Best Mode of Carrying Out the Invention

It can be understood that this application involves blockchain technology and its smart contract related technologies. Blockchain technology is the technical basis for realizing distributed applications. Blockchain technology uses hash pointers instead of traditional pointers and stores digital asset transactions in the block body. It is a transaction-driven state machine. Among them, smart contract refers to a piece of status code running on the blockchain system. The code logic defines the content of the contract. It is a special protocol that is used when formulating contracts in the blockchain and contains code functions (Function). , and can also interact with other contracts, make decisions, store data and other functions. Smart contracts provide verification and execution of the conditions specified in the contract. Smart contracts allow trusted transactions to be made without third parties, which are traceable and irreversible.

Please refer to Figure 1. Figure 1 is a schematic structural diagram of a blockchain-based code copyright registration system provided by an embodiment of the present application.

As shown in Figure 1, the network architecture may include a blockchain network 10 and a terminal 20. Among them, the blockchain network 10 may include multiple blockchain nodes. The logic code of the smart contract runs in the blockchain nodes. The multiple blockchain nodes can interact with each other in data. The multiple blocks The link node may include n nodes such as node N1, node N2,... and node Nn. The terminal 20 may include n client nodes such as node C1, node C2, ... and node Cn.

It must be noted that the client nodes included in the terminal 20 are also nodes in the blockchain. The nodes in the blockchain network 10 are usually full nodes, and the nodes in the terminal 20 are usually light nodes. For ease of understanding, all nodes in the blockchain are divided into blockchain network 10 and terminal 20. Full nodes save all the contents of the entire block, while light nodes only save the header information of the block. For mobile portable devices, if all the contents of the block are stored, the space required is too large, which is unrealistic. Therefore, the light node only needs to store the block header information, and the full node stores all the contents of the block. When it is necessary to prove to the light node whether a transaction has been written to the blockchain network 10, Merkle Proof can be used to go from the transaction to the root. A path of a node is Merkle Proof, also known as Merkle Path. The full node sends the entire Merkle Proof to the light node. The light node can calculate the root hash value based on it and compare it with its own saved one to verify whether the transaction has been written. into the blockchain. As long as all hashes along this path are correct, the content has not been modified.

Furthermore, a blockchain node in the blockchain network 10 or a node in the terminal 20 can be composed of a server or a terminal device. Among them, the server used to constitute the 10 nodes of the blockchain network can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or it can provide cloud services, cloud databases, cloud computing, cloud Cloud servers for basic cloud computing services such as functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN, and big data and artificial intelligence platforms. The server used to form the terminal node 20 is usually a terminal device, and the terminal device can be: a smart terminal such as a smart phone, a tablet computer, a notebook computer, or a desktop computer.

It is understandable that since software systems often contain a large number of code documents, it is almost impossible for the existing centralized code copyright registration system to verify the originality of each document. Secondly, due to the ambiguity of copyright ownership and the lack of a unified code version management platform, copyright transactions are not smooth and a code copyright market economy cannot be formed.

Please refer to Figure 2. Figure 2 is a schematic structural diagram of a blockchain-based code copyright registration system provided by an embodiment of the present application.

A code copyright registration system based on blockchain, including client 100 and blockchain platform 200, including:

The client 100 is configured to send a registration data packet to the blockchain platform 200, where the registration data packet includes a feature set, and the feature set is generated by the client 100;

Specifically, the blockchain platform 200 can obtain the registration data package sent by the client 100. The registration data package sent by the client 100 to the blockchain platform 200 mainly includes the feature set of the source code data.

Among them, the source code data can be a document containing source code data, and the feature set refers to a feature set with code arrangement characteristics obtained according to a certain algorithm operation based on the source code data.

Since the blockchain platform 200 is a decentralized and distributed platform based on smart contracts, if the client 100 directly uploads source code data to the blockchain platform 200, it will not only greatly increase the storage of each blockchain node The pressure will also cause the blockchain platform 200 to greatly increase the calculation amount, reduce the operating efficiency, and generate a large amount of gas fees, making the entire system only theoretically feasible. Therefore, pre-producing the feature set of source code data in the client 100 will greatly reduce the storage pressure and computing pressure of the blockchain platform 200 and save gas costs.

It is understandable that in smart contract technology, data calculation and storage require payment of gas fees. Therefore, it is necessary to design a generation method that can make the feature set occupy a small space, save the source code document data features, and facilitate verification of the feature set.

Client 100 is also used for:

Before sending the registration data package to the blockchain platform 200, obtain source code data and initialize the feature set;

The source code data may be uploaded to the client 100 by the user. The feature set can be a binary value with a data width of 64 bits.

Decompose the source code data into several feature vectors;

Specifically, the decomposition process of source code data can be achieved through word segmentation or bigram, and then five levels of weights, such as 1-5, are set for each feature vector.

