Zusammenfassung: | The invention discloses an environment intrusion detection method and system based on WiFi. The method comprises the following steps: firstly, acquiring signals in different invasion environments andpreprocessing the signals; preprocessing data, performing feature extraction on the preprocessed data by using a self-organizing neural network algorithm, classifying feature values by using a Softmaxclassifier, establishing an intrusion fingerprint library, finally matching the acquired data in a to-be-detected environment with fingerprint library data online, and judging whether intrusion exists or not. According to the invention, the security monitoring function is realized by using the existing WiFi network, the coverage range is wide, and the privacy is not exposed. Experimental resultsshow that the recognition rate of the method is greatly improved, and the method has a good development prospect.
本发明公开了一种基于WiFi的环境入侵检测方法和系统。本发明首先采集不同入侵环境下的信号并进行预处理,然后利用自组织神经网络算法对预处理数据进行特征提取,采用Softmax分类器对特征值进行分类,建立入侵指纹库,最终在线将待检 |
