The use-case presented in this paper is to find the common customers of two or more organizations without revealing any information to third parties. In the real world this could be used by insurance companies or financial institutions to determine risk and detect fraud, or by retailers for cross-selling offers. However, there are other applications of the technology, some already applied in practice. For example, some chat messengers use similar techniques to see if two users have common contacts in their contact lists. Another option is to perform secure database join based on the customer’s data available in both databases, thus extending one with the data from the other but only for the common rows.
