Today, the smart grid has been promoted globally. The smart meter always monitors the power consumption of each home to achieve precise control of the power generation and reduction of the unnecessary power usage. Full-time monitoring leads the risk to disclose users daily activities derived from the gathered data. In the previous work, a home power rechargeable battery is introduced to conceal the activity of each appliance. However, the battery requires special function to mixture arbitrary amount of the charged power to the power from line. The proposed algorithm did not manage the amount of the charged power, then concealment does not work when the lack or fill of the battery occur. In this paper, we propose a power activity concealment system using UPS and smart tap which camouflage the power consumption as a square waveform, random waveform, and mixture of them. The battery charged status is used to control the camouflage to keep the control well. We achieved 0.33 points improvement on the coefficient of determination on concealment.
