Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

First embodiment

Fig. 1 is a flowchart of a method for processing media content based on a blockchain according to a first embodiment of the present application, which is applicable to processing media content. The method is particularly suitable for the processing condition of the media content created by the media creator when the media creator releases the original media content. The method may be performed by a media author. The media creator may refer to a media distributor distributing the media content originally created by the media distributor. Optionally, the device of the medium creator may be a blockchain network node (e.g., may be a normal blockchain node or may be a lightweight node), or may not be a blockchain network node, but may interact with the blockchain network through an interface provided by the blockchain network. The method can be performed by a blockchain-based media content processing apparatus provided in the seventh embodiment of the present application, which can be implemented in software and/or hardware and can be integrated into a media creator device. Referring to fig. 1, the method may specifically include:

s101, if the creation requirement of the media content exists, the media content is uploaded to a content library.

In the present application, the media content may be specific information delivered by the message dissemination tool, and for example, the media content may be news content, advertisement content, or image content. The content library may be a database storing media content that has been distributed. The solution of the embodiment of the present application is directed to publishing media content on a network platform, and for the network platform, each platform may have its own content library for storing the media content published on the network platform. Alternatively, the content library of repeatedly distributed media content (e.g., forwarded media content) may be stored only once.

Optionally, in this embodiment of the application, when the media creator wants to publish the original media content on a certain network platform, the original media content may be edited on an application client provided by the network platform, and then a sending button is clicked, at this time, the application client may respond to a sending instruction triggered by a user, and upload the media content edited by the user to a content library of a backend network platform thereof, so as to publish the media content edited by the user on the network platform, and at this time, all users of the network platform may view the media content through the application clients thereof.

Optionally, in this embodiment of the present application, the content library storing the media content may be a cloud storage system or a block chain storage system. The cloud storage System is a storage System built by adopting a cloud computing architecture or a point-to-point distributed File System (IPFS) technology, and has the advantage of low cost; the block chain storage system is constructed by adopting a block chain network technology, and has the advantages of higher safety and reliability. The selection can be carried out according to actual requirements.

Optionally, when the network platform selects a cloud storage system with a lower cost, in order to prevent media content stored in the content library from being tampered, the embodiment of the present application may be optimized in at least one of the following manners:

in the first mode, when the content library is a cloud storage system, the content library is set as a distributed main cloud storage system and a distributed backup cloud storage system, and correspondingly, when the media content is uploaded to the content library, the media content can be uploaded to the main cloud storage system and the backup cloud storage system. It should be noted that the data in the main cloud storage system and the backup cloud storage system are synchronous, and the number of the backup cloud storage systems may be one or multiple. The mode-the setting has the advantages that when the media content in the main cloud storage system is lost, the media content can be acquired from the backup cloud storage system; in addition, the media contents in the main cloud storage system and the backup cloud storage system can be compared, and tampering behaviors of the media contents can be timely discovered and stopped.

And secondly, when the content library is a cloud storage system, the operation authority can be set for the media content after the media content is uploaded to the content library. The operation right may be only read and forward right but not write right for the media content stored in the content library. The second mode has the advantages that the requirements of users for reading and forwarding the media content can be met, and the media content can be prevented from being tampered.

S102, the private key of the block chain account of the media creator is adopted to sign the media content, and the private key signature of the media content is obtained.

The media creator of the present application registers a blockchain account in a blockchain network, and further has a pair of public and private keys of the blockchain account, where the pair of public and private keys may be distributed by the blockchain network when the media creator registers the blockchain account, and in order to improve the security of the key, the pair of public and private keys may also be locally generated by the media creator according to a preset key generation algorithm.

Optionally, in this embodiment of the application, when the media content creator performs S101 to upload the media content to the content library, the media content creator needs to use the private key of the block chain account to sign the media content originally created this time, so as to obtain the private key signature of the media content. The specific signing process may be to use a private key of the media creator and the media content to be signed as input data, and call and run a program code related to the private key signature, so as to complete the signature of the media content and obtain the private key signature of the media content.

S103, generating a medium uplink transaction request according to the private key signature of the medium content, and sending the medium uplink transaction request to the block chain for uplink storage, so that when the medium transfer party transfers the medium content from the content library, the qualification of the medium creation party is verified according to the private key signature of the medium content stored in the block chain.

