Abstract

Aiming at the problem that the generalization causes a large amount of loss of data information, and this defect would become more obvious as the data dimension becomes larger. This paper proposed an anonymous algorithm based on local partitioning. To ensure k-anonymity and l-diversity, based on the value constraint of sensitive attribute column and the distance between records, it horizontally divided the data table into several buckets. And then based on the relationship between the attributes, it longitudinally divided the buckets into multiple columns. Finally, it randomly rearranged the columns in the same bucket. The experimental results show that when dealing with high dimensional data, compared with LGAA-CP algorithm, it reduces the loss of information by 47% to 183%, and increases the retention rate of the relationship by 24% to 118%. Compared with the slicing algorithm, the loss of information between the two is within 1.5%, and it increases the retention rate of the association by 8.9% to 22.8%. The analysis shows that the algorithm is effective in ensuring both high-dimensional data privacy protection and data availability.
