Description
Technical field
The invention belongs to picture copyright protection technology field, it is related to a kind of picture copyright statement and guard method, specifically relates to
And a kind of picture copy-right protection method and system based on block chain technology.
Background technology
The opening of network is come from, picture is reprinted on internet and robber's figure is not needed too many technology content, in picture
In communication process, the copyright of picture author cannot preferably be stated and protected.This patent proposes a kind of based on block chain skill
The picture copyright statement that can not be distorted and guard method that art is realized.
The technical scheme of prior art one：When issuing image content such as Sina weibo, can be micro- plus oneself on picture
Rich ID and the digital watermarking of microblogging address.Above-mentioned technical proposal one utilizes PS technologies and de-watermarked instrument, can easily remove figure
Digital watermarking on piece, during subsequent propagation, it is impossible to trace back to picture author, the copyright of author cannot be stated and protected
Shield.
The technical scheme of prior art two：Flickr authorizes the picture of protection user's issue using Creative Commons
Copyright, the picture that can provide original image and multiple resolution versions is downloaded.The shortcoming of above-mentioned technical proposal two：Picture is used
After person downloads the picture for authorizing, if being unsigned picture author, during subsequent propagation, it is impossible to review picture author, author
Copyright cannot be stated and be protected.
Hash (Hash) algorithm, i.e. hash function.It is a kind of one-way cipher system, i.e., it is one from plaintext to ciphertext
Irreversible mapping, only ciphering process do not have decrypting process.Meanwhile, hash function can pass through the input of random length
Cross the output that change is fixed length later.The feature that this characteristic of unidirectional and output data length of hash function are fixed makes
Obtaining it can generate message or data.The binary value of random length is mapped as hash algorithm the two of shorter regular length
Hex value, this small binary value is referred to as cryptographic Hash.Cryptographic Hash is that one piece of data is unique and extremely compact numerical value represents shape
Formula.If hashing one section of plaintext and even only changing a letter of the paragraph, subsequent Hash will all produce different values.
It is two different inputs of same value to find hash, is computationally impossible, so the cryptographic Hash of data can be with
The integrality of inspection data.It is generally used for quick lookup and AES.
The concept of bit coin (BitCoin) was initially proposed in 2009 by middle acute hearing, is designed according to the middle thinking of acute hearing and sent out
The open source software of cloth and construction P2P networks thereon.Bit coin is a kind of digital cash of P2P forms.With most of currency
Difference, not against specific currency authority releases, it is produced bit coin according to special algorithm by substantial amounts of calculating, bit coin warp
Help using the distributed data base of numerous node compositions in whole P2P networks to confirm and record all of trading activity, and make
Money flow links security is designed to ensure that with cryptography.The decentralization characteristic of P2P in itself can be true with algorithm
Protect artificially cannot manipulate value of money by a large amount of manufacture bit coin.Design based on cryptography can make bit coin true
Owner transfer or pay.This also ensures that the anonymity of currency ownership and negotiation.Bit coin is virtual with other
The maximum difference of currency, is that its total quantity is very limited, with extremely strong scarcity.The money-system once only had not in 4 years
More than 10,500,000, total quantity afterwards will be forever limited in 21,000,000.
Bit coin is the electronic cash of similar Email, and both parties need " the bit coin wallet " of similar E-mail address
With " the bit coin address " of similar e-mail address.As sending and receiving e-mail, transferor passes through computer or smart mobile phone, by receipts
Other side is directly paid by bit coin in money side address.Following form, lists the part net of free download bit coin wallet and address
Stand.
A string of characters that bit coin address is about 33 bit lengths, be made up of letter and number, always by 1 or 3 beginnings,
Such as " 1DwunA9otZZQyhkVvkLJ8DV1tuSwMF7r3v ".Bit coin software can automatically generate address, generate address
When also without networking exchange information, can carry out offline.Bit coin address and private key are that occur in pairs, and their relation is just
As bank's card number and password.Bit coin address is used for recording you have how many bit on the address just as bank's card number
Coin.You can be random generation bit coin address deposit bit coin.Can all there be a phase each bit coin address in generation
The private key of the corresponding address is generated out.This private key may certify that you have ownership to the bit coin on the address.
We simply can understand bit coin address turns into bank card number, and the private key of the address understands turns into corresponding bank card number
Password.Only you could use the money on bank's card number in the case where bank cipher is known.So, using bit coin money
Your address and private key please be keep during bag.
After the transaction data of bit coin is packaged into one " data block " or " block " (block), even if transaction is preliminary
Confirm.After block is linked to previous block, trade fair is further confirmed.Being continuously available, 6 blocks are true
After recognizing, this transaction is substantially just irreversibly confirmed.Bit coin peer-to-peer network by all of transactions history all
It is stored in " block chain " (blockchain).Block chain is once added in block chain in lasting extension, and new block, just
Will not be removed again.Block chain is actually the scattered user endpoints of a group, and the distributed number being made up of all participants
It is the record to all bit coin transactions histories according to storehouse.Middle acute hearing is, it is expected that after data volume increase, user terminal wishes these
Data are not stored all in the node of oneself.In order to realize this target, he is using introducing hash function mechanism.Such user
End is possible to automatic rejection and falls those parts for oneself taking less than forever, and for example some bit coin transaction of extremely early stage is remembered
Record.