The medium uplink transaction request in the present application may be a transaction request generated by a medium content creator invoking an intelligent contract and used for requesting a blockchain network to uplink store a private key signature of the medium content contained in the medium content request. The media transshipper may be a media publisher that transships media content that others have published.

Optionally, in this embodiment of the application, after generating a private key signature for the media content of the current original creation, the media creator invokes an intelligent contract, and generates a media uplink transaction request including the private key signature of the media content according to the private key signature of the media content generated in S101, and sends the media uplink transaction request to the blockchain network. And the nodes in the blockchain network receive and execute the medium uplink transaction request, acquire the private key signature of the medium content contained in the medium uplink transaction request as transaction data and store the transaction data in the blockchain network. When a subsequent media transfer party needs to transfer the media content, the media transfer party can obtain the private key signature of the media content from the blockchain, verify the qualification of the creator of the media content according to the obtained private key signature of the media content, and if the verification is passed, the media transfer party can obtain the media content from the content library to execute the transfer operation. Optionally, the media reprinting party may obtain a public key of the media publishing party corresponding to the private key signature of the media content in the local or blockchain network, and then verify the private key signature by using the public key, if the verification is successful, it is indicated that the qualification of the media creating party is verified to be valid, that is, the media content is created by the media creating party.

Optionally, in the present application, the media uplink transaction request generated by the media authoring party may include, in addition to the private key signature of the media content described above, an identifier of the media authoring party (such as an account name and an account public key of the media authoring party), an association relationship between the media content and its private key signature, and the like. Correspondingly, when the block chain network node performs chain storage on the private key signature of the media content, the identification of the media creator and the incidence relation between the media content and the private key signature thereof are stored together, wherein the identification of the media creator stored in the block chain can be used for determining the media creator of the media content corresponding to the private key signature, and further acquiring the public key of the media creator to verify the private key signature, namely verifying whether the media content to be transferred by the media transfer party is created by the media creator. The incidence relation between the media content stored in the block chain and the private key signature thereof can be used for quickly positioning and acquiring the media content from the content library according to the private key signature of the media content.

Optionally, the media creator in the embodiment of the present application may be a network media; the medium transfer party may be a converged medium, wherein the network medium may be a qualified medium registered on the network platform, and may be, for example, a newcastle network, a people network, and the like. The integrated media can be a novel media which makes full use of media carriers, integrates different media with common points and complementarity such as broadcasting, television, newspaper, network and the like comprehensively in the aspects of manpower, content, propaganda and the like, and realizes 'resource integration, content integration, propaganda integration and benefit integration'. The scheme of the application is applied to the network media for creating the media content and the fusion media scene for transshipping the media content, so that the source of the media content can be effectively verified when the fusion media transships the media content created by the network media, the development of the fusion media can be better promoted, and the fusion media can be used for pushing the media content created by other network media safely.

According to the technical scheme of the embodiment, when a medium authoring party has authoring requirements of medium contents, the medium authoring party uploads the authored medium contents to a content library, and simultaneously signs the medium contents by using a private key of the medium authoring party to obtain the private key signature of the medium contents for uplink storage, so that when the medium transferring party needs to transfer the medium contents, the qualification of the medium authoring party can be verified through the private key signature corresponding to the medium contents stored in a block chain. The situation that the medium transfer party transfers the false medium content is greatly avoided, and the public trust of the medium transfer party is further improved.

Second embodiment

Fig. 2 is a flowchart of a media content processing method based on a blockchain according to a second embodiment of the present invention, which is further optimized based on the first embodiment and adds a process of linking up an identification of a media creator, as shown in fig. 2, the method may specifically include:

s201, the private key signature of the identity information is obtained by adopting the private key of the block chain account of the medium creator to sign the identity information of the medium creator.

In the present application, the identification information may be related information used by the media creator to prove its identity, for example, if the media creator is a qualified media unit, such as xinhua network, the related information for proving its identity may be a license of the media, a certificate covered with a unit official seal, and the like.

Optionally, in this embodiment of the application, the media creator may sign the identification information by using the private key of the blockchain account when registering the blockchain account, so as to obtain the private key signature of the identification information. The specific signing process may be that the private key of the medium authoring party and the identification information thereof are used as input data, and the related program code signed by the private key is called and run, so that the signature of the identification information can be completed, and the private key signature of the identification information thereof can be obtained.

