摘要: 为使微数据发布在满足K-匿名要求的同时提高匿名数据的精度,提出多维泛化路径的概念及相应的2种K-匿名算法,包括完整Filter K-匿名算法和部分Filter K-匿名算法。将它们与Incognito算法和Datafly算法进行比较,实验结果表明2种算法都能有效降低匿名信息损失,提高匿名数据精度和处理效率。

Abstract: Microdata publication need satisfy the basic K-anonymity requirement as well as improve the precision of anonymized data. This paper proposes two related K-anonymity algorithms based on the notion of multi-dimensional generalization path, namely K-anonymity Filter algorithm and K-anonymity partial Filter algorithm. In comparison with classic Datafly algorithm and Incognito algorithm, the two algorithms offer more efficiency for both reducing anonymization cost and improving data precision.
