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 As shown in the figure, a data tamper-proof blockchain method is implemented. The method is implemented by an on-chain hardware system, and the on-chain hardware system includes a shell, a CPU, an Internet access module, a data acquisition hardware interface, a near field communication module, and a SAM. Security module, special data area A DT and a hardware shell anti-disassembly module, the method specifically includes the following steps:

[0024] S1. The on-chain hardware system and the blockchain node perform mutual identity verification to complete initial identity authentication; the on-chain hardware system is connected to the blockchain node through 4G. The near field communication module uses one of NFC, Bluetooth, Zigbee, 433M or 2.5G.

[0025] The process is as follows: The blockchain assigns a unique blockchain ID serial number to each on-chain hardware system, and the blockchain ID serial number consists of an 8-byte random number ID. RQ +...

Abstract

The invention discloses a method for uploading a blockchain to prevent data tampering. The method includes the following steps: S1, the hardware system on the chain and the blockchain node perform mutual identity verification to complete the initial identity authentication; S2, the hardware system on the chain Obtain key data from the service device through the data acquisition hardware interface, and perform identity signature and encryption on the key data; S3, the on-chain 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 on-chain hardware system packages the key data and associated data, signs and encrypts the packaged data and sends it to the blockchain node to complete the data on-chain. The method of the invention ensures that the key data is directly linked on the blockchain node through the checksum protection mechanism of the on-chain hardware system before going on the chain, avoids the risk of malicious modification of the data before going on the blockchain through other business platforms, and guarantees Integrity and encryption of on-chain data.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain method for preventing data tampering. Background technique [0002] Blockchain is a new application mode of computer technology of distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. It is essentially a decentralized database. Blockchain technology can only guarantee that the data cannot be tampered with after the data is on the chain, but the authenticity of the data before it is on the chain does not belong to the scope of blockchain capabilities. . SUMMARY OF THE INVENTION [0003] In order to solve the above problems, the present invention provides a blockchain method for preventing data tampering. [0004] The present invention adopts following technical scheme: [0005] A method for data tamper-proof blockchain on-chain, the method is realized by on-chain hardware system, and the on-chain hardwar...
