Data transceiving method and device based on HDD hard disk

The invention provides a data transceiving method and a data transceiving device based on a computer HDD hard disk. The method comprises the following steps: modulating to-be-transmitted data into anaudio signal, and enabling the audio signal to change the data transmission state of the hard disk; and monitoring a data transmission state of the hard disk, and demodulating according to the data transmission state to obtain a data signal. By adopting the technical scheme of the invention, firstly, the limitation of network isolation can be effectively broken through, and data communication is realized; and secondly, the problem that the conventional means is easy to monitor and discover can be avoided. And 3, data transmission can be realized in a relatively hidden manner. 本发明提出一种利用计算机HDD硬盘的数据发送接收方法及装置，所述方法包括：将待传输的数据调制为音频信号，使得所述音频信号改变所述硬盘的数据传输状态；监控所述硬盘的数据传输状态，并根据所述数据传输状态解调得到数据信号。采用本发明的技术方案，一是可以有效突破网络隔离的限制，实现数据通信。二是可以避免常规手段容易被监控和发现的问题。三是能够以较隐蔽的方法实现数据传输。
