Webpage data automatic evidence obtaining and storing method based on block chain

Abstract

The invention discloses a webpage data automatic evidence obtaining and storing method based on a block chain. A user sends a uniform resource locator of a webpage which needs evidence obtaining to all evidence obtaining nodes in a block chain network, and the evidence obtaining nodes carry out automatic evidence taking on the webpage; the evidence obtaining nodes generate a preservation certificate and a data compression package for the evidence obtaining data, and the data compression package is signed and then stored in a server, the hash value of the data compression packet is calculated,a timestamp is added, and the data compression packet is broadcast to a block chain network after being signed; the evidence obtaining nodes verify the timestamp of the hash value, and if the condition is met and the signature is not signed, the signature is signed and broadcast to the block chain network; a rule node receives the data signed by all the evidence obtaining nodes, and the signatureis verified, after verification is passed, the data are formed into blocks and broadcast to the block chain network; and the evidence obtaining nodes anchor the blocks to a public block chain. The method can be used for carrying out automatic evidence obtaining and evidence storage on webpage data, and the authenticity of the evidence taking data and the safety of the evidence storage data are ensured.
