terminal devices

10a, 10b, and a hosting server 10 c. An intelligent contract can be deployed in the block chain node, the data volume (namely digital assets) corresponding to the copyright works is distributed based on the distribution proportion in the intelligent contract, the distribution data volume corresponding to each distribution object can be obtained, and the distribution data volume is transferred to the account corresponding to each distribution object; the blockchain node can submit the data distribution result to a shared account book (or called a distributed account book, a shared account book, etc.); the intelligent contract is provided with distribution time and distribution proportion corresponding to distribution objects. The terminal device 10a and the terminal device 10B refer to terminal devices corresponding to allocation objects (for example, the terminal device 10a is a terminal device corresponding to the allocation object a, and the terminal device 10B is a terminal device corresponding to the allocation object B), when the allocation object a disagrees with the allocation data amount transferred by the block link point, the terminal device 10a corresponding to the allocation object a may send an allocation verification request to the block link network, and the block link point may recalculate the allocation data amount corresponding to the allocation object a according to the allocation verification request, and return the calculated result to the terminal device 10a, and may submit the recalculated result to the shared account book. The hosting server 10c is configured to store a data amount corresponding to the copyrighted work, connect to a blockchain network, and provide a hosting account interface for the blockchain link point, so that the intelligent contract in the blockchain node obtains the data amount from the hosting account of the hosting server 10c based on the hosting account interface.

The

terminal devices

10a and 10b may each include a mobile phone, a tablet computer, a notebook computer, a palm computer, a Mobile Internet Device (MID), a wearable device (e.g., a smart watch, a smart band, etc.), and the like.

Please refer to fig. 2, which is a schematic diagram of a data distribution scenario provided in the embodiment of the present application. The copyright revenue refers to all revenue (including fund, flow, virtual assets and the like) obtained by the copyright works, and the copyright revenue liquidation refers to dividing the revenue obtained by the copyright works according to a distribution proportion and transferring the divided revenue to accounts of copyright distribution objects respectively. Taking a film copyright profit clearing scene as an example, the data distribution scheme provided by the present application is specifically described, the copyright profit at this time refers to a general ticket house of the film, and the copyright distribution object corresponding to the film may include: the distribution method includes distributing objects 1 (such as a distributor), distributing objects 2 (such as a cinema), distributing objects 3 (such as a distributor) and the like, and a distribution agreement can be signed through negotiation among the copyright distributing objects, the distribution agreement can include information such as distribution proportion corresponding to each copyright distributing object and distribution time of copyright revenue, for example, the distribution proportion corresponding to the distributing object 1 is 38%, the distribution proportion corresponding to the distributing object 2 is 50%, the distribution proportion corresponding to the distributing object 3 is 7%, and the like, the distribution time can be distributed once every 10 days, namely, 10 days is a distribution time period, and when the copyright revenue is distributed once in the number 1 month, the next revenue distribution time is the number 1 month, 11. After each copyright allocation object signs an allocation protocol, the allocation protocol can be submitted to the blockchain network and be packed into blocks by the blockchain nodes for uplink. In the block chain, an intelligent contract may be deployed, in which the distribution time of the copyright revenue and the distribution ratio corresponding to each copyright allocation object may be set, and the distribution time and the distribution ratio set in the intelligent contract are determined according to the distribution protocol. As shown in fig. 2, the node 20a is a blockchain node in a blockchain network, and the node 20a may perform an intelligent contract to distribute copyright revenue. When the allocation time is not reached, the revenue of the movie may be temporarily stored in an escrow account, where the escrow account may refer to an account opened at a bank and managed by the escrow server 10c, when the revenue of the movie is transferred into the escrow account, the digital assets in the escrow account may change, and the escrow server 10c may record the revenue value of each transfer, and the transfer time point, for example, the status record table 20b of the escrow account includes: the escrow account transfers to a profit value of 1 at time point 1, a revenue value of 2 at time point 2, a profit value of 3 at time point 3, a profit value of 4 at time point 4, etc.