Perform a hash operation on each feature vector to obtain a set of hash values;

Weight the hash value corresponding to each feature vector;

Specifically, each bit on the hash value is traversed. When the value on a bit is 1, the hash value and the weight value are multiplied. When the value on a bit is 0, the hash value and the weight are multiplied. Values are multiplied negatively.

Traverse the set and convert the feature set according to each hash value in the set; accumulate and merge the values of specific bits of the hash value into the corresponding bits of the feature set;

Traverse each bit of the feature set. When the value of the bit is greater than 0, the value of the corresponding bit of the feature set is set to 1; when the value of the bit is less than or equal to 0, the corresponding bit of the feature set is set to 1. The bit value is set to 0;

Please refer to Figure 3 as well. Figure 3 is a schematic diagram illustrating the feature set generation process provided by an embodiment of the present application.

As shown in Figure 3, first, the blockchain platform 200 decomposes the source code data into several feature vectors through word segmentation or bigram and gives each feature vector a certain weight. Then, it performs a hash operation on the feature vector and multiplies it by the weight value. Obtain the set of hash values h1, h2...hn, and then accumulate and merge the sets of hash values, that is, add the first value of h1, h2...hn to obtain the feature set No. The value of one digit, the value of the second digit of h1, h2...hn are added to obtain the value of the second digit of the feature set, and so on until the values of all corresponding bits are accumulated to obtain the first stage feature set. , and finally perform dimensionality reduction on the first-stage feature set, that is, if the value of a specific bit is greater than 1, it is set to 1, otherwise it is set to 0, and the final feature set can be obtained.

The above process is the feature set generation process. The feature set obtained by performing a series of operations on the source code data such as word segmentation, hashing, weighting, accumulation, and dimensionality reduction can not only save the source code document data features, but also occupy a small space, achieving The feature set is easy to store in the blockchain platform 200 and consumes less gas.

The blockchain platform 200 is used to verify the originality of the feature set; when the feature set is successfully verified, receive the feature set and perform registration services related to the feature set; when the feature set is successfully verified, When the verification of the feature set fails, the feature set will be rejected;

Specifically, after the blockchain platform 200 obtains the feature set, it can verify the originality of the feature set.

Specifically, after the originality verification is successful, the blockchain platform 200 can register the feature set as a copyright, and the smart contract in the blockchain platform 200 can write the feature set data into the storage domain. When the blockchain platform 200 When a block is generated, relevant transactions are published to the blockchain network 10 to achieve announcement and non-tampering functions.

It is understandable that in smart contract technology, computing power is a very precious resource. When verifying originality, you should avoid consuming excessive computing power on the blockchain platform. This will not only reduce the system operating efficiency, but also generate a large number of Gasoline costs.

Of course, a specific originality verification method can be designed, as detailed below:

Blockchain platform 200 is specifically used for:

Obtain a feature set set; wherein the feature set set may be the sum of all registered feature sets in the blockchain platform 200 .

Traverse the feature set collection, perform Hamming operation on the current feature set and the feature set, and obtain the Hamming distance; when the Hamming distance is less than or equal to 3, it is determined that the originality verification fails; when the Hamming distance does not exist When the Hamming distance is less than or equal to 3, it is determined that the originality verification is successful; the current feature set may be the feature set currently read when the blockchain platform 200 traverses the feature set set and compared with the feature set that needs to be registered. Among them, in information coding, the number of different bits encoded in the corresponding bits of two legal codes is called the code distance, also known as the Hamming distance.

The above process is the originality verification process. It determines whether the originality verification is successful by comparing the feature sets that need to be registered with the feature sets that have been registered in the blockchain platform 200 and calculating the Hamming distance. This method can greatly reduce the computing pressure of the blockchain platform 200 and reduce gas expenses.

It is understandable that it is unsafe to transmit traffic data in the Internet environment, and there is a risk of traffic data being tampered with. Therefore, the legality of traffic data needs to be verified, as detailed below:

The registration data package also includes a timestamp and a rights public key. The registration services specifically include:

The blockchain platform 200 performs a hash operation according to the feature set to generate a digital fingerprint; the blockchain platform 200 uses the digital fingerprint as a Key value, and publicizes the feature set, the timestamp and the rights. The key is stored in the storage domain as the Value value.

Specifically, after the originality verification is successful, the blockchain platform 200 can perform a hash operation based on the feature set to generate a digital fingerprint. The digital fingerprint is used as a unique identifier of copyright and plays a role in rapid retrieval. In addition, due to the hash Anti-collision characteristics can clarify the ownership of rights.

Specifically, the blockchain platform 200 can also use the timestamp in the registration data package as the copyright application date, and use the rights public key as an identifier of the rights holder. The rights public key can be the public key address of the client 100, or it can It is the public key address of the right holder entered by the user.

