We propose a low power extraction method of Echo-Hiding audio steganography. Our intermittent power control strategy enables to reduce the active time of devices including processor, ADC, and sensors. Our strategy consists of two features; majority-rule extraction method reduces the active time during extraction, and intermittent watermark detection enables the devices to be almost powered off in the environment without watermarked audio. In the experiments, our method reduced the active time of the processor and ADC to 60-70%. Also, in the environment without watermarked audio, our method was able to reduce 99% of the active time.