The node 20a may obtain the system time information in real time, and when the system time information meets the allocation time node, that is, the allocation time of the copyright revenue is reached, the node 20a may call a managed account interface in the intelligent contract, and obtain all revenue in the allocation time period to which the system time information belongs from the managed account, where if the allocation time period is 10 days and the current system time information is No. 10/1 in 2019, the allocation time period to which the current system time information belongs is 2019/21 in 2019 (that is, the last allocation time node) -2019/10/1 in 2019 (the current allocation time node). Summarizing income values of transfer time points in the hosting account, which belong to the distribution time period of the system time information, to obtain total income in the distribution time period of the system time information, if it is detected from the state record table 20b that the transfer time points corresponding to the income values 1 to 4 all belong to the distribution time period, accumulating the income values 1, 2, 3 and 4 to obtain the total income value in the distribution time period of the system time information, distributing the counted total income value according to the distribution example information 20c in the intelligent contract to obtain the distribution income value corresponding to each copyright distribution object, and transferring assets corresponding to the distribution income values from the hosting account to the accounts of the distribution objects. For example, if the total profit value in the distribution time period to which the system time information belongs is 100 yuan, it may be determined according to the distribution proportion information 20c that the distribution profit value corresponding to the distribution object 1 is 38 yuan, the distribution profit value corresponding to the distribution object 2 is 50 yuan, and the distribution profit value corresponding to the distribution object 3 is 7 yuan; furthermore, 38 yuan may be transferred from the managed account to the account 1 corresponding to the allocation object 1, 50 yuan may be transferred to the account 2 corresponding to the allocation object 2, and 7 yuan may be transferred to the account 3 corresponding to the allocation object 3.

Fig. 3 is a schematic flow chart of a data distribution method based on an intelligent contract according to an embodiment of the present application. As shown in fig. 3, the method may include:

step S101, acquiring a data volume to be transferred associated with a target work, and adding the data volume to be transferred to a managed account; the hosting account is used for storing all data volumes to be transferred aiming at the target work;

specifically, after receiving transaction data for a target work submitted by a client, a blockchain node may process the transaction data, obtain a transfer data volume associated with the target work according to a transaction data processing result, and add the data volume to be transferred to a hosting account, where the hosting account may be used to store all data volumes to be transferred of the target work, the hosting account may be a hosting account of a bank, the data volume to be transferred may be obtained from the hosting account through a hosting account interface in an intelligent contract of a blockchain, and the data volume to be transferred may include digital assets, virtual assets, and the like, which is not specifically limited herein. Optionally, the escrow account may also be an on-chain virtual coin account, and the escrow account at this time may store a virtual coin with the value equal to the data to be transferred corresponding to the target work.

The target works can be multimedia copyright data, such as movie and television works, audio works, pictorial works and the like. Taking the target work as a movie, when the movie is shown in each large cinema, the user can purchase movie tickets at the cinema or ticket purchasing platform to go to the cinema to watch the movie; when a user purchases a movie ticket on the ticket purchasing platform, a client corresponding to the ticket purchasing platform may upload transaction data to the blockchain network, where the transaction data may be used to instruct the blockchain network to deduct an amount corresponding to a movie fare from an account of the user, and transfer the amount to an account specified by the ticket purchasing platform (e.g., a escrow account corresponding to the movie). After the transaction data is successfully processed, the block link points can add the amount corresponding to the movie fare to the escrow account. For example, the movie fare is 50 yuan, and the transaction data uploaded to the blockchain network by the client corresponding to the ticket buying platform may include: the account information of the user, the account information designated by the ticket buying platform, the purchased movie tickets and the transaction contents are transferred from the account of the user to the account designated by the ticket buying platform, and after the blockchain network receives the transaction data, the validity of the transaction data can be verified, for example, whether a submitter of the transaction data is a client corresponding to the ticket buying platform or not is detected, whether the balance in the account of the user is enough to complete the transaction or not is detected. When the transaction data is valid data, the block chain network can successfully complete the transaction, and the movie fare in the transaction data is the data volume to be transferred corresponding to the movie and can be stored in the escrow account corresponding to the movie; when the transaction data is invalid data, the transaction cannot be successfully completed, that is, in the transaction, the block link point cannot acquire the data volume to be transferred. It should be appreciated that the amount of movie tickets paid for each user to purchase the movie tickets may be added as a transfer-with-data amount to the corresponding escrow account for the movie.

Step S102, when the system time information is detected to meet the distribution time node in the intelligent contract, acquiring the total amount of data to be transferred in the distribution time period to which the system time information belongs from the escrow account;

specifically, before the block chain node performs step S102, it may acquire copyright allocation data associated with the target work, generate an allocation block according to the copyright allocation data, and add the allocation block to the allocation block chain, where the copyright allocation data includes an allocation protocol between copyright allocation objects associated with the target work, and set an allocation time period and an allocation ratio corresponding to the copyright allocation objects in the intelligent contract according to the allocation protocol stored in the allocation block chain. The distribution block chain is used for recording distribution data corresponding to all works respectively.

