Detailed Description

Exemplary embodiments of the present application will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present application are included to facilitate understanding, and are to be considered merely exemplary. 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 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 media content processing method based on a blockchain according to a first embodiment of the present application, which is applicable to a case of processing media content. The method is particularly suitable for processing the authored media content when the media creator publishes the original media content. The method may be performed by a media creator. The media creator may be a media publisher that publishes media content that is original. Alternatively, the media creator's device may or may not be a blockchain network node (e.g., may be a regular blockchain node or a lightweight node), but may interact with the blockchain network through an interface provided by the blockchain network. The method may be performed by the blockchain-based media content processing device provided by the seventh embodiment of the present application, which may be implemented in software and/or hardware and may be integrated into the media authoring device. Referring to fig. 1, the method may specifically include:

S101, if the authoring requirement of the media content exists, uploading the media content to a content library.

In the present application, the media content may be specific information transmitted by the message transmission tool, for example, news content, advertisement content, or video content. The content library may be a database storing media content that has been published. The scheme of the embodiment of the application aims at publishing the medium content on the network platform, and for the network platform, each platform can be provided with a content library for storing the medium content published on the network platform. Alternatively, the repeatedly published media content (e.g., forwarded media content) content library may be stored only once.

Optionally, in the embodiment of the present application, when the media creator wants to issue original media content on a certain network platform, after editing the original media content on an application client provided by the network platform, a sending button is clicked, and at this time, the application client will respond to a sending instruction triggered by a user to upload the media content edited by the user to a content library of a network platform at a rear end thereof, so as to issue the media content edited by the user on the network platform, and at this time, all users of the network platform can view the media content through the application client thereof.

Alternatively, in an embodiment of the present application, the content library of the storage medium content may be a cloud storage system or a blockchain 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 (Inter Planetary File System, IPFS) technology, and has the advantage of lower cost; the blockchain storage system is a storage system built by adopting a blockchain network technology, and has the advantage of higher safety and reliability. Can be selected according to actual requirements.

Optionally, when the network platform selects the cloud storage system with lower cost, in order to prevent the 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 ways:

in the first mode, when the content library is a cloud storage system, the content library is set to be a distributed main cloud storage system and a backup cloud storage system, and accordingly, 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 more. The method has the advantages that when the medium content in the main cloud storage system is lost, the medium content can be acquired from the backup cloud storage system; in addition, the tampering behavior of the media content can be found and stopped in time through the comparison of the media content in the main cloud storage system and the backup cloud storage system.

In the second mode, 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 authority may be the authority of each user for the medium content stored in the content library, which is only read and forward and not write. The second mode has the advantages that the requirement of a user for reading and forwarding the medium content can be met, and the medium content can be prevented from being tampered.

S102, signing the media content by adopting a blockchain account private key of the media creator to obtain a private key signature of the media content.

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

Optionally, in the embodiment of the present application, when the media content creator executes S101 to upload the media content to the content library, the media content creator needs to sign the media content originally created this time by using its blockchain account private key, so as to obtain the private key signature of the media content. The specific signing process can be that a private key of a media creator and media content to be signed are used as input data, related program codes of the private key signature are called and operated, and the signing of the media content can be completed, so that the private key signature of the media content is obtained.

And S103, generating a media uplink transaction request according to the private key signature of the media content, and sending the media uplink transaction request to the blockchain for uplink storage, so that when the media reprinting party reprints the media content from the content library, the qualification of the media creator is verified according to the private key signature of the media content stored in the blockchain.

The media uplink transaction request in the application can be a transaction request generated by calling the intelligent contract by the media content creator and used for requesting the blockchain network to store the private key signature of the media content contained in the request. The medium transfer party may be a medium issuer that transfers medium content that has been issued by another person.

Optionally, in the embodiment of the present application, after generating the private key signature for the media content originally created this time, the media creator invokes the intelligent contract, generates the 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. Nodes in the blockchain network receive and execute the media uplink transaction request, acquire private key signatures of media content contained in the media uplink transaction request as transaction data, and store the private key signatures in the blockchain network. When the medium transfer party needs to transfer the medium content subsequently, the medium transfer party can acquire the private key signature of the medium content from the blockchain, verify the qualification of the creator of the medium content according to the acquired private key signature of the medium content, and if the qualification passes the verification, the medium transfer party can acquire the medium content from the content library to execute the transfer operation. Optionally, the medium reprinting party may obtain a public key of the medium publisher corresponding to the private key signature of the medium 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 indicates that the qualification of the medium creator is valid, that is, the medium content is authored by the medium creator.

