[0002] With the development of Internet technology, more and more software systems are being developed and applied to production and life. At the same time, the problem of software code copyright management has become increasingly prominent. First, software systems often contain a large number of code documents. It takes a lot of manpower and material resources to determine the originality of code documents, which makes it difficult to register the copyright of software codes. Secondly, the lack of a unified code copyright management platform has led to the dispersion of copyright resources and the ambiguity of copyright ownership, which is not conducive to copyright transactions and the formation of a market economy.

[0003] At present, the copyright resources of code documents are scattered and the ownership is unclear, which leads to the prominent problems of code theft and infringement of the rights of the original author, which has attracted widespread attention from scholars in many fields.

[0042] It is understandable that the present application relates to 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 transactions of digital assets in the block body. It is a transaction-driven state machine. Among them, a smart contract refers to a state code running on a blockchain system. The code logic defines the content of the contract. It is a special protocol used when formulating a contract in a blockchain. It 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 established in the contract. Smart contracts allow trusted transactions without a third party, and these transactions are traceable and irreversible.

[0043] See also Figure 1 , Figure 1 This is a structural diagram of a blockchain-based code copyright registration system provided in one embodiment of the present application.

[0044] like Figure 1 As shown, the network architecture may include a blockchain network 10 and a terminal 20. 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 may interact with each other, and the multiple blockchain nodes 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.

[0045] It must be noted that the client node included in the terminal 20 is also a node 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 the blockchain network 10 and the terminal 20. The full node saves all the contents of the entire block, while the light node only saves the block header information of the block. For mobile portable devices, if all the contents of the block are stored, the required space is too large, which is unrealistic. Therefore, the light node only needs to store the block header information, and the full node can store all the contents of the block. When it is necessary to prove to the light node whether a transaction is written into the blockchain network 10, Merkle Proof can be used. A path from the transaction to the root node is Merkle Proof, also known as Merkle Path. The full node sends the entire Merkle Proof to the light node, and the light node can calculate the root hash value based on it and compare it with the one it saves, thereby verifying whether the transaction is written into the blockchain. As long as all hash values ​​are correct along the path, it means that the content has not been modified.

[0046] Furthermore, a blockchain node in the blockchain network 10 or a node in the terminal 20 may be composed of a server or a terminal device. The server used to constitute the node of the blockchain network 10 may be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud 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 constitute the node of the terminal 20 is usually a terminal device, which may be a smart terminal such as a smartphone, a tablet computer, a laptop computer, or a desktop computer.

[0047] 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.

[0048] See also Figure 2 , Figure 2 This is a structural diagram of a blockchain-based code copyright registration system provided in one embodiment of the present application.

[0049] A code copyright registration system based on blockchain includes a client 100 and a blockchain platform 200, wherein:

[0050] The client 100 is used to send a registration data packet to the blockchain platform 200, wherein the registration data packet includes a feature set, and the feature set is generated by the client 100;

[0051] Specifically, the blockchain platform 200 can obtain the registration data packet sent by the client 100. The registration data packet sent by the client 100 to the blockchain platform 200 mainly includes a feature set of source code data.

[0052] The source code data may be a document containing the source code data, and the feature set refers to a feature set having code arrangement features obtained by calculating the source code data according to a certain algorithm.

[0053] Since the blockchain platform 200 is a decentralized and distributed platform based on smart contracts, if the client 100 directly uploads the source code data to the blockchain platform 200, it will not only greatly increase the storage pressure of each blockchain node, but also cause the calculation amount of the blockchain platform 200 to increase greatly, reduce the operating efficiency, and generate a large amount of gas fees, making the entire system only theoretically feasible. Therefore, generating a feature set of source code data in the client 100 in advance will greatly reduce the storage pressure and calculation pressure of the blockchain platform 200 and save gas fees.

[0054] It is understandable that in smart contract technology, data calculation and storage require gas fees. Therefore, it is necessary to design a method that can not only make the feature set occupy less space, but also preserve the source code document data features and facilitate the verification of the feature set generation method.

