Title
(EN) Data storage method and device based on block chain and electronic equipment
(ZH) 基于区块链的数据存证方法及装置、电子设备
Abstract
(EN)
The invention discloses a data storage method based on a block chain. The data storage method is applied to pluggable equipment in butt joint with terminal equipment. The pluggable equipment carries asafety operation environment; a private key corresponding to the pluggable equipment is stored in the security operation environment; the method comprises the steps of obtaining a data abstract of target data collected by terminal equipment; signing the data abstract based on a private key corresponding to the pluggable equipment in the secure operation environment; issuing the signed data abstract issued to the block chain, so that node equipment in the block chain verifies the signature of the data abstract based on a public key corresponding to the private key; and after the signature verification is passed, subjecting the data abstract to data storage in the block chain.
