Abstract: There exist many scenarios where multiple parties jointly work on some common project but these parties are not interested to show actual value of data to each other. Here we propose an algorithm where multiple cooperating but distrustful parties can compare their data for equality without disclosing it to one another. This is an improvement over two party comparison algorithm devised earlier by other researchers. The proposed work is suitable for semi honest adversaries who respect rules of the protocol but somehow try to know private values with other parties.
