Problems solved by technology

Blockchain technology can only guarantee that the data cannot be tampered with after it is uploaded to the chain, but the authenticity of the data before it is uploaded to the chain does not belong to the scope of the blockchain capability, and there is still a risk of malicious modification of the data before it is uploaded to other business platforms

Embodiment

[0023] like figure 1 , The block chain winding method of preventing data tampering, the method implemented by the hardware chain, said chain comprising a housing system hardware, CPU, Internet access module, data acquisition hardware interfaces, a near field communication module, the SAM the security module, the special data area A DT And hardware tamper module housing, the method includes the following steps:

[0024] Sl, chain systems and the hardware block chain mutual authentication node identification, authentication initialization is completed; the upper strand is connected by a hardware system with block chain 4G node. The near field communication module NFC, Bluetooth, Zigbee, one kind of 433M or 2.5G.

[0025] The process is as follows: on each of the chain block is assigned a unique hardware serial number block chain link ID is the serial number from the ID block chains 8-byte random number ID RQ +16 bytes directly fixed ID value CQ Composition prior to complete the init...

Abstract

The invention discloses a data tampering prevention blockchain uplink method, and the method comprises the following steps that S1, an uplink hardware system and a blockchain node carry out identity mutual verification, and initialized identity authentication is completed; S2, the uplink hardware system obtains the key data from the service equipment through the data acquisition hardware interface, and performs identity signature and encryption on the key data; S3, the uplink hardware system obtains the associated data from the communication device through the near field communication module, and performs identity signature and encryption on the associated data; S4, the uplink hardware system packages the key data and the associated data, performs identity signature and encryption on the packaged data, and sends the packaged data to the block chain node to complete data uplink. According to the method disclosed by the invention, the key data is ensured to pass through the verification and protection mechanism of the uplink hardware system before being uplink, and is directly uplink on the block chain node, so that the risk that the data is maliciously modified before being uplink through other service platforms is avoided, and the integrity and encryption of the uplink data are ensured.

Description

Technical field [0001] The present invention relates to block chain technology, and particularly relates to a method of block chains on the chain data tampering prevention. Background technique [0002] Block chain is a distributed data storage, new applications of computer technology point to point transmission mode, the consensus mechanism, encryption algorithm, which is essentially a decentralized database. After the block chain technology can only guarantee that the data link, the data can not be altered, but the authenticity of the data in front of the chain, is outside the scope of the block chain capabilities, data is still at risk of being maliciously modified chain before on other business platforms . Inventive content [0003] To solve the above problems, the present invention provides a method of strand chain block data tampering prevention. [0004] The present invention adopts the following technical solutions: [0005] Chain block chain A method of preventing the f...
