Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Before explaining the embodiments of the present invention in detail, some terms related to the embodiments of the present invention are explained.

The copyright verification means that: the verification operation of the copyright of some contents in the blockchain system, such as the verification of the copyright of the original contents, the verification of the modification of the copyright of the contents, and the like.

Block chains: the block chain technique is a low-level technique of bit currency, which is a decentralized distributed account book database. The blockchain itself is a series of data blocks (i.e., blocks) that are generated using a cryptographic algorithm, and each data block contains information that identifies the validity of multiple blockchain network transactions. Based on the above, the data on the block cannot be tampered to cheat, and the data on any block can be ensured to be transparent and transparent, so that the security of the data is ensured.

Block chains can be classified as public, private, or federation chains. The federation chain is between the public chain and the private chain, and several organizations cooperate to maintain a blockchain, the use of the blockchain must be managed with authority, and related information can be protected, such as a financial organization. To summarize, a blockchain is a distributed database system participated by nodes, or may also be referred to as a distributed public ledger based on P2P (peer-to-peer) network, and is characterized by being unalterable, and can also be understood as an ledger system.

Node of blockchain: the device participating in building the blockchain, for example, the computer devices of each content vendor participating in building the blockchain, may be a single computer device such as a single server of a certain content vendor, or may be a computer device cluster of a certain content vendor such as a server cluster. The nodes of the block chain can be an execution main body of copyright verification, and business such as transaction can be realized through interaction between the nodes. The node stores relevant block data, for example, the block data may include transaction records and the like.

A copyright verification method, a copyright verification apparatus, a computer device, and a storage medium according to embodiments of the present invention will be described below. The copyright verification device may be integrated in a node of the blockchain, and the node may be a single server or a server cluster.

Referring to fig. 1a, an embodiment of the present invention provides a contribution system based on a block chain, where the system may implement a content contribution service, a copyright verification service of the contribution content, and other services. The system may include a plurality of nodes 10, wherein the plurality of nodes are connected by a network.

Each node device 10 may be configured to verify copyright of posted content, issue an award, and the like, and may be used as an accounting node of a block chain, and is configured to store transaction information during a transaction process and update the transaction information at regular time, so that other nodes in an implementation environment may share the transaction information, and thus each node may provide a consistency certificate for the transaction information, and improve security of the transaction information.

In a content contribution scene, a node may acquire contribution content sent by a terminal, such as a mobile phone 11 or a computer 12, and perform feature extraction on the contribution content to obtain target feature information of the contribution content; performing feature query on block data of the node 10 (i.e., the first node) according to the target feature information, where the block data includes feature information of existing copyright attribution content; when the block data is not inquired that the feature information identical to the target feature information exists, broadcasting a copyright verification request of the contribution content to other nodes 10 (namely, second nodes) except the node 10 in the block chain; receiving a copyright verification result returned by the other node 10 based on the verification request; and performing copyright verification on the contribution content based on the copyright verification result returned by the other node 10.

In addition, when the copyright verification of the posted content passes, the present node 10 issues an award to the terminal, and when the copyright verification of the posted content fails, the present node 10 rejects the posted content.

The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.

The embodiments of the present invention will be described from the perspective of a copyright verification apparatus, which may be integrated in any node of a blockchain, where the node may be a single server or a server cluster.

The blockchain may be a federation chain (i.e., a federation blockchain), for example, a federation chain cooperatively maintained by several content vendors, the federation chain constructed by devices of multiple content vendors according to a convention. The nodes in the federation chain may be individual devices of a content vendor or a device cluster. The copyright verification device of the embodiment of the invention can be integrated at any node in a alliance chain. In an embodiment, the federation chain may also consist of a content monitoring portion or a third-party independent notary authority.

In the copyright verification method provided in the embodiment of the present invention, the method may be executed by a processor of a first node in a blockchain, such as a federation chain, where the first node may be any node in the blockchain; as shown in fig. 1b, the specific flow of the copyright verification method may be as follows:

101. and acquiring the contribution content to be verified.

The contribution content may be content that the user submits to a content vendor or a content service platform, and the content may be content generated by authoring of the user, that is, UGC.

