Quality criteria of anonymous publishing table based on entropy
基于熵理论的匿名发布表质量度量方法研究*

Measure criterion of published micro data is an important factor of anonymous models.Common measure criteria were studied in attributes hierarchy and record number view,which had obvious defect.Based on entropy theory,this paper designed a set of equation refers to quasi-attributes weight and domain to measure the utility of privacy preserving and information loss.Theoretical analysis and experimental results show the measure criteria is more accurate.
