Fig. 2 instantiates the flow chart of the process 200 for managing electronic data according to an example embodiment of the present disclosure.
In step 201, user generates electronic data original text (before the electronic data original text can be via its terminal device
Multimedia file, word-processing document, graphics process file, database file and program file that face is mentioned etc.) (referring to Fig. 3
In appended drawing reference 301).In one example, which may include the life for being used to indicate the electronic data original text
At the time temporal information and be used to indicate the electronic data original text generation position location information.These times it is novel and
Location information can be automatically added in the electronic data original text by terminal device.The temporal information is the current system of terminal device
Time is used to indicate the generation time of the electronic data, and the location information is by the global location on the terminal device
The location information that system (GPS) obtains, is used to indicate the generation position of the electronic data.
In step 202, signed using the private key of user to electronic data original text via the terminal device, and by its
The electronic data through user's signature is packaged into together with the associated user certificate of the user (referring to the appended drawing reference in Fig. 3
302).The electronic data through user's signature includes user's signature (i.e. the first electronics of electronic data original text, the user as a result,
Signature) and user certificate associated with the user (i.e. the first digital certificate).User's signature is based on the private key and electronics
Data original texts generates.It in one example, can be by being encoded using Hash (Hash) function to electronic data original text
Encryption forms digest value (digest), is then encrypted to the digest value using private key to generate user's signature.It is to be appreciated that logical
Crossing with the digest value that upper type obtains is safe, not modifiable on network.In one example, user certificate is by third party
Authoritative certificate authorized organization (for example, certificate authority (Certificate Authority, abbreviation CA)) signs and issues to the user
(that is, the user certificate is crossed through real-name authentication).For example, the user certificate can be by third party's authoritative certificate authorized organization at least
It is generated based on public key provided by user and is signed and issued to user.In another example, user certificate is general certificate, without
It is the certificate signed and issued by third party's authoritative certificate authorized organization.At this moment, the purpose of user's signature and user certificate is merely to reality
To the calling of electronic data on present block chain, rather than in order to which the user to electronic data is tracked, therefore electronic data
It itself is the equal of anonymous.
In step 203, it is weighed from the terminal device via network (for example, cable network or wireless network) to by third party
Prestige trusted timestamp service organization (for example, China joint trust time-stamping service center (Time Stamp Authority,
Abbreviation TSA)) provide trusted timestamp service (such as, Digital Time-stamp service (Digital Time Stamp, referred to as
DTS trusted timestamp and trusted timestamp certificate)) are requested.Trusted timestamp is the data generated using digital signature technology,
Usually a string of character strings can uniquely identify and carry out time service and the punctual believable time ensured by authoritative temporal organization,
And it can be used for proving whether relevant electronic data keeps complete from its content after application trusted timestamp, is not modified.One
In a example, trusted timestamp can generate in the following manner: generate electronic data original text using hash function by user
Digest value, then the digest value is sent to trusted timestamp service (in the present embodiment, which can be used as above by user
A part of request is sent to trusted timestamp service), trusted timestamp service will receive after receiving the digest value
Trusted time information (coming from trusted time source) when the digest value is encoded together with the digest value by specific format, is then used
The private key of the trusted timestamp service is digitally signed it, to generate trusted timestamp.It is generated in the trusted timestamp
After, third party authority's trusted timestamp service organization can sign and issue the trusted time to user via the trusted timestamp service
Stamp.Trusted timestamp certificate is associated with the trusted timestamp, can be used for verifying the validity of trusted timestamp,
And can the trusted timestamp as provided by third party authority's trusted timestamp service organization service for example, at least be based on its public key
To generate and be signed and issued to user.
Although it is worth noting that, in this example embodiment, in addition to electronic data original text carried out user's signature with
Outside, trusted timestamp signature also has been carried out to electronic data original text, but it should it will be appreciated that in actual use, only to electronics
Data original text carries out user's signature, or can also additionally to electronic data original text carry out except user's signature or trusted timestamp with
Other outer signatures, as long as the signature advantageously ensures that the integrality, validity and credibility of electronic data.
In step 204, authoritative from third party by network (for example, cable network or wireless network) by the terminal device
Trusted timestamp service organization receives requested trusted timestamp and trusted timestamp certificate.
In step 205, by received trusted timestamp and trusted timestamp certificate addition in the electricity through user's signature
In subdata, generate the electronic data signed through trusted timestamp (referring to the appended drawing reference 303 in Fig. 3).This is through credible as a result,
The electronic data of timestamp signature is in addition to including the user's signature (the first electronic signature) of electronic data original text, the user and using
Other than family certificate (the first digital certificate), should also include be used to indicate trusted timestamp signature (second electronic signature) and with
The associated trusted timestamp certificate of the trusted timestamp (the second digital certificate).