The content type of the contribution content may be various, for example, the type of image, video (e.g., short video), article, and the like.

For example, a node in the blockchain may retrieve a contribution video to be verified.

The contribution content may be sent by a user terminal or other nodes, for example, in a contribution scenario, the terminal may send the contribution content to a node of the blockchain, where the contribution content is the contribution content to be verified, and at this time, the contribution content to be verified sent by the terminal may be acquired.

102. And performing feature extraction on the contribution content to obtain target feature information of the contribution content.

The target characteristic information is characteristic information of the contribution content and is used for uniquely representing the contribution content.

The feature extraction mode of the contribution content may be various, for example, a deep learning network may be adopted to perform feature extraction on the contribution content; specifically, feature extraction may be performed on the contribution content by using a convolution layer in the deep learning network model to obtain convolution feature information, which is target feature information.

For another example, a message digest algorithm may be used to perform a digest calculation on the posted content, so as to obtain the feature information of the posted content.

Specifically, the step of "performing feature extraction on the posted content to obtain target feature information of the posted content" may include:

performing abstract calculation on the contribution content to obtain a hash value of the contribution content, such as a hash value with a fixed length;

and constructing target characteristic information of the contribution content based on the hash value.

For example, in an embodiment, the hash value may be directly used as the target feature information of the contribution content, for example, a fixed-length hash value of the contribution short video may be used as the feature information of the contribution short video.

The message digest algorithm may be selected according to actual requirements, and may be, for example, a digest algorithm such as SHA-512, MD5, SHA-1, SHA-256, or the like.

For example, SHA-512 may be used to perform digest calculation on the contribution content to obtain a HASH value with a length of 512 bits, and the HASH value with a length of 512 bits is used as the feature information of the contribution content.

103. And when the block data of the first node does not have the characteristic information which is the same as the target characteristic information, broadcasting a copyright verification request of the contribution content to a second node in the block chain, wherein the second node is a node except the first node in the block chain, and the block data comprises the characteristic information of the existing copyright attribution content.

The block data in the block chain, such as the block data in the alliance chain, may be metadata in the block chain, such as the alliance chain, and record the characteristic information of the existing copyright attribution content and the copyright attribution information of the existing copyright attribution content; for example, the tile data may include feature information of the short video, copyright attribution information of the short video, and the like.

For example, in an embodiment, the chunk data may include a plurality of transaction records, each transaction record may include two fields (the field length may be set according to actual requirements, such as a 512-bit field), each of which is a feature information field storing feature information of the content (for example, a hash value with a length of 512 bits) for characterizing a unique content, such as a short video; and the other is a copyright ownership information field for characterizing copyright ownership of the content such as short video. Each transaction record represents a piece of content, such as short video copyright information.

The existing copyright attribution content is content which already possesses copyright attribution, UGC content which can be posted for other users, content which is authored by a content manufacturer, and the like. The copyright ownership information may include information about a user, a manufacturer, and the like to which the content copyright belongs.

In one embodiment, whether the same characteristic information exists in the block data can be determined in a query mode; for example, feature query may be performed on the block data of the first node according to the target feature information, and when feature information that is the same as the target feature information exists in the block data of the first node, it is determined that feature information that is the same as the target feature information does not exist in the block data of the first node. On the contrary, when queried, it is determined that the same feature information as the target feature information exists.

For example, feature queries may be performed in the block data with the target feature information as a query object, so as to query whether feature information identical to the target feature information exists in the block data, thereby implementing copyright checking on the posted content.

The copyright verification request may be a transaction request initiated by a node in the blockchain, and the copyright verification request may carry feature information of the contribution content (e.g., a hash value of the contribution content) and copyright attribution information (e.g., identity information of the contributor, identity information of a content vendor, etc.).

The copyright verification request may be used to instruct the second node to perform copyright verification on the posted content, for example, instruct the second node to query whether the block data includes feature information that is the same as the feature information of the posted content, if so, return a copyright verification result that the copyright verification fails, and if not, return a copyright verification result that the copyright verification passes.

In an embodiment, the second node participating in the copyright verification may be selected from the blockchain according to actual requirements, and may be a previous node in a consensus mechanism participating in the copyright verification.

