Query: Multiparty Quantum Private Comparsion with Individually Dishonest Third
  Parties for Strangers   This study explores a new security problem existing in various
state-of-the-art quantum private comparison (QPC) protocols, where a malicious
third-party (TP) announces fake comparison (or intermediate) results. In this
case, the participants could eventually be led to a wrong direction and the QPC
will become fraudulent. In order to resolve this problem, a new level of
trustworthiness for TP is defined and a new QPC protocol is proposed, where a
second TP is introduced to monitor the first one. Once a TP announces a fake
comparison (or intermediate) result, participants can detect the fraud
immediately. Besides, due to the introduction of the second TP, the proposed
protocol allows strangers to compare their secrets privately, whereas the
state-of-the-art QPCs require the involved clients to know each other before
running the protocol.
