Embodiment Construction

[0036] The embodiment of the present invention provides a method for detecting abnormal data of an embedded smart terminal and an embedded smart terminal, which can use the cloud-assisted method and use the graph clustering method to analyze the embedded smart terminal environment when the computing resources of the terminal device are limited. For small-scale abnormal data mining, the detection rate is high; the embedded smart terminal data has fewer attribute types, and the operating algorithm efficiency is higher. At the same time, the cloud collaboration method is used to assist the embedded smart terminal to perform secondary marking, which reduces the computing burden of the embedded smart terminal and improves the computing efficiency of the embedded smart terminal. In addition, the adoption of the technical solution of the present invention improves the problem that the traditional K-Means-based anomaly detection algorithm needs to preset the number of clusters, improve...

Abstract

The invention provides a detection method of abnormal data of an embedded intelligent terminal, and the embedded intelligent terminal. The detection method comprises: receiving data to be tested, wherein the data to be tested comprises the abnormal data; determining an object in the data to be tested, a k neighbor of each object and a k neighbor relationship between the objects; constructing a k neighbor directed graph according to the k neighbor relationship between the objects; constructing a k-clustering graph according to the k neighbor directed graph, and marking a clustering cluster in the k-clustering graph; and when a part of clustering clusters in the clustering cluster is meet preset conditions, outputting the data to be tested in the part of clustering clusters as the abnormal data. By adoption of the method, small-scale abnormal data mining can be performed in the environment of the embedded intelligent terminal by using a graph clustering method in the case that the computing resources of a terminal device are limited, the detection efficiency is high, the operation efficiency is high, and meanwhile the false alarm rate is reduced.

Description

technical field [0001] The present invention relates to the field of network security, and in particular to an embedded intelligent terminal abnormal data detection method and an embedded intelligent terminal. Background technique [0002] With the continuous development of Internet technology, network security has gradually become a hot topic, and new security threats are generated almost every day. Faced with such increasingly large-scale and varied types of attacks, it has gradually become a mainstream trend to apply machine learning or data mining technology to train and identify tens of thousands of new types of security threats. [0003] In the embedded environment, it is necessary to perform anomaly detection on some collected data, and many methods in the field of data mining can only show advantages when the data scale is large, such as neural networks, for environments with limited computing resources, The methods in the field of data mining appear to be more comp...