Optionally, in the present application, the media uplink transaction request generated by the media creator may include, in addition to the private key signature of the media content introduced above, an identifier of the media creator (such as an account name, an account public key, etc. of the media creator) and an association relationship between the media content and the private key signature thereof. Correspondingly, when the private key signature of the media content is stored in a uplink manner, the blockchain network node stores the identifier of the media creator, the association relationship between the media content and the private key signature thereof and the like in the uplink manner, wherein the identifier of the media creator stored in the blockchain can be used for determining the media creator of the media content corresponding to the private key signature, and further the public key of the media creator is obtained to verify the private key signature, namely, whether the media content to be transferred by the media transfer party is created by the media creator or not is verified. The association relation between the media content stored in the blockchain and the private key signature thereof can be used for rapidly 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, for example, a Xinhua network, a people network, etc. The medium can be a novel medium which fully utilizes a medium carrier, has common points of broadcasting, televisions, newspapers, networks and the like and has complementarity, and can comprehensively integrate the aspects of manpower, content, propaganda and the like to realize 'resource fusion, content fusion, propaganda fusion and benefit fusion'. The scheme of the application is applied to the network media for creating the media content and the fused media scene for reloading the media content, so that the source of the media content can be effectively verified when the fused media reloads the media content created by the network media, the development of the fused media can be better promoted, and the fused media can be used for pushing the media content created by other network media safely.

According to the technical scheme, when the medium creator has the creation requirement of the medium content, the medium creator uploads the created medium content to the content library, and meanwhile, the medium content is signed by adopting the private key, so that the private key signature of the medium content is obtained and stored in a uplink mode, and when the medium reprinting party needs to reprint the medium content, the qualification of the medium creator can be verified through the private key signature corresponding to the medium content stored in the blockchain. The situation that the medium transfer party transfers 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 blockchain according to a second embodiment of the present application, which is further optimized based on the first embodiment, and adds a process of linking the identity of the media creator, as shown in FIG. 2, and the method specifically may include:

s201, signing the identification information of the media creator by adopting a blockchain account private key of the media creator to obtain a private key signature of the identification information.

In the present application, the identification information may be information related to the identity of the media creator, for example, if the media creator is a qualified media unit, such as Xinhua network, the information related to the identity of the media creator may be a business license of the media, a certificate covered with a unit official seal, or the like.

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

S202, generating a qualification transaction request according to the identification information and the private key signature of the identification information, and sending the qualification transaction request to a blockchain for uplink storage so that a medium transfer party can verify the qualification of a medium creator according to the identification information and the private key signature of the identification information stored in the blockchain.

The qualification proving transaction request can be a transaction request which is generated by calling the intelligent contract by the media content creator and is used for requesting the blockchain network to store the identification information contained in the request and the private key signature thereof in a uplink manner.

Optionally, in the embodiment of the present application, after generating a private key signature for the identity information of the media creator, the media creator invokes the intelligent contract, generates a qualification transaction request including the identity information of the media creator and the private key signature thereof according to the identity information of the media creator and the private key signature of the identity information generated in S201, and sends the qualification transaction request to the blockchain network. And a node in the blockchain network receives and executes the qualification proving transaction request, acquires the identity proving information contained in the qualification proving transaction request and the private key signature thereof as transaction data, and stores the transaction data in the blockchain network.

Optionally, when the node in the blockchain network performs uplink storage on the identification information and the private key signature thereof, an embodiment may be that the blockchain node performs uplink storage directly without performing identification information verification, and when a subsequent media transfer party needs to transfer the media content and verifies the qualification of the media creator of the media content, the identification information and the private key signature of the media creator stored in the blockchain need to be verified; specifically, whether the identification information is accurate or not can be checked, if so, it is stated that the identification information uploaded by the media creator is problematic, at this time, a public key of the media creator corresponding to the private key signature of the media content is obtained from the local or blockchain network, and then the private key signature of the identification information is verified by adopting the public key, so that whether the public key uploaded by the media creator when publishing the media content is accurate or not is verified. In another embodiment, the blockchain network node performs accuracy verification on the identification information first, if the verification is successful, then performs the operation of uplink storage of the identification information and the private key signature thereof, at this time, since the identification information of the media creator is verified, the media loader needs to reload the media content, when verifying the qualification of the media creator of the media content, whether the identification information of the media creator exists in the blockchain network is checked, and the accuracy of the identification information is not required to be verified, if so, the public key of the media creator corresponding to the private key signature of the media content is obtained from the local or blockchain network, then the private key signature of the identification information is verified by adopting the public key, and whether the public key uploaded when the media creator issues the media content is accurate 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 that the malicious node generates a pair of public and private keys by itself to impersonate a certain qualification creator to issue false media content, the media transfer party verifies the qualification of the media creator according to the identification information stored in the blockchain and the private key signature thereof, and the main purpose is to verify whether the public key issued when the media creator of the media content to be transferred currently issues the original media content is really the real creator with the qualification. And after the subsequent execution of S205, a media uplink transaction request is generated according to the private key signature of the media content, and the media uplink transaction request is sent to the blockchain for uplink storage, and the main purpose when the media reloader verifies the qualification of the media creator according to the private key signature of the media content stored in the blockchain is to verify whether the media content to be reloaded is issued by the media creator corresponding to the public key issued by the media reloader.

