Abstract

One or more embodiments of the invention disclose an evidence obtaining method and device based on a block chain, and the method comprises the steps: obtaining a network evidence obtaining request ofa user, and obtaining evidence obtaining identification information according to the network forensics request; calling an intelligent contract deployed on a block chain, and controlling nodes in theblock chain to execute evidence obtaining operation according to the evidence obtaining identification information to obtain corresponding evidence obtaining data; and signing the evidence obtaining data, and sending the signed evidence obtaining data to the terminal of the user. According to one or more embodiments of the invention, automatic acquisition of evidence obtaining data is realized, the evidence obtaining time is greatly shortened, the evidence obtaining efficiency is improved, meanwhile, the manpower cost of evidence obtaining is reduced. In addition, the credibility of the network environment and the credibility of the evidence obtaining data are also ensured.

Description

technical field [0001] This specification relates to the field of computer technology, and in particular to a blockchain-based evidence collection method and device. Background technique [0002] With the popularity of the Internet, cyber crimes are also increasing. To fundamentally solve cybercrime, we must rely on the law and use effective legal means to sanction cybercrime. Among them, network forensics has become one of the key issues in combating cybercrime. [0003] At present, the process of network forensics includes: the notary conducts network operations on the computer of the justice office to obtain the forensic data, and at the same time, in order to ensure the credibility of the forensic data, the notary personnel are screen-recorded throughout the process of obtaining the forensic data. [0004] However, in the above methods, on the one hand, due to the need for impartial personnel to perform network operations to obtain forensic data, it takes a long time t...
