[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...