Referring to fig. 1c, in the embodiment of the present invention, after obtaining the feature information of the contribution content, it may be queried whether the same feature information exists in the tile data, so as to implement copyright check on the contribution content, and when the same feature information is not queried, it is preliminarily described that the contribution content may not have copyright ownership, may be original content, and further copyright storage operation is required.

Wherein, the copyright storage operation is as follows: broadcasting a copyright verification request of the contribution content to a second node in the block chain, and performing copyright verification on the contribution content based on a copyright verification result returned by the second node; and when the copyright verification is passed, the copyright storage is successful, otherwise, the copyright storage fails.

104. And receiving a copyright verification result returned by the second node based on the copyright verification request.

And the copyright verification result returned by the second node comprises that the copyright verification is passed or the copyright verification is not passed.

After receiving the broadcasted copyright verification request, the second node in the block chain can analyze target feature information of the posted content in the copyright verification request, then inquire whether feature information identical to the feature information of the posted content exists in the block data, if so, return a copyright verification result that the copyright verification fails, and if not, return the copyright verification result that the copyright verification passes.

105. And performing copyright verification on the contribution content based on the copyright verification result returned by the second node.

For example, in an embodiment, when all returned copyright verification results are verified, it is determined that the copyright of the posted content is verified, otherwise, the copyright of the posted content is not verified.

For example, in an embodiment, in order to improve the success rate of the copyright verification, the number of second nodes that pass the verification may be counted as the returned copyright verification result, and the verification is performed based on the number of second nodes. Specifically, the step "performing copyright verification on the posted content based on the copyright verification result returned by the second node device" may include:

counting the number of the second nodes passing the verification as the returned copyright verification result;

and performing copyright verification on the contribution content according to the second node number.

In an embodiment, after the first node receives the copyright verification result returned by the second node, the first node may count the number of second nodes whose copyright verification result is "verified". For example, assuming that a first node broadcasts a copyright verification request to 100 second nodes in a blockchain, each of the 100 second nodes may perform copyright verification according to the copyright verification request and return a copyright verification result to the first node (the result includes "verification passed" or "verification failed"); suppose that 80 second nodes return the copyright verification result as 'verification pass'. The first node may count the number of second nodes whose copyright verification result is "verified", which is 80 at this time.

For example, in an embodiment, when the number of the second nodes is greater than the preset number, it is determined that the copyright verification of the posted content passes, and when the number of the second nodes is not greater than the preset number, it is determined that the copyright verification of the posted content fails. The preset number may be set according to actual requirements, for example, the preset number may be set based on the total number of nodes in the block chain.

For another example, in one embodiment, a ratio of the number of second nodes that pass verification may be calculated, and verification may be based on the ratio. Specifically, the step "performing copyright verification on the contribution content according to the second node number" may include:

calculating the quantity proportion of the second node quantity to the total quantity of the second nodes in the block chain;

when the quantity ratio is larger than a preset threshold value, determining that the copyright of the contribution content passes verification;

and when the quantity proportion is not larger than the preset threshold value, determining that the copyright verification of the contribution content is failed.

The preset threshold may be set according to actual requirements, for example, 80%, 90%, and so on. For example, when the verification result is that the number of the second nodes passing the verification exceeds 80%, the copyright of the contribution content is determined to pass, and at this time, the copyright storage is successful; if not, determining that the copyright of the contribution content is not passed, and at this time, the copyright storage fails.

In the embodiment of the invention, when the copyright of the current contribution content such as the short video passes the verification, the contribution can be accepted and contribution rewards are issued to the contributors.

In an embodiment, when the copyright verification of the posted content passes, the feature information and the copyright attribution information of the posted content are synchronized to the block data of all nodes of the block chain, so as to ensure the synchronization of the data and improve the efficiency, the accuracy and the reliability of the future copyright verification.

In one embodiment, when it is found that the block data has the same feature information as the target feature information, it is determined that the copyright verification of the posted content is not passed.

