Abstract

The invention provides a personal computer using behavior monitoring method and system based on an acoustic communication channel. The personal computer using behavior monitoring method comprises thefollowing steps that 1, audio signals generated when a user operates a keyboard and a mouse are collected; 2, the collected audio signals are subjected to data preprocessing, and an audio signal blockis extracted; 3, feature data of the audio signal block are extracted and subjected to model training; 4, a trainer for model training is tested, and corresponding events are recognized; and 5, according to the recognized corresponding events, the using behavior of a user is analyzed. According to the personal computer using behavior monitoring method and system based on the acoustic communication channel, firstly, classifiers subjected to learning training are supervised, and meanwhile a model migration method is combined, so that the monitoring events are recognized, accordingly, based on event recognition, the great data basis can be provided for analyzing the activity that the user uses a computer, and the purpose of monitoring the personal computer using behavior of the user is achieved.

Description

technical field [0001] The present invention relates to a usage behavior monitoring method, in particular to a personal computer usage behavior monitoring method based on an acoustic channel, and a personal computer usage behavior monitoring system adopting the acoustic channel based personal computer usage behavior monitoring method. Background technique [0002] Nowadays, with the rapid development of computer technology, commercial-grade computers have become ubiquitous, whether in government agencies, various companies or schools, it has spread to every corner of life, especially the use of commercial-grade computers makes manpower Work efficiency is greatly improved. [0003] On the other hand, the research on acoustic event detection has also developed rapidly in recent decades, from speech background analysis to special acoustic event detection and retrieval. Existing research provides a basis for extracting high-level information by identifying the consequences of d...
