Smart Meters - Keeping Users Privacy

Alves Andre Luiz ,Fonseca Keiko Veronica Ono

Electric power distribution systems are evolving toward more intelligent models allowing distribution organizations to have a perspective on how consumption is happening. However, these systems may allow for violation of consumer privacy, as they can identify the equipment in use, allowing for profiling of user activities. This work addresses the need to develop a mechanism to protect privacy, and presents an option for creating this protection for individual electric power consumer units through intermediate encryption of readings from these individual units, allowing suppliers access not to individual readings, but sum of their total.
