Description
Technical field
This application involves EDP technology field more particularly to a kind of electronic data evidence obtaining method and systems.
Background technique
With growth of the development and people of information technology in life to all kinds of information service demands, increasingly
More behaviors under line by switching on line, and thus generated electronic data is also provided with evidential effect more and more.However net
Network information itself has mutability, instantaneity, and the mode collected evidence must be legal, must be fixed after evidence-gathering
And it can be proved to, therefore the problem of electronic data evidence obtaining and keeping is field technical staff technical problem urgently to be resolved.
Currently for the method for obtaining evidence, it is equipped with private server, wireless terminal communicates therewith；Wireless terminal obtains electricity
It obtains corresponding position and or temporal information simultaneously when subclass multi-medium data and integrates, and be sent to server in time,
By server record and save terminal transmission electrical type data and save corresponding position and or temporal information.This method benefit
Solves the problems, such as electronic evidence storage with server, by third-party server storing data to guarantee to upload the complete of data
Property, by save corresponding position and or time-proven evidence upload time and place.But this method not can solve electricity still
The problem of sub- evidential effect is concentrated mainly on the following: 1, the upload of evidence is completed by user, and server only provides evidence
Storage service, can not identify whether uploaded is original unmodified data.2, user can directly access data and deposit
Server is stored up, due to a possibility that storage server can be accessed in many ways, and storage server is attacked increase, makes data storage clothes
Information Security on business device is greatly reduced.3, it does not propose highly-safe and conveniently and efficiently transfers card from storage server
According to and evidence notarization means.4, the patent is poorly suited for use in saving from damage for webpage evidence, because webpage evidence is except infringement
Outside the page, there may be a large amount of associating web pages under same domain name, if can not all save related pages from damage, are proving evidence effect
It can have a greatly reduced quality when power, but due to associating web pages substantial amounts, the method efficiency for individually uploading or saving from damage by artificial means
Lowly and it is easy to appear omissions.5, checking treatment only is carried out to data during uploading evidence, does not can guarantee storage service

The inquiry code of feedback, the inquiry code are used for subsequent query processing result.
Particularly, it is illustrated in figure 6 the process flow diagram for proving affairs, Fig. 7, which is shown, proves that transaction functionality is corresponding
Topological structure schematic diagram.This method process includes:
S601, user log in host node, the evidence that proof by selection affairs subsystem and needs prove；
S602, host node assign the task to corresponding proof affairs subsystem；
S603, it was demonstrated that after affairs subsystem receives task, will be encrypted by the corresponding storage server of data storing subsystem
Data, which are sent to, proves the corresponding decryption server of transaction system；
S604 is decrypted by decryption server using user's secret key pair encryption data；
S605, it was demonstrated that affairs subsystem check module carries out MD5 verification and timestamp inspection to ciphertext data, and is sent to
Proof personnel；
S606, it was demonstrated that personnel carry out proof activity, and result is sent to storage server；
S607, it was demonstrated that affairs subsystem will demonstrate that result and inquiry code return to host node；
S608, user receive task result and inquiry code in host node.
The process ensures that proof personnel directly contact with time point, fixed evidence, meets proof things
In direct require.
Further, in embodiments of the present invention, proof information searching function is being also equipped with from node, which looks into
Ask feature capability specifically: the inquiry instruction that host node is sent is received from node, and obtains inquiry code in inquiry instruction, according to
Inquiry code determines the corresponding processing result of inquiry code in storage server, processing result is fed back to host node, so that main section
Point shows processing result by display interface.
Particularly, being illustrated in figure 8 proves that information query processing flow chart, Fig. 9 show proof information searching function
Corresponding topological structure schematic diagram.This method process includes:
S801, user is in host node input inquiry code；
Inquiry code instruction is simultaneously sent to corresponding proof information Query Subsystem by S802, host node parsing inquiry code；
S803, it was demonstrated that result is back to host node according to inquiry code by information Query Subsystem；
S804, user check result at host node interface.
The embodiment of the invention provides a kind of distributed electrical subdata evidence collecting methods, provide electronics by this method for user
