Embodiment Construction
[0052] In order to make the objectives, technical solutions and advantages of the embodiments of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.
[0053] Please refer to figure 2, this application proposes an improved IoT architecture based on blockchain. Through the scalable IoT gateway, it supports the storage and uploading of high-concurrency IoT data, and can also integrate multiple IoT device data to achieve accurate Anomaly analysis of Internet of Things (IoT) devices.
[0054] figure 2 The IoT gateway is a BoT node (Blockchain of Things, IoT blockchain). Each IoT gateway includes three modules: IoT device registration, IoT data compression, and IoT anomaly detection. The IoT device registration module is mainly responsible for registration. For IoT devices, the IoT data compression module is mainly responsible for compressing and uploading device dat...

The invention discloses an abnormal data detection method and device based on a block chain, a storage medium and a gateway, and belongs to the technical field of block chains. The method comprises the steps of obtaining device data and a device identifier sent by an Internet of Things device, and obtaining an exception model corresponding to the device identifier and stored on a block chain; performing anomaly detection on the equipment data by using the anomaly model to obtain abnormal data, forming abnormal information by using the equipment identifier, the abnormal data and the Merkel proof of the abnormal data, and performing uplink storage on the abnormal information; obtaining an abnormal model and an equipment identifier list under scene information corresponding to the abnormal model, wherein equipment identifiers in the equipment identifier list are added to the scene information by a user according to a scene where the Internet of Things equipment is located; screening out the abnormal information containing the equipment identifier from the abnormal information stored on the block chain; and updating the abnormal model by using the screened abnormal information. According to the method, the analysis efficiency of the abnormal data can be improved, and the accuracy of anomaly detection can also be improved.
Description
technical field [0001] The present application relates to the technical field of blockchain, and in particular, to a method, device, storage medium and gateway for detecting abnormal data based on blockchain. Background technique [0002] Blockchain technology has important characteristics such as non-tampering, decentralized network, consensus algorithm and automatic execution of smart contracts, which can solve the problem of trust between multiple parties. Therefore, it is suitable for the application of IoT multi-device integration, so there are figure 1 The blockchain-based IoT architecture shown. [0003] Limited by the weak analysis capability of the IoT gateway, even if a Mobile Edge Computing (MEC) module is attached to the IoT gateway, it can only analyze the current IoT information related to the IoT gateway, which requires certain It takes time accumulation to analyze abnormal data, and the accuracy of abnormal data analysis is not high.