Referring to fig. 1c, in the embodiment of the present invention, after obtaining the feature information of the contribution content, it may be configured to query whether the same feature information exists in the tile data, to implement a copyright check on the contribution content, and when the same feature information is queried, it is described that the contribution content has copyright ownership, and the contribution content may be a non-original work or there are situations of one contribution and multiple contributions, and at this time, it is determined that the copyright check on the contribution content passes, and the contribution is rejected.

According to the above description, referring to fig. 1c, taking the contribution content as the short video and the block chain as the alliance chain constructed by the short video manufacturers, by adopting the method of the embodiment of the present invention, when the node corresponding to the short video manufacturer receives the contribution of the short video user, first, the feature information of the short video is calculated, then the block data of the alliance chain is queried, if the same feature information can be queried, it is indicated that the short video has copyright attribution, is a non-original work or has multiple contributions for one contribution, and at this time, the contribution is rejected. If the characteristic information is not inquired, the copyright is proved to be original works, then copyright storage operation is carried out, namely, the node initiates trading broadcast, and after the number of the nodes confirmed by trading exceeds 80%, the copyright is regarded as successful, at the moment, the contribution is accepted, and contribution reward is issued to the contributor.

On the basis, in order to avoid tampering copyright data by content manufacturers and improve the reliability of copyright verification, the embodiment of the invention can also verify copyright modification based on a consensus mechanism of the block chain. Specifically, the method in the embodiment of the present invention further includes:

receiving a copyright modification request of target content, wherein the copyright modification request carries target copyright attribution information to which the target content needs to be modified;

broadcasting a copyright modification verification request of the target content to a second node in the block chain according to the copyright modification request;

The target content is content requiring copyright ownership information modification, such as a short video requiring copyright ownership information modification.

For example, when the content manufacturer needs to modify the copyright ownership information of a certain content, the content manufacturer's device may send a copyright modification request to the node of the blockchain, where the copyright modification request may carry the copyright ownership information that needs to be modified from the content.

In one implementation, after receiving the copyright modification request, the node of the blockchain may trigger copyright modification verification according to the request, that is, broadcast a copyright modification verification request to other nodes in the blockchain, where the request may carry the feature information of the content and the copyright attribution information that needs to be modified.

After receiving the copyright modification verification request, the other nodes can perform copyright verification, specifically, can query block data according to the characteristic information of the content to obtain copyright attribution information corresponding to the characteristic information; and then, comparing the inquired copyright attribution information with the copyright attribution information needing to be modified, if the inquired copyright attribution information is not consistent with the copyright attribution information needing to be modified, returning a verification result that the copyright modification verification fails to pass to the request initiating node, and if the inquired copyright attribution information is consistent with the copyright attribution information needing to be modified, returning a verification result that the copyright modification verification passes to the request initiating node.

The request initiating node, after receiving the copyright modification verification result returned by other nodes,

and determining whether the copyright modification verification passes based on the returned verification result, if so, modifying the copyright attribution information of the target content according to the target copyright attribution information, and if not, rejecting the modification. In addition, under the condition that the copyright modification verification is passed, the modified copyright attribution information of the target content needs to be synchronized with other block data in the block chain.

Specifically, the manner of determining whether the current modification verification passes based on the returned verification result may refer to the manner of the copyright verification, for example, count the number of second nodes that the copyright modification verification result passes, and determine whether the copyright modification verification of the content passes according to the number of second nodes.

For example, when a certain short video manufacturer needs to tamper the copyright ownership of a certain short video as itself, by using the method provided by the embodiment of the present invention, the tampering can be found through the consensus mechanism of the block chain, and the tampering is rejected at the same time.

As can be seen from the above, in the embodiment of the present invention, the contribution content to be verified is obtained through the first node in the block chain; performing feature extraction on the contribution content to obtain target feature information of the contribution content; performing characteristic query on block data of the first node according to the target characteristic information, wherein the block data comprises the characteristic information of the existing copyright attribution content; when the block data of the first node does not have the feature information which is the same as the target feature information, broadcasting a copyright verification request of the contribution content to a second node in the block chain, wherein the second node is a node except the first node in the block chain, and the block data comprises the feature information of the existing copyright attribution content; receiving a copyright verification result returned by the second node based on the copyright verification request; and performing copyright verification on the contribution content based on the copyright verification result returned by the second node. According to the scheme, decentralized copyright verification can be realized based on the block chain, the problems of one draft, multiple submissions, carrying of the submissions and the like can be effectively avoided, and the problem of copyright data tampering can be avoided, so that the accuracy and the credibility of the copyright verification and the safety of the copyright data can be improved.

