Abstract

The embodiment of the invention provides a sensor data authentication method and device based on a block chain. The method comprises the following steps: acquiring sensor data in a block generated bya data node; inputting the sensor data into a consensus neural network architecture to obtain a probability value which is output by the consensus neural network architecture and represents the credibility of the node data; and if the probability value is greater than a preset probability threshold, adding the block to a block chain. By adopting the sensor data authentication method based on the blockchain, disclosed by the embodiment of the invention, the authentication efficiency of the sensor data can be effectively improved, and the credibility of the data flow in the network is ensured, so that the reliable acquisition, transmission and use of the sensor data are realized.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a sensor data authentication method and device based on blockchain. In addition, it also relates to an electronic device and a non-transitory computer-readable storage medium. Background technique [0002] In recent years, with the rapid development of the Internet of Things technology, various types of sensor devices have been used more and more widely in the field of monitoring. The existing sensor network aims to enhance the perception state quantity through sensor networking, realize the improvement of the perception range and accuracy, and ensure the authenticity of the data of each node in the network is the basis for the normal operation of the sensor network. However, there are many equipment management and data security problems in the large-scale deployment of sensor networks. For example, in the process of sensor data collection, transmission and storage...