[0055] The client 100 is also used for:

[0056] Before sending a registration data packet to the blockchain platform 200, obtaining source code data and initializing the feature set;

[0057] The source code data may be uploaded by a user to the client 100. The feature set may be a binary value with a data width of 64 bits.

[0058] Decomposing the source code data into a plurality of feature vectors;

[0059] Specifically, the decomposition process of the source code data can be achieved through word segmentation or bigram, and then a weight of 1-5 is set for each feature vector.

[0060] Performing a hash operation on each of the feature vectors to obtain a set of hash values;

[0061] Weighting the hash value corresponding to each of the feature vectors;

[0062] 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 positively multiplied. When the value on a bit is 0, the hash value and the weight value are negatively multiplied.

[0063] Traversing the set, converting the feature set according to each hash value in the set; accumulating and merging the value of a specific bit of the hash value to the corresponding bit of the feature set;

[0064] Traversing 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 value of the corresponding bit of the feature set is set to 0;

[0065] Please also see Figure 3 , Figure 3 It is a schematic diagram demonstrating the feature set generation process provided in one embodiment of the present application.

[0066] like Figure 3 As shown, first, the blockchain platform 200 decomposes the source code data into several feature vectors through word segmentation or bigram and assigns a certain weight to each feature vector. Then, the feature vector is hashed and multiplied by the weight value to obtain a set of hash values ​​h1, h2.......hn. The set of hash values ​​is then accumulated and merged, that is, the first-bit values ​​of h1, h2.......hn are added to obtain the first-bit value of the feature set, and the second-bit values ​​of h1, h2.......hn are added to obtain the second-bit value of the feature set, and so on until the values ​​on all corresponding bits are accumulated to obtain the first-stage feature set. Finally, dimensionality reduction is performed on the first-stage feature set, that is, the value on a specific bit is set to 1 if it is greater than 1, otherwise it is set to 0, so as to obtain the final feature set.

[0067] The above process is the feature set generation process. The feature set is obtained by performing a series of operations such as word segmentation, hashing, weighting, accumulation, and dimensionality reduction on the source code data. It can not only preserve the source code document data features, but also occupy a small space, thereby achieving the effect of easy storage of the feature set in the blockchain platform 200 and low gas consumption.

[0068] The blockchain platform 200 is used to verify the originality of the feature set; when the feature set is successfully verified, the feature set is received and the registration service related to the feature set is performed; when the feature set is failed to be verified, the feature set is rejected;

[0069] Specifically, after the blockchain platform 200 obtains the feature set, it can verify the originality of the feature set.

[0070] Specifically, after the originality verification is successful, the blockchain platform 200 can register the feature set as 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 generates a block, the relevant transaction is published to the blockchain network 10 to achieve the purpose of announcement and non-tamperability.

[0071] It is understandable that in smart contract technology, computing power is a very valuable resource. When conducting originality verification, it is necessary to avoid consuming excessive computing power of the blockchain platform, which will not only reduce the efficiency of system operation, but also generate a lot of gas fees.

[0072] Of course, a specific originality verification method can be designed, as follows:

[0073] Blockchain platform 200 is specifically used for:

[0074] Obtain a feature set set; wherein the feature set set can be the sum of all registered feature sets in the blockchain platform 200.

[0075] Traverse the feature set set, perform Hamming operation on the current feature set and the feature set to obtain the Hamming distance; when the Hamming distance is less than or equal to 3, determine that the originality verification fails; when the Hamming distance is not less than or equal to 3, determine that the originality verification succeeds; wherein, the current feature set can be the feature set read by the blockchain platform 200 when traversing the feature set set and compared with the feature set that needs to be registered. Among them, in information encoding, the number of bits encoded differently on the corresponding bits of two legal codes is called code distance, also known as Hamming distance.

[0076] The above process is the originality verification process. The Hamming distance is calculated by comparing the feature set that needs to be registered with the feature set that has been registered in the blockchain platform 200 one by one to determine whether the originality verification is successful. This method can greatly reduce the computing pressure of the blockchain platform 200 and reduce the expenditure on gasoline fees.

