Abstract: This paper presents a framework for secure two-party agglomerative hierarchical clustering construction over partitioned data. It is assumed that data is distributed between two parties horizontally, such that for mutual benefits both parties are willing to identify clusters on their data as a whole, but for privacy restrictions, they avoid to share their datasets. To this end, in this study, we propose general algorithms based on secure scalar product and secure hamming distance computation to securely compute the desired criteria in constructing clusters’ scheme. The proposed approach covers all possible secure agglomerative hierarchical clustering construction when data is distributed between two parties, including both numerical and categorical data.