It should be understood that the copyright allocation object corresponding to the target work may be agreed upon and agreed upon to have a uniform opinion, and then a distribution agreement may be made, which may include: copyright information, copyright distribution object information, distribution proportion and distribution time and other information corresponding to the copyright distribution object respectively; after the copyright allocation object signs an allocation protocol, a requester (which may be a client corresponding to the copyright allocation object or a client corresponding to a work copyright holder) may create a key pair by using an asymmetric encryption algorithm; asymmetric encryption algorithms herein may include, but are not limited to: the Elgamal algorithm (an asymmetric encryption algorithm), the Rabin algorithm (an asymmetric encryption algorithm), the Diffie-Hellman algorithm (an asymmetric encryption algorithm), the ECC algorithm (elliptic curve encryption algorithm). The key pair may include a public key and a private key, and the private key is used for the requesting party to digitally sign the data uploaded to the blockchain network. After creating the key pair, the requestor may upload the public key of the key pair to the blockchain network, while the private key is kept by the requestor. It should be noted that the public keys in the blockchain network are unique, and one public key corresponds to one requester.

After the public key is uploaded to the blockchain network by the requester, the requester is indicated to finish identity registration in the blockchain network, and the requester has the qualification of data submission and information viewing in the blockchain network at the moment. Therefore, the requester can upload the distribution protocol as copyright distribution data of the target work to the blockchain network. After receiving the copyright allocation data uploaded by the requester, the block chain node can check and sign the copyright allocation data according to a public key corresponding to the requester, package the copyright allocation data passing the check and sign into an allocation block, verify the allocation block according to a consensus mechanism, and add the allocation block passing the verification into an allocation block chain.

The process of checking the copyright distribution data by the block link points specifically comprises the following steps: the block chain node can decrypt the digital signature carried by the copyright allocation data according to the public key corresponding to the requester to obtain first abstract information corresponding to the digital signature, and further perform hash operation on the received copyright allocation data according to a hash algorithm to generate second abstract information corresponding to the received copyright allocation data, if the first abstract information is detected to be the same as the second abstract information, the copyright allocation data passes verification, the uplink request is determined to be legal, the allocation block can be generated according to the copyright allocation data, and the agreed allocation block is added to the allocation block chain. If the digital signature carried in the copyright allocation data received by the block chain node is not the digital signature of the requester, that is, the digital signature in the copyright allocation data is generated by using a false private key, the block chain node directly displays that the decryption fails when decrypting by using a real public key. The first summary information is summary information of copyright allocation data obtained by a requester through Hash operation calculation, the second summary information is summary information of copyright allocation data actually received through block link points through Hash operation calculation, and Hash algorithms used by the requester and the block link nodes are the same. The hash algorithm can compress data or message into summary, not only can fix the format of data, but also can make the data smaller, and the hash algorithm can include but is not limited to SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512. Taking the SHA-256 algorithm as an example, the SHA-256 algorithm can generate a 256-bit hash value for any size of data, and can generate different hash values for different data.

The process of identifying the distribution block by the block link point specifically comprises the following steps: the block link node may broadcast the generated allocation block in the block chain network, that is, the allocation block is sent to the other nodes in the block chain network in a point-to-point transmission manner, after the other nodes verify the allocation block, the verification result may be broadcast in the block chain network, when a node exceeding a number threshold (the number threshold is associated with a common identification mechanism, and different common identification mechanisms may correspond to different number thresholds, such as 51%) in the block chain network passes through the allocation block, it indicates that the allocation block passes the common identification, and may add the allocation block to the allocation block chain for formal uplink. Wherein, the consensus algorithm includes but is not limited to: proof of Work (PoW), Proof of rights (PoS), Proof of Work and Proof of rights (PoW + PoS), Proof of equity authorization (Delegated Proof of stamp, DPoS), Practical bypath Fault-tolerant algorithm (PBFT), and Rayleigh Consensus Protocol (RCP).

