MA-Datafly:k-anonymity approaches for supporting multi-attribute generalization
LV Pin · Computer Engineering and Applications Journal · 2013
Datafly algorithm is an k-anonymity method for protecting data privacy in privacy preserving data publishing, the most frequent attribute of quasi-identifier attributes is generalized when realizing k-anonymity. Datafly algorithm can be executed when the values of an attribute of quasi-identifiers are diversity and the values of the other attributes are homogeneity. However, the character is impossible in practical applications. According to the problem, an bottom-up generalization algorithm for supporting multi-attribute is building. Experimental results demonstrate that the developed algorithm is efficient for solving information loss and elapsed time.
