Abstract : The advent of Smart Metering has facilitated the knowledge of fine-grained energy-consumption data. The data is transmitted over the internet which is prone to access by an undesired third party. The high resolution data gives information regarding the amount of electricity and the type of appliances used. Smart meters have also become potential surveillance devices that monitor the behavior of the customers. This has paved way for the need for powerful privacy preservation techniques. To ensure security, we introduce a technique of obfuscating the data before transmission by computing the DCT of the signal and adding a chaotic signal to it. The proposed approach is experimented on real household’s power signal data. © Research India Publications.