S202, generating a qualification certification transaction request according to the identity certification information and the private key signature of the identity certification information, and sending the qualification certification transaction request to the block chain for uplink storage, so that the medium transfer party verifies the qualification of the medium creation party according to the identity certification information and the private key signature of the identity certification information stored in the block chain.

The qualification certification transaction request in the application may be a transaction request generated by a media content creator invoking an intelligent contract and used for requesting the blockchain network to uplink store the identity certification information and the private key signature thereof included in the media content creator.

Optionally, in this embodiment of the application, after generating the private key signature for the identity information of the media authoring party, the media authoring party invokes the intelligent contract, and generates a qualification certification transaction request including the identity information of the media authoring party and the private key signature thereof according to the identity information of the media authoring party and the private key signature of the identity information generated in S201, and sends the qualification certification transaction request to the block chain network. And the nodes in the block chain network receive and execute the qualification certification transaction request, acquire the identity certification information and the private key signature thereof contained in the qualification certification transaction request as transaction data and store the transaction data in the block chain network.

Optionally, when the node in the blockchain network performs uplink storage on the identification information and the private key signature thereof, an implementable manner may be that the blockchain node performs the uplink storage directly without performing identification information verification, a subsequent media transfer party needs to transfer the media content, and when verifying the qualification of the media creator of the media content, the identification information of the media creator and the private key signature thereof stored in the blockchain need to be verified; specifically, whether the identification information is accurate or not can be checked, if so, it indicates that the identification information uploaded by the medium authoring party has no problem, at this time, the public key of the medium authoring party corresponding to the private key signature of the medium content is obtained from the local or blockchain network, and then the public key is adopted to verify the private key signature of the identification information, so as to verify whether the public key uploaded by the medium authoring party when the medium authoring party issues the medium content is accurate or not. Another alternative may be that the blockchain network node performs an accuracy verification of the identification information, and if the verification is successful, performs an uplink storage operation of the identification information and its private key signature, since the identification information of the medium creator has already been verified, therefore, when the subsequent media transfer party needs to transfer the media content and verify the qualification of the media creator of the media content, can check whether the block chain network has the identification information of the medium creator without verifying the accuracy of the identification information, if yes, obtaining the public key of the media creator corresponding to the private key signature of the media content from the local or blockchain network, and then, the public key is adopted to verify the private key signature of the identification information, and whether the uploaded public key is accurate when the medium creator releases the medium content is verified.

It should be noted that, in the present application, the public and private keys of the media creator may be locally generated by the media creator itself, so as to avoid a malicious node itself generating a pair of public and private keys to falsely pretend that a qualified creator issues false media content, the introduced media reprinting party verifies the qualification of the media creator according to the identification information stored in the block chain and the private key signature thereof, and the main purpose is to verify whether the public key published when the media creator of the current media content to be reprinted issues the original media content is really a real creator with the qualification. After the subsequent execution of S205, the medium upload party generates a medium upload transaction request according to the private key signature of the medium content, and sends the medium upload request to the block chain for upload storage, and the medium transfer party verifies the qualification of the medium authoring party according to the private key signature of the medium content stored in the block chain, so as to verify whether the medium content to be transferred is published by the medium authoring party corresponding to the published public key.

S203, if the creation requirement of the media content exists, the media content is uploaded to a content library.

S204, the private key of the block chain account of the media creator is adopted to sign the media content, and the private key signature of the media content is obtained.

S205, according to the private key signature of the media content, a media uplink transaction request is generated and sent to the block chain for uplink storage, so that when the media transfer party transfers the media content from the content library, the qualification of the media creation party is verified according to the private key signature of the media content stored in the block chain.

According to the technical scheme of the embodiment, a medium creator needs to sign an identity certificate by using a private key of the medium creator to obtain a private key signature of identity certificate information, and stores the identity certificate and the private key signature thereof in a chain; when the media creator needs to upload the created media content to the content library, the private key of the media creator is used to sign the media content, and the private key signature of the media content is obtained for uplink storage. The situation that the medium transfer party transfers the false medium content is better avoided, and the public trust of the medium transfer party is improved.

Sixth embodiment

Fig. 6 is a flowchart of a media content processing method based on a blockchain according to a sixth embodiment of the present application. The embodiment is optimized on the basis of the above embodiment, and provides a preferred example for realizing the media content processing process based on the block chain when a network media is used as a media creator and a converged media is used as a media reprinter. As shown in fig. 6, the method may include:

s601, the network media adopts the private key of the block chain account to sign the self identification information to obtain the private key signature of the identification information.

