Abstract

The embodiment of the invention relates to a blockchain evidence storage method, an evidence collection method and an evidence collection system. The method comprises the steps: obtaining evidence storage data uploaded by a user, wherein the evidence storage data comprises file feature information of an evidence storage file and user information; uploading the evidence storage data to a user evidence storage block chain to enable the user evidence storage block chain to generate a block corresponding to the evidence storage data, and enabling the user evidence storage block chain to generate block feature information of the block; and determining that evidence storage of the evidence storage data succeeds according to the block feature information. Therefore, only the file feature information of the evidence storage file is stored in the device for realizing the method, and the evidence storage file does not need to be stored; the data security of an evidence storage file can be ensured, the file is prevented from being tampered, and the privacy of a user is effectively ensured; meanwhile, a system for realizing the method in the embodiment does not need to store a storage certificate file, so the storage load of the system can be greatly reduced, and the related hardware cost is reduced.

Description

technical field [0001] The present application relates to the technical field of blockchain, and in particular to a blockchain certificate storage method, evidence collection method and system. Background technique [0002] The certificate deposit system of the blockchain is to meet the needs of customers for electronic data deposit certificates, and it is involved in the deposit and preservation of electronic data from the beginning of the electronic data life cycle. It is fixed when the electronic data is generated, and the real-time integrity of the electronic data is transmitted to the servers of judicial identification, auditing, notarization, and arbitration institutions at the first time, so that these institutions can verify the originality of a certain electronic data at any time in the future , Authenticity, once the evidence information of the electronic contract is stored during the signing process, no party can tamper with it. [0003] The evidence storage syst...
