This paper introduces the main anonymity preservation models, reviews the advances of the existing anonymilization-based privacy disclosure techniques in data publishing according to the idea of their algorithms, analyzes the limitations of the current techniques, and gives the future research directions.

The result of the experiments suggests that the new model is able to reduce privacy disclosure apparently and enforce security of data publishing.
