11d801eb6ffa84fb3b2e97aab1193e23a9c2c1286e95e22bdf87488b35ddcd2e。
For example, if digital content creator A has been created a piece of music " flower ", digital content creator A is intended to think
Music " flower " is issued by internet.Firstly, digital origination person A is connected to the network based on block chain, can pass through
One website or a customer end A pp or other any modes that can be connected are connected to block chain network, and block chain network is directed to
Music " flower " creates a DH key, and DH key includes a public key and a private key, meanwhile, music is calculated using SHA256 algorithm
" flower " obtains " flower " abstract F as unique identifier.
Step 102 encrypts digital content, will be in the relevant information of the digital content of encryption and the digital content
Reach network.
Pre- distribution of digital content is encrypted in the public key of the DH key created in step 101, in block link network
The relevant information that the digital content is registered in network, as the title of digital content, issuing amount, the price of payment, publication number are related
Information and the relevant information of any distribution publication to digital content etc.；Issuing amount can be by digital content creator or number
Content distributor is arbitrarily distributed, and can also be allocated according to the content of digital content.It will be in encrypted digital content, the number
The relevant information of appearance and abstract as unique identifier are uploaded to block chain network.Specifically, digital content creator or
Digital content publisher can be connected to block chain network by proxy interface, and the correlation of digital content is registered by proxy interface
Information uploads encrypted digital content, the relevant information of the digital content by proxy interface and as unique identifier
Abstract to block chain network, which can be website or customer end A pp etc..
For example, music " flower " is encrypted using the public key of the DH key created in step 1, in net
Stand or App on fill in musical designation " flower ", issuing amount be 10 parts, 100 yuan of price paid, publication number and it is any with number
Word content distribution publishes relevant information.Specifically, issuing amount, that is, digital content number can be formulated according to digital content,
Though can have digital content creator or digital content publisher to be assigned as any number, every part of accounting can also be by number
Hold creator or digital content publisher voluntarily distributes；Every part of price can arrange price according to significance level, can also average mark
Match；Price paid can be currency, be also possible to token or integral etc. that a certain platform is voluntarily issued.
After registration, by the music " flower " of encryption, the title " flower " of registration, 10 parts of issuing amount, payment
The relevant informations such as price, and net is passed through using the abstract F after the calculating of SHA256 algorithm as unique identifier in step 1
It stands or App is uploaded to block chain network.Wherein, uploading medium can be any medium that can connect to network, can be website,
It is also possible to App, is also possible to other forms, the present invention program is not specifically limited.
If the relevant information of step 103, the digital content of the encryption and the digital content meets the requirements, according to described
Digital content submits intelligent contract information to network.
The audit of block chain network confirms the digital content of encryption uploaded, the relevant information of the digital content and as unique
Whether the abstract of identification marking meets digital content distribution specification, and inquires in the whether existing number of block chain network node
Hold, specifically, the whether existing digital content of block chain network node can be inquired by proxy interface；On the other hand, may be used
To pass through whether existing digital content of digest challenge block chain network node as unique identifier.
If the digital content of encryption, the relevant information of the digital content and the abstract as unique identifier that upload
It meets the requirements, and without the digital content in block chain network node, then intelligent contract information is constructed according to the digital content, adopted
It is signed to form the broadcast event with signature to intelligent contract information with the private key of DH key, broadcasts band signature to block chain network
Broadcast event.Wherein, which includes every publication content of digital content and the matchmaker for connecting block chain network
Jie's information.
If the digital content of encryption, the relevant information of the digital content and the abstract as unique identifier that upload
Existing digital content in undesirable or block chain network node is then refused to announce the encryption to block chain network
Digital content and public key.
For example, the music for the encryption that the medium website or customer end A pp audit confirmation for connecting network upload
" flower " content, the relevant informations such as title " flower ", 10 parts of issuing amount, 100 yuan of price paid, and use SHA256
Whether the abstract after algorithm calculating as unique identifier meets digital content distribution specification and authorized agreement, and passes through website
Or customer end A pp, to the whether existing music " flower " of block chain network querying node, specifically, can use has uniquely
" flower " abstract of identification marking passes through website or customer end A pp to the whether existing music of block chain network querying node
" flower ", can be improved search efficiency in this way.If music " flower " content uploaded, title, 10 parts of issuing amount, payment
100 yuan of price, and abstract F as unique identifier meets digital content distribution specification and authorized agreement, and block chain
Network node does not inquire music " flower ", then constructs intelligent contract information, intelligent contract information according to music " flower "
It makes a summary F including music " flower ", 10 parts of issuing amount, the information of 100 yuan of initial issue price and website or App are optional
Ground, such as title such as iqiyi.com, Himalaya.It is signed using the private key of DH key to intelligent contract information, formation has
" flower " broadcast event of signature, to " flower " broadcast event of block chain network publication with signature.
If music " flower " content uploaded, title, 10 parts of issuing amount, 100 yuan of price paid, and as only
The abstract F of one identification marking does not meet digital content distribution specification and authorized agreement or block chain network querying node to having deposited
At music " flower ", then refuse to announce the music " flower " and public key to block chain network.
Step 104 after receiving the confirmation message of network-feedback, issues the digital content and public key of the encryption.
Into block chain network, each broadcast event of the block publication with signature, each block are fed back really after receiving the broadcast event
Recognize information, after receiving the confirmation message of each block in block chain network, then issue the digital content and public key of the encryption,
Preferably, after the confirmation message for receiving at least 6 pieces of block chain safety verification blocks feedback, intelligent contract comes into force, described in distribution
The digital content and public key of encryption, digital content creator or digital content publisher possess the distribution number of the digital content of registration
Amount, can inquire the digital content in block chain network.If less than the confirmation letter of 6 pieces of block chain safety verification blocks feedback
Breath, intelligent contract is invalid, then does not issue the digital content and public key of the encryption.
For example, the block after block chain network receives " flower " broadcast event with signature, into block chain
1, block 2, block 3.Block n broadcasts " flower " broadcast event of band signature, after each block receives the broadcast event
Feeding back confirmation message, when block 1, block 2, block 3, block 4, block 5, block 6 six continuous block chain safety verification blocks are anti-
After the confirmation message of feedback, intelligent contract comes into force, then issues the digital content and public key of the encryption, the digital content, distribution
Quantity, price, the abstract written block chain account book as unique identifier.Optionally, when block 11, block 25, block
27, block 45, block 70, block 96,100 7 block chain safety verification blocks of block feedback confirmation message after, then sale room
State the digital content and public key of encryption, then digital content, issuing amount, price, have been written into as the abstract of unique identifier
Block chain account book.The present invention program does not limit the number of blocks of specific feedback acknowledgment information, as long as extra 6 pieces of blocks chain is safe
Confirm that block chain can be written in the digital content and relevant information by block.Optimal case is to receive at least 6 pieces of continuous blocks
The confirmation message of chain safety verification block feedback.
A kind of rights issuer method based on block chain that the embodiment of the present invention one provides is used by creating DH key
Public key carries out the digital content issued in advance to be distributed to block chain after encrypting and encrypting intelligent contract information using private key
In network, the review mechanism for overcoming the network platform in the prior art is unsound and dampens digital content producers and uses internet
The enthusiasm activated business, the defect for interfering information to propagate, the author for reaching digital content can be with unprecedented low cost
Mode issues their works, can be with the relatively effective effect being managed to copyright while maximumlly obtaining interests
Fruit.
