WIPO Patent Application WO/2020/238051
Kind Code:
A1
Abstract:
The present application relates to the technical field of block chains, and discloses a block chain-based electronic contract storage method and apparatus, an electronic device, and a computer non-volatile readable storage medium. Said method comprises: acquiring an electronic contract original uploaded to a block chain network, the electronic contract original being an electronic file obtained by synthesizing an electronic contract and electronic signature data of a signatory; pre-processing the electronic contract original to obtain data of the electronic contract original; encrypting the data of the electronic contract original using a pre-set encryption algorithm so as to generate a data fingerprint; broadcasting the contract serial number and data fingerprint corresponding to the electronic contract original in the block chain network, so as to perform information verification; if the information verification succeeds, adding the contract serial number and the data fingerprint to the block chain maintained by respective node in the block chain network, so that the electronic contract original can be prevented from being disclosed, the secrecy of the electronic contract original can be improved, and the electronic contract original data corresponding to the data fingerprint can also be prevented from being tampered with, thereby guaranteeing the real reliability of the data fingerprint.
