Module for collecting credible data and data transmission method

Abstract

The invention provides a data acquisition module and a data transmission method. An embedded system, a security module and a plurality of sensors are arranged in the data acquisition module. The sensors are responsible for data acquisition, and after completing the data acquisition, sending the data to the embedded system; the embedded system sends the data to the security module; the security module encrypts the data to form a data signature and sends the encrypted data signature to the embedded system; and the embedded system sends the encrypted data signature to a block chain node. According to the system and the method, no manual operation is not carried out in the data chaining process, hardware security, block chain security and a data acquisition scene are combined, and the system and the method have good applicability. By means of the blockchain technology, the data can not be tampered with, the security is high, and compared with the prior art, the trusted data collection andtransmission can be completed with high efficiency and low cost.

Description

technical field [0001] The invention belongs to the technical field of blockchain, and relates to a module for collecting credible data and a data transmission method. Background technique [0002] The blockchain is essentially a reliable database maintained in a decentralized manner. It is a series of data blocks generated by cryptographic methods, which ensures that the data added to the blockchain is permanently stored. Once stored, it will not It is easy to be tampered with, and the data is open to everyone, all information is highly transparent, and transaction records can also be traced. It provides us with a globally trusted notebook and a global clock, which is updated when new blocks appear, and each block can also be uniquely identified by the hash value of the block's header. [0003] Usually, the data collected by IoT devices (sensors, smart homes) is processed by the edge end + center end, but in the process of storage and transmission, it is easy to be tampere...