The block chain node may set the allocation time period and the allocation proportion corresponding to the rights allocation object in the intelligent contract according to the allocation protocol stored in the allocation block chain. The intelligent contract refers to a computer program code written by a developer by using an intelligent contract high-level language, the intelligent contract written by the high-level language can be compiled into byte codes in an Ethernet workshop virtual machine of the block chain nodes through a compiler, and the Ethernet workshop virtual machine can be used for interpreting and executing the byte codes in the intelligent contract. The intelligent contract high-level languages include, but are not limited to, identity (an intelligent contract programming language), Serpent (an intelligent contract programming language), and LLL (an intelligent contract programming language), for example, a developer may write an intelligent contract using identity, and use a compiler to compile the intelligent contract written by identity into an ethernet virtual machine byte code, and then submit the compiled ethernet virtual machine byte code to a blockchain network along with transaction data and uplink the ethernet virtual machine byte code. A plurality of contract methods such as a method of setting distribution time, a method of setting distribution proportion, a method of setting distribution object, and the like may be included in the smart contract. The block chain node may obtain a public key corresponding to the rights allocation object in the allocation protocol (a client corresponding to the rights allocation object may create a key pair in advance and upload the public key in the key pair to the block chain network), and transmit the public key corresponding to the rights allocation object, the allocation time in the allocation protocol, and the allocation proportion corresponding to the rights allocation object as parameters into the intelligent contract, thereby completing the setting of the allocation time period and the allocation proportion in the intelligent contract.

After the allocation time period and the allocation proportion corresponding to the copyright allocation object are set in the intelligent contract, if the block link point detects that the system time information meets the allocation time node in the intelligent contract, the allocation time period corresponding to the system time information can be determined as a target allocation period, a hosting account interface in the intelligent contract is called, all data volumes to be transferred in the target allocation period are obtained from the hosting account and accumulated, and the total data volume to be transferred for the target work in the target allocation period is obtained. For example, if the distribution time period set in the intelligent contract is one month, 8:00 am # 1 of each month is a distribution time node, and when the system time information is 8:00 am # 1 of 10 months in 2019, the system time information satisfies the distribution time node in the intelligent contract, and the target distribution time period corresponding to the system time information is: the block link points can call a hosting account interface in an intelligent contract from 2019, 9/month, 1/day 8:00 to 2019, 10/month, 1/day 8:00, the data volume to be transferred within the time range from 2019, 9/month, 1/day 8:00 to 2019, 10/month, 1/day 8:00 is obtained from the hosting account, all the data volume to be transferred within the target distribution time period are accumulated, and the total data volume to be transferred for the target work within the target distribution time period can be obtained.

Step S103, acquiring a distribution proportion corresponding to the copyright distribution object from the intelligent contract, determining a distribution data amount corresponding to the copyright distribution object according to the distribution proportion and the total amount of the data to be transferred, and transferring the distribution data amount to a target account of the copyright distribution object.

Specifically, the block link point may obtain a distribution ratio corresponding to the rights distribution object from the intelligent contract, multiply the total amount of data to be transferred by the distribution ratio corresponding to the rights distribution object to obtain a distribution data amount corresponding to the rights distribution object, and transfer the distribution data amount to a target account of the rights distribution object through the intelligent contract, where the target account may be a client corresponding to the rights distribution object in the intelligent contract. For example, the copyright allocation object corresponding to the target work includes: allocation object 1, allocation object 2; the distribution ratio corresponding to the distribution object 1 is 40%, and the distribution ratio corresponding to the distribution object 2 is 60%; when the total amount of data to be transferred in the target allocation period is a, the allocation data amount corresponding to the allocation object 1 is: a × 40%, the allocation data amount corresponding to the allocation object 2 is: a × 60%, and then a × 40% of the data amount may be transferred from the managed account to the account of allocation object 1, and a × 60% of the data amount may be transferred from the managed account to the account of allocation object 2.

Fig. 4 is a schematic flow chart of another intelligent contract-based data distribution method according to an embodiment of the present application. As shown in fig. 4, the method may include:

step S201, acquiring a data volume to be transferred associated with a target work, and adding the data volume to be transferred to a managed account;

step S202, when detecting that the system time information meets the distribution time node in the intelligent contract, acquiring the total amount of data to be transferred in the distribution time period to which the system time information belongs from the escrow account;

step S203, acquiring a distribution proportion corresponding to the copyright distribution object from the intelligent contract, determining a distribution data amount corresponding to the copyright distribution object according to the distribution proportion and the total amount of the data to be transferred, and transferring the distribution data amount to a target account of the copyright distribution object;

the specific implementation process of steps S201 to S203 may refer to steps S101 to S103 in the embodiment corresponding to fig. 3, which is not described herein again.

