A privacy protection system for equipment inspection based on mobile terminals

Intelligence has become more and more popular, especially in smart grid. Nowadays, the inspection for power elements has changed from a traditional method to a more intelligent way using mobile terminals, which has greatly improved the work efficiency. However, this new method may reveal individual privacy such as workplace, work hours and personal habits, which may become background knowledge for attackers in the time of big data. In this paper, a privacy protection system for equipment inspection is proposed, including an improved algorithm based on k-anonymous algorithm, which can make privacy information anonymous efficiently, especially in fields with few workers.
