摘要
目前动态数据的隐私保护引起了人们的广泛关注。m-invariance概念的提出,比较好地解决了动态类别敏感属性的数据隐私保护问题,但对于动态数值敏感属性却未取得任何进展。描述了动态数值敏感属性的数据隐私保护问题,提出了解决该问题的m-increment概念及其泛化算法,并通过实验数据说明了算法的实用性和效率。
A lately privacy preservation for dynamic data has attracted great attention. The concept of m-invariance was proposed and solved the problem of data privacy preservation for dynamic categorical sensitive attributes, but it made no progress for dynamic numerical sensitive attributes. This paper analyzes the problem of data privacy preservation for dynamic numerical sensitive attributes, and then proposes the concept of m-increment and the corresponding generalization algorithm to solve the problem. Finally, the experiments demonstrate the effectiveness and efficiency of the method.