[0077] It is understandable that the transmission of traffic data in the Internet environment is unsafe and there is a risk of traffic data being tampered with. Therefore, it is necessary to verify the legitimacy of traffic data, as detailed below:

[0078] The registration data packet also includes a timestamp and a rights public key. The registration service specifically includes:

[0079] 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 stores the feature set, the timestamp and the right public key as Value values ​​in a storage domain.

[0080] Specifically, after the originality verification is successful, the blockchain platform 200 can perform hash operations based on the feature set to generate a digital fingerprint, where the digital fingerprint is used as a unique identifier of the copyright and plays a role in rapid retrieval. In addition, due to the anti-collision characteristics of the hash, the ownership of the rights can be clearly identified.

[0081] Specifically, the blockchain platform 200 can also use the timestamp in the registration data packet as the application date of the copyright, and use the public key of the right as the identifier of the identity of the right holder. The public key of the right can be the public key address of the client 100 or the public key address of the right holder entered by the user.

[0082] Furthermore, the blockchain platform 200 can store the above data in the form of a HashMap in the storage domain of the smart contract, and can use the digital fingerprint as the Key value, and the feature set, timestamp and right public key as the Value value to facilitate quick search.

[0083] The above process is the copyright registration process. The digital fingerprint generated based on the feature set serves as the unique identifier of the copyright, which can play a role in rapid indexing and clarifying rights.

[0084] The client 100 is further used to send a change data packet to the blockchain platform 200; the change data packet is generated by the client 100; the change data packet includes the registration certificate and the first digital signature;

[0085] Specifically, after the blockchain platform 200 obtains the change data packet, it can obtain the registration certificate and the first digital signature, and then verify the legitimacy of the change data packet based on the registration certificate and the first digital signature.

[0086] The registration certificate is used to record information related to the changed business, and the first digital signature can be obtained after the copyright owner signs the registration certificate using a private key.

[0087] The blockchain platform 200 is further used to perform signature verification on the change data packet; when the verification of the change data packet is successful, execute the change business related to the registration certificate; when the verification of the change data packet fails, reject the change data packet;

[0088] Specifically, after the blockchain platform 200 obtains the change data packet, it can read the registration certificate and the first digital signature contained in the change data packet, and can perform signature verification on the registration certificate.

[0089] Specifically, the registration certificate may include a digital fingerprint of the copyright that needs to be changed. The blockchain platform 200 can obtain the corresponding public key of rights based on the digital fingerprint. The blockchain platform 200 will then use the public key of rights to decrypt the first digital signature and obtain data and compare it with the registration certificate. When the two match, the signature verification is successful.

[0090] Specifically, the registration certificate also includes a target public key, which is the public key address of the copyright assignee. After the signature verification is successful, the blockchain platform 200 can modify the rights address corresponding to the digital fingerprint to the target public key value.

[0091] The above process is the signature verification and business change process. By setting up signature verification, the authenticity of the business change can be guaranteed. Malicious nodes cannot pass the verification without obtaining the private key corresponding to the public key of the right, thus ensuring the security of the system.

[0092] It is understandable that due to the irreversibility of blockchain technology, and the fact that the registration certificate is generated unilaterally by the right holder, if the two parties are changing the copyright, the right holder may record the target public key incorrectly during the generation of the registration certificate, resulting in the assignee being unable to obtain the copyright.

[0093] Therefore, a method jointly confirmed by both parties can be designed to change the copyright, as detailed below:

[0094] The change data packet also includes a second digital signature, the registration certificate includes the target public key and the digital fingerprint, and the signature verification specifically includes:

[0095] The blockchain platform 200 performs verification according to the right public key, the registration certificate and the first digital signature;

[0096] The blockchain platform 200 performs verification according to the target public key, the registration certificate and the second digital signature;

[0097] When all verifications pass, the signature verification is confirmed to be successful.

[0098] The second digital signature may be obtained by the copyright assignee signing the registration certificate using the assignee's private key, where the assignee's private key and the target public key together form a public-private key pair.