In step 206, the electronics that terminal device (for example, cable network or wireless network) will be signed through trusted timestamp
Data are sent to the block chain node in block chain network.
In step 207, block chain node, can to the warp after receiving the electronic data through trusted timestamp signature
Electronic signature in the electronic data of letter timestamp signature is verified.In one example, block chain node is receiving this
It, can be for example by utilizing its intelligent engine-operated accepting electronic data intelligence of contract after the electronic data of trusted timestamp signature
Contract to the electronic signature in the electronic data through trusted timestamp signature (user's signature and is used to indicate trusted timestamp
Signature) verified.
In one example, in the case where having carried out user's signature to electronic data original text, to this through trusted timestamp
It may include based on including in the electronic data signed through trusted timestamp that electronic signature in the electronic data of signature, which carries out verifying,
User certificate user's signature (that is, identity of user) is verified, specifically can include: to this through trusted timestamp signature
Included electronic data original text application hash function, obtains the first digest value in electronic data；Based on this through trusted timestamp
The user certificate for including in the electronic data of signature calculates the public key (the first public key) of user, and with the public key of the user to this
The user's signature for including in electronic data is decrypted, and obtains the second digest value；First digest value and the second digest value are carried out
Compare.Wherein, under the first digest value and the identical situation of the second digest value, user's signature is verified.
It in another example, can to the warp in the case where also having carried out trusted timestamp signature to electronic data original text
Letter timestamp signature electronic data in electronic signature carry out verify may also include it is credible based on signing through trusted timestamp
Timestamp certificate verifies trusted timestamp signature (that is, validity of trusted timestamp), specifically can include: can to the warp
The validity for the trusted timestamp certificate for including in the electronic data of letter timestamp signature is verified；Determining the trusted time
It stabs in the effective situation of certificate, to the electronic data original text application Hash for including in the electronic data through trusted timestamp signature
Function obtains third digest value；Based on the trusted timestamp certificate for including in the electronic data through trusted timestamp signature
It calculates corresponding public key (the second public key), and the trusted timestamp signature for including in the electronic data is solved with the public key
It is close, obtain the 4th digest value；Third digest value is compared with the 4th digest value.Wherein, it is plucked in third digest value with the 4th
It is worth in identical situation, trusted timestamp signature is verified.
In the disclosure, for example, in the case where only having carried out user's signature to electronic data original text, when the first digest value
When identical as the second digest value, it is verified.In the case where also having carried out trusted timestamp signature to electronic data original text, then
Under third digest value and the 4th digest value also identical situation, verifying just passes through.It is to be appreciated that if also to electronic data original
Text has carried out other signatures, then also needing the verifying to these other signatures, verifying just passes through in the case where.
In a step 208, in the case where the verifying to sign electronically to each passes through (for example, being tested in electronic data
The verification result that intelligent contract is returned is demonstrate,proved to sign in effective situation), block chain node stores the electronic data to area
On the account book of block chain.In one example, in the case where being verified, block chain node can send the electronic data to company
The block chain node of account book is connected to be stored.Since the data in deposit block chain can not be tampered, it is thus ensured that should
Electronic data will not be distorted during its storage by any personal and mechanism so that the electronic data can not tamper with
And the credibility as evidence can be guaranteed.
In step 209, block chain node returns to the Data Identification for being used to indicate the electronic data to terminal device.As
Example, the Data Identification may be, for example, the Hash character string of the electronic data or can ensure Data Identification uniqueness it is any its
His character string.
In step 210, verifying not in the case where (that is, to the verifying of any electronic signature not over
In the case where), illustrate that the electronic data may receive forgery or distort, therefore block chain node will return to error message.
In step 211, in the case where user needs to inquire electronic data, by terminal device to the block of block chain
Chain node sends electronic data inquiry request, with the electronic data for requesting inquiry required, can wrap in the electronic data inquiry request
Include one or more Data Identifications.
In the step 212, it after block chain node receives the electronic data inquiry request, is obtained from the account book of block chain
Take electronic data indicated by thus one or more Data Identifications.In one example, block chain node can be by utilizing intelligence
The engine-operated electronic data of energy contract inquires intelligent contract to inquire corresponding electronic data on block chain.
In step 213, the electronic data inquired is returned to terminal device by block chain node.
In conjunction with Fig. 2 embodiment illustrated it is found that in the disclosure, due to when electronic data generates just (for example, by
The private key and trusted timestamp of user) just signed to it, and signed electronic data is stored on block chain,
Ensure that electronic data can not tamper and credibility, and ensure that the electronic data can be effectively used as electronics in turn
Evidence.