Based on the above description of the embodiments, the following will describe the copyright verification method according to the embodiments of the present invention in detail by taking the copyright verification device integrated in the node in the federation chain and the content as a short video as an example:

firstly, building a federation chain:

first, a federation chain needs to be constructed, where nodes in the federation chain correspond to short video vendors, for example, the nodes in the federation chain can be implemented by a server or a server cluster of short video vendors. Each short video manufacturer operates through its own node when performing short video copyright check and copyright storage. Each node corresponds to block data, the block data comprises a transaction record, the transaction record comprises two fields with the length of 512 bits, one field is a characteristic information field, and the characteristic information of the short video is stored and used for representing only one short video; the other is a copyright attribution information field which stores the copyright attribution information of the short video and is used for representing the copyright attribution of the short video; wherein each transaction record represents a piece of short video copyright information.

Referring to fig. 2a, a federation chain constructed by each short video vendor, the nodes in the federation chain corresponding to the short video vendors, may be implemented by a server of the short video vendor. For example, each node in the federation chain corresponds to a short video vendor 1, 2, 3, 4, 5, respectively.

Secondly, after the alliance chain is constructed, the alliance chain can be adopted for copyright verification:

as shown in fig. 2b, a copyright verification method is provided, which specifically comprises the following steps:

201. and the contributor terminal sends the contribution short video to a first node corresponding to a short video manufacturer in the alliance chain.

The first node is a node corresponding to a short video vendor currently submitted by the contributor in the alliance chain.

For example, referring to fig. 2a, when a contributor contributes a short video to a short video vendor 5 platform, the contributor may send the contributor short video to a alliance-link node corresponding to the short video vendor 5 through a terminal.

202. And the first node performs characteristic calculation on the contribution short video to obtain target characteristic information of the contribution short video.

For example, the summary calculation may be performed on the posted short video file data, and the summary algorithm selects SHA-512 to obtain a HASH value with a length of 512 bits, which is the feature information of the short video.

203. And the first node performs characteristic query on the block data according to the target characteristic information.

For example, the second node may inquire in the tile data whether there is the same feature information as the target feature information.

204. And when the characteristic information which is the same as the target characteristic information is not inquired, the first node broadcasts a copyright verification request carrying the target characteristic information to a second node in the alliance chain.

And the second node is any node except the first node in the alliance chain. For example, nodes in the alliance chain except the node corresponding to the short video vendor 5, such as nodes corresponding to short videos 1, 2, 3, 4, etc.

For example, referring to fig. 2b, after calculating the HASH value of the posted short video, it may be queried in the tile data whether to have the same HASH value; if not, if the records with the same HASH value are not inquired, the record is considered as original works, and at the moment, copyright storage certificate is launched. The copyright storage process refers to step 204-207.

For example, the first node corresponding to the short video manufacturer 5 initiates a transaction broadcast in the alliance chain, the HASH value of the posted short video is filled in the characteristic information field of the transaction request, and the identity information of the copyright attribution information field, such as the manufacturer name, is filled in the copyright attribution information field. Based on the consensus mechanism, other nodes in the alliance chain can perform broadcast transaction confirmation, and determine whether the certificate is stored or not based on the number of the confirmed nodes of the transaction to be broadcast, for example, after the number of the confirmed nodes of the transaction to be broadcast exceeds 80%, the certificate can be considered to be stored or not, otherwise, the certificate is not stored.

205. And the first node receives a copyright verification result returned by the second node based on the copyright verification request.

After receiving the copyright verification request broadcast by the first node, the second node in the alliance chain can query the corresponding block data according to the request, determine whether the same characteristic information of the posted short video exists in the block data, if so, return the copyright verification result which fails the copyright verification to the first node, and if not, return the copyright verification result which passes the copyright verification to the first node.