And S203, if the authoring requirement of the media content exists, uploading the media content to a content library.

And S204, signing the media content by adopting a blockchain account private key of the media creator to obtain a private key signature of the media content.

Sixth embodiment

Fig. 6 is a flowchart of a blockchain-based media content processing method according to a sixth embodiment of the present application. The embodiment optimizes the embodiment, and provides a preferable example of realizing the media content processing process based on the blockchain when a network medium is used as a media creator and a fused medium is used as a media transfer party. As shown in fig. 6, the method may include:

s601, the network media adopts the private key of the blockchain account to sign the self identification information, and the private key signature of the identification information is obtained.

For example, assuming that the network medium is a news medium with higher qualification, such as Xinhua network, the network medium may use the private key of its blockchain account to sign the private key of its business license, the certificate of the public seal of the unit, etc. as the identity information, to obtain the private key signature of the identity information.

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

For example, the network medium may invoke the intelligent contract according to the self identification information and the private key signature generated in S601, and generate a qualification transaction request to send to the blockchain network, so as to request the blockchain link point to store the identification information of the network medium and the private key signature of the identification information in a uplink manner.

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 medium needs to report a unique news message 1, the news message 1 may be uploaded to the content repository according to the method described in the above embodiment.

And S604, the network media signs the media content by adopting the private key of the blockchain account to obtain the private key signature of the media content.

For example, after uploading the news message 1 to the content library, the network medium needs to use its private key to sign the private key of the news message 1, so as to obtain the private key signature of the news message 1.

S605, the network media generates a media uplink transaction request according to the private key signature of the media content, and sends the media uplink transaction request to the blockchain network for uplink storage.

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

S606, if the medium content is required to be transferred, the private key signature of the medium content, the identification information of the network medium to which the medium content belongs and the private key signature of the identification information are obtained from the blockchain.

Illustratively, if the converged media needs to download news message 1, it needs to authenticate the network media that published news message 1. Specifically, the interaction with the block link point may be performed to obtain the private key signature of the news message 1 and the private key signature of the publisher of the news message, that is, the identity information and the identity information of the network medium that performs the operations S601-S605.

S607, the converged medium verifies the qualification of the network medium according to the private key signature of the medium content, the identification information of the network medium and the private key signature of the identification information.

Illustratively, the converged medium verifies whether the public key of the network medium acquired by the converged medium is true or not according to the identification information of the network medium and the private key signature of the identification information acquired by the converged medium in S606, and if yes, the private key signature of the news message 1 acquired by the public key verification can be verified to verify whether the news message 1 is issued by the network medium.

S608, if the fused media verifies that the qualification of the network media is passed, the media content is acquired from the content library.

Illustratively, after the qualification of the network medium for publishing the news message 1 is verified, it is known that the news message 1 is truly published by the network medium, and the network medium is a medium with high qualification and high public confidence, so that the reliability of the published news message is high, and the news message 1 can be obtained from the content library.

S609, the fused media adds network media information into the media content and then executes the reloading operation.

For example, in order to trace the publishing source of the news message 1, the converged media may add information for creating the network media of the news message 1 to the news message 1, such as adding "forward from the new web" to the title of the news message 1, or adding a new web watermark to the news content page, and then performing a reloading operation on the news message 1 to which the network media information is added.

S610, the thawing medium generates a behavior uplink transaction request including a medium content reloading behavior and sends the behavior uplink transaction request to the blockchain for uplink storage.

For example, in order to implement tracing of the action of the reloading operation and the propagation and topology process of the content of the recording medium, after the reloading operation of the news message 1 in S609 is performed, the reloading action of the news message 1 needs to be stored in the blockchain by the fusion medium, specifically, an action uplink transaction request including the action of the reloading action is generated and sent to the blockchain network, so as to request the blockchain link point to respond to the action uplink transaction request, and the reloading action of the news message 1 further included therein is stored in the blockchain as transaction data.

According to the technical scheme, the network media is used as a media creation party, the fused media is used as a media transfer party, and specific implementation processes of the network media creation media content and the fused media transfer media content of the network media creation are provided. When the medium content created by the network medium is reloaded, the qualification of the network medium can be verified, so that the medium can be used for pushing the medium content created by other network media safely, and the development of the medium can be better promoted.
