public chain expansion capabilities), thus improving the efficiency of digital copyright processing. Regarding copyright storage, this invention proposes replacing the Value in the unspent transaction output model with copyright data, and then creating a transaction model specifically for processing this unspent transaction output. This transaction model is dedicated to processing copyright data, increasing the proportion of copyright data in the overall transaction data volume and improving the effective proportion of locally stored data.
