Description
Technical field
The present invention relates to electronic evidence certifications and exchange method and system technical field, specially a kind of to be based on block chain
Electronic evidence certification and exchange method and system.
Background technique
It is counted according to the China Internet Network Information Center (CNNIC), by June, 2017, China's netizen's scale reaches 7.51
Hundred million, China's mobile phone users are up to 7.24 hundred million, with the arrival in global IT application digitization epoch, are especially with trial
The deep propulsion of the criminal justice system reform of the heart, Computer forensics will become the king of the evidence of current era, in future
It is had a decisive role in juridical practice, huge netizen's scale causes more and more information extensive on the internet
It propagates, the information content that major social media generates is increased with PB grades, since most of Web information issuance is all non-system of real name,
In addition complicated netizen's ingredient provides condition without the breed and spread suspected of internet rumour.
Orderly sharing in the state that electronic evidence is not tampered is the solid guarantee of gentleman's business originally, and how
Guarantee that the electronic evidence obtained is not tampered, reaches the unified approval of each side, be basis and the indispensability of effective applying electronic evidence
Condition.
Block chain is a kind of a kind of chain type number for being sequentially in time combined into data block in such a way that sequence is connected
According to structure, and the distributed account book that can not be distorted He can not forge guaranteed in a manner of cryptography, broadly, block chain skill
Art is to verify to know together algorithm with storing data, using distributed node to generate and update number using block linked data structure
According to, the safety that guarantees in the way of cryptography data transmission and access, utilize and closed by the intelligence that automatized script code forms
The completely new distributed basis framework and calculation paradigm of one kind with operation data about is programmed, block chain format is initially used for comparing
Special coin, as the solution for solving the problems, such as database security with the administrator for not needing to trust, first piece of block chain is in
This acute hearing implements the core component as digital cash bit coin, wherein its conduct in generalities in 2008, and in next year
The open ledgers of All Activity, by using peer-to-peer network and distributed timestamp server, block chain database is by automatically
Management, the invention of bit coin block chain make it first and solve the digital cash that dual branch goes wrong, and therefore, are badly in need of one
The characteristics of kind can not be distorted using the decentralization of block chain technology, opening, autonomy, information can low cost solution " trust
Transmitting " problem, and the electronic evidence that each side's acquisition is effectively ensured is not tampered, unifies the understanding, the scheme of shared evidence.
Summary of the invention
The purpose of the present invention is to provide a kind of electronic evidence certification and exchange method and system based on block chain, should
Method using block chain technology it is inexpensive, it is anti-tamper, be divided into and enjoy, solve to growth-promoting state electronic evidence " Trust transitivity ", on demand
The evidence obtaining of multiplexing each side realizes the certification and exchange for remotely investigating electronic evidence on the spot to website as a result, can use this method, due to net
It stands update, variation, different time points web site contents, clue are different, specifically such as swindle the payment link of website orientation, electricity
Often section does not update receiving bank's account to words etc., even illegal website domain name is also replaced frequently to escape and beat for variation, gambling site
Hit, website form before has not existed, using the specific implementation of this method can be improved the integrality of evidence, proof,
Each side's evidence obtaining ability, standardized level, the collecting quantity and quality for improving electronic evidence are improved, final raising evidence obtaining personnel are real
War evidence obtaining and clue excacation efficiency and emergency response speed, to solve the problems mentioned in the above background technology.
To achieve the above object, the invention provides the following technical scheme: it is a kind of based on block chain electronic evidence certification and
Exchange method and system, application method the following steps are included:
A, authorized user compresses the electronic evidence obtained by specific algorithm or Software Compression at one or more
Packet, and calculate the HASH value of compressed package;