Further, the blockchain platform 200 can store the above data in the storage domain of the smart contract in the form of HashMap, and can use the digital fingerprint as the Key value, and the feature set, timestamp and rights public key as the Value value to facilitate quick search. .

The above process is the copyright registration process. A digital fingerprint is generated based on the feature set as the unique identifier of copyright, which can quickly index and clarify rights.

The client 100 is also used to send a change data package to the blockchain platform 200; the change data package is generated by the client 100; the change data package includes the registration voucher and the first digital signature;

Specifically, after the blockchain platform 200 obtains the change data package, it can obtain the registration certificate and the first digital signature, and then verify the legality of the change data package based on the registration certificate and the first digital signature.

The registration voucher is used to record information related to the change business, and the first digital signature can be obtained by the copyright owner using the private key to sign the registration voucher.

The blockchain platform 200 is also used to perform signature verification on the change data package; when the verification of the change data package is successful, execute the change business related to the registration certificate; when the change data package is successfully verified, When verification fails, the change data packet will be rejected;

Specifically, after the blockchain platform 200 obtains the change data package, it can read the registration voucher and the first digital signature contained in the change data package, and then perform signature verification on the registration voucher.

Specifically, the registration certificate may include the digital fingerprint of the copyright that needs to be changed. The blockchain platform 200 can obtain the corresponding rights public key based on the digital fingerprint. The blockchain platform 200 will then use the rights public key to decrypt the first digital signature. The data obtained is then compared with the registration voucher, and when the two match, the signature verification is successful.

Specifically, the registration certificate also includes the target public key, which is the public key address of the copyright assignee. After successful signature verification, the blockchain platform 200 can modify the rights address corresponding to the digital fingerprint to the target public key value.

The above process is the signature verification and change business process. By setting up signature verification, the authenticity of the change business can be guaranteed. Malicious nodes cannot pass the verification without obtaining the private key corresponding to the right public key, thus ensuring the security of the system.

It is understandable that due to the irreversibility of operations in blockchain technology, and at the same time, the registration voucher is generated unilaterally by the right holder. If the copyright changes are carried out by the two parties, the process of generating the registration voucher may be changed by the right holder. The target public key is incorrectly recorded, resulting in the transferee being unable to obtain the copyright.

Therefore, a specific method for copyright changes to be confirmed by both parties can be specifically designed, as detailed below:

The change data package also includes a second digital signature. The registration certificate includes the target public key and the digital fingerprint. The signature verification specifically includes:

The blockchain platform 200 performs verification based on the rights public key, the registration certificate and the first digital signature;

The blockchain platform 200 performs verification based on the target public key, the registration certificate and the second digital signature;

The second digital signature may be obtained by the copyright transferee using the transferee's private key to sign the registration certificate, and the transferee's private key and the target public key are combined into a public-private key pair.

Specifically, the blockchain platform 200 can obtain the corresponding rights public key based on the digital fingerprint. The blockchain platform 200 will then use the rights public key to decrypt the first digital signature to compare the data with the registration certificate. When the two match Signature verification is successful.

Further, the blockchain platform 200 can obtain the target public key based on the registration voucher. The blockchain platform 200 will then use the target public key to decrypt the second digital signature and compare the data obtained with the registration voucher. When the two match, the signature Verification successful.

Further, after both signature verifications pass, the blockchain platform 200 can perform the change business associated with the registration certificate.

In the above process, the registration certificate is generated after confirmation by both the right holder and the transferee. Before executing the change business, the signature information of both parties needs to be confirmed to ensure the accuracy of the transferee.

It is understandable that symmetric encryption involves the management of symmetric keys, especially the distribution of symmetric keys. It requires the communicating parties to exchange a shared symmetric key through another secure channel before communicating in order to be safe. The ciphertext is transmitted through unsecured channels; once the symmetric key is stolen, the encryption will be immediately invalid.

Therefore, a method for transmitting symmetric keys using asymmetric encryption in an Internet environment can be specifically designed, as detailed below:

Change business, specifically including:

The blockchain platform 200 obtains the corresponding rights public key according to the digital fingerprint search; replaces the value of the rights public key with the value of the target public key.

During the above process, the blockchain platform 200 quickly locates the rights public key through the digital fingerprint in the registration certificate, thereby realizing the system's rapid change of the copyright owner.

The following takes the data interaction between the client 100 and the blockchain platform 200 as an example to perform a detailed description of the embodiments of this application.

Please refer to Figure 4 as well. Figure 4 is a schematic diagram of a data interaction process scenario between a client 100 and a blockchain platform 200 provided by an embodiment of the present application.

S405. The client 100 sends a change data packet to the blockchain platform 200;
