An Efficient Anonymous System for Transaction Data
k-anonymity is an efficient way to anonymize the relational data to protect privacy against re-identification attacks. For the purpose of k-anonymity on transaction data, each item is considered as the quasi-identifier attribute, thus increasing high dimension problem as well as the computational complexity and information loss for anonymity. In this paper, an efficient anonymity system is designed to not only anonymize transaction data with lower information loss but also reduce the computational complexity for anonymity. An extensive experiment is carried to show the efficiency of the designed approach compared to the state-of-the-art algorithms for anonymity in terms of runtime and information loss. Experimental results indicate that the proposed anonymous system outperforms the compared algorithms in all respects.
