Fig. 1 is shown to flow according to disclosed in the carrying out series digit file on block chain of one example embodiment of the disclosure
Cheng Tu:
Step S100: when receiving the request of open digital document, the trusted timestamp of the digital document is obtained；
Step S110: last open the generated exchange of digital document is obtained in the block hash value of block；
Step S120: the transaction hash value of last open the generated transaction of digital document is obtained；
Step S130: it is corresponding described that the trusted timestamp and the last open digital document are generated into transaction
Block hash value, the transaction hash value, are written the presumptive area of the digital document；
Step S140: the digital document is carried out to disclosure on block chain.
In the following, series digit file will be carried out to disclosure on block chain to above-mentioned in this example embodiment in conjunction with attached drawing
Each step carry out detailed explanation and explanation.
In the step s 100, when receiving the request of open digital document, the trusted time of the digital document is obtained
Stamp.
Trusted timestamp, which refers to, demonstrate,proves the timestamp that the digital document is issued by third party's trusted timestamp certification authority
It is bright.
Although block is the timestamp for having oneself in block chain, the timestamp of block demonstrates the generation of block
Time not can prove that the generation time of digital document.Therefore, by carrying out trusted timestamp certification to digital document, so that institute
The generation time for stating digital document can have legal effect.
In one embodiment, as shown in figure 3, step S100 includes:
Step S1001: abstract operation is carried out to the digital document, obtains corresponding digest value；
Step S1002: by the digest value and timestamp certification request, it is sent to third party's trusted timestamp certification machine
Structure；
Step S1003: the trusted timestamp that third party's timestamp certification authority generates the digital document is received.
In one embodiment, after carrying out Hash operation to the digital document, corresponding hash value is obtained.By the Hash
It is worth and timestamp certification request is carried out to the digital document, sends jointly to third party's trusted timestamp certification authority.It is described
Third party's trusted timestamp certification authority connects national time service center, therefore can be according to the international standard for receiving digital document
Time carries out timestamp certification to digital document, and the timestamp is returned to user.The timestamp proves third party
Trusted timestamp certification authority receives the time point of corresponding digital document, has legal effect.
In step s 110, last open the generated exchange of digital document is obtained in the block hash value of block.
Once to trade due to disclosing digital document every time all, same user during disclosing a series of digital documents,
His user is also in the disclosure for carrying out digital document.Therefore, a series of digital documents of same user will disperse in different areas
In block.
By this method, other users is enabled to generate the corresponding institute of transaction according to last time open digital document
Block hash value is stated, the block where last open digital document is found.
In one embodiment, as shown in figure 4, step S110 includes:
Step S1101: determine whether this is first time open digital document；
Step S1102: if it is first time open digital document, then the last open digital document is generated into friendship
The block hash value of block is determined as NULL where easily.
Since if this is first time open digital document, just without so-called last disclosure digital document, therefore,
Last time open the generated exchange of digital document when digital document that first time is open determines in the block hash value of block
For NULL.
In the step s 120, the transaction hash value of last open the generated transaction of digital document is obtained.
Due to what is be made of in a block multiple transaction, in this way, obtaining other users being capable of root
The corresponding digital document is found according to the transaction hash value.
In one embodiment, as shown in figure 5, step S120 includes:
Step S1201: determine whether this is first time open digital document；
Step S1202: if it is first time open digital document, then the last open digital document is generated into friendship
Easy transaction hash value is determined as NULL.
Since if this is first time open digital document, just without so-called last disclosure digital document, therefore,
The transaction hash value of last time open the generated transaction of digital document when digital document that first time is open is determined as NULL.
In step s 130, the trusted timestamp and the last open digital document are generated trade it is corresponding
The block hash value, the transaction hash value, are written the presumptive area of the digital document.
By this method, so that meeting timestamp with legal effect and each public affairs to the disclosure of digital document
It being capable of forward-backward correlation between the digital document opened.
In one embodiment, the last time that will acquire, open digital document generated the corresponding block Hash of transaction
The presumptive area of this digital document is written in value, transaction hash value, such as: in the file header of digital document.And it will be to this number
The presumptive area of digital document is also written in the trusted timestamp of word file, such as: the end of digital document.In this way, other users
When checking the digital document disclosed, the generation time of the digital document can be confirmed by trusted timestamp；Together
When, it can first be found according to the block hash value of last time open the generated transaction of digital document in the digital document
Block where last time open digital document generates friendship further according to the last time open digital document in the digital document
Easy transaction hash value finds last open digital document transaction generated.In this way, other users can be according to obtaining
The digital document taken finds digital document disclosed in the digital document corresponding last time.
Such as: a digital document discloses the chapter 5 of a novel, by the fate for checking the digital document
Domain learns that the block hash value of last open the generated transaction of digital document is " DEx3hkh4ldfG6OIK ", trade Hash
Value is " fDK9v4loMH18khaR ".Then, other users can therefrom be learnt, be in block hash value
In the block of " DEx3hkh4ldfG6OIK ", transaction hash value is that digital document disclosed in " fDK9v4loMH18khaR " is exactly
The chapter 4 content of the novel.
In one embodiment, if presumptive area, corresponding last open digital document are given birth in the digital document
It is NULL at corresponding block hash value of trading, transaction hash value, then illustrates that digital document of disclosure is series digit
Digital document disclosed first in file.
In step S140, the digital document is carried out to disclosure on block chain.
By this method, purpose disclosed in carrying out the digital document on block chain has been reached.
In one embodiment, the digital document is sent to the digital document receiving node on the block chain, so that
Form of this digital document to trade realizes digital document to all user nodes in block chain to existing on block chain
It is open.
In one embodiment, as shown in fig. 6, after step S140, further includes:
Step S150: preset match is written into the block hash value of block in this open generated exchange of digital document
It sets in table, open digital document, corresponding block hash value and transaction hash value is store every time in the allocation list；
Step S160: the preset allocation list is written into the transaction hash value of this open generated transaction of digital document
In.
By this method, allow when disclosing digital document next time from allocation list, obtain this open number
Block hash value and transaction hash value of the generated exchange of file in block.
In one embodiment, this open generated exchange of digital document is written in the block hash value of block default
Allocation list in, comprising: after this open digital document, if block not yet generates, by block corresponding in the allocation list
Hash value is determined as NULL, after block generation, the block hash value is determined as this open digital document and is generated
Block hash value of the exchange in block.
It is to cope with the generation of the fact that following in this way: the friendship generated after last time open digital document
It is easily not yet packaged into a block and carries out disclosure, after sending this digital document, transaction corresponding to this digital document,
It will be packaged in the same block with transaction corresponding to last digital document.In this case, since the last time is open
Digital document transaction generated has not determined block where it, therefore corresponding block hash value is not known yet.At this moment, it configures
The corresponding block hash value of the last time shown in table open digital document transaction generated is NULL, then this is written in NULL
Presumptive area in secondary disclosed digital document.And since last time open digital document generates transaction it has been determined that therefore
The corresponding transaction hash value of last time open digital document transaction generated shown in allocation list be it is determining, by the friendship
The presumptive area in digital document of disclosure is written in easy hash value.In this way, other users node receive it is of disclosure
After digital document, according in digital document presumptive area " block hash value be NULL, transaction hash value be xxx " can be true
Fixed: digital document disclosed in the last time and digital document of disclosure are in same block.Therefore, according only to transaction hash value
Digital document disclosed in the last time can be found.
In one embodiment, as shown in Fig. 2, provide it is a kind of series digit file is carried out on block chain disclosed in fill
It sets, specifically includes:
First obtains module 210, can for when receiving the request of open digital document, obtain the digital document