[0099] Specifically, the blockchain platform 200 can obtain the corresponding public key based on the digital fingerprint. The blockchain platform 200 will then use the public key to decrypt the first digital signature and obtain data and compare it with the registration certificate. When the two match, the signature verification is successful.

[0100] Furthermore, the blockchain platform 200 can obtain the target public key based on the registration certificate. The blockchain platform 200 then uses the target public key to decrypt the second digital signature to obtain data and compare it with the registration certificate. When the two match, the signature verification is successful.

[0101] Furthermore, after both signature verifications are passed, the blockchain platform 200 can execute the change business associated with the registration certificate.

[0102] 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 must also be confirmed to ensure the accuracy of the transferee.

[0103] It is understandable that symmetric encryption involves the management of symmetric keys, especially the distribution of symmetric keys. It requires the two communicating parties to exchange a shared symmetric key through another secure channel before communicating, so that the ciphertext can be safely transmitted through an insecure channel. Once the symmetric key is stolen, the encryption made by it will immediately become invalid.

[0104] Therefore, a method for transmitting symmetric keys using asymmetric encryption in an Internet environment can be specifically designed, as shown below:

[0105] Change business, including:

[0106] The blockchain platform 200 retrieves the corresponding right public key according to the digital fingerprint; and replaces the value of the right public key with the value of the target public key.

[0107] In the above process, the blockchain platform 200 quickly locates the public key of the rights through the digital fingerprint in the registration certificate, thereby realizing the rapid change of the copyright right holder by the system.

[0108] The following is a specific description of the embodiments of the present application, taking the data interaction between the client 100 and the blockchain platform 200 as an example.

[0109] Please also see Figure 4 , Figure 4 This is a schematic diagram of a data interaction process scenario between a client 100 and a blockchain platform 200 provided in one embodiment of the present application.

[0110] S401. The client 100 generates a feature set according to the source code data;

[0112] S402. The client 100 sends a registration data packet to the blockchain platform 200;

[0113] Specifically, the blockchain platform 200 can obtain the registration data packet sent by the client 100. The registration data packet sent by the client 100 to the blockchain platform 200 mainly includes a feature set of source code data.

[0114] S403. The blockchain platform 200 performs originality verification and performs registration services;

[0115] Specifically, after the blockchain platform 200 obtains the feature set, it can verify the originality of the feature set.

[0116] Specifically, after the originality verification is successful, the blockchain platform 200 can register the feature set as 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 generates a block, the relevant transaction is published to the blockchain network 10 to achieve the purpose of announcement and non-tamperability.

[0117] S404. The blockchain platform 200 returns the digital fingerprint to the client 100;

[0118] Among them, the digital fingerprint is used as the unique identifier of the copyright, which plays a role in rapid retrieval. In addition, due to the anti-collision characteristics of the hash, the ownership of the rights can be clearly identified.

[0119] S405. The client 100 sends a change data packet to the blockchain platform 200;

[0120] Specifically, after the blockchain platform 200 obtains the change data packet, it can obtain the registration certificate and the first digital signature, and then verify the legitimacy of the change data packet based on the registration certificate and the first digital signature.

[0121] S406. The blockchain platform 200 performs signature verification and executes the change business.

[0122] Specifically, the registration certificate also includes a target public key, which is the public key address of the copyright assignee. After the signature verification is successful, the blockchain platform 200 can modify the rights address corresponding to the digital fingerprint to the target public key value.

[0123] The above process is the data interaction process between the client 100 and the blockchain platform 200.

[0124] In summary, an embodiment of the present application provides a blockchain-based code copyright registration system.

[0125] By storing the feature set used to determine originality in the blockchain, the storage pressure of the blockchain and the computing gas fee can be reduced. The data fingerprint of the feature set is obtained by calculation as a copyright identifier to facilitate the confirmation of rights. In addition, double signature verification is set up to ensure the accuracy of the change of rights and prevent irreparable losses caused by the irreversibility of the blockchain network 10.
