Description
Technical field
Card and forensic technologies field are deposited automatically the invention belongs to webpage more particularly to a kind of webpage based on block chain is automatic
Evidence collecting method and system.
Background technique
Since the electronic data in network behavior has the characteristics that be difficult to trace to the source, easily distorts, some illegal enterprises and electricity
The product introduction that quotient operator can provide false enterprise qualification in operation, exaggerate, wherein trans-regional, cross-platform commodity transaction
Unlawful practice is especially serious, and netizen is caused easily to be spoofed, be deceived, and generates huge economic loss.In face of day
Become the online transaction dispute and network fraud phenomenon of rising, and law enforcement agency of government is located for commodity fraud, false propaganda etc.
When penalizing, there are electronic evidences to be difficult to legal, timely collection, while the public credibility of evidence is insufficient, has seriously affected administrative law enforcement power
Degree.
From report is connected to judicial expertise report is received, intermediate link is more for traditional administrative law enforcement, is easy delay evidence obtaining
Opportunity.As shown in fig. 1, it during conventional law enforcement evidence obtaining, when law enforcement agency receives network illegal report 1, needs first from mutual
Data acquisition 2 is carried out to corresponding web page in networking and evidence fixes 3.When confirming that the webpage fact of malfeasance is set up, need to department
Method appraisal organization proposes judicial expertise request 4, and judicial expertise mechanism needs re-start evidence-gathering 5 from internet, then
Evidence is carried out again and fixes 6, finally provides judicial expertise report 7 to law enforcement agency.Law enforcement agency need labor intensive, the time at
The manual of this progress evidence collects and fixes, and the evidence being collected into lacks public credibility and judicial effect, in punishment illegal operators
When be often subject to query and deny.It carries out the preservation of evidence and provides judicial expertise reporting when seeking regular judicial expertise mechanism
When, judicial expertise mechanism needs to carry out the acquisition again of evidence, verifying, during which will appear raw page data and is modified, replaces
Possibility, easily miss an opportunity because of a delay, influence the quality and efficiency of administrative law enforcement.
In addition, the evidence craft fixing means existing due to law enforcement agency, it is difficult to guarantee the fixed authenticity of electronic data,
Also it cannot achieve can verify that for evidence, be difficult to prove one's own innocence during actual evidence is fixed, collected evidence.
Summary of the invention
To overcome above-mentioned the deficiencies in the prior art, present disclose provides a kind of webpage automatic evidence-collecting methods based on block chain
And system.By the tracing to the source of dedicated forensic tools and block chain technology, can not tamper, to guarantee the true of electronic evidence
Property, verifiability and legitimacy.
To achieve the above object, the disclosure adopts the following technical scheme that
A kind of webpage automatic evidence-collecting method based on block chain, comprising the following steps:
Law enforcement agency's terminal receives network report information, carries out evidence number according to the web page interlinkage that the report information is directed to
Exclusive identification code is generated according to collection, and for the proof data；
Generate the corresponding finger print information of the proof data；The proof data is stored in data server；
Block chain is written into the identification code and finger print information, and records its location information in block chain.
Further, the method also includes:
The identification code and location information are sent to evaluation department's terminal by law enforcement agency's terminal；

Breath；The finger print information obtained from block chain is compared with the new finger print information, if comparison result is consistent, to law enforcement
Departmental terminals send probation report.
Further, the proof data, which is collected, includes:
Forensic tools are called, the webpage are converted into image data, and download information paper relevant to the webpage,
Webpage URL, image and file size, routing iinformation and acquisition time are recorded simultaneously, obtains proof data.
Further, before calling forensic tools to carry out proof data acquisition, legitimacy also is carried out to the forensic tools and is tested
Card.
Further, the legitimate verification includes: to compare the cryptographic Hash of the forensic tools original document and used
Forensic tools cryptographic Hash.
Further, before generating finger print information, whether consistent with the source data of the webpage proof data is also verified.
Further, include: by the identification code and finger print information write-in block chain
The identification code and finger print information are sent to block chain network by block chain node；
The information that block chain network carries out the identification code and finger print information propagate with it is synchronous；
The accounting nodes of block chain handle the identification code and finger print information, and are written in the block data of block chain.
One or more embodiments additionally provide a kind of terminal device, are applied to law enforcement agency, execute following steps:
Law enforcement agency's terminal receives network report information, carries out evidence number according to the web page interlinkage that the report information is directed to
Exclusive identification code is generated according to collection, and for the proof data；
Generate the corresponding finger print information of the proof data；The proof data is stored in data server；
Block chain is written into the identification code and finger print information, and records its location information in block chain；
