Abstract
In the information age, people’s various behavioral data are collected in large quantities. The sharing of information makes it convenient for some scientific investigations, but there is a leakage of personal privacy at the same time. The current research on privacy preservation is mostly based on relational tables or social network graphs. This paper focuses on semi-structured data, which is often ignored in privacy preservation. We propose a new privacy guarantee called X-km-anonymity and propose a bottom-up heuristic algorithm that provides protection by satisfying X-km-anonymity. We verified the feasibility of the algorithm through a reliable utility analysis method on the simulation data.