206. And the first node counts the returned copyright verification result as the number of the second nodes passing the verification.

207. And the first node determines whether the copyright verification of the contribution short video passes according to the number of the second nodes.

For example, the number ratio of the second node number to the total number of the second nodes in the block chain is calculated; when the number proportion is larger than the preset proportion, determining that the copyright of the contribution short video passes verification; otherwise, the copyright verification of the contribution short video is determined not to be passed.

And when the copyright verification is not passed, the copyright storage is failed or not completed.

208. When the characteristic information identical to the target characteristic information is inquired, the first node determines that the copyright verification of the contribution short video is not passed.

For example, referring to fig. 2b, after the HASH value is calculated, through its own node, a federation link block transaction information query is performed, and if a record with the same HASH value is queried, it indicates that the short video already has copyright ownership, and the user contribution is a non-original work or one-contribution multiple-contribution, at which time the contribution system rejects the contribution request.

Or when the certificate storage is not completed, determining that the copyright verification is not passed, and rejecting the contribution request by the contribution system at the moment.

Referring to fig. 2b, after the copyright verification of the contribution short video passes and the confirmation is confirmed to be completed, the contribution system accepts the contribution and issues a contribution award to the contributor.

By adopting the copyright verification method provided by the embodiment of the invention, the weak centralization and the non-tamper property of the alliance chain can be utilized, the short video characteristic information is recorded by establishing the alliance chain of the certification authority and is accessed into the UGC short video contribution system, so that the phenomena of one contribution and multiple contribution and carrying contribution are reduced, and the probability of copyright dispute is reduced.

For example, referring to fig. 2c, five short video vendors "short video vendor 1", "short video vendor 2", "short video vendor 3", "short video vendor 4", "short video vendor 5" are accessed in the alliance chain.

Normal contribution scenario:

a. contributor a takes a short video VidA and contributes to short video vendor platform 3.

b. And after receiving the contribution, the short video manufacturer platform 3 performs copyright check in a alliance chain.

c. And (5) after the union link copyright check is passed, initiating union link copyright storage certificate.

d. The alliance chain copyright storage certificate passes, and the short video manufacturer platform 3 accepts the contribution.

e. Contributor a receives the contribution award issued by short video vendor platform 3.

Carrying a contribution scene:

a. contributor B downloads a short video VidB from short video vendor platform 4 and then contributes to short video vendor platform 1.

b. And after receiving the contribution, the short video manufacturer platform 1 performs copyright check in a alliance chain.

c. The alliance chain copyright check fails and the short video vendor platform 1 rejects the contribution.

A draft-multiple-projection scenario:

a. the short video vendor platform 4 takes a short video VidC and then submits a short video to both the short video vendor platform "short video vendor platform 3 and short video vendor platform 4.

b. And after receiving the contribution, the short video manufacturer platform 3 and the short video manufacturer platform 4 respectively perform copyright check in the alliance chain.

c. The federation chain copyright checks of the two pass, and then the two initiate the federation chain copyright storage.

d. The copyright of the short video manufacturer platform 4 is stored earlier than that of the short video manufacturer platform 3, so that the copyright of the short video manufacturer platform 4 passes and the copyright of the short video manufacturer platform 3 fails.

e. The short video vendor platform 4 accepts the contribution and the short video vendor platform 3 rejects the contribution.

f. Contributor C receives a contribution award from short video vendor platform 4.

Vendor proprietary tampering scenario

a. The short video manufacturer 2 privately tampers with copyright ownership of the short video VidD as itself and synchronizes data to the alliance chain.

b. The consensus mechanism of the alliance chain discovers the tampering and rejects the tampering.

As can be seen from the above, the embodiment of the present invention provides a UGC short video contribution system with weak centralized copyright authentication, which can effectively avoid the problem of one contribution and multiple contribution transportation, and improve the reliability of short video contribution, thereby reducing the cost expenditure of invalid contribution, and also reducing the probability of copyright disputes, and meanwhile, due to the improvement of the reliability of contribution, the contribution auditing and contribution reward issuing can be automatically performed, thereby optimizing the contribution experience and reducing the labor expenditure.
