Data security verification method and device based on block chain

Abstract

The invention discloses a data security verification device based on a block chain. The device comprises a protection outer box, a positioning mechanism and a memory box. The device is characterized in that the protection outer box comprises a box shell and a sealing door plate, wherein a viewing port is arranged in the front end surface of the box shell; the sealing door plate is arranged in themiddle of the viewing port and is in longitudinal sliding connection with the box shell; and the positioning mechanism comprises a mounting base and a locking mechanism. According to the method and the device, a user can place objects needing to be stored in a box body stably when used, a sealing cover is stably buckled on the box body, and the safety of the objects in the box body is guaranteed;after the user buckles the sealing cover, the mounting base can drive the box body to stably rotate under the drive of a reset spring; and when the sealing cover rotates to the position opposite to the viewing port, the sealing cover stops rotating, and when the user opens the sealing cover, if the mounting base does not rotate, the objects cannot be taken out of the box body.

Description

technical field [0001] The invention relates to the technical field of data security verification equipment, in particular to a blockchain-based data security verification method and device. Background technique [0002] Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain is essentially a decentralized database, and at the same time, as the underlying technology of Bitcoin, it is a series of The data blocks associated with cryptographic methods, each data block contains a batch of bitcoin network transaction information, which is used to verify the validity of its information and generate the next block. In a narrow sense, the blockchain is A chained data structure that combines data blocks in a sequential manner in chronological order, and a non-tamperable and non-forgeable distributed ledger guaranteed by cryptography. Broadly speaking, blockchai...