For example, assuming that the network media is a news media with higher qualification, such as the xinhua network, the network media may use the private key of the blockchain account thereof to perform private key signature on the certificate of business, the certificate of the unit official seal, and the like as the identification information, so as to obtain the private key signature of the identification information.

S602, the network media generates a qualification certification transaction request according to the identification information and the private key signature of the identification information, and sends the qualification certification transaction request to the block chain for uplink storage.

For example, the network media may invoke an intelligent contract according to its own identification information and the private key signature generated in S601, generate a qualification certification transaction request, and send the qualification certification transaction request to the blockchain network, so as to request the blockchain node to uplink and store the identification information of the network media and the private key signature of the identification information.

S603, if the network media has the creation requirement of the media content, the media content is uploaded to a content library.

Illustratively, when the network media needs to report a sole news message 1, the news message 1 can be uploaded to the content library according to the method described in the above embodiment.

S604, the network media signs the media content by using the private key of the block chain account of the network media to obtain the private key signature of the media content.

For example, after the network media uploads the news message 1 to the content repository, the network media needs to use its private key to sign the news message 1 with the private key, so as to obtain the private key signature of the news message 1.

S605, the network medium generates medium uplink affair request according to the private key signature of the medium content, and sends the request to the block chain network for uplink storage.

For example, the network media may invoke an intelligent contract according to the private key signature generated in S604, generate a medium uplink transaction request, and send the medium uplink transaction request to the blockchain network, so as to request the blockchain node to uplink and store the private key signature of the news message 1 issued by the network media this time.

S606, if the media has the transfer requirement of the media content, the private key signature of the media content, the identification information of the network media to which the media content belongs and the private key signature of the identification information are obtained from the block chain.

Illustratively, if the converged media needs to forward the news message 1, it needs to verify the identity of the network media that published the news message 1. Specifically, the private key signature of the news message 1 and the private key signature of the identification information of the publisher of the news message, i.e., the network media performing the operations S601-S605, may be obtained by interacting with the tile link node.

S607, merging the media according to the private key signature of the media content, the identity information of the network media and the private key signature of the identity information, and verifying the qualification of the network media.

For example, the convergence media verifies whether the public key of the network media acquired by the convergence media is the public key of the news media with higher qualification according to the identification information of the network media acquired in S606 and the private key signature of the identification information, and if so, may verify the private key signature of the acquired news message 1 through the public key to verify whether the news message 1 is published by the network media.

S608, if the qualification of the network media is passed through by the media-fusing verification, the media content is obtained from the content library.

For example, after the network media qualification check of the news message 1 is passed, the converged media can know that the news message 1 is really published by the network media, and the network media is media with higher qualification and high public trust, so that the published news message has higher reliability, and the news message 1 can be obtained from a content library.

And S609, the converged media executes the transshipment operation after adding the network media information into the media content.

For example, in order to trace back the source of the news message 1, the converged media may add information of the network media that compose the news message 1 to the news message 1, such as adding "forward from newcastle" to the title of the news message 1, or add newcastle watermark to the news content page, and then perform a transshipping operation on the news message 1 to which the network media information is added.

S610, the converged media generates an ul transaction request including a media content transfer behavior, and sends the ul transaction request to the blockchain for ul storage.

For example, in order to trace the upload operation behavior and implement the propagation and topology process of the recording medium content, after the upload operation of the news message 1 in S609 is performed, the convergence medium needs to store the upload behavior of the current upload news message 1 into the blockchain, specifically, an uplink activity transaction request including the current upload behavior of the convergence medium is generated and sent to the blockchain network, so as to request the blockchain node to respond to the uplink activity transaction request, and store the upload behavior of the news message 1 included in the uplink activity transaction request as the transaction data in the blockchain.

According to the technical scheme of the embodiment, the network media is used as a media creating party, the converged media is used as a media transferring party, and the specific implementation processes of creating the media contents of the network media and transferring the media contents created by the network media by the converged media are provided. When the fusion media is used for transferring the original media content of the network media, the qualification of the network media can be verified, so that the fusion media can be used for pushing the media content created by other network media with confidence, and the development of the fusion media can be better promoted.