Step S204, when receiving a distribution verification request aiming at the copyright distribution object sent by a request terminal, determining a target work related to the copyright distribution object according to the distribution verification request, and acquiring a distribution block related to the target work from a distribution block chain;

specifically, after the block link point transfers the allocation data volume to the account of the copyright allocation object according to the intelligent contract, if the copyright allocation object disagrees with the allocation data volume transferred by the block link point, if the amount of the allocation data volume is deemed to be inaccurate, the copyright allocation object may send an allocation verification request for the target work to the block link network through the request terminal. After the block link node receives the distribution verification request sent by the request terminal, the copyright distribution object and the related information (such as the name of the work, the author information of the work, and the like) of the target work can be determined according to the distribution verification request, the related information of the target work is used as a parameter, and the distribution block associated with the target work is obtained from the distribution block chain.

Step S205, generating a data verification result corresponding to the rights assignment object according to the assignment protocol included in the assignment block and the assignment data amount carried in the assignment query request, and sending the data verification result to the requesting terminal.

Specifically, the block link point may obtain a distribution protocol stored in the distribution block, read a distribution time period in the distribution protocol and a distribution proportion corresponding to the copyright distribution object, determine a total amount of data to be transferred in a target distribution period from the escrow account, re-determine a data amount corresponding to the copyright distribution object according to the distribution proportion and the total amount of data to be transferred in the distribution protocol, and call the re-calculated data amount as a data amount to be processed; if the amount of data to be processed is the same as the amount of distribution data actually received by the rights distribution object, determining the amount of distribution data actually received by the rights distribution object as a valid data state, that is, the amount of distribution data is not in error, and generating a data verification result corresponding to the rights distribution object according to the valid data state, for example, the data verification result in the valid data state may be: the distribution data volume is verified, and no error occurs; if the data volume to be processed is different from the distributed data volume actually received by the rights distribution object, determining the distributed data volume actually received by the rights distribution object as a data invalid state, that is, the distributed data volume is wrong, and generating a data verification result corresponding to the rights distribution object according to the data invalid state, for example, the data verification result in the data invalid state may be: the allocation data amount is erroneous. When the amount of distribution data corresponding to the rights distribution object is incorrect, the blockchain may re-transfer the data in the account of the rights distribution object, for example, by re-calculating, it is determined that 10 more bits are transferred in the account of the rights distribution object a, and 10 less bits are transferred in the account of the rights distribution object B, so that the blockchain link point may transfer 10 bits from the account of the rights distribution object a to the account of the rights distribution object B. In other words, since the data in the block chain has non-tamper-resistance, when the copyright allocation object has dispute about the allocation data amount, it can be verified whether there is a problem in the allocation data amount corresponding to the copyright allocation object according to the allocation protocol stored in the allocation block chain.

Please refer to fig. 5, which is a schematic diagram of a verification scenario for allocating data amount according to an embodiment of the present application. When the copyright allocation object disagrees with the allocation data volume transferred in the account, the request terminal can send an allocation verification request to the blockchain network so as to apply verification of the authenticity of the allocation data to the blockchain network. As shown in fig. 5, the requesting terminal 30a may send an allocation verification request to the tile link point 30b, where the allocation verification request may carry information such as a rights allocation object (e.g., object c) initiating the verification request, an allocation data amount (e.g., the allocation data amount is M) transferred to an account, and a target work (e.g., work b), that is, the allocation verification request is an allocation verification request initiated by the object c for the work bb. After receiving the allocation verification request sent by the request terminal 30a, the blockchain node 30b may determine the total amount of transfer data corresponding to the work b from the escrow account 30c, and a system to which the escrow account 30c belongs may record each data amount transferred to the escrow account 30c and transfer time information corresponding to each data amount, for example, the data amount 1 is transferred to the escrow account 30c at time point 1, the data amount 2 is transferred to the escrow account 30c at time point 2, and the like; according to the data recorded by the system to which the managed account 30c belongs, the total amount of the transfer data corresponding to the work b can be determined to be N.

The block chain node 30b may further obtain, from the distribution block chain 30d, a distribution protocol 30e associated with the work b, and may determine, from the distribution protocol 30e, that the distribution proportion corresponding to the object c is 35%, multiply the total amount of transfer data N by the distribution proportion 35%, obtain again the data amount corresponding to the object c as K, and at this time, refer to the data amount obtained by recalculation as the data amount to be processed. When the data volume K to be processed is the same as the allocated data volume M actually transferred to the object c, it may be determined that the allocated data volume M is valid data, and "the allocated data volume M is valid data" is returned to the request terminal 30a as a verification result; when the data amount K to be processed is different from the allocated data amount M actually transferred to the object c, it may be determined that the allocated data amount M is invalid data, and "the allocated data amount M is invalid data" is returned to the request terminal 30a as a verification result.
